I have an LO 3 motor and am currently running 15.74 with the few mods i did, what will a 120 hp shot of nitrous yield in the qtr if the bottle is at the right pressure?

 

You will blow your engine sky high with a 120 shot.

Maybe not though.... of course 50-75 shots would definitely be fine.

 

I would see about getting new pistons if you use NOS. Exspecialy if your going to use it alot. 75 shot would be ok for a while with stock engine. Anything higher I would go for new pistons.

There are a couple of guys running 125 -150 HP shots on their stk 305TPI engines. I would ask them (Power Adder Board). The key is not going lean. A healthly fuel system is a must.

 

I asked one guy here a while back and he said he gained over a full second on a 120 horse shot.
Like 1.1 seconds I think.
That thing better be tuned to the max first though.

With a bad O2 sensor(which made my car run around a second slower than it should) my car ran a 16.7 at 82mph. With 3.42 gears. On the bottle with my 125hp shot I ran a 14.48 at 97.5mph letting it shift itself at 4000rpms and only hitting the button once I hit second gear. I could have run a low 14 or high 13 at 100mph if I would have held it in gear to 4500 and hit the NOS off the line. I used to not have posi and the tires would smoke from a 25mph roll I didn't know if the tires would do this with posi that's why I didn't hit it in 1st. Found out later they just chirp with the posi if I hit from a 5-10mph roll.

 

hey Mike, why don't u tell everyone what happened to that engine u just told us about running those times.

Saying Nitrous blows engines is just ignorance. You can blow an engine with just too much air and not enough fuel. Nitrous simply exaggerates both of these factors. Now dont go bolting up a 300 shot to your 305, stock connecting rods and parts cannot handle all of that extra horsepower even with enough fuel. THe cylinder pressures become too great for stock peices
The reason a 125 shot could blow a motor is because of detonation or fuel starvation OR the motor was old and worn and the extra cylinder pressure nitrous provided accelerated its death. Nitrous is completely safe when used intelligently.

Of course some people have a problem with that.

 

pablo u dont think NOS is bad enough on a motor to blow it?? I know i personally wouldnt run more than a 75 shot on the stock motor with n e kind of mileage on it. I think a 125 shot would work fine for maybe 2 bottles but once the third and 4th bottle come into play that rod knock will start to show its ugly face.


Nitrous is completely safe when used intelligently.
Of course some people have a problem with that.

well n e way u look at it NOS isnt all that good for a motor. As soon as that shot comes through the motor and that thing revs up to red line u r askin for a rod to shoot through the oil pan. Its not kool to imply that someone isnt intelligent becouse they dont know how to use NOS.
Isnt that y they asked the question?? to find out about NOS.

nos is like a supercharger in a bottle

just like a supercharger can damage a motor
so can nos

its all about stopping detonation from happening and always having enough fuel

The only way nos is hard on a motor is simply because its making the motor put out alot more hp than stock. take two cars that run 13.5, stock bottom end
one of them does this naturally aspirated
one of them does it with a 100 shot of nos

The nos car is no harder on the bottom end than the naturally aspirated car the build the same (similar) cylinder pressure, and if there is no knock and there is alwasy sufficient fuel they will both last the same amount of time (the nos motor probably longer actually)

the idea that "nos blows up motors" is a myth born out of ignorant people using it incorrectly

 

so as for your comments about putting nos on a motor with mileage

you have to consider nos like heads and cam

same thing in terms of cylinder pressure

if a motor with mileage will blow with a 75 shot of nos and its not because of detonation, then that same motor will blow with 75 hp worth of heads and cam
same principal here

 

Ok, just ask that Mike guy, his LO3 didn't last very long. Go to the Power adder board and ask them this question camaroracer1992. They would know.

I was told earlier that if you want to run a 100+ shot of NOS on an engine and you want to be completley safe you have to have strong Rods, strong pistons and knowing how to stop detenation. So far, we are missing the first 2 in our engines.

how about we ask the hundreds of people that have used nos on stock motors for years without any problems? Off the top of my head, talk to Quick305 with the black iroc, nos'ed LB9 for as long as i can remember

 

Isn't that what I kinda just said?

 

ok bottom line NOS is not good for a motor. Pablo go drop a 120 hp shot of nos on ur car and see how long it lasts. Its an increadible amount of force on n e motor(unless built) and it will cut the engine life in half. Thats pretty retarded to compare heads and cam to NOS. Heads and cam make NA hp which isnt nearly as hard on the motor as NOS.

 

Doesn't NOS clean out your engine though? I have heard it does that. I just think whoever wants to do it to go over to the Power Adders board and see what they say. There would be someone over that would know for sure cause they probably did it.

Yeah, to say that two cars that run the same times will have same HP and, therefore, cylinder pressures is dumbass. Saying that an NO engine can/should last longer than a naturally aspirated enigne is dumbass, too. Man. Unless, of course, PABLO has never used or experienced NO. Nor does he have a high cylinder pressure, high HP car. Nor can he make over 220 hp on a good day. Nor can he run respectable 1/4 times...

The 'flip-of-a-swithch' pounding of NOS is a force to be taken prudently, unlike normal high cylinder pressures of a NA 11:1 CR engine. man

 

There you go with your assumptions

Quit making an *** out of u and me

 

There you go with your assumptions
Quit making an *** out of u and me


lol umm no i think he made an *** out of u

 

Sorry to say it, but I think some of you guys need to go do some studying and come back when you learn a few things. Pablo is right, its all about cylinder pressure. It doesn't matter if its from heads, cam, etc., or from nitrous. The reason so many people blow up motors with nitrous is just plain stupidity. I'm sure that if Pablo put nitrous on his car he would have the sense to set it up right and the car would run great. A properly tuned engine with a reasonable level of nitrous will last a very long time. I'm currently running 125 hp through my motor with no problems, and I'll probably be stepping it up to 150 in the spring. Don't start talking **** until you know what the hell your talking about in the first place.

 

This would be a good topic on the POWER ADDERS board. I don't know to much about NOS but I was told by others that run NOS on their cars that you have to have strong rods and pistons and know how to prevent detenation. I guess if anyone wanted to know how to go to the power adders board or have Pablo move this over there. Makes more sense to me that way I guess.

if you want this over there then post it over there.
My question is if cyl pressure differences are different because nos is an "instant hit" how is that different than slamming your foot to the floor from a 3000 rpm cruise on a motor with 100 hp worth of mods?

Im no nos expert, but I dont think it is that much different, champ.



[This message has been edited by Pablo (edited November 06, 2000).]

 

Dude, your the moderator, why don't u move it over there? Champ.

 

I dont know much about nos personally but i did talk to my mechanic who has been drag racing for longer than anyone i know. He is a good friend of mine. Pablo is right my mechanic basically said the same thing. In fact he told me to go with a 125 or 150 shot and said i could probably go a little higher if i wanted to. So i ask him then if it wont blow my engine will it make it wear faster. He replied no as long as you have enough fuel going to you engine and are not stupid it wont affect it at all.This guy knows his stuff he used it for years on his cars and his drag cars. It is a not a myth that it blows your engine because you can it is very easy he even blew one of his engines and the reason for that was because his fuel line was crappy and the enginge wasn't getting any fuel.Other than that it should be fine. I am probably going to be putting nos on my engine which is a stock 305

 

A friend of mine had NOS on his stock engine. He was a speed freak. Anyways, his fuel pressure drop (very slightly), while he was in the middle of a NOS burn, and he ended up melting his pistons. I dont know much about NOS, but from stories Ive heard, I plan on building an engine up with high HP. Then getting a super-charger a few years down the road. I don't want to mess with NOS, besides that you have to fill the bottle up, its pretty expensive up in Canada for a shot of NOS. I dont think NOS is worth it.

 

Yeah, I guess you kinda gotta ask yourself. Is NOS worth it? Cause there is a chance I could melt my pistons or something else you know? I don't think it is worth it on a stock 305. Cause think of it.

170+100 shot of NOS leaves you at 270hp.
Hell, even with a shot of NOS you still would get beat by any LT1 or LS1. Guess if you modded your 305 first then it would be a better result. My car is a daily driver (except winters) so I couldn't risk it.

I personaly think that anyone planning on putting NOS on any 305 or 350 stock motor, with TBI should save the 600 dollars and put hat towards a motor that will grant 400 hp. Spending 5-6 hundred just for the kit on a 175-200hp motor on average is wasting your money. The way everyone is talking, it seems that everyone is unsure about how to use NOS correctly anyway. Put your money towards a new motor, because in the next year you'll be rebuilding the current motor anyway. I spent a lot of money just building a 383 stroker w 450 hp for my 91 camaro rs using a TBI from Turbo City and custom burn chip for my application and I am glad now that I did not spend a lot of money on NOS or a supercharger. You also have to spend tons of money on fabricating your car and motor to run NOS or a supercharger. Thats just my thoughts any way.

I doubt that this was the answer he was looking for. He probably wants cheap HP. The key word being "CHEAP". i dont think that a brand new motor is cheap. Let alone a brand new Built up motor.

 

It will be cheaper down the road. Cause the engine isn't going to last long anyways with those internal pieces of crap that come on the LO3. So why not save up and get a crate motor with a crate motor you will be starting at where u would be at with the NOS on the 305. Then down the road when u save up more money u can throw NOS on the crate engine and you will create more hp then u could EVER create with the LO3, even with NOS on it. And the crate engine wouldn't blow as long as it has strong rods and pistons and the owner knows how to prevent detenation.

Hehehe funny you mention the "Piece of crap parts in the LO3" You ever taken one apart? Hmm...very interesting...they have pretty much the same internals and a tpi 305. The cranks are the same material as almost any GM produstion smallblock. The rods, in my opinion, and a few races that build high revving circle track engines are some of the strongest rods made by GM, there beefy. The LO3 block is nearly indestructable. Rip apart any 200,000 LO3, wow, neato, yipee minimal ridge and theres still cross hatches in the bores. The rings die long before the block will. The pistons, like any mid 80's to early 90's smallblock leave some strength to be desired, but they work well. The only things that truly suck on a LO3 are the heads, cam, intake, and TBI Unit. The heads make good paper weights. There not even worth trying to port. Your mom could use the cam as a rolling pin. The intake, it's aluminum.....a scrap yard would give you money. The TBI unit, is however, saveable. The ultimate TBI is prolly good up to a healthy 350 horse, and with a decent fuel system and some bigger injectors...who knows??? However I will probably wait for that redesigned TBI....it sounds like a real world piece. Address the real problems of the LO3...induction.

91Bird305 Here are some comments made by you.





It is quite clear that you like to talk about things you know nothing about.
Spreading bad info is a lousy practice and I urge you to stop.

In quote 3 you even admit that you know very little about N20 so why are you making a statement such as quote 1?

Next you talk about the rods and pistons. Do you have any idea how much horsepower the stk lowerend can withstand? If not, then don't make wide sweeping statements.

 

Dude, shut the hell up. Go take ur flame somewhere else. This topic has long been over with Brent.

In my first quote ya got there, I said that cause he was just going to put a 120hp shot on a stock engine with no plan of how to stop detentation from happening. Thats why I said, "u will blow ur engine sky high." And he would w/o the right precauctions. As for the 2nd quote I was just simply stating what I have heard from people that use NOS. Had nothing to do with my first quote. That was after he stated he would do the stuff that we talked about, preventing his engine from going. 3rd quote just the same but I just suggested to move it to the power adders board since they would know best, what is wrong with that? 4th quote I just stated that it would be better to save up for a crate engine then put NOS on an engine that isn't prepared for NOS. Thats all. And it is a better idea. Why put a 120hp shot of NOS on a 170hp engine to make it a 290hp engine on the bottle??? He could just might as well save up for the crate engine and start out with 330hp or 385hp on the motor and then work with the NOS later on.
Whats wrong with that idea?

Try going to 3rdgen.org and into the fight club if u want to pick a fight with someone Brent otherwise, no your roll and shut your mouth.

Anyone watch wrestling in here? Nevermind, thats non-tech.

Natzke, you don't know when to be quiet do you. The more you talk, the more you look like a horses *** .

Really? Your previous post was posted November 14, 2000 06:04 AM. Today.

There is no mention of any of those things, only that a 120hp shot will blow his stock engine. False.

You infered that the stock rods and pistons are weak and won't tolerate the nitrous. False. The 305 lower end will easily tolerate 300hp.

Nothing. That quote showed that you ADMIT knowing very little about n2o.

Your opinion. Nothing wrong at all with spraying a stock engine. Nitrous delivers the most power per dollar as a bolt on period.

You also said (again) that the 305 bottom end is crap. You do not know the limits of the stock pieces so how can you make that statement?

LMAO You've been called out. Suck it up!

 

also keep in mind eric that it wont take the same amount of power to beat a 4th gen. They are heavier and alot less areodynamic. I think 290hp would take out any stock LT1 and a close race with the LS1. Trust me i drove an LS1 and they are by far gods gift to cars. They are very fast granted but its not impossible to keep with them. They just have a stock 5.7 with well thought out engineering. Nothing we couldnt do with our little 5.0's

 

Quote me....please. I love it. Call me out over at 3rdgen.org. If i say another swear word Pablo will probably kick me out of thirdgen for good. I will keep my cool and won't quote everything u posted and more. But please, quote something from this reply too. It is soooooo cool.

I never said I knew anything about NOS, I just said from what I have heard, thats all. <--Quote that please.
Never said I was the CEO of NOS and I am the NOS GOD and I know NOS! No, I just made suggestions and comments on certain statements other people have made from previous threads on this subject. So why would u say that? Just leave it alone man. Geez, calling me out on NOS, yah, sweeeeeet. Brent, you are a coooooool dude. Like I said, take your flame somewhere else, it isn't going to get u anywhere over here, this is a tech board, not flame board.

So now that is over, please enlighten everyone with your NOS knowledge. Cause u must be very knowledgable if you like to pick apart people's opinions and comments and tell them they are horse's a$$'s and they know diddly about NOS, when they never said they did, all they were doing was trying to help out with past info. But thanks. By the way, nice to meet ya.

[Edit]
Yeah, your probably right Mike. Probably would be able to keep up with an LT1 with a 120hp shot.
I know, LS6's are now.

Sweeeeet

 

DAHAHA

this is a good post.

as for tech: why would a 170Hp engine be getting NOS? With full exaust and open element it should be pushing 220hp+ as Andy89RS has found from his 1/4 mile MPH

a 290 hp 3rd gen will take out n e stock LT1 4th gen and that is that. Aside from the 3rd gen being lighter the 4th only has 275hp and 305 in ram air form. I believe it would also take on a non ram air LS1. Give these cars a little more credit. It dont take a ZZ4 to beat a 4th gen. Sorry if this sounded like i was being a **** . I was really not trying to be its just that u are way underestimateing these motors. I mean some of the times u told me that TBI is supposed to run (16.5+) are the same times as the guys over on the V6 board. sorry man, plz no hard feelings, i was only tryin to speak my mind bro...

TAS 220 hp out of open element and full exahaust?? does that include headers ?

 

Since I have no idea what ur talking about Mike I will say....Ok
And yes, the 94 LT1 has 275hp but after 95 the LT1 was rated at 285hp. It doesn't really matter though, its only 10hp so forget I ever said anything about all that.

As for a ZZ4 not being able to take a 4thgen, why do u say that? ZZ4 has 355hp and 405lbs of torque. Those ratings sound good enough to beat a 4thgen and a LS1 to me. We will have to see though when the time comes.

As for the potential of the LO3. Yeah, it has a lot of potential, as long as your willing to change the entire engine block and add some nitrous and do all that work for a 305 and realize if u had more cubic inches and u did all that same work to that you would be pushing more power out. (oh man, I said the nitrous word, hope Brent doesn't quote me!)
So by all means, create a strong 305, that would look great for us u know? But I am not willing to dish out the money for it and so far, I haven't seen anybody really but Pablo do most of it and he doesn't even have a time slip for us. Its just that I haven't seen one of "us" really do the things we always talk about. The whole thing, like heads,cam,intake,tb unit, custom chip, and so forth. I don't know, I might be wrong, is there someone out there that has done this to their LO3 and do they have a time slip or somethin to tell us how big of an improvment it made? We should probably make this a different thread. We have gotten off the subject a bit.

[Edit] Hey Tas, what is Andy running now? Doesn't he run a 15.4 or did he run something lower now? Andy, where u at?

ya full exaust means headers, high flow cat(or no cat), and catback.

I don't remember Andy's ET.

If my 5.0 had lower miles I'd go nuts on it like pablo but I got 151k miles now. Also, I don't want to get headers for it because it needs and 1-5/8" ones and when I get my 350+ engine I will DEFINATELY(sp?) want 1-3/4"

 

Yeah, I will probably will have to use those 1-5/8" Edelbrock's until I get enough money for some SLP 1-3/4"

 

eric i never said that the ZZ4 couldnt take out the LS1 i was saying that u dont need one......................thats all for tonight, im way to tired to talk cars

 

I would like to see a stock L03 with 120 shot take on a 4th gen car. The l03 might beat him for the first few races, but after the pistons melt in the L03, I think the guy in the 4th gen will be laughin last.

 

OK...hate to pick on you again bird. For under a grand I will be able to run with ANY LT1. No nitrous, huffers, or hair dryers. L31 vortec heads (shaved .050 and mildly polished), decent cam, nice intake, Ultimate TBI, open element, a fat *** chip, (I admit I only paid 25 bucks for the headers) hooker supercomp shorties, and a full 3" exhaust. I'm shooting for 270+ hp and 330+ ft lbs on torque.

Phil-

P.S. and it IS cheaper and more cost effective than ANY crate engine.

------------------
91 RS with an auto TBI 305. Metallic Maui Blue, Iroc nose and hood 40,000 on the ticker. No engine mods as of yet. I want a turbo....bad.

 

Ok, thats great. But now look at your setup and look at the LT1. First thing I notice.

1. You have changed your entire block and computer system to aftermarket parts.

2. I look at the LT1. He is TOTALLY stock at 285hp.

3. You have no more potential but NOS.

4. LT1 can change his entire block with aftermarket parts just like u did and now you would be back to where u were.

I don't mean to pick on your idea or anything. It sounds like a great idea for a 305 and thats cool that u did it. (u did it right?) But I would rather start out with 355hp and have lots of room for potential then start at 170hp and top out at around 300hp and have no more room for improvements because I have already done them all to get there. Know what I mean?

[EDIT]
By the way, I comend you for working on your 305 like that. I think thats great someone here has really taken the time and money and knowledge to do it all to their 305. Now go time that sucka and lets see what she runs!

1. You have changed your entire block and computer system to aftermarket parts.

no....when i do it the block and internals will remain. Heads, intake, cam and a computer CHIP. not a whole new computer.

2. I look at the LT1. He is TOTALLY stock at 285hp

ok is the LT1 the base line for a performance car or something. I mean if its so great y dont u just sell ur car and buy one. U should get enough 4 one.


3. You have no more potential but NOS

ok so ur saying that a L03 motor isnt fast unless its on NOS?? no more potential?? what about a blower? U could easily get a NA 305 to puch 300hp. Drop a shot or some boost on that and tell me where that would leave u....honestly

4. LT1 can change his entire block with aftermarket parts just like u did and now you would be back to where u were.

again i say is LT1 the baseline for a performance car??


I don't mean to pick on your idea or anything. It sounds like a great idea for a 305 and thats cool that u did it.

no pick away its all good. It sounds like a great idea for n e motor, not just a 305.

(u did it right?)

nope....i just have a solid plan of action for when i decide i feel like doin a motor.


But I would rather start out with 355hp and have lots of room for potential

dont u think that gm did all those HP improveing mods? I mean its not just some 350 that magicly produces 355hp. Its modded already, Leaving n e more hp potential minimal unless bottle fed or blown


at 170hp and top out at around 300hp and have no more room for improvements because I have already done them all to get there

again i say.........y did u buy the car if u want to start with more than 170hp. Who said n e thing topping out at 300hp on a 305?? ur seriously telling me that u "think" the 305 wont top out more than 300hp? So is that magic 45 cubes from a 305 to 350 gonna make or break a performance engine?

Know what I mean?

i have no idea what ur talking about but i ll just say ya....

By the way, I comend you for working on your 305 like that. I think thats great someone here has really taken the time and money and knowledge to do it all to their 305.

dont make it sound like doing it to the 305 is such a waste. If its done smart it shouldnt cost that much and the 305 should be pushing close to the 350. Only difference being 45 cubes that would make the power difference.

Now go time that sucka and lets see what she runs!
by all means.....go ahead tell us what she runs
