I just want to know what the best track time for my buddies car is with a good reaction time. It has a LO3 TBI V8 and a 700R4. The car has a K&N air filter, a flowmaster exhaust system, 3.73 gears and a posi, with stock 16 in wheels. Also i might mention the car has 145 thousand miles on it.

 

I'm gonna say mid 15's. By the way, just in case you don't know this, but reaction has no effect on 1/4 mile times at all. It only comes into play when bracket racing really.

 

High 15's.

 

yeah mid to high 15's depending on traction, driver, and tune.

 

mid to high 15's depending on the driver.

 

probably about a 15.7





mine right now is a 15.44 but that is going to take a dive bomb with a help from..........NNAAWWSS as the ricers say

 

most of u guys are sayin this car will go faster then the TPI 305 post in this forum. id say somewhere in the mid to high 16s

 

What post would you be talking about? A completely stock 305 TBI should be a very high 15 to a very low 16 second car completely stock. With his mods I would say about a mid to high 15 sounds about right. Many people don't realize this, but the peanut cammed tpi cars aren't that much faster than the tbi cars.

 

16.00 Not a bit faster. Buddy of mine with a Cat Back, and T5 w/ Centerforce clutch went 16.1 or 16.3 one of the two. Best out of 5 runs. Reaction time has nothing to do with your ET.

 

He didnt have 3.73 or posi either. Going from crappy non posi 2.73 to posi 3.73 can knock off quite a bit of time.

all the 3.73s are gonna do is cause traction problems and put that car out of its power band for the the traps at the end of the track.

 

tbi doesn't hit a wall in the upper rpm's like tpi does so I don't think it will take him out of his powerband.

https://www.thirdgen.org/techbb2/sho...vjo90RS8+gears

 

remember the Lo3 still has the peanut cam, that reduces the topend of the power band severly, also in the first thread u posted that is an L69 engine, the HO got a larger cam shaft. the 3.73s will make hte car quicker, but hed be a lot better off with a mid 3 gear ratios, like a 3.42, hed probably reduce more time with those. the 2nd thread u posted, that guy has a cam and other mods and also a 5spd. he can probably get away with the 3.73 ratio because he can shift into 5th if needed. the third one sounds like the same car in this thread here, i still would only use 3.42 gearing, but thats my opinion.

 

Here is a dyno graph from an L03 with stock peanut cam and swirl port heads. All he has is exhaust. Even with that crappy top end, tbi cars are still able to produce power in the upper rpm's. Notice how his power doesnt really drop off, even after 5,500 rpms. IMHO 3.73 gears are great for the L03.

https://www.thirdgen.org/techbb2/sho...ghlight=dynoed

 

ummm that dyno graph doesnt even go to 5500, and it starts to drop off right at 4800

 

178 rwhp @ 3900-4800 rpm pretty damn flat with 160+ HP FROM 3200 TO 5500 RPM (I wish the torque curve looked like this) and 271 rwtq @ 2800 rpm with 250+ tq from ~2000-3400 rpm. Air/fuel was in the 11:1 range most of the time(suprising, haven't check FP yet). This is all stock top end, stock/modified air filter housing w/ k&N, edelbrock headers, 3" cat, 3" hooker cat-back, and a streetmaster chip. This was quoted directly from the owner of the car.
Thanks

 

umm if u look at that graph it doesnt even go to 5500 and the curve takes a huge dive at 5200rpms. i dont care if the curves cross or not, thats great its flat, but its power band doesnt rev high enough to need or make use of a 3.73 ratio.

 

Okey dokey. Everyone is entitled to their opinions. If you feel that 3.73 is too much gear then try telling that to the countless tbi cars running them with good success. Camaroracer92 ran a 13.1 with his 305 tbi with completely stock internals and 3.73 gears and nitrous. The fact is tbi is able to take advantage of the gearing unlike tpi because it is able to pull further into the rpm's. You have tpi which doesnt like the gear, tbi does. Enough said. Why are you debating something you know nothing about? I would also like to add that the same person whos dyno graph that belongs to happened to run a 14.7 on completely stock internals using those 3.73 gears that you said were too steep.

 

the torque and hp always cross at 5252 i beleive. so what in the blue hell are you talking about. can we get atleast one intelligent post in this freaking thread before i have to bash somebodies ***** in.

 

Yes I realize this. I was simply trying to show the accuracy of the dyno in case someone didn't believe it. TPI produces gobs of torque and it makes all of it's power down low, usually below 4500 rpm, where as the design of tbi enables it to continue to produce power past 5,000 rpms enabling it to be able to take advantage of the 3.73 gears. Besides on a stock L03, you prolly will only be trapping about 85 mph anyways so you wont even be close to what the car pulls to with a 1:1 gear at the end of the traps, which is what you idealy want to achieve. In the end, when you mod the car the 3.73's will further take advantage of those mods.

 

it was 16.1, but i had major traction problems, with my poor suspension in pieces, and peg leg, i couldn't get better than a 2.55 60' that night, with a 2.2 60' that is into the 15's

if he doen't have problems, and can get some traction, he should be mid-high 15's

 

:sillylol:

 

15

:nono:

13

 

And your point is?

 

i'll take you up on that, 13's with TBI and a 305.

give me a couple more weeks to finish up cleaning the casting on the intake, and the final touches on porting my new heads

i guess a 13sec 305 TBI might make some of you IROC guys think twice eh, ohh yeah, the whole swap will have cost me less than TPI people spend on runners and intake base

 

yea 13 sec tbi on stock parts cept porting. i very honestly doubt that.

 

well, no it isn't on stock parts....

about the onlything left stock will be the shortblock, and computer.

 

exactly with a tpi u can run 13's stock in the right car. long as u got a good workin car and dont have the peanut cam.

 

well all i am doing is leveling the playing field.

i am using TPI heads, just porting them.

new cam, since the TBI cam gives new meaning to 'peanut'

getting a new intake manifold (why not a 4bbl intake manifold is dirt cheap)

how many 'stock' 305 TPI cars really run 13? even not peanut car cams, in stock form are probably mid 14's. you have to do the same things to them as you do to a TBI car. the minute you have to buy a hi-po part for the TPI car, like a new base, or runners, you budget goes way above what i am spending. AS&M runners are what $450 bucks? then $300 or more for a new base.

thats 750 bucks, that payed for my intake, my cam, my valve springs, and my rocker arms.

 

slp's car has exhaust/headers. all the "free mods" and he knows how to drive it. best time of 13.9 and best mph of 100. and those are all with 2.4 60 foots or higher. drop a 1.8 60foot and ur lookin at a low 13 sec car. stock weight and engine.

 

Hmmm, this is directly from his sig, "2.02/13.952 @ 97.08" Now that being said, he does not have the peanut cam and he also has much better flowing heads than the tbi cars have. Face it guys, the tbi is not limiting, it's the heads and cam that limits them. Once you do some bolt ons and get rid of the peanut cam and swirl port heads you have a car that will outperform any stock or mildly modified tpi car with the stock tbi unit. Hell there have been guys who were borderline 13's just by changing the heads and still using the peanut cam. Everyone always blames the tbi for the L03 lackluster performance because at first glance that appears to be the only difference between the 305 tpi and the 305 tbi, but it's a lot more than that. Once you remove the L03's poor top end you have a car that is capable of holding its own against almost anything on the street.

 

I'd like to see a near stock 305 car go 13's! WOO

My '85 IROC, with the better of the 305 cams, ran a best of 15.2. That's with exhaust manifolds, lots of bolt ons, rebuilt trans, low tire PSI and a 2.0 60ft!

The motor burned no oil *except the chevy salute* and got an average of 23mpg all around.

You tell me that my old car would run 13's.... and my 350 I've got right now only runs 14.0 YEEEEAH RIGHT

 

It's not gonna happen on a 305, let alone a 350 tpi. 13's stock, right

 

.

 

those r some of slps newer runs. right column on each slip. stock 305. take your 305 bashin to another forum. and if your only runnin 14's in your 350 and its a built 350. then maybe your obviously either havin horrible traction , you cnt drive, or you built a mismatched engine. and it sucks *****.

 

.

 

100 mph

 

Nobody said anything about a built engine. You said stock. Incase you didnt know stock means not modified, and stock no 305, let alone a 350 will run 13's stock in a third gen. Let me repeat that because you seem to think a 305 or 350 with a tpi will run 13's stock. Buddy, that aint happening. Sorry. Stock does not mean with headers, gears, tires, intake, etc. Stock means unmodified. What was the point of you posting your time slips. Ofcourse a modified engine such as the one that ran those times, can do that, but STOCK, which once again means not modified, will definitely not run anywhere close to that, peanut cam or not.

 

i really dont even want to get into this cause im tired of wasting my time trying to enlighten dis believers, but those slips are mine and these are the mods for the times, u dont believe good for u i dont really care

the 14.2 and 14.3 with no traction:

LT1 Cam
Descreened MAF Sensor
Ported Plenum
3.27 9 Bolt Rear
K&N Filters
Dynomax Headers
Dynomax Cat Back Exhaust
Cat Delete
Free Mods

last year, avg mph of 97, best et of 13.952 with a nice launch of 2.02

Ported Plenum
K&N Filters
Dynomax Headers
Dynomax Cat Back Exhaust
Free Mods

if ya dont beleive it, think its not stock enough or have any b/s to share dont bother replying, its my car i drove it to the 13.952 ur not gonna tell me other wise.

 

nick silver, custom x i think on this board ran a 12.9 on a basically stock 350tpi. all he had was slp runners and a higher stall convertor

 

and thats the end of that chapter

 

LMFAO, right man. You arent gonna run 12's with a converter and runners on an otherwise untouched 350 tpi. Once again, stock does not mean with a high stall converter and runnersl. Stock means with everything as it came from the factory. You don't seem to understand this.

 

So let me get this straight, that's stock? :lala:

 

most people i know of consider "stock" to be stock heads cam, pistons, rods etc.

headers, SLP runners, PROM work and a converter are some pretty minor mods to get into the 12s if u ask me, u can say its not show room stock all u want blah blah blah, actually when the car was show room stock it ran a 14.3 @ 98 he said. isnt 98mph a 13.9 pass? so that car was capable of thirteens now wasnt it.

 

pretty minor mods for the times man, i cut the lists down to the actual modifications, pretty short if u ask me

 

your such a ****ing moron. you need a slap upside the head. the dude did run that time with jus that for mods. why the **** would i lie? i dont even know the friggin guy. and i shoulda been more clear. stock motor. were talkin motors in here. so why dont u get your panties out of that big wad they are in. and go **** yourself.

and for built engine i said that to whoever was sayin they cant break 13's in their 350.

 

So a cam is now a stock motor? Ive heard it all now. Bolt ons are now stock as well, awesome. I guess a "stock" LS1 run's 11's huh? I don't believe anyone said their built 350 couldn't run 13's. I said a stock 350 tpi couldn't.

 

this is why i didnt even want to get into this, its a big pissing match

 

who said a cam is a stock engine? i think the point was is nicks car ran a 12.9 stock heads and cam, and my car ran a 13.9 stock heads and cam.

 

not you *****. the other dude. who said he cant break 13's in his 350. and it is not stock motor now. but he ran the 13.9 before he even touched the motor. and the gears thats stock. they r not aftermarket.. aside from the clucth and lt1 cam. every mod involves no parts or stock 3rd gen camaro parts. no aftermarket.

and u can say what u wish tryin to rain on dudes parade. but it wont work. your a dork with your head up your *** posting all over the forums thinkin you know it all, when you prob dont even have much if any dragstrip experience.
