just wondering what you guys think will win. his car pulls hard when he gets into boost , but im sure i can rape him off the line. its going to be at a 1/4 mile strip too

stock for stock a mk3 turbo and a l98 are almost dead even. Just by looking at the mods, I would think you have the edge, unless the boost controller and intercooler are giving him a lot more power than i am guessing they are. Regardless, i think it'll be close.

I can tell you from my experience, the throttle body spacer doesnt help you at all....it will hurt you actually. I had one on my 383 and took it out i gained ab 10 rwhp and 10 rwtq....take it off and hopefully you have ur stock TB bolts... but i think it will be close....

chevy boi

i got it for free with the runners and the injectors. i thought i felt a difference with it on but i might have not. any guess what ill run?

5678TA

do you really need the 100 octane gas?? some have said that race gas slows them down.. and good luck launching those kumho 711's.. my stock s-10 cant even get traction with those.. then again, i think i got an old set and it has been another 4 years since i got them..


on the bottle you should rape him.. plain and simple.. N/A should be interesting..

I don't see you getting traction worth a crap and those kuhmo tires really aren't drag tires. Also you have a bunch of timing for a 125 shot, and the 100 octane race gas always made my TPI car run like total crap. I would say set your timing back to 6 degrees, skip out on the race gas, and hope those tires grab you'll be more than gold on this one. If I were calling the race on the way things sit right now i would say it will be close or he'll edge you out.

chevy boi

well im still tuneing the car for the nitrous. i was useing 100 oct so i whouldnt get dentation with the nitrous. and the guys in the power adder board said about 2* per 50hp on the nitrous so i didnt think go 10 wasnt to bad of a idea. the track we are going to uses VHT track Bite which i was hopeing will help out with the traction worse comes to worse i have a friend that will let me borrow his M/T ET streets

beside traction anything else i should worry about?

89formula350b2l

iTrader: (11)

worry that he doesnt have any other mods...
and yes i agree NA it will be close but on the bottle....Game Over man!

86firebird350

i think they meant 2* retarded for every 50hp of nitrous.

Is a Mk3 a last version rounded one? Those are heavy pigs! Could be close IMO. I had no issues with a boxy turbo model from 55mph start on the hwy once. The guy sh*t a brick and followed me to find out what I had done. He was embarresed to find it had no power adder. =)

chevy boi

no the mk3 is a late 80s early 90s one. the one im racing is a 91. so should i run the timeing at 4-6 dgrees and just fill it up with 91?

o and i was talking to him today and he sliped out that hes increaseing the boost to 14psi so now im gonna use the 150 shot jets.

Orr89RocZ

iTrader: (20)

i'd keep timing at 8 degrees and use 91 oct for n/a

on the bottle i'd keep timing at 4-5 degrees

1991CamaroRslow

iTrader: (3)

Make sure the EST is disconnected and set your base angle timing to 4 degrees. Run NGK TR6 plugs with a .035 gap and jet up to the 150 shot. If you decide to run the 100 octane just mix a little bit of it with the 91 octane gas. The timing you have now is REALLY high for any ammount of spray. Stock you can go to about a 125 shot, after that I recommend taking out 2 degrees and 2 degrees for every additional 50 hp worth. So you would have 2 degrees out (4 degrees, 6 is stock) for a 150 shot and 2 degrees for a 200 shot, 0 for a 250 shot; and that should be about the limit for what you're doing now.

chevy boi

kool so i knocked the timming to 6* and i got me so freash plugs and installing them today. is there anything else i can do to the car to get a little more out of it?

Toyota h8r

Im going to be the first and say the supra will either be door to door or be a tick faster with the camaro running spray. the reason i say this is ive owned three of the mk3 supras, and with the work that car has done....they fly! I hate talking bad about camaros on a camaro site but ive been there.... done that.Ill never go back to them pos cars though, between the headgaskets blowing and transmissions blowing.....they were a nightmare.....not to mention wiring....nightmare in itsself.

So only way your gonna get em is your car has to be tip top and have a ton of traction as the supras i had were horrible from a launch.

All i can say is dont get to cocky and just race him.....

chevy boi

im not cocky about this race at all, im acctully worried about it. and yea i helped him do his head gasket. and i know first hand how hard it pulls when it gets into boost. i was just wondering how my camaro will hold up aganist it

1991CamaroRslow

iTrader: (3)

ET Street radials and launch on the spray! You'll be so far out ahead in the first 300 feet you should be set for the rest of the 1/4.

chevy boi

ok so i got my buddys M/T and the track we are going to uses VHT so traction shouldnt be a problem. normally i just spray 2nd gear so if i spray off the line will i be able to keep traction. i know i can damm near launch at WOT with the tires im getting, but i never launched it on the bottle

Mikz86TA

iTrader: (4)

Oh. Then that is the same model/body style I ran. No problems

1991CamaroRslow

iTrader: (3)

With MT ET Streets or ET Street Radials you should be able to spray pretty much dead out of the hole and hook hard. If they're basic MT ET Streets air them down to about 14psi, if they're ET radials try 18 to 20psi in them.

rockit

iTrader: (3)

i worked at a dragstrip and spraying off the line with vht(which we used) is like saying you want a jigsaw puzzle instead of a transmision. i'd save the spray for second, 60 ft is our domain anyways. less you're built to take the spray your stock 20 yr old stuff won't hold up to a 50 percent increase in power plus the traction increase those tires would give you.. all that power is supposed to get you going but it goes through some very destructible parts before it gets to the ground.. i'd rather lose a race then lose my trans, it's embarresing, it pisses off the track crew(i've cleaned up quite a few blown diff's, driveshafts, i even have a peice of sluminum connecting rod i found after a chrysler blew, grrrr) and makes everyone else run slower from the lub you just blew all over the 60 ft mark. not to mention you'll kick yourself as you install your new, expensive parts. i'm not trying to be cocky about this, just telling you what i saw in three seasons of running the starting line/burnout box 5 nights a week. launching on the juice is haaaard.

i just had a thought,how can they rate nitrous for an hp amount? i can see a torque amount but as hp is rpm related, wont x amount of spray be worth differing amounts of hp at various rpms??

freestylzz

I've never seen an MK3 that impressed me performance wise.

Sure I think they look nice, but I bet his car is all show and no go.

I'd run him in a stock L98 for that matter.

rockit

iTrader: (3)

i have a slip at home, from last week. mk3 murdered me, he ran a 13.3 but his intercooler was the size of a coffee table. i liked the car, flat black, plain rims, no tint nothing, just a mean *** ugly street car.

Toyota h8r

The mods listed tell me that car will fly, i know first hand that very cheap upgrades and they scoot.....hence my screen name though "toyota h8r", they are fast as hell, but get unreliable with more hp....unless you have a ton of money and do it right. Ive seen mk3's lay down 800hp and run fast.....but at how much $$$$$?

Dollar for dollar a f-body will walk a mk3

1991CamaroRslow

iTrader: (3)

You're never going to get the full benefit from your car unless you're blasting that guy in first. If the track has VHT and you hook well that's great, don't be stuid and spray immediatly when you jump on the gas but don't wait until second if you're sitting on ET Streets. I've sprayed my stock unreal milleage car through 3 stock 700r4's and none of them exploded on the line they DID however wear out quick (at least I suppose they were all used). I finally built a TH350 for the thing. I will warn you to keep an eye on that rear end, I did have my welded rear drop the spider gears while cruising but that was mostly because we weakened them with the welding. The warning from rocit IS valid, be logical with the spray and if you're on street tires wait until second, if you get the ET streets I'de spary as soon as the motor isn't lugging anymore which on a TPI car isn't long at all, just keep the jetting low and everything should hold for a good while.

Always2Slow

Sounds like a drivers race to me and whose gonna get traction or not. If he can keep that supra up on its power band, you better hope your 60ft is pretty good. If their is vht down you should hook fine. Id spray in first after 3 grand.

chevy boi

update

well he ran into some fuel cut problem and is going to be knocking the boost to 8 psi. but due to this my friend needs his MT's back so hes out 6 psi and im out my DR. it should be going down this wesday so ill post when its done

89formula350b2l

id beg for those MT's!!

So who won?

chevy boi

we never got to race. he had to focus on his classes and the race kinda went on the back burner. on the up side tho i did get to track my car and was running 13.5-13.0 almost all night. i am in despreat need on some tires

travishenry

youll eat it for lunch. Cuz its a camaro

rockit

iTrader: (3)

haha yep, some thirdgen camaro's came with a limited edition blessing by the pope that means they never lose. this couldn't be had with a manual trans or t-tops which were considered "un holy".

84RIceEater

the last version one... slow and heavy pigs huh....

1JZ-GTE Twin Turbo I6
280 hp 272 ft·lbf limted by the gentalmans act.

runs 13.1 @109mph.

japans version

320hp 315TQ

thier noted as one of japans supercars and considered and undestroyable motor in many minds

chevy boi

strong motor yes. indestructible no. 3 of my friends own mk3s one of them has 3 to himself. and ALL OF THEM blew there head gaskets. 1 of them spun a bearing while under 27 psi ( he was racing a supercharged chevelle). not to mention all the little bs wiring and the expensive parts they use. of course these are 7m motors. i havent ran into a mk3 with a 1j in it yet but hell ill race it for ***** and grins

84RIceEater

naw i dont know that much about 7m motors, but i would i was refering to the 1j

25thmustang

I think the indestructable thing is in reference to the bottom end of them. I also don't know about the 7m, but the 2jz motors are strong as ****. A stock bottom end that can support 1000 hp, now thats insane. I also think in this race scenario, 10 psi is laughable. Even 14 is, my guess is he will run more boost than that for the race. With a boost controller, why not just turn the wick up to win?

freestylzz

My younger brother has a 2000 Toyota Tacoma 5 speed which he tranplanted a 1JZ (twin turbo) motor and wiring harness in it. It's no laughing matter.

chevy boi

well i know he cant because he has horrible fuel cut problems. he was running into this at 14.5 psi and dosent want risk going lean by buying a fuel cut defender.

rockit

iTrader: (3)

wait the mk3 is the round one? yea the engine has potential but they ARE heavy by jap standards, all their super cars are, the 3000gt MR, the r34 GTR and the supra they're all 3 liter cars (except the gtr it' only a 2.6) but they weigh like our cars do. they are on par with our cars weight wise but way ahead in technology and behind in literage. however 330 hp out of a stock 2.6 liter is damn sexy, skyline's just have that skyline sound too.

goes to show how crappy our head technology is, 2 valves just don't cut it these days. the skyline's torque curve puts tpi to shame as well, with peak torque being reached in roughly the first 20% of the rev range. The ls1 is a joke next to an RB26.

chevy boi

nope the mk3 isn't the jelly bean looking one. its the one that kinda looks like a ford probe.

25thmustang

The MKIV's are one of the sexiest cars ever made. When done right, with the right stance, wheels, tires, paint etc... they look down right gorgeous!

5678TA

that usually goes for every car

5678TA

i'm pretty sure chevrolet is getting it done with 2 valves per cylinder.. 505hp N/A in a production car.. people have gone 8's N/A with 2 valves per cylinder.. also, the ls1 has gone 8's N/A.. i doubt it is a joke next to an rb26.. what american cars lack in technology, is made up with displacement.. now days, it doesnt matter how many cylinders you have, how much displacement, etc.. if you show up to the race, what you have is fair game..

84RIceEater

rockit

iTrader: (3)

they do with 2.6 liters what chevy does with 6, who hoo for chevy.

do you want me to bring up the skyline's specs?? how bout a z tune or s tune compared to a z06? I'll compare an out of production 2000 ish skyline with a 2008 corvette any day of the week.

yea two valves can be awesome, but on the street, where gas mileage, and the ease of moddability, and the flexibility of an engine to get you around day to day and get you to the win on the spur of a moment, that's where new age heads are nice.. you know?

Skyline weighs as much as an f body, has more accelerating traction then a vette or an evo, has a better torque/powercurve then any of those listed above, it's bane is front tire wear and understeer, and i'd bet it's still better in those respects then an overwhelming percentage of world sports cars.

kairles

iTrader: (2)

wow you must read alot. sorry but a skyline is not all that. how is the skyline or any other "supercar" ahead in technology? and as far as torque curves go, its a turbo car.

InfernalVortex

iTrader: (4)

Before you start knocking high displacement pushrod V8s...

We dont have to waste crankshaft energy turning 3 too many cams, so we have a lot less drag on the motor and we actually get much better gas mileage per hp. It's called Brake Specific Fuel Consumption.

These super-tuned Ferrari V8s get worse mileage than LS1s and they're half the displacement. It's weird to think about a pushrod V8 getting good gas mileage, but in the big picture, it aint half bad...

Toyota h8r

Okay run a 08 Z06 vs a r34 skyline stock for stock and tell me who wins......

also, i have owned 3 different mk3 supras,
(2) 7mgte(3.0L turbo) , (1) 1jzgte(2.5L turbo)
They can be fast but dollar for dollar spent my 85 trans am has been faster.

My 89 targa 1jzgte(yes it was a swap as the true 2.5T cars are not legal in us)





My hardtop 87 7mgte car(motor was out in this picture)




My hardtop 86.5 7mgte

84RIceEater

run in what? stright line, road corurse? from a roll? also its a 8 year difference... look at the new model skyline... faster(in every thing) than a z06 and cheaper..

406z

On topic: Here is what I got from wiki "The 7M-GTE MA71 is capable of propelling itself 0-60 mph in 6.2 seconds with a dismal 6.8 psi of boost. It reached the 1/4 mile in 14.7 seconds at a speed of 95 mph (153 km/h). Its top speed is 156 mph (251 km/h). Due to an extremely restrictive exhaust, the 7M responds very well to exhaust modifications"

It's a drivers race(period). If he is having tuning problems, you may walk him if he cannot work out his fuel and boost issues.
*********************
First, the GTR is not exactly a great deal cheaper. It is competitivly priced at 70k.

Second, yes it does run seven seconds faster than the time posted by an 05 zo6 around the ring, but....that is an 05!

Third, other than super tuner versions or etc, the GTR has laid its gauntlet down. It's accepted that what we have seen out of the GTR is what we will get.

The last two points are key. Yes the GTR is fast, but what about that 09 corvette?

We know the base model is receiving an exhaust upgrade this model year, but the z06 will remain unchanged.

Even more importantly what about any 2009 high performance model?

GM like usual is holding their cards close and hedging their bets. Nissan has ran its press, but all we have on the newer corvette zr1 is http://jalopnik.com/cars/detroit-aut...ble-326717.php .

So we have an engine pic with a guess at specifications, and a video. One can also find the laguna seca video, but it is just as ambiguos.

There are a thousand rumors as to what exactly the zo6 or zr1 will be like. Soem say they will use magnetic shock technology like Ferarri. The bottom line is no one, but the makers of the zr1 and new z06 know how it will perform. If the new corvette is going to kill hyper cars than I have no fear of a petty 350zish skyline.
