hey just wondering what the 1/4 mile time for a stock '85 vette would be, we got a guy over in the honda forum who wants to race one with a 98 integra gs-r and we're trying to explain to him that he will get beat badly by the vette but we aren't sure of the times. so if anyone has the numbers it would help. thanx.

85 vette has the cross fire injected engine. it should run mid to low 15s.

mid to low 15's???? are you kidding me? holy shit and all this time i thought vettes were fast?
i would assume that newer ones are alot quicker right? but i didn't think the older ones were that slow. well not that that is incredibly slow thats around what my car can do (low 15's-to very high 14's) but i always thought vettes were like above and beyond you know?

Nothing was fast in the '80s. C4's and C5's are just a shade faster than the Camaros/Firebirds of the same years...

In 86 they started using the tpi motor which got it down in the 14s. but yeah 80s cars where slow.

85 was the first year for TPI , NOT 86 (86 was the 1st year for aluminum heads though, halfway through the model year). I had an 85 vette a couple years ago. Stock, it ran in the high 14's, with some mods (gutted cat, exhaust, chip, AFPR, ported plenium, airfoil, airbox , K&N)it was in the low 14's (the best was a 14.3) . The C4 vettes do hook up real good off the line, at least mine did.

most of you guys are on crack,

TPI started in 85, crossfire was 82 and 84, with a good driver and good tires an 85 will turn a 14.0 flat. If you cant pull at least a low 14 time you need to go to driving class, stock for stock the integra will get his ass handed to him

I guess where you live the weather conditions are always great and theres no humidty. The track you're at you can always hook up perfectly? Try running your car when its 80 or 90 out, then go back when its 60 out, there'll be a bit of a difference in times. TPI & LT1 engines go to sh1t once the humidity & temperature get too high.

closest track is englishtown, and your correct about humidity and other factors, the 14.0 was on a non humid day at about 70 degrees

but (out of the topic) the lamborghini countache in the 80's can still kill a new stock vette :P

A Countach would probably be even with a C5, but would probably get beat by a Z06 , ZR1 or LT4 C4.A Countach isn't really made for the 1/4 mile anyways.

I have a 1985 Corvette. Is is a bone stock automatic with 150,00 miles. I ran 14.29 - 14.35 @ 95 with high humidity and over 100 degrees at the Texas Motorplex (2.10 60ft).

I also have 13 roadtests of 1985 Corvettes that range from 14.1 @ 97 to a 15.0 @ 91 mph. The average for all of these tests is 14.5 @ 95 mph.

Some people have been able to get a 13.9 out of a stock '85 vette 4 speed. These cars were very quick for their time period.

( Average 0-60 5.87 seconds )

The 80's sucked as far as sports cars go. All these new fuel crisis and all this emissions bhonkey was just starting to take the full toll on the automotive industry. Both in a sense I think the 80s were one reason cars are so competitive now. Any time before the 80s what were the reasons for thinking in the US. Bigger motor, more gas, more power. The 80s forced the automotive industry to produce more efficient engines. And in effect you have new C5s with same cub size, only pushing twice as much power at better gas milage. I belive the CFI motor was cranking 175hp 250tq (at least in the F-bodies). Compared to the 350hp C5 running mid to low 13s. So i gotta thank the 80s for being sh*tty. Just my thought on the whole conspiracy hehe.

My 85 4 speed has a few mods and it runs a mid to high 13 with street tires. the integra will get torn to pieces.

I have owned both 85 & 86 Vette's and anyone who say's they arn't fast should drive one, I handed almost every car I raced there ass and as with most GM engine's the Horsepower on these car's was underated, At englishtown, NJ . I ran a 14.1 with my bone stock 85 Vette

1985 had L98 motor which put down 200 hp and 300 lbs torque at the wheels. with a few simple mods you can make this go thru the roof. long tube headers alone add 25 rwhp and about 13 lbs of torque. The L98 was a very choked up engine that just needs some love to open it up. A great set of mods for a L98 for under 2k is Accel super ram intake, Hooker long tube headers, K&N air filter cut the air filter lid, Adj. Fuel pressure regulator, A chip from hypertech or what ever brand you prefer, and some 1.6 roller rockers with new springs. This should put you into the low 13s maybe even high 12s no problem.


Then you can roll up on C5s and ask how much they spent on their car as you beat their ass laughing the whole way.


Oh yeah that integra doesn't stand a chance.

actually the stock cfi motor had 205 hp with 265 tq but a simple manifold change can boost it to 260 hp alone. my cfi motor puts out about 400 hp off the back tires, but the block is the only origional motor part I still use.

cfi?? I'm talking about tpi that was in most c4s.

The TPI in 85 Vette was 230 nhp (net hp) @ 4400 rpm and 330 lb/ft of torque @ 3200 rpm if i remembe correctly. My grandpa's 85 was stolen in Youngstown somewhere around 86-87. So he got an 87, which is SUPPOSEDLY slower than the 85, even with 240 hp and 345 lb/ft of torque. He had it up to *an indicated* 140 over on u.s. 6 between pymatuning valley and andover, over by the lake there..(if any of you are from northeastern ohio)

Wow this is one old thread, I'm assuming no one told you about not posting in threads more than a couple weeks old.

my stock 85 with 3.07 gears went 13.7 with long tubes and dual ex. I then went 11.91 with a 150 shot.

Now it's mildly carbed ( still has 460 lift cam) and just went 12.76 on motor and 10.98 on the 150 shot. :iceslolan
