1990 IROC-Z vs 1987 IROC-Z (G92)

Hey Fellaz-

I've managed to get myself into another race with a local kid in town, although this one might be even more interestin' than my race with the Mustang! (Actually, it's hard to get more interesting than a race with a girl who wants to mess around afterwards )

Anyway... this guy actually knows a friend of mine, and I happened to meet him and his car last night while over at my buddies house. He's got a somewhat beat up, but strong running '87 IROC-Z 305 w/ a T5 manual (G92 option) and some small mods. He is constantly revving and dumping the clutch in his car, so I know it's got alot of wear 'n tear...

For your referance, I am going to post his setup and mine:

-----------
1987 IROC-Z Camaro (G92)
Tranny: T5 Manual
Engine: LB9 305 TPI
G92 Pkg: Deleted A/C, 4-wheel disc brakes, 3.45 gears
Mods: Gutted catback, gutted air box, gutted MAF, flowmaster exhaust.
Problem spots: T5/clutch is worn, EGR vaccum leak, balding tires.
-----------
1990 IROC-Z Camaro
Tranny: 700R4 Automatic
Engine: LB9 305 TPI
Mods: Ceramic coated headers, gutted air box, K&N air filters, TPiS air foil, high flow catback, flowmaster exhaust, brand new z-rated tires.
Problem spots: N/A
-----------

Based on our two setups, who do you think will win this race?

I'll add that we are both planning to install performance chips in our cars as well (he's going with a Hypertech, and I'm going with JET Stage II). But chances are, we won't have them before the race takes place...

Man I think it will be close. But if his car indeed is kinda crappy but is running strong I think he might bearly have you by half a car or so.

I'll say him. You've got 210HP and 285TQ and he's got 215HP and 295TQ, AND G92. He's has a much better gear ratio. U are buying the better chip though.

What I mean is, his car is beat up... I always hear about him doing donuts, revving to 6500 RPMs, doing burnouts etc... but nothing has gone out yet and it's running good for all the abuse it has taken through him...

My car is well tuned and with 93,000 miles on it. I am not sure exactly how many miles he has on it, but I know it's over 100,000 without any rebuilds.

You're going off of our stock setups... we both have our share of mods that up our horses and torque power, look at the stats I posted on our cars in my first post...

You are correct about him having a better gear ratio, he's got 3.45s, but I don't know if that will save him...

I'm still going to say he will win, and if he can shift....

It will probably be somewhat of a close race. But, if your car is in better condition mechanically, it could be different, if his car was running as good as yours I'd definetly say he would win. If u do win, tell him to start treating it right and maybe it would be at full its potential. The only mod u have that is an advantage is the headers, but he's got 3.45's and a 5-Speed. (like I said if he can shift) Those G92 cars are fast.

I'll say you'll win just because you have SLP Headers and afew more mods. I think that your mods will make-up for the 5HP and 10TQ he has on you. Just make sure you get a good launch; with the new tires you should have better traction.

You are going to smoke this guy! Are you kidding me?! I have an 88' Iroc w/350 tpi, and I gained 4 tenths alone with $100 AutoZone headers!! Plus you have a 700R4 and he has a T-5. The fastest shifter in the world still can't outshift an auto tranny. Just my thoughts. Good luck.

Of course your going to see more of a gain, u have 45 more ci. than a 305. Especially if u put the headers on after u had the cam and heads, or either 1.

Guys, these are both 305's...There is no 350 involved...If he hooks up and has no real problems, you lose...One problem though, as in him not launching right, him not shifting right, or his car being in poor mechanical shape, you win.

its gonna be close. you having the headers may give you the advantage. but he does have gears like they have said. i have an 87 with everything he has plus headers and i ran a 14.2x at 96 and i have 3.08 gears. i think i would run 14.6 without headers maybe a tad slower if that gives you a good estimation point. i picked up about 8 tenths with my headers because i could get a better launch and had more power. (didn't bog off the line anymore)

Some valid points have been made in this thread, as both of our cars have advantages and disadvantages.... I know either way it will be a damn close race, which is why I needed to hear some opinions from you guys!

I think the only real disadvantage I have is my rear end being a posi 3.08 gear as opposed to his posi 3.45 gear...

The only real modifications he has done to his car is freeing up some air flow by gutting the catback, airbox and MAF... and that doesn't add up to a whole lot of gain... remember, he started out with 215hp w/ 295tq. Add to the fact he's pushing over 100,000 miles on his transmission + engine without any rebuilds... and is constantly running it hard. He's not exactly in tip-top shape...

I'm pretty confident I can take him with the condition and setup of my car, but there is only 1 way to know for sure.... and I intend to find out

Yeah... but I'm guessing you don't rag on your Camaro everytime you drive it...

well i get me some good 2nd gear spins quite often and i powershift when i drag race at the track.
sports cars are made to be beaten on. if you can't run a car hard every now and then its not worth having.

ONE2FLY I noticed you talking about a engine swap and another board. Dont get discourged with your car. Its still quick. And look at Smokin87's times. Let him be an inpseration

Yeah dude I saw that post. In fact, I replied to that post!!

For what u want I think what u currently have is good. U want a good street car that can runs good times (I'll guess u mean high 13's-low14's) and your car is definetly good for that. If u wanted a 11-12 sec. car the choice would no doubt be the 350.
