You stand a good chance, in my opinion. He's stock, but lighter and though you're heavier, you have some work done. Good luck!

i don't know about all that...the 93 is more than likely an lt1...so thats like...275hp, 320?ft lbs
yours must be an l98...not sure what the numbers on that are....but i'm voting for the z...let us know how it goes

the Z28 should take you. 345#'s of torque(i think thats what the 93 LT1's were rated at) plus better upper RPM breathing, unless he roasts the tires off the line he'll take you

I would say If you had headers you would win but, your car just won't rev. as willing and the lt1 would take you but, he should be close still being you have some work done.

heh he's got you. lt1's are nice motors with an ultra wide torque curve. if you want to beat him a cam, gears and stall coverter would be the easiest surest way

Drakar

93 Z28 - LT1 275hp and 325 torque 3400-3500lbs + 2.73 or 3.23

90 GTA - L98 240hp and 340 torque 3400-3600lbs + catback and chip so corrected maybe 250hp + 3.23 gears


If he has the 2.73 gears then you might have a chance but if he has the 3.23 gears then he should have you by maybe 1/2 to 1 car.


Go race it should be very close, this would be more of a race of driver vs driver then car because they are very close.

You definitely have a chance!!! I raced a '95 Z stock with auto at the track and he ran a 14.42 to my 14.45. In a race that close, it's all reaction time. For the record, 93 LT1 Z HP 275 @ 5000 TQ 325 @ 2400, 90 L98 HP 240 @ 4400 TQ 345 @ 3200.

Numbers dont mean everything. Yes the LT1 has less torque, but it makes it a lot sooner, and has a broader torque curve. They also breathe a lot better than the L98, he should have you unless something is wrong with his car.

I'd say you have a good chance. My friend let me drive his 93Z (before he totaled it). It was a bone stock LTI 6 speed so he had the 3:42 gears. I was pretty impressed with it in the mid-upper rpm range but he was impressed with mine in the mid range and its a 305. The main difference is they have the top end power you don't. If its an auto though with stock 2:73 gears, I say go for it. Could come down to the better driver.

It has the ability to be close, but I beat my friend's '91 Z28 L98 by a 1/2 car length 0-80...and I can't shift

With headers you would still lose, and headers won't give you 30 horsepower. You may take him off the line, but he will pass you around 55-60 mph.

yup, maybe he'll hang till 70-75, but after that the LT1 SHOULD pull away...

If the Z-28 was in good cond. he'll beat you bad. I used to have a 94 Trans Am GT, A4 and 3.23 gears and dead stock it ran 14.2 all day. And the 2.73 gears aren't that different either. After my mods it ran very consistant 13.8-13.9 My mods K&N FIPK, Dynomax muffler,LT4 Knock module and air foil

Driver has a lot to do with it.
My last time to the local track I was staged next to a red LS1 Z28 which I assumed was stock and capable of roasting me. I had just pulled straight in for a time trial from my 20 mile trip from work. Outside temp was in the mid to high 80's at about 10 o'clock on a Thursday night. By the time we got staged, my engine temp was at about 220 degrees!! He had cooled and pushed his car through the lanes (6 speed) and must have been cooler.
Lights came down and I TREED him with my slow .740 reaction time to his dead 1.2 something RT. I expected him to pass me before the 60 foot mark, but to my surprise I stayed ahead. Farther down the track I could hear him coming behind me, grabbing gears & spinning his Drag radials hard. He finally caught me (blew by me like I was sitting still) right at the lights, but my side came on. I had won!!! & I had beaten an LS1 !!! I was on cloud nine.
We got our time slips, and I had ran a 9.44 @ 74.87 to his 9.10 at 83 + MPH. All 1/8th mile. So I had beaten him all through reaction time.
Turns out his car has an intercooled Vortech blower on it too. I don't understand why he didn't run alot faster than 9.10 @ 83, but I think traction may have made as much as .5 seconds diff for him. I'd think an LS1 should run 8.50's to 8.70's stock.
My friends 95 Z28 auto 3.23 runs 8.80's with only a moroso air intake, BBK 52 mm TB and drag radials. No other mods.
Anyway, point is: A. Don't sleep at the line - even my .740 RT was pitiful, his was just way worse. B. Don't spin your tires & take some time to practice launching. See just how hard you can leave without spinning, or barely turning a tire.
That may be all the advantage you need.
Good luck,
Jason

headers and a good cat back have been proven to give upwards or 30 hp, because these cars have such restrictive exhaust. I say, you get headers, and its an auto, and it will be VERY close. I took a lt1 with long tubes, borla cat back and free mods from a roll, although ive heard that his car isnt running that great with those long tubes..... but hey a kill is a kill.

I know this is gonna sound like im stupid but what is a free mod.

SOLID LIFTER

Wow!This is an old topic!
A "free mod" is a modification thats done to your car for FREE, like gutting your air box, gutting your cat, or gutting your interior or any other dead weight.

Yea I've beaten a lot of faster cars just cause they are like retarded off the line or something. .3 seconds in R/T can make up for a 14.4 @ 96mph car beating a 14.1 @ 99mph car. Its great, I pulled a .557 light at the track to my buddies 1 second + R/T. Needless to say the 305 TPI with just exhaust roasted a 97 Cobra, not to mention his 2.3 60ft didnt help him (mine was 2.2). I put about 4 or 5 cars on him at the end, *** he never heard the end of it, people i didnt even know where laughing at him hehe.
