Default 99 ss vs 01 z28

well i normally dont street race but every now and then i get the urge to do so. well last night i race a buddy of mine with an ss and needless to say i was a bit dissapointed with my cars performance.

the cars:

99 ss m6: pretty much stock but for a smooth below and an upgraded fuel pump.

01 z28 a4:LT headers, ory, flowmasters,lid, and a cut out(it was closed tho)

we raced twice from a dead stop, the first time he had me by 2-3 cars...i sorta freaked out a bit when i punched it and my rpms went up to 5000. ive never had them up that hight before, so i let off the gas a bit.

the second time it was more of an even race till the end when he put maybe a car on me.

i thought that i would at least beat a 99 ss with my mods and all but i guess i was wrong...

ill be racing him again once i get it dyno tuned in couple of months....at least an ls1 game me my first lost.

Just curious, but 2.73 gears or 3.23's? And might have some better luck if you leave around 1000-1500ish instead of just punching it.

That doesnt sound right to me. You should of took him. I would also like to know what gears? I have beat z28's with same mods as you before too and i dont have LT's.
Maybe he was just a better driver.

i think i have 3.23..but ill have to double check the code on that one...in the take off i had him about 1/2 a car till he hit 3rd gear and it was over for me.....

green 28 , when you say leaving at about 1000-1500, do you mean put my car in N and rev up to those rpms and finally **** to D??? i dont race that often...so im clueless

If you press the brake all the way in and slowly depress the gass pedal, the rpms will rise slowly until it gets to the stall. The stock stall on my v6 was 2400. The rpms will just hang there until you floor it. It's kinda hard to explain, maybe someone else can do a better job...

DO NOT NEUTRAL DROP THE CAR.

Leave it in D, stay on brake with left foot, rev with right foot till it hits stall rpm.

When you go, release brake and stab gas at same time.

The other way I launch an auto is just stay on brake, stab throttle at go, but don't floor it till traction is certain.

An auto should take a m6 off the line most of the time when stock. Modded, it's anyones guess depending on the types of mods done to the car.

M6's will rape an auto from a roll though with similar power levels.

My SS is mostly stock except for a handheld tuner and a couple air induction things...I kept right up with my brother's 03 Cobra until about 4500 RPMS in 4th gear.

thats wierd you lost when i had full bolt ons i never lost to a near stock m6. but like said above you do not want to punch it in the a4 just stab and work your up to WOT as soon as traction permits. also with the LTs did you have it tuned? if not get it tuned and try again.

You're also not using as much of your RPM range as you could. Shift that thing at 6 grand. It'll pick up a lot. LS1's are beasts from 4500-6000.

Not to sure how true this is. I raced a m6 with same mods as my car from a 35 roll and he beat me by about half a car every time. However, he might not be the best shifter ever. Also, you should have beat this guy by at least a couple cars. I would get the car tuned and try again. A lot of guys say there cars weren't performing properly until they got it tuned. Never had that problem with mine it was tuned the next day. Anyways, my two cents. Good luck nest time.

Ya stop being a puss and keep it floored when you get up to the 5000 mark... Just kidding but seriously you need to just keep the thing wide open let it run up
to the 5800-6000 mark..

You'll know because your car wont be able to hold those rpms, you'll start to take off. Your stall converter is sort of a wind-up for the engine for lack of better description, when you reach top stall speed, which on my stock A4 is only around 1400 i wanna say, the car starts to pull forward, it can no longer wind that fast. With an aftermarket stall converter like a 3600, it lets you hold the footbrake and your cars rpms will go to about 3600 before it starts to pull. hope this helps

As an auto, never let off just keep the thing floored and let it shift when it wants to, 5k is not enough, let the thing rev out!
