Took the Camaro to the local 1/8th

[Chrisco]

Well, I was talked into taking my Camaro to the local track with a couple of friends the other weekend. Let me tell you, as much fun as 4.10 gears are in that car, they kind of suck. The reason being is that I'm petrified to put any kind of real tire on the back of the thing to get it to hook in fear of grenading the diff. And... because of this, I get no traction in first and most of second, and even a bit of a loss in third with my crappy street tires. Overall, it's still a great fun car on the road, but the track numbers don't really do it justice for its capability. A set of tires and a good launch would yeild MUCH quicker times. Enough of the bs!!

60ft ... 2.248 (spin spin spin even with alot of clutch slippage and a 2500rpm launch)
330ft ... 6.020
594ft ... 8.489
1/8 ET ... 9.03
1/8 MPH ... 83.05

Oh well. The best part was that there was a 04+ Ford F-250 with a Powerstroke cutting 1.8 60fts and running mid 8's at about 85mph. That thing was nuts.

did ya drop the tire pressure to like 15-20psi ?

on my best 1/4 run, i did

2.230 - 60'
5.924 - 330'
8.877@85.47 - 1/8

wow congrats.

is it a stick car? if so you dont have to dump the clutch and shock the shit out of the tires, leave the line high at like 5grand and slide the clutch not tooo fast but not tooo slow to where you're burning the shit out of it. the car has a 1.8X in it on an allseason once you get the hang of it.

5 grand is way too high to launch from. Slipping it just right from 2500-3k still yielded way too much spin in the tire. Attempting to slip it any more and the 60ft would drop slightly but the ET also dropped by about 2 tenths.

Not with semi-worn 245's and a 4.10 rear end gear spinning them. Trust me.

Yep tires were dropped to 20psi. The thing is a monster and is definately quicker than what the times show... I just couldn't get the rear to hook to save my life. Even with a decent amount of clutch slippage through first it'd spin all the way through, then hit 2nd and spin half way, then hit third and spin a little more.

I do have to mention that I absolutely love the overall gearing vs 1/8th mile. I cross the line and immediately hit the rev limit in third @ ~83.5mph

if they are true street tires 20psi will 60ft worse than if you left them at normal driving pressure. only a drag radial or slick would work better with lower PSI. street tires will cup and the center of the tread wont be touching the ground with low pressure in them, making your contact patch smaller. I have ran my SS on a stock 17" rim with a true street tire and the best 60fts are at 30-32psi.

Thanks for the tip! If I ever take it back to a track I'll keep that in mind.

uhhh.....no its not.

[Bad00SS]

it depends on where the power band is. with the camshaft i have in my car if you launched under 4,000rpm the car will 60ft like shit. on a stock rims with a street tire it's tricky but I just slip the clutch and ride it out so there is minimal wheel spin. on an ET street I launch at 6,000rpm

Is it true that it's pretty pointless to 'warm up' a street tire?

I never do. if it gets real hot oils can come out of the tire and it will be more slippery than sticky. IMO the only tires that need heat to work are tires with race compounds. road race tires, drag radials, slicks, ect. on my 17" street tires I allways do a quick clutch dump and spin the tires for a couple feet to clean rocks off at the track. but no real burnout is necessary.

Spot on with all the above info. The most you need to do with a street tire (regular street tire, not a drag radial) is a quick spin to rough off the debris. Any more than that and you're only going to hurt yourself.

umm. i would launch my car with slicks on a stock rearend at 4 grand and it never had a problem. now if you want to be safer you can buy my rearend. strange 12 bolt 4.11 gear spool no abs, 500 miles on it. 1800 and its yours. rearend was NEVER raced

I would agree, however every time I've been to the track in my caprice, If I don't do a burnout, I spin like crazy, and the only way I can get a good hook is to warm em up. And I have really shitty all seasons.

I'm fwd and I spin no matter what I do to the tires.

My buddys 95 talon turbo FWD had BFG drag radials on it and they worked great at the track. a good limited slip differential would help alot though.

a 5.0 makes peak at like 5...stock on a tire with a gear i launched mine at 5k. remember it hooks, shocks the tires then brings the rpm down to 3500 which is peak torque. i dont know ls1's but they make power at what maybe 5600?

i got me a nice c4 now so no more stupid banger b/s.

When I said street tires i meant STREET tires. ie: brigestone potenzas lol. Not mickey thomspons or bfgs.

If I were to try to launch from anywhere near that high, slippling the clutch until it catches fire wouldn't help.

power as in HP? stock camshaft in a ls1 it'll make peak HP around 5,600rpm yes. my car makes peak HP at 7,000 RPM with my cam.
