Launching, high horsepower, a few questions...?

I am planning on making my debut track appearance in a few weeks with my 1996 Camaro Z28. It is making 752rwhp/626rwtq. The car has a T-56, aluminum driveshaft, and Moser 9", with Moser 31 spline axles, etc...blah.

I plan on running both ET Streets and Nitto 555Rs.

I was wondering what some of you guys with higher horsepower cars are launching at. Granted, 99% of the things I ask about I end up just having to find out for myself but...I'd just like a little heads up.

I'm not sure if I should just go out, do a good burnout and drop the bomb on it at like 5000rpm, or slip the clutch and roll out on it like I do on the street.

You guys think it will stay together with a hard launch?

Ditch the ET Streets and Get Hoosiers. Pick you launch RPM and dail in the chassis to hold it. ;) DO NOT slip it out of the hole with your power. The clutch will not repeat to often ;)

With that much HP and good soild take off's I am going to give the DS the first break. Once that is replaced by a Denny's DS you will get a few passes then ripp the Out put shaft in half. Now at this point you will either ditch the T56 and go with a TH400 or upgrade the output shaft to a Viper setup.

You have some good numbers there!

Good luck!

No preference on the tires, but I agree that the driveshaft will not hold up if the car hooks. The T56 held up to 733rwhp in my car with a 10" slick. Hopefully, you will have the same experience. I assume you have the Street Twin, if not the clutch will never hold. You shouldn't sidestep it, but just let it up quickly at ~3,000rpm for starters.

Good luck.

Hoosiers will hook better, but know what this car is intended for(street use), the M/Ts will last longer.

I'll take a broken driveshaft for $100 Alex. :) Put a 400 behind it and be done with it. You can probably sell the T56 for the price you'll pay to have the 400 built. :cool:

I'm wanting to milk the T56 as long as possible, I like a 6-speed car for the street. It just makes the car a lot of fun to drive overall and allows me to keep some driveability.

What driveshaft should I go with? It has an aluminum driveshaft at the moment. I could get a carbon fiber driveshaft, but if I don't have to...I won't.

I've been reading a lot about the output shaft problems, I'm just going to hope for the best. :D

THanks for the help,

You need a heavy duty steel driveshaft with 1350 U-joints. I am sure that a CF shaft can be made to work, but the current ones are shoddy. A functional one would probably be $1,000+, and the real world advantage over a steel shaft would be small anyway.

I have had good luck with Denny's shafts: http://www.dennysdriveshaft.com/ The "nitrous ready" shaft is awesome for $336.

I used a Spohn last year and will be doing so again this year.

Carbon fiber is good if you're a track only kinda guy. On the street, it'll broomstick on ya. :(

Hey bud, that's alot of power to be making for the street. It would be fun i'm sure, but i don't know how it would work. If i made that much power, i would only race the car. I would put a powerglide behind it with a transbrake in it, and a different drive shaft. I like the feeling of launching my dragster at 5000 rpm's. You need a better tranny though i think to launch it that high.
