sperkins Posted November 12, 2010 Share Posted November 12, 2010 With 275's, 3118lb comp weight gives you 8.4:1 (.1 for weight) = 371.19hp max. At bare minimum comp weight, my TTA C5 is currently 9.0023:1 with 346.8 rwhp (+/- 9.04:1 when on track) and it does pretty well. Weight and setup is more important than hp imo.

Varkwso Posted November 13, 2010 Share Posted November 13, 2010 ....The 2010 TTA National champ started out in HPDE 1 this year running Hoosier A's from the start. So if your goal is TTing then maybe it's not so bad. Still does not mean it is a good idea. I know there are several less C5Zs in the world due to this practice..great for spare parts though.

Vettedoctor Posted November 15, 2010 Share Posted November 15, 2010 I agree it doesn't work for most people, but it did work for him. He did have previous track experiance (on cycles) so he wasn't a complete novice. But for most people it's better to start out with street tires and work your way up. All I'm saying is that as you are comfortable use whatever tires you want. Quote Link to comment Share on other sites More sharing options...

yakisoba Posted November 15, 2010 Share Posted November 15, 2010 (edited) With 275's, 3118lb comp weight gives you 8.4:1 (.1 for weight) = 371.19hp max.At bare minimum comp weight, my TTA C5 is currently 9.0023:1 with 346.8 rwhp (+/- 9.04:1 when on track) and it does pretty well. Weight and setup is more important than hp imo. I think you can get round that 0.1 for weight if you go to 3201? Sorry I got it wrong the first time. So 3201/8.3 = 385? Going 83 pounds heavier gets you 14 more HP? Note that I'm not saying this is better, but rather that it's another option if your engine makes that sort of power. My personal belief is that the lightest possible car within the rules with the right HP is best, almost all the time.

kbrew8991 Posted November 15, 2010 Share Posted November 15, 2010 you can go too far with anything gotta have SOME power to push the car through the air on the big end Quote Link to comment Share on other sites More sharing options...
drivinhardz06 Posted November 15, 2010 Share Posted November 15, 2010 . My personal belief is that the lightest possible car within the rules with the right HP is best, almost all the time. I would take 83 lbs off the car vs 14 more peak hp all day, every day Quote Link to comment Share on other sites More sharing options...

dans2k Posted November 16, 2010 Share Posted November 16, 2010 what about a 2850lbs Turbo s2000 with about 280/300HP in TTA? Quote Link to comment Share on other sites More sharing options...
yakisoba Posted November 16, 2010 Share Posted November 16, 2010 what about a 2850lbs Turbo s2000 with about 280/300HP in TTA? Far from the original post, but the turbo is going to require a reclass from Greg, so it'll be a one-off. Power to weight should not be an issue though. Yes, one good way to go is to pick the best body (low frontal area, slippery drag numbers), good suspension, get an engine that's in the ballpark then roll the dice with the national director for a reclass. But it's a time trial. For the same money, you could go pretty well into AIX or ST2 or something. Quote Link to comment Share on other sites More sharing options...
z06tracker Posted November 27, 2010 Share Posted November 27, 2010 I don't know what his torque curve looks like on the dyno, but I have a good idea based on how he pulls away from me after exiting corners. At bare minimum comp weight, my TTA C5 is currently 9.0023:1 with 346.8 rwhp (+/- 9.04:1 when on track) and it does pretty well. . yeah but what's the torque to weight ratio, and what does that torque curve look like Quote Link to comment Share on other sites More sharing options...
