Guys, I've got a 95 z28 that I have been using for DE's and modding step by step. First step was brake upgrade to c5 brakes, then suspension, next was upping the power a bit with lt4 hotcam and headers, bolt ons...makes 330 rwhp right now.
Well I just ordered a set of LE2 heads from LLoyd elliot with his LE2 cam, I am going to be looking at around 400-410 at the wheels. WHic will be good because I need a bit more power on the straights on the big tracks. I am contemplating dabbling in AI and maybe some other amateur racing series...I know AI has a Weight/RWHP limitation. I guess if you go over you can add ballast, but that would be a negative impact on handling and braking. So I guess the best solution is to lighten the car as much as possible and set the hp to the max... Is it possible to restrict your engine with a restrictor plate when running Nasa AI? Does anyone have a good guess at the weight of a 95 z28 m6 with the rear seat and all stuff (carpet etc.) in the rear removed? |

Sure, you can use a restrictor plate. You dyno the car before the season or after any power changes, then when you come off the track they weigh you. If you have more horsepower than 9.5 to 1 (weight to power) or more torque than 9 to 1, you are disqualified.
Rules are here: http://www.nasaproracing.com/rules/America...-Iron-Rules.pdf Ask Mike P. about racing an overweight car. I think he still has a full stereo in his car! I don't know how he's scooting that thing around the track so quickly. Jason |
