Regardless, there is absolutely no evidence that this car isn't competitve as is. The T3 Rx-8's (at the same spec weight) seem to run good ITR times, and they should be significantly faster with the increased mods allowed in IT.
At the time of the original proposal the sheets were correct. 2 years later and a ton of dyno time have the car up above 200 rear wheel. As I said, most guys have found a way to get the stock computers up close to 200 and the Motec cars make a couple more. All numbers I am quoting are for a Dynojet with SAE correction. Certified sheets have been provided to the ITAC with those gains and as I asked in an earlier post, please send in any you might have to prove more or less and be ready to back yours up. Read a few unbiased magazine articles that all lost HP when they tried to add exhaust,intake, etc to these cars. When ITR can out qualify ITS at the ARRC, then we can talk track data. Right now most of those times are pretty soft.
