Once again I would have to second cool 84. Go to the track before making any assumptions. Our cars make there most impact on the topend. Your not going to be running two many 1/4 miles on the streets to see this. SCANTOOL, TUNE, TUNE, TUNE. If you havent made it to the track yet then you probably havent really been able to really dive into the art of tuning. Need to know what your working with before doing anything else, IMO.
If strictly a street car, seems to me that tuning for 1/8 mile would make a really quick car. When running 1/8 mile tracks, from what I hear, they tend to pump up the boost and/or timing. Just a thought.
By the way, Havent ran my car since september, but I was finally beginning to make some gains with tuning. gained about 5-6mph and .6-.7et within 2 weeks without changing any parts. 0 kr and O2s in the 840-860 range, so plenty more room for improvement yet. After seeing the steady gains, my brothers (both have intercooled TRs) were finally sold on the alky injection. Im making more power on the topend then one of them, and about the same as the other one whose car is capable of 11's if he ever stops BS'n and tunes it right. Well, we installed alky kits on both of their cars a few days ago, and I completely revamped mine. IMO, alky is the best bang for the buck hands down. It will complement any mod you currently have or do in the future. Contact RAZOR, he is the tech moderator for the alky forum, and a very cool guy to talk to. He is very knowledgeable and would be happy to advise/help you (Im sure he knows a little something about propain too, if you want some opinions on it). Quite the electronics expert aswell. If you go the alky route, he will get you right with UP TO DATE technology, including his progressive alcohol controller, all designed by him (no more talk about bogging, or hobbs switches to worry about either). Right now I dont think there is any other logical route to go for an alky kit. Only thing that kind of pissed me off is all the stuff I had to disconnect to install the new stuff. All the time I took putting my DIY kit together and changing it over the years. Wish I had this setup to begin with (anxious to get back to the track sometime soon).
