New Here, 03 Cobra Whipple 2.3
Just introducing myself. I'm new to this forum but have owned my car since 2007. Up until last week it was a pullied Eaton (non-ported) with all supporting mods. Best E.T. was an 11.85 @ 121.3mph on Nitto 555Rs. As of last week, my friend and I both installed Whipple 2.3s, Mafias, 63lb injectors, BAP (he went the twin GT pumps route). We did all of the work ourselves over the course of about 5 weekends. Dynoed tuned them in Harrisburg, PA last Thursday and I put down 601whp on 3" pulley and 93 octane, and 641whp on 2.75" pulley and 100 octane. He did about 1% less respectively. Hit the track Saturday to attempt to break my half shafts and get that over with but could only spin through 1st and 2nd (track is terrible). Best I could pull off due to letting off in first and second gear both was a 12.1 @ 129mph (93 octane tune). I was using 315 Toyo Proxes. Anyone else run them? I can't tell if they are as good as the Nittos or not. I am considering picking up some Mickey Thompson ET Streets for the track.
