Well I took the car to the track last Wednesday and I tried out the just installed TCI trans brake on the th350. WOW!! that is cool!! I have the boost controller set to 15PSI max (it did spike to 18 though using the "recall hi boost" on the controller"). Wide Band sensor showed rich in the mid to low 10's all the time, But at 3800RPM's and 5psi launch it spun like crazy and I had to back out and get back into it. I ran a 12.6@116mph wit a 2.33 60' time. Tried it again, this time I left at about 3200RPM's and 2PSI the car loaded for a split second and then unloaded and the tires spun allitle but quickly grabbed. I ran a 12.29@114.9 with a 1.9 60"
Please look at signiture and tell me what you think as this is a 63 chevyII hybrid? Am I close to where I should be at 15psi boost? What should I expect to see when I slowly tune/creep up to the 25 to 27psi. I would really appreciate any input and if anyone has run that precision "STEALTH 70" turbo please give more info on that as my forum searches have not turned up much. Thanks again, James :biggrin:
