O.K guys. What is the most HP/TQ that has been made with a new YSi? What was the combination? What is the best ET/MPH? With what combo?
I made 645hp/696tq on a 302 with 27 psi air-to-water IC (27/77 cog) (6800rpm engine)through a powerglide. The AF was 12.0 to 12.5 (lean)The peak tq was before or right at 4000rpm. Timing was only 17 and air charge temp was 65. I was still running a Mass Air Meter ( which was not cal for the big blower ) with a PMS and injectors that were toooooooooooo small. I am anticipating making more with the same combo but now with a FAST seq and 96's.
Then i am going to put in the new 345, new heads, new cam and try it again.
Let's hear them!
