GTM TT vs Greddy TT
incorrect information !!?!?!?!?!
man plz just think, how ?!?!?!?!?!
4.2 + 12 psi + 91 octane = 630whp and 630TRQ
thats allot for 12 psi on a greddy kit with just 91 octane, noooo way
man, that means with GTM stroker kit ull hit 700whp with just 16 psi !!!!!!!!
i dont mean any thing bad but lats face it, all that power didnt come out with just stroker!!!

Again, I mean absolutely no disrespect.
Nonetheless, here is my dyno graph on a 3.5 L motor with the Greddy kit at 13.5 psi (the picture says 14 psi, but Jack rounded it up to the nearest whole number; it was only 13.5 psi - I was watching the EVC readout). Now, this is corrected for temp and humidity because it was a very hot day here in So. Florida when we made this run. Weather corrected for the temp and humidity, we achieved 584 hp. Uncorrected hp was in the mid 550's. Also, this was on a Mustang dyno.
Now, I don't want to get into the whole discussion of different dyno numbers, but if you research Mustang Dyno vs. DynoJet on Google, you will get a general idea between the measured differences. I think GTM uses a DynoJet, and I think their dyno results are very achievable with a Greddy TT 4.2L motor on their dyno. Again, this is my opinion. Anyway, here is my graph:
One important note, the timing was not as conservative on this dyno run as my last dyno run. I don't remember what the timing settings were in the one shown here were, but in my 609 hp run (UNcorrected) my ignition timing was set to 9 degrees between 3500 rpm and 5000 rpm.
Perhaps Sam or George can chime in on some of the specifics on their dyno run.

sure there is no hard feelings
thanks for the info and the dynos ,ur sharing and carering.
this thread has allot of info
ppl will undertand more about the Greddy kit and the power it can make with all the Diffrent setups we talked about.
