Dynamometer Results & Comparisons - Gear Change... What do you suspect will be the result?

So, last spring I did a gear change, and retuned my junk. I was at 424hp,395tq on a dynojet, and speed inc tune. Blew the heads off the car, and put on Trickflow 220s and swapped to a 4.10 gear. Had the car retuned at Straightline on a mustang dyno for 425/400tq.

Also added qa1 single adjustable rears since the last runs. Seeing as I up on power a bit, and the gear swap and suspension, what are your guesses if the rear holds up for a few passes? Old times are in my sig.

You won't finish the race cause that 10bolt is going to be like Whitney Houston!

Yeah, very funny, but it still rolls under its own power. Yours done yet?

Should be by Friday bud, all it needs are the accessories ie w-p, p-s n compressor on. The abs delete and topping it off with the radiator and she's done.

So with the new heads and gear swap you only gained 1rwhp 5rwtq ?

the gears will not take that much power I did back to back test swaping 9'inch rearend with 4.11 gear on H/C/I M6 Z28 Before it was 459rwhp after the 9" rear/gears 450rwhp a lose of 9rwhp but better TQ and mid range power.

I would think the heads should gain atleast 20rwhp unless your old one wasnt stock?

If you didnt blow the 10bolt and have traction I say 11.7@116mph :D

Old heads were worked ls6, and it made more than 1hp when you figure I went fron a dynojet dyno to a mustang dyno... if it holds together I am thinking I will see the main difference in times as I was crossing the lights at the bottom to middle of third, now it should be right at the top of third.

My bad man I didnt read you retuned on mustang dyno :bang:

I believe you'll be crossing the lights in 4th gear...

Overdrive? Its a stalled auto.
