To day I send 2 hours on the dyno to test 2 mods that I did in 2011.
Normaly I always do a dyno session after any power mod but since last year I was plaged with the ECU pulling timing and not knowing it untill I blew the tranny on the drag strip.
The flywheel was badly cracked, which we think it was affecting the knock sensor to not be happy thus pulling timing !
It was difficult to have much of any consistense pull after pull but since the flywheel got replaced, I do not have any problem with that !
Soo today was to confirm 2 mods.
1= HR vs VHR intake manifold (
you can see my picture when I did the conversion)
-
2= Throttle Body OEM stock @ 60mm VS bored at 62.5mm
The AFR were ajusted before the recording pull.
