VY SS ls1 made 320hp the the rears
Have VCM 3 cam(228 / 232 0.597” 112 LSA) , VCM OTR, Maffess tune, twin 2 1/2 cat back
Possible big set backs include HSV exctractors and standard cats and auto(on dyno figures)?
So looking into some pacemakers tri ys or 4 into 1's? and high flow cats ( still unsure which to go )
and since had heads off to replace lifters, so tickled up the heads while they were off
Any ideas if its going to be about right for the setup or its a little low in figures? Kept making power to 6700 RPM where we set the limiter.
Cheers
who tuned it? has it got an aftermarket stall converter?
and definitely go 4-1's with cam and heads
The HSV headers won't affect the dyno readout that much, just shift the torque higher in the revs and give you more top end.
Could be the tune, if the timing is wrong or the fuel delivery is out it will drop off and only make good torque down low.
