[Shotimes] 89 sho dyno charts posted

[Ian Fisher]

With the +20's, I'd expect a lower tq peak but to hit
that tq peak much sooner than with the stock cams. So
even if you are down a few lb/ft on paper you may be
making your peak much sooner in the rev band. The hp
gain looks nice. I didn't look at the charts, just
going by Justin's numbers. How does the car feel? Butt
dynos obviously aren't reliable measures but does the
car feel like a dog or does it feel better?

I guess we'll see how my +20's perform. I  won't have
any old 3.0 dyno info to put it against but there
really isn't any point. The 3.2 that I am putting in
is heavily modifed by comparison and is either fresh
or refreshened where applicable. I'll also be
installing the adjustable cam sprockets which may be
something that you'd find beneficial for moving the
power up and down as well as decreasing overlap. Are
you running any tuning aids such as an LPM or TwEECer?
