Now that's funny, wrong, but funny. TJ, didn't your mother teach you it is not nice to talk about people when they can't defend themselves. Congrats on the new numbers, let me know when you go back, I want to go.

Interesting. TST 6 makes more power than TST 9.

I've never heard of a Smarty giving best dyno results with sw #9-- usually it's #3 or #5, I hear.

I'd like to see what you'd get with SW#3 and TST 6- I bet you'd pickup a couple hp, and the peak TW should be noticeably higher because you're not bogging on the bottom.

What RPM is your peak TQ occurring at? How about peak HP?

With a factory HO cam, you'll see peak tq usually at 2000-2200 rpm or so. If it occurs earlier, then the turbo is too restrictive and you're hitting choked flow pretty early (that's my case with stock charger and 150hp sticks). If it occurs later, then you're overfueling and putting the fire out down low.

Actually Hohn, my best dyno pulls are on that tier too. My best ones are on sw8. I used the Edge Comp for timing and TST pm3 fueling. I made some pulls on sw2 Edge Comp and TST and it was close, but still best were on 8. It was about a 10 hp difference give or take. Maybe it's a manual truck thing?

I know Mike D was kind of the pioneer of sw3 on the Smarty at the track and I know he does get better track times with it. I think the theory is that 9 fuels too soon and the pump can't catch up. Sw3 leaves a little fuel for top end at the traps.

I've made track runs in sw3, sw7 and sw9 with all of my best times coming on the higher sw's. My theory is that in between shifts, the VP44 has a few fractions of a second to catch up where as on an auto truck you aren't giving the pump a breather. Those are my observations anyway.
