Spearco 2-221 and buchcar 2 1/2 exhaust ?s

[HITNRUN]

I have read about several dsm's running in the 10s with the 2-221

Right here. Mine went 10.565 @ 137 MPH with a spearco 2-221.

I've never run it on pump gas, but on 105 unleaded it traps the same as C12 or C16. The injector dutys are pegged, to say the least. I've got 780s going in before I run again, along with a few other tricks. Hopefully I can see 10s on this turbo. It's been good to me and I'm not ready to give up on it yet. It's an FP20g-05H, I think it's clipped about 15 deg. Buschur's are clipped even more from what I've heard. You should run just fine with it.

So what kind of boost do you run and what kind of dyno #s did you put down ?

boost is around 26-27psi, never dynoed the car. I'm putting a wideband in soon and plan on some dyno tuning for the new injectors before I hit the track again.
