Any idea what your HP/torque numbers are at 2000-4000rpms?

I am now running the Sportsman EFI with the same throttle body... it gives me more options and the EZ had filtering problems. but the 109 is not a problem.. runs great!
I start to come in strong at 2000.. and I think it was around 400 but i would have to find the last dyno to be sure. but 2000 up the tires spin all the way through and including 3rd starting at 2000 with 190 tread ware tires.

And does everything clear with these heads and headers?

I have the heads, mine are the competition ported 220's, but I don't have those headers, I run the Kooks through 3" mandrel bend X-pipe and ave no issues..

I have Brodix -10 heads with raised exhaust ports and Hooker Super Comp headers and there were no clearance problems with stock steering components or now the Steeroids rack and pinion.

I have AFR 210 Eliminators (also raised .250", with angle plugs) with Hooker Super Comps. Everything fits, no issues. Good spark plug clearance.

Thanks. Hearing about the Steeroids is a bonus, since I have that system as well.
