326whp/341ft-lbs EFR 6258 BP4W
Here's my dyno info as much as I can remember:
'94 block Supertech pistons 84mm, 9.5:1, Wiseco rings, eBay rods
'00 cylinder head Manley SS +1mm valves and Supertech light double springs
Clevite bearings
QMax reroute Supermiata Crossflow Rad
MS3x
E70 fuel + Flex sensor
Trackspeed Engineering EFR 6258 kit
Ceramic coated manifold and down pipe
Precision intercooler, FM silicone intercooler tubing
MKTurbo 3" exhaust
Flow Force 640cc injectors
Fuelab AFR @ 60psi
Flat top intake manifold
Skunk2 throttle body
Turbosmart EFR BOV
NB2 6-speed + 3.63
Max power was 326/341 at the wheels. Boost crept to 22psi and then tapers to 18psi by redline which is why torque is so high. Only using stock EFR single port WG can, need dual port for more control. FF640 injectors running at 60psi base pressure reach a max of 93% duty cycle on this power run. Tune was dialed back to 18psi across the board and max duty cycle dropped to 83% and power was 313whp/320tq. Limiting factors for power are injectors and wastegate duty. It made 290/290 at 14psi also.
Yes it's fun!

Nice, thanks for sharing it with us. I was searching for this https://casinosanalyzer.com/online-casinos/new-casinos link because I am looking for the new online casinos sites and while searching for it online, I found link to your post as well.
