I got that you did a reversed, ported GrimmSpeed intake manifold. Was this for drag racing?
Looks like the full torque wasn't realized till after 5K RPM. Looks great on the top-end, especially if the fuel supply pooped out!
Yes, this was with about 30min of tuning on the road, just to get the car broken in and running before winter hit. Tuner thought it might have 570whp in it before I need a bigger turbo. Stock head ports, stock valves, radius valve job, BC valve springs/retainers, GSC S2 cams. Has GrimmSpeed TGV deletes and ported manifold. It's a street car that'll see occasional the drag strip or road course.
Also, this was my first trip around the block with the car, very little throttle and almost no boost. Man are these turbos loud!
