I see people with dyno readouts of their gms1 sstc's. I see whp numbers in the 270's consistently with just the tune or an intake. If we calculate a 15 percent drivetrain loss wouldn't the crank hp be around 310-315??? And measured wheel tq at around 290 thus making around 340-350 crank tq?? Think maybe we have a 50 hp 90 tq increase....... And no freaking way is a 20 hp gain gonna cause wheelhop at 40 mph in second gear and a 7lb increase in psi equals only a 20 hp increase???

 

I don't know much, but I do know that the small turbo is great down low, and that there is almost a 50hp increase at the bottom ranges. Unfortunetaly, with the small turbo, the thing can't put out up top and the difference becomes smaller up to only a 20hp gain at the top levels.

Other guys on here are geniuses and know more.

my results

 

My results & a dyno graph are around here somewhere...

I made 277whp & 301wtq with the GMS1, K&N Drop-In Air Filter, Dejon Hot-Side Charge Piping & a HKS BOV.
