That electric turbo is really an injector cooler. So that block [probably] never saw boost. More numbers, my 260z had an L24 that was bored out to an L26 with a e88 head and a stock cam. I made 140hp on a dynopack dyno(bolted directly to the hubs) with rebuilt SU's. Like leon said it exaggerates the numbers a little and does not take into account traction from the tires, so I'm guessing around the same as leon. And that car felt snappy with the 3.9 gearing in the back. It was a completely tame street car and felt awesome. I do not have any trap times or 0-60 times.
I need to get another dyno session now since I installed my L28, triple webbers, headers and cam.
