The problem with dyno numbers and a blower is how long they can make that number for. Pretty much a question of how much power does it make over a certain period of time. The IAT's for example will be considerably lower on something spinning that fast in first gear vs. third gear. How long does it take for that number to fade if you keep spinning it there.

With the right intercooler it should be pretty good. At the end of a 1/4 mile run 10 degrees F above ambient and thats made a Huge difference. I posted a plot with IATs in this thread and bascially IATs were pretty steady at 90F.
