It was the same night I was running 11.8's with consistent 1.75 60's, I was surprised that he was not quicker off the line I have to confess. His tuner told him he should be in the 10's easily and he was not so happy about his times.

I do not want to knock centri guys in any way and I think that big power can be made from them no doubt, what I do see in their dyno sheets is that the boost comes on significantly after 3.5-4k and maybe that would explain why the top end looks great...but not so hot off the line.
Ah, sorry, I was still thinking in trap speeds. Yeah, that seems like it may be what's going on. On a road course, where you're rarely accelerating from below 3k rpm, I imagine they're fine. For the price though, this setup looks hard to beat.
