Stroker vs. ATI
Looking at some of the initial track numbers, it seems as though the superchargers are more bark than bite. They're putting up big dyno #'s, but it doesn't seem that the HP is carrying over to the track well. Does anyone have some #'s that show this to be incorrect?
The current tuners have strokers running mid 10's w/o nitrous. (What is the fastest normally aspirated time, BTW?) I haven't seen any ATI car in the 10's so far. There was a post here last week where a 570hp ATI car was running 11.80s. Much lower HP strokers are running much quicker than that. Am I just missing the other times?
I was originally planning on a heads/cam/ATI instead of a stroker, now I'm leaning back to the stroker side of things.
Thanks for your feedback!

Re: Stroker vs. ATI (97C5)
That's seems to be the case from everything i've seen todate. Not sure why. I assume it's due to the fact that the ATI is a centrifical (sp?)SC and it has to build boost as RPM's increase, where as the strokers start out with mucho HP/TQ.
I wonder what the Magnuson SC will be putting down at the track since it's a roots type SC? Either way i got my eye on the Magnuson SC for now. I'm hoping we'll all see some actual performance data soon.

That's because of are under the curve. ATI doesn’t add much (if any) power under ~3Krpm and in drag racing launch is everything!
