Gee, that's fast. Thanks guys.
One last check...sometimes it would pull as expected, but then drop off.
I'd say that the longest pull was from t5to t6 at Road Atlanta which equates to maybe 1/2 of a mile.

So look at I/C cooling circuit?

I'll start my search...

Also, have othes done track events with SRT-6s? Let's hear about some fun experiences. Perhaps I'll see you at NASA events or BMWCCA events in the southeast.

Thanks, RP
