okay guys, im torn between these two set ups..

i have this theory that the 2.6L stroker with the HTA30R would spool like wild fire and make 600whp on race gas with a HUGE powerband. If i was hitting full boost by 3800rpm on my 2.4L in my SRT4 what RPM would it be safe to say that the 2.6L would spool the 30R at? 3200-3400? if its not worth the stroker hit to pick up the fast spool time from the 30R then i may just continue on with the Built 2.4L and Run on to a HTA3582R.. input please! thanks guys!

2.4/2.6 = 0.92307692307692307692307692307692
0.92307692307692307692307692307692 times 3800 = ~3500.

Safe to assume that's the difference, provided 2.4 is 2.4, and 2.6 is 2.6. Having actual numbers would give some bearing on that as well.

Also, that would be assuming 100% efficiency, and that both would have the same efficiency. It's pretty safe to say you'll lose a small amount of efficiency on the stroker, provided nothing else changes between the setups.

I was not hip to the spool valve idea. Very snappy part.
