Does anyone really know what these tranny's can handle??
I was doing some math based on the dyno of the 5.7 hemi
5.7 hemi 04, 05 , etc. 300c/magnum
crank hp 340
crank tq 390
Actual dyno test show:
263 rwhp loss ratio of 1.29
280 rwtq loss ratio of 1.39
After GSM supercharger
374 rwhp x (loss) 1.29 = 482 crank hp
353 rwtq x (loss) 1.29 = 490 crank tq
on one of these posts i read that the highest tq rating on the 300 tranny is 428 < is this figure rated as max tq to wheels or crank?
Just for the hell of it if you were to put that supercharger on a srt-8 these are your estimated figures 
based of same ratios
crank hp =425 actual dyno 329
crank tq = 420 actual dyno 302
After GSM supercharger
rwhp = 467 crank hp = 602
rwtq = 380 crank tq = 528
