My two cents, last year when I still had a stock unopened motor. TA49 tweaked by Bison, RJC 315 FM, 80# inj. Alky and 93 w/ 24 # of boost, 6.1 wide band chip, TR6,Hotwire DW300. This motor dyno 436 HP at the flywheel, it made 316 HP at the rear wheels. Richard Clark said this is or was some what on the higher end then he guess. Clint tune the car. The one before me made 285 at the rear wheels. Cars were almost the same other then a stock turbo, however it had Fast. Just shows no two cars are alike
