5.3L H.P and Torque output
hey, i need some help! there is not a dyno in my hometown and i want to know how much power i possibly have. Stock is 295hp and 335 ft/lbs. With the mods i have, can any of you give me an estimate of what i have at the rear wheels? i am guessing i have 295 and 335 to the wheels.

your guess on rwhp might be close but id bet you have more tq, chevy high perf. mag did an 05 truck with 5.3- stock rwp was 249 h.p./298tq. THEN they added a JET tuner,JET M.A.F. and JET throttle body spacer and ended up with 284 rwhp and 358 rwtq. you have a way better tune and air intake and exhaust so i think your probably at least 300 rwhp and around 340rwtq. just an educated guess but someone with your mods might chime in. but they tested on a mustang dyno and i dont know how accurate they are.

weve all gone over the whole MAF screen arugument way too many times to say that thats hurting him, thats not been proven.but i think his guesses on hp and tq are close. plus i think CHEVY HIGH PERF exaggerated a lil bit with the jet stuff, i mean that is one of their long time advertisers.
