i took my truck to the dyno yesterday, and i got 293 rwhp . my mods are AFE CAI, Dynatech Headers "offroad" and HP tuner program. I dont know if this is a good number i still didnt compare with similar car with same mods and if someone can tell me what is the 5.3 rwhp stock ??

 

good numbers for bolt ons

 

Very good numbers. 2WD or 4WD? What wheels? What transmission?

 

thats pretty good..i put down 275rwhp with the mods in my sig.

 

thanx..2WD, the wheels and transmission are stock.. i think the transmission is 4L60E correct me if im wrong.

 

thanx, do you know what are the stock numbers for this engine. i searched the net and got 2 different rwhp numbers... 221 & 241 i dont know if thats the real wheel horsepower.

 

um im not sure..i think its a little more than that..more like 260 i think.

 

Depends on the type of dyno you check it on. The Mustang dyno i ran on would rate a 5.3 like mine at 230-240ish RWHP. After my mods in sig (not including cam) pushed 280hp 294tq.
The Gray 02 for sale in the classifieds pushed about 294rwhp with cam on the same day. But i think it needed a lil better tune myself.
If you ran on a mustang dyno your doing pretty good.

 

mine was on a dynojet

 

its a dynomite dynometer, but it was calibrated to read the horspower exactly like dynojet

my next mod would be the CAM, i searched the forum and went clueless i dnt know what to choose now. Comp Cams would be the cam i would go for i want something that would help the bottom end without sacrificing the top end. what do u think of this one http://www.jegs.com/i/Comp%20Cams/24...51-11/10002/-1
