im going with front mount turbo set up on my 5.3. just wanted to see if you anyone has any numbers with a turbo on their 5.3 such as how much boost have they ran or how much power evan better if they got any time slips for their setup. i plan to put everything back to stock and put an ls6 cam.not quiet sure on the gear yet 323-373's??

Post up!!!

 

Steve's truck that I tuned is the best so far on our chassis dyno for a stock long block 5.3l.

With a LS6 cam, dual springs, one piece push rods, custom front mount single with a 468 on it.

Through the 35" tires and 20" wheels. 4l80e, 14 bolt rear.

19psi......681 rwhp.

13lbs boost, stock bottom 5.3L w/ ls6 cam and springs, 4l80e, 3.73's, 20"s with fuel issues running lean (12.7) afr on top i made 500rwhp and 512rwtq...

 

if I can get on the dyno this weekend I'll let you know

 

Wow I feel like Im doing something wrong.... Looks like turbo is where the big #'s are.

 

Just a little ole MP112 and a GT2-3 cam with 8 psi made 504 RWHP......

 

stock 5.3 block and heads? What was the temp and elevation? Could a stall converter hold back the #'s?

 

Was kinda wondering myself too. I wanna up it to 15# but just was curious.


Hellbents10: Was there heads studs involved to hold 19#? How much timing were you running on 19#?

 

Stock other than the cam.....Sea Level 75*

 

Wow! That gives me hope
