How much power do you think im putting down??? 6 #'s on stock 4.8 with3k stall and predator tune (soon to be retuned by BB)
3.42's, peg leg RCSB
Thoughts on track times?

 

Probably 340-380 rwhp....grt in dyno tuned

 

I would guess 330-340rwhp/350-360rwtq

 

Stock Exhaust? If I were you I would pulley down before paying for a custom tune... Get to at least 8#.... Mid 13's now maybe 13.0's with headers, pulley, and a tune. AND TRACTION!

 

My stock 5.3 7#'s with shorties and a dyno tune made 386 rwhp and 408 rwtq

 

You dynoed it with you current setup?

 

No....been having some transmission issues...i did dyno it but found out later my intercooler pump was bad and my trans lines had been resting on my headers ....i think my dyno pull was 445 hp with no intercooler pump and trans would not lock in 3rd.

 

What sort of trans problems? I am looking at the PB lvl 3.

And for I/c pump, look at the meizere $200 one from summit, 20gpm iirc. It is supposed to do a much better job of lowering iat's than the slower flowing stock one. I have one but haven't had a chance to install it. MB E55's use those pumps (same blower as us) and report 30-40rwhp gains.

 

Has the extra flow, with no other changes, proven to lower IAT's in the Maggies? 30 to 40rwhp gains would require some pretty seriously cooler intake air.

 

Id say a lilttle over 300 on bb dyno since it reads super low
