Effin' sick dude, congrats! What are you doing for fastening on the heads? Just ARP studs, no pushing water at that boost? I would really look into some adjustable rockers, AFR's are notorious for screwing up valve guides with stock rockers. I had 4 in each head that had to be replaced, buddy had more, and another local car is starting to burn oil too. Sick setup, I'd like to check it out personally at TX2K11 if that's cool.

 

Great power!! Bad *** car! Congrats

 

Sounds good man hit me up when we get down there. THe car has Just ARP studs and LS9 gaskets. I am on stock rockers and will probably keep it that way for awhile. I had a set of comp pro mag rockers on my n/a setup and they fucked some **** up...caused serious valve float at high rpms

 

damn! that was impressive congrats for getting the numbers you wanted

 

Killer build

 

wow crazy dyno vid, id love to go for a ride in that thing

 

Eh the 160's are a little rich on Decel and idle but it doesn't mess with the way the car runs. It was either $800 bucks for a set of injectors and a box or almost $1300 for high impedance injectors..

 

damn I wish I had E85 available in my area...great results

 

I ll assume GT88 is a T6?

 

yes & 1.08 AR

 

Would you have preferred high impedance over low? Personally, low > high IMO so I'd say you're good. I think the only high impedance injectors I'd try would be ID1000's or ID2000's. Local E85 guys love them. What's your duty cycle on the 160's?

 

awesome job. def have some nice #'s

 

so how much timing did you have into it and peak power if you dont mined me asking

 

the 347 that could , congrats my frind

 

damn!

 

Aluminum block 5.7 L still has ability to cope with that much power lol..

 

Wow I am blind! Thanks man.

 

The regulator was not increasing fuel pressure with boost and with a base pressure of 45 PSI we saw a pretty high IDC. I had the pressure turned down while I worked on getting the car to idle a bit leaner, and get light cruise afrs leaner as well, currently in the 12.0-12.5 range. Ill mess with the tune more in the next week.

As far as doing triple pumps in a plastic tank, its a PITA, I forgot to snag pictures of it.

 

 

OMFG! I read used parts, stock stuff, and 1100RWHP in the same paragraph. WTF! Only in a Pontiac! Thanks for making my car look whimpy.
