Some of you may remember a thread I started a while back about my H/C results:

http://forums.corvetteforum.com/c6-z...x-results.html

Well I finally got some headers on there and had it tuned on E85. Setup now is:

WCCH-X heads milled .030
Widow cam
Halltech MF103
Stainless Works 1 7/8 headers with gutted cats
85lb. injectors
E85

Peak gains after the headers/E85 were 45rwhp and 48rwtq but the gains under the curve were pretty crazy. Down low I picked up almost 100rwtq! The car was dyno'd in 109 degree Phoenix weather so when it cools off outside I'm sure the numbers will come up a little. The dyno numbers don't concern me because the car pulls like a monster now. Now I know what all the fuss is about H/C C6Z's. Moral of the story: Don't do a big *** heads/cam package without headers

Big thanks to Joe and the crew at CPR. Joe has been helpful throughout the entire build and responds almost instantly to whatever questions I've had, and I've had a LOT. If you need LS work done in AZ, I recommend you check them out.

Very nice!!! What was total timing this time?

CHIWS6

great numbers! what changes did u do to the fuel system in order to run e85?

SlowVet05

Not sure on the timing. Bigger injectors is all I needed to run E85.

I just got my WCCH-X heads put on and I have the widow cam/headers/Halltech intake/Bullet exhaust and my car made almost the same numbers as yours. Mine made 550/490. Only have 91 octane here in Oklahoma.

Congrats and nice numbers, what are the specs of the widow cam? Also how much does it cost to do a E85 conversion? Thanks

SlowVet05

Carlos doesn't release the specs, but it's BIG. E85 conversion for me was just the cost of injectors which I found used for $225.

VictoryRedZ06

Wow cool! If I just convert to E85 how much rwhp and rwtq would I gain? I have heads/cam also NO headers since Im in California

SlowVet05

I didn't get a 91 tune but from what I've seen from a few buddies of mine you can expect about 20/20 gains.

VictoryRedZ06

Thanks its definitely worth the conversion

Why the numbers so low on a dynojet. shouldn't it be 600 area on E85?

Also congrats on the new set up.

SlowVet05

I'm not too concerned about the dyno numbers, the car pulls like a beast so I'm happy with it.

MTPZ06

Ambient was 109* Would like to see it again at 65-70*...


That's what matters

You don't have to upgrade the pump when you go to E85?

SlowVet05

I didn't have to.

Cordes Performance Racing

no z in az will get there w/o being high compression

at his power level no but around 575 rwhp they start to run out of pump. the walbro 450 is a great replacement.

I have a 06 z06 with a synergy smog set up heads and cam. Through manifolds it made 548/503. It does have a katech bottom end in it.
