Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq This was a buddy of mines car. He has AAP Stage 2 6.0 heads (they flowed 342 <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> @.600" intake and 237@.600" exhaust) and an AAP custom 230/236 .598/.598 111 lsa cam. The car has a lot more in it, this was done with a stock TB and MAF (not descreened), Mac headers (ball flanges cut), single cut out on the i-pipe, 17x11's with 23 psi (pretty low), M6 stock rear with 3.73's, LS6 intake, no ASP Pulley, minor LS1 edit tuning (gear cal., rev limiter, cags, idle, no fuel, no timing) We're hoping for high 440's with some more dyno tuning and the bolt ons <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Hey that sounds like my car! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Thanks Tony. I'm very pleased with the results. Mark hasn't done any tuning for power yet, just to get it to idle. I think with the MAF and TB back on, and tuning we should be able to hit 450 (we're doing this on Nov. 2nd). Not bad for a heads and cam car. I was very pleased with the results today. Couldn't believe I left the tires at 23 psi. Whoever said Macs don't flow was crazy! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
The flow numbers are correct. He had them flowed on the same flow bench MMS goes to.

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Verbs I believe they were milled to get ~11.5:1 CR. Vince, yeah I know the flow numbers sound too good to be true, my AAP 5.3 heads flowed 317 @.600" (but my heads were done by their previous guy). My new 6.0's for the 388 however will be done by the same guys as Micah's <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Those are good numbers through the stock rear end. Expect a 12-15rwhp loss if you go to a 12bolt. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Congrats Micah! Wait till you get all that little stuff on and have Mark really tune it! Next time put some more air in the tires on those heavy a$$ 17x11 chrome wheels!! Can't wait to see it on the dyno and at the track on the 2nd!

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq What does AAP stand for? Do they have a website?
What size valves and what is the intake port volume?
Great numbers BTW!

There are not many guys who dyno higher than I did (including you!), so you'll understand if I take your claim with a grain of salt. All I know is with my MMS "stage 2" parts I made 446rwhp and ran 10.87@127mph.

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Hey my car was untuned also. With more tuning I would have hit 470rwhp on the dyno. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq I will have to agree that flow numbers do not always equal HP. Mine only flowed 287cfm peak but they made hella power. Terry do you have a stock rear end also?

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Man, you've gotta love the bench racing! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> What bore were they flowed on? What valve sizes? Were the spark plugs in? Did they use a flow bench? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> We achieved 440 RWHP in a '99 C5 with a 228/228 Comp XE-R and a set of 6.0L heads that flowed 298 cfm. Do you have a flow sheet that you could post up?

Re: Stage 2 Heads/Cam base dyno numbers 436 rwhp/394 rwtq Yes Trevor, I've sadly been reduced to bench racing since my motor blew up, it's not as fun as actual racing, but it gets me by <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> . The valves were 2.08" intake and 1.60" exhaust, the heads were flow matched to the cam. Mark from Andy's is on vacation this week, I will definitely get the flow sheet and post when he is back <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
