Finally got the car to a dyno today, I was very impressed because it was a hot day and I have no custom tuning just the HPP3 and MAFT. The numbers were 412.2 rwhp and 393 rwtq, there was a 1.02 correction factor so the corrected numbers are 420 rwhp and 400 rwtq. I think those are good baseline numbers especially when I'm running crappy 91 octane (California gas)with my 11.6:1 CR <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> . The cam feels very nice and sounds great, I've had almost no problems with the idle and I know the cam will make good power passed my now 6600 rpm rev limiter <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> . I was running rich the whole time, we leaned it out a little with the MAFT but I know this setup can really benefit from custom tuning via LS1 Edit. Oh BTW, mods are in sig and on web page, M6 with stock rear and 4.10's.

Tony,
Congrats on your UNTUNED #'s! It was hot today and the DA wasn't all that good, but those are still good numbers...I can't wait to see what that thing does with some tuning...

Vince, yes we did A-TAP the car, I don't remember the exact numbers of the timing but it could definitely use some more at WOT.

Congats!
Can you post the dyno graph? I'm curious where that lil' cam peaks. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
And do you have any info on the heads, flow numbers, valves, & how much they were milled?

Scott, I will post a copy of the dyno sheet within the next week, I'm moving right now and the scanner is packed up. The flow numbers I received from Andy's Auto Performance on the heads were 317@ .550 intake and 210@ .550 exhaust. I believe the valves are 2.02 intake/1.57 exhaust, for more specific info you may want to page AndysAuto in Western Memebers Forum. The cam was peaking a little lower than we expected according the sheet it peaks at about 6250 rpm. Vince, I will get a copy of the ATAP run for you I just need to get it from Mark @ Andy's.

Also, I don't think that Tony mentioned that these numbers are not corrected and the correction factor I believe was 1.02, so corrected numbers would have been:
420/400
Joe
420/400

I think someone was there with a video camera, I don't know how the sounds quality was though. Joe might be able to get the video on here. Good point I should have posted the corrected numbers since everyone else does anyway, I'll edit my post <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> BTW stock rods and piston, haven't had any valve clearnace issues so far. Jack, we dynoed the car at Dynamic Performance in Lake Forest.

Sounds good. That is right in line with where my car was with the MMS Stage IIx and 229 Cam. Unfortunately it never made it to get tuned...

Looking again at your setup... I am not that far. You have better headers, cutout and some other things.. That would put you about 10rwhp more than me.. Thats about right.. I just wish I knew why my car peaked so soon..
