Just get some more seat time and see if your trap speeds improve. If you have enough fuel to shift at 7300 rpm's, then try that. Just make sure the car isn't too lean at that high rpm. You could also try to find another dyno to put it on to compare, but trap speed is the real indicator of the power a car makes.

I only gained 12whp and 10tq or somthing like that going fast92/92 over my stock intake (LS6) and TB that new era ported. never dynoed form the tb change, but its 7-10 over stock Tb. What did mike saw about the fast gains, I think that right on for the setup.
im not a tuner, but I know is race mode, with a open super hi flow intet setup, and open headers, you can turn the tune up and get some power, but a maf, open cone filter getting hot air, and cats that limits it. Not seeing that it go 120s. When i started going 120s cam only, I was the same whp (395) on the same dyno, But I was probably 800-1000 pounds less weight, with the right slicks/gear, good shocks,hooking.

Hey scotty, I think the gains you got from the intake swap seem pretty good. I know it is over the LS1 manifold but you're still on the stock heads. One day get some good flowing heads on there, with a bump in compression, & it will help out a lot.

Yea, Mike and I talked about how heavy my car is and also the short shifting.He thought I'd crack 400 rwhp.I guess I just set the bar too high for myself with the current set up. My goal is to hit the 11s on the stock 10 bolt if that's even possible. It sounds like I need to ditch the cats to have Mike optimize the tune for peak gains. Too bad the race season is over lol.
I do plan on porting the heads and upgrading the rear to an S60 with 4:30s in the future.

It is lol. I think the low dyno results are a result of the restrictions in the exhaust and intake side. The fast easily outflows the stock 241s and the 1.75 pacesetters and y aren't doing you any favors.
Sending the heads to AI would cost abou a grand to go with their 241 high compression program. Couple that with bigger headers and you'll pick up quite a bit of power. Unfortunately this is one of those situations where bigger bites you in the ***. Not trying to be a dick there lol a smaller cam probably would have performed better given the combo. But at least now you have room to grow. I would save up some cash and do the so program for 1500-1800 you could do heads and pick up some speed egn headers and make 450

I have a **** ton of parts laying around that I need to sell.
Thanks for the I put man.

I'd be happy with the power numbers. I'd say 400+ with stock heads is more the exception than the rule. The torque numbers look low, but that is a big cam and it's definitely carrying the power up top.
The mph does look low, but there are so many factors that can effect that (weather, driving, power curve, etc). I'd try shifting at 7,000 rpm and see how that effects it. Also, probably worth ditching the cats and see if that picks you up any power. Different brands/setups, but I picked up 8 rwhp getting rid of my Dynatech cats and installing off road pipes (heads/cam 2002 Z28).
Biggest thing is to make one change at a time, driving or with the setup, to see what works and what doesn't.
I also agree that ported heads should help out a good amount, especially with that cam. I've heard good things about the A.I. heads as well, and have been thinking about trying out a set on my G8 when I'm ready.
Keep us updated!

Any idea what your race weight is? I just noticed it's convertible.
Also, since your track numbers are from before the intake, you could see a couple tenths and a couple mph without any changes in driving now.

I was told it's good to a little over 500 so I'd say I'm good. I'm determined it's the cats restricting all that built up pressure and also the 3:90's robbing the dyno of some power. I dyno'ed in the spring after the cam install at 389 with stock clutch, 3:42's, pacesetter headers, ory and hooker cat back so that tells me it's the cats...

Highly doubt it's in the cats. If that's what it did before is be checking to make sure everything is inline. Gears will rob a bit but it's not much maybe 5-7whp and then you went to bigger headers which still should have gained over the pacesetters even with cats

I'm planning on modifying the y pipe to be cat less in the spring. I'll post up the new dyno numbers.

You guys are missing it...
This cam should make WELL OVER 450 to the tire, 3.90's or not.
Mike is a VERY reputable tuner, and is extremely familiar with Ed's cams.
You need heads and duals. Bottom line. HEADS AND DUALS.
See what the KPa is at WOT. I bet you need to go speed density with a 4" intake tract and lid as well.
That cam comes ALIVE at 6k RPM.
WHY am I even wasting my breath? Just email Ed Curtis with your set up and and ask HIM why it's doing what it's doing. He made and designed the damn thing.
