I don't think you're too lean. Your just ok.

You don't have a turbo aplication car so the air/fuel ration wont change due to a forced induction.

You're fine!
Nice numbers BTW!

Didn't they come with 270hp out of the box? I know that's 224 at the wheels, but that seems low. What am I missing?
the v6 has 190-200 in the engine, it doesn't put those numbers down at the wheels. Its kinda misleading when a car comes out and they say its got 500 hp. But that's before the drive train gets to it first.

Drivetrain losses are about 15% for FWD, 17% for RWD. I don't know, but I assume it's a tad bit higher for AWD, so that result is very much in line (17%).

A good rule of thumb which I was given for drivetrain loss is:
15-18% for a manual fwd
18 - 22% for an automatic fwd
22 - 25% for auto w/ all wheel drive

So, taking the OP's numbers of 224 whp and correcting by 25% gives 298.7 hp at the crank. This seems to be in line with what others have achieved using a good exhaust, intake and tuning (a little more than 10% over stock). Sounds like a fun car. :thumbup:

Want to get mine on a dyno, but with 150,000 miles I think many of the horses will have died along the way......if mine puts out figs like yours I'd be more than happy:thumbup:

I'd still like to see somebody run the GIAC "Race" file on 100 octane.
I've got the file, but 100 octane is scarce down here (was easy to find in MN - one of the few benefits of snowmobile country), and I really don't have the money these days.

We must be lucky in the UK because most filling stations have 99 Octane fuel and it's only 7p (about 10c) more per litre than the standard 95 rated stuff. There are also some stations with 102 octane race fuel:thumbup:

13 gallons 92 octane + 7 gallons toluene or xylene = 100 octane. --> (13(92) + 7(115)) / 20 = 100.05 octane

Your car will run like a CHAMP. :thumbup:

Well your new intake manifold adds at LEAST 25 hp! :thumbup:
