Pistons are 8:1, but my static is slightly higher from decking on block and head.
My egt's are always cool because I keep the timing as early as possible so it is cooler by the time the ex valve opens.
I did run the latest timing I have EVER run on the 944 today, however because I believe the powemist burns as fast or faster than the tolene blend.
It is still my contention that the MLS steel gasket gives lateral support to the alusil sleeves when torqued.
My head flows 243 cfm @28in/hg@.5" on the intake.
My exhaust flow is very, very good now for a turbo head.
I would put my exhaust flow against any turbo head in the world that retains the ceramic.

Coming from the other thread, if you have another get-together (from the sound of it), I would come up if I'm free and invited. I'm never in the 951 corner, maybe I'll have to look more often.

Why have you not raised the compression even higher for more area under the curve? You won't have to run as much boost, and thus you'll have a greater temperature differential when the air enters the plenum, which will give you the power you want and also help suppress detonation.
Raise the CR to help suppress Detonation, LOL
Congrats Tool, now go get yourself a proper Boost controller

That is a horrendous powerband for a "street car". If you didn't "market" this engine as a street engine I wouldn't be so harsh, but a street engine should not start making power at 5000rpm. A bolt on Turbo S has a better curve from 0 to 5000 rpm. Thats huge considering this setup only offers superiority for 2200 rpms. In fact, at 4000, most are over 300 ft lbs to the wheels, 100 ft. lbs higher than your current powerplant configuration.

tommo, just out of curiosity have you ever had yours dyno'd? I'm wondering what you came up with having similar mod's to mine. PM me if you'd rather.
