Tony,

Peak boost was 15.4 psi. At redline it had fallen to 11.2 psi. Peak HP was made @5300rpm @12.9 psi

Yes, stock exhaust system with except for some sort of aftermarket header (don't remember the brand). On many of the 951's I dynoed there were boost leaks from all the joints and it is very hard to notice the leak when road testing. On the dyno it is more obviously easier to see what is going on under the hood on full blast and if you know what to listen for it is a dead give away.

I don't doubt that you know all of this already however.

Very nice chart. I'm impressed with the 72 lb chipset. I can't wait to get on the dyno myself to test it out.

I managed 247/314 out of my AA-chipped car @ 17psi with a gutted cat. What makes the V-chips so much better? Just curious, maybe in the market for a 951 again shortly...the last car was just too rough & was sold as a track car. But hey! $1800 for a running 951!

Only the 951 S came with a 26/8. All other 88 non S Turbos, like mine, came with K26/6's.

It's extremely rare to see a 5 liter put out 600HP and requires quite a bit of money and rpm to do it. 600ft tq would be much harder to do.
No. It is the equivalent of a normally aspirated 302 putting down 300TQ to the wheels. The 302 can do that easily. You are correct you will rarely see a 600HP/TQ NA 302 but that doesn't apply here. Check out your comparison below.

Correct. A 302 with AFR heads and stock cam will put out 300+ flywheel HP/TQ. He is well within the realm of achievable HP.

Jesse,

Those are some sweet numbers. I am really going to have to check out the MAF setup and meet up at some point. I can't make the meet on Feb. 4th because I'm going snowboarding. Hope you guys have a good time and good luck with the future mods!

I was really wondering about that 600lb/ft statement, and trying to wrap my head around how that could be possible....

Nice chart! I wish my 951 made that much power...
