This is your motor? If so can't wait to see the results
That's Phil's personal motor.
I wish this was my motor. No, Phil just finished mine. Mine's an anemic little M6 C5 that runs around with only 460-470 RWHP. I just wanted something for running out to the grocery store, etc. Phil'S getting a set of 3.90's for me which should help it a little. Phil's tuning is second to none.

I like your set-up from the intake down. What couplers did you use? Did you custom build the ducting? Will it hook directly into a vararam? The colors look great with the valve covers and intake.

Good luck with it.
We used Hose Techniques 4" hose, used 4" aluminum U-bends and I tig welded it. Its going to bolt right to the Vararam and eliminate the need for the bottleneck MAF. Thanks! Eventually we're going to have a set of custom sheet metal valve covers made for both motors.

Phil, you're running the car in speed density without a MAF?
Guy,
Whats funny, we fired up Sam's car and after it warmed up we noticed that the LTFT weren't cycling. It was an old SD program. We're definitely going without the MAF and speed density 100%.

so the CR you are running does not require you to run race fuel?
Running higher octane is a requirement of dynamic compression and not that of static compression. The size of the cam on intake duration and lobe separation angle dictates where the intake valve closes while the picton is rising on the compression stroke. If the intake valve isn't yet closed while the piston is comming up then it doesn't start to build compression since the cylinder isn't sealed. The bigger the cam, the later the intake valve closes.
The compression then isnt a fuction of displacement then (static compression) but rather the displacement starting from the point the intake valve closes relative to the piston's position. Static compression such as his 12.3:1 is what it would be if the piston was building compression from the bottom of the cylinder and the intake valve was closed while in that position which is never the case.

You hit the nail on the head. Its not SCR that determines if a car will run on pump fuel its DCR. Our DCR is in the mid to low 9s where our old motor was low 9s.

With the way phil drives I see his car going deep low 10's maybe a high 9's with this new N/A setup. Who knows where it will go with the direct port nitrous shot.
