Default 883 AWHP / 832 TQ - Mustang Dyno



2920' Altitude
96*F Ambient
13.13 PSI Ambient

5200 - 33.1 psi - 6.2* of timing - 12.5:1 AFR - 76.2% IDC - 115* IAT
7078 - 30.1 psi - 15* of timing - 13.1:1 AFR - 90.4% IDC - 151* IAT

On this pull I had turned up the fuel pressure from 40 to 48 psi base (upping the effective injector size to 1675cc) after I was about 7% low on fuel at 90-92% IDC. This pull still got lean but by the time it was over 12.8:1 (my personal lift point) the pull was practically over.

On the next pull I went for 56 psi base but lost a fuel pump mid pull. Fuel pressure took a complete nose dive to 16.7:1 AFR at 5188 rpm / 36.2 psi / 86.6% IDC. I guess the Aeromotive 340lph pumps don't like being fed 19.2v from the Kenne Bell boost-a-pump.

BTW...Champion C53VC plugs are awesome for E85.


I've ran them fat at 11.4:1 AFR's at 29 psi and had them up to as high as 38.8 psi and they pull clean as a whistle. They haven't misfired once (which is a feat on E85 with my ignition).

Doesn't look like you can adjust the gap? I plan on running E85 so these might be a good idea.

Those numbers are sick. Congrats!

There is no gap to adjust. The spark goes sideways between the center electrode and the outer ring. They're very resistant to fouling and misfires. F1 cars run surface discharge plugs (but that might be because there isn't much piston to head clearance).

How would a plug like that work on gas? Or is that an e85+ only plug?

Although I didn't notice any differences in idle/cruise I'm not sure that these would be a better option for gas. Best way to find out is to test em I guess!
