Made some Dyno hits on the 98 Cobra. Still making adjustments, but so far so good.

The A/F is very fat until about 5,600 RPM and then it leans out.

Very impressive numbers!

 

[Boosted 03]

20 PSI at 6,400 RPM (Boost was still climbimg)
18 degees max timing at 6,400RPM
IAT's maxed at 94 degrees
A/F ratio was at or below 10.1 until around 5,300 rpm then it climbed to 11.9
Engine compression ratio 9.43:1
DynoJet numbers.


Thanks for the comments guys, she probably would have made much more if I would have wrung it out to 7200 RPM. Did'nt feel the need.

It pulls very hard.:banana:

I think the engines compression ratio and pulley combination helped alot. She makes 400 trq at 3,500! I'll make some more pulls and adjustments once it cools off here. Its near 100 degrees.
