Hey, guys! I know it's been a hot minute since I've posted. I believe I made a post a couple months ago on the turbo build, but if you don't remember, here are the basic specs on the car...
Specs:
1997 Cobra
~Stock 97 Cobra 4v B heads, stock upper and lower intake, stock cams.
~2003 Mustang GT shortblock, stock GT pistons, stock GT rods, stock GT crank.
~61mm Precision T4 turbo, custom turbo kit built by Power By The Hour. :rockon:
~38lb/hr Lucas Injectors, 255 in tank and 255 in line fuel pumps, -8 feed -6 return.
~Boost is straight off the wastegate spring, so average of 9.5-10.5psi throughout the run.
~Tuned by Ken Bjonnes :rockon:
I've been itching to get the car converted to E85 since there has slowly been more and more stations carrying close by, so I figured I'd get as much documented as possible since I haven't really seen too may DD/stock motor conversions posted anywhere. We started the day off with getting a baseline pull with gas so there will be similar air temps and boost numbers between gas and E85.
Outdoor air temp: 95*F
Outdoor humidity: 42%
We then swapped the injectors out for a set of High Impedance Siemens Deka 80lb/hr. When Ken originally tuned the car for the turbo with gas and the smaller lucas injectors, he had to adjust the mass air curve for the a/f to be correct (the 38lb injectors are a GM injector and spray less than an actual 38lb injector would). So with that being said, we didn't get a completely accurate gas vs. e85 with the same timing and mass air curve. But with everything corrected, timing added, a/f adjusted to see an average of about 11.8 WOT, this is what the car ended up making:
Same specs as before, but with 80lb injectors, again tuned by Ken Bjonnes.
Outdoor air temp: 95*F
Outdoor humidity: 50%
And here is just a graph of the E85 pull and gas pull together:

I do daily drive this car 50+ miles a day, but Ken is very confident that with this fuel the motor should last more than long enough to get my built short block finished.
