That's very tasty lookin! Nice, fun lookin curve. Over 300 for about 3700 rpm.

Few questions though...
Was the car tuned at the red line?
How do you like the E85 and what are your idc's?

Well, different fuels like different AFRS. The data for the following is taken from http://en.wikipedia.org/wiki/E85_in_standard_engines under Air Fuel Ratio Comparison. It has a nice chart of some different fuels.

So if this car really was running at 11:1, it would be VERY lean; it would well past a stoichiometric mixture. Or, I imagine that number could scaled to be the gasoline equivalent, resulting something like 11/14.7 * 9.765 = 7.31 actual E85 AFR which is between max power rich and max power lean which makes sense in my mind.

The only person who could really comment is the person who ran the dyno to let us know how that AFR was arrived at.

Just my $.02

Macs Dyno is also very high reading as far as numbers go... I have close to the same exact setup and put down more realistic numbers on a dynamics dyno

MAC is an awesome shop. I was tuned there and then I know atleast 6-8 other guys that drove 6 hours just to have them tune it.

If you ever go back there, as Nick about the guy that moved to Italy named Joseph. His car was a beast.

Yes 7200 rpm is the redline. I love the E85, the engine just seems healthier.

Well thats all a good $.02, but I will do some research and talk to Nick at MAC and find out more about the AFR.

Yea I know its the correction. With a realistic factor you would be more like 270/295.. I know of 2 indentical setups including my own that put down those numbers with correct factors. Very nice numbers though man! e-85 is where it's at

Hahahaha. No, i mean, the red line on the dyno sheet. Was that line with a protune or an ots type map?

I still love the results. Oh, and any info on the IDC's?

IDC's?? Sorry, got to spell it out for me. My bad lol, the red lines on the dyno was completely stock engine management. All it had done was uppipe and 3 inch turboback exhaust.

I did my research today and yes you are correct. It is about 7.31, which if I'm not mistaken, is just a hair rich for E85 according to what I was told. I was told that the stoich for E85 is 9.8:1.

Also, I read that E85 max power rich is about 6.8:1

I thought these numbers looked kinda puffy,... nice curve though.
get it thru the traps and we will see what kind of power it really has
