My NASA Racecar NA Build
#61
Here are some pics during the break in
She is ready to fly, she is still on pump gas so we have the timing pulled way back and running her real rich. Starting the tune on E85 end of next week after we get some more miles on her, anxious to see the numbers!

Havent tuned the car for full power so I couldnt really tell you. We chose the S7R cams over the C8 cams after a 2 hours phone conversation with Jim Wolf himself lol. We told him our goals and what the car was used for. Great guy if you ever get the chance to talk to him.

E85 primarily takes more fuel, many newer fuel systems are alcohol resistant, just not designed to flow 50% more than the OE tune.

Gotcha, it isn't really necessary, just a way to ensure you've got enough fuel at the rail, its more important if you're running high boost (with turbo) or nitrous. Those both have a "shock" draw where the fuel suddenly gets drawn off, and you can get a lean spike.
I'm excited to see what kind of power you make though, this is definitely going to be a pretty awesome set of results.

Update!
We swapped in another tranny for the mean time while we tear my old one apart to further study it. Car is just about ready for this weekend. As far as the final tune went, she put down 292whp, 246tq on the E85. We are having the power fall off around 6800, which in our opinion is a little early especially with the cams/head work we have gone with. Once we get through this weekend, we are going to throw her back on the dyno after the motor loosens up a bit. We dont see why we cant break into the 300-310 area on a mustang dyno, which would be about 330-340whp on a dynojet for those concerned with higher numbers. The tune is pretty conservative since the motor is built to last for at least 2 years of road racing and time trials. For their first NA build, with a haltech, on E85, I give mad props to the guys at Japtrix. We still have alot of tweaking and work to do so its only up from here! I will make a new post with her performance this weekend at Homestead Speedway!
