Same motor - just need change injectors and calibration. Utilizing production flex-fuel sensor and have calibration automatically adjust for % ethanol. Would be easy update to Hellfire's engine since sized fuel system to meet flow requirements of E85.

Somewhat reaching limits of how much power can utilize. Haven't reached Mark Donahue definition; "...it will never have enough power until I can spin the wheels at the end of the straightaway in high gear.", but getting close.

Main reason looked into E85 was for PT cooling - extra power was just a bonus. Could easily detune on E85 to same power levels as gas and further reduce thermal load on cooling system.

At end of 15 minute sessions, temps are running below what was tested on dyno - so met targets for cooling system (even on gas). Granted, ambient temps were lower, but extrapolating cooling data to warmer conditions, and engine will be fine.

Might be good winter project - but there is plenty of shopping days left till SEMA.....

As long as the fuel system is up the task. No engine swap should be required. It should be as simple as filling up the tank with E85 and a different calibration for the ECM. Typically E85 requires about 40% more fuel than the same HP on pump gas.

If your going to use E85 make sure you invest in an E85 tester. We have seen pump E85 range from E75-E90.

*Edit - I didn't see Dave's reply because I was slow typing my post, but I'll leave my post here for the tester link.

A lot of local guys run GM flex fuel sensor in conjunction with tuning so the car can automatically swap tables to run between 93 and E85. I believe Holley just released programming and harness to run that sensor as well so I will definitely be on that program. Only prob is two CTS-V pumps will only support ~1200hp on E85...

Also, this car is amazing. Saw it posted on Facebook I believe and came here to go through the thread. Always amazed with your work.

I do need to sort out how to ask people to look with their eyes and not their fingers.

Mark,
I found these molded rubber signs on E-Bay.

I only display them when in the presence of people that "need a reminder". One on the rad support, and one kind of laying on each quarter window outer channel. They are polite, but work. Have thought of having die cut decals made, but no need for me.

Amazing
 

Great job with the build and really enjoyed the videos. Will be great to see the car in person at Vegas and I promise not to touch the car. I think that one of your hallmarks is that in the end the car looks OEM under the hood yet is far from OEM power levels. Fortunately with the way the car looks we can judge the book by it's cover.

Some more track video :)

Awesome! Almost like he was blocking him for a bit, but probably just kept guessing wrong on which to move to get out of Marks way. :lol:

I'll speculate that he didn't want to acknowledge the fact that a '69 Camaro had his far superior Porsche covered in every aspect. Then they start driving over their head in an unpredictable manner and nothing good can happen in that situation. I had a similar situation at T-Hill with a Cayman GTS.

:lol: :thumbsup:

Poor Porsche!
 

Awesome video ... I bet the Porsche driver WON"T post that pass on his thread:ohsnap:
