Special thanks to Howard and Rich at Redline Motorsports for a fantastic tune.

How much E did you run and how much meth were you spraying? Also, how did your low side do? Did it keep up good?

I have a single nozzle I believe it's a 15. Car is running 100% pump e85 content was e76. From what I understood the low side was keeping up good but high side was dropping off and couldn't keep up without meth. The car made 11 lbs of boost. I think the fuel is pretty much maxed out without more meth or cam.

The low side hung in pretty good until the end. 100% E85 is quite taxing and we don't typically recommend it. The meth was able to recover what was getting close to being short. Good results, fun car! Enjoy it and thanks for your support!

Because we have seen quite a few of them break the lower ring lands. I like the build a lot. If it was a build in the shop I would have to warn the customer what could happen.

Yep. You need the cam to increase the fuel lobe. That would also be a good time to add your forged pistons.

Really impressive results. Now you are gonna need some new shoes to keep the car from spinning on every pedal smash.

I am right at 600rwp and won't push higher unless internals are swapped out (Course I say that but the SC is ported out to 103 mm sacrilege not to get a bigger throttle body -heheheeee). Extremely happy and confident the engine will hold up. Fun stuff!

That is right at the limit for 93octane on the Lt1 fuel system. Did you upgrade the fuel system or are you adding alky?
