I agree with pretty much everything you've cited here! I have a few places where I can play and may even be able to reach my number without changing cams which, secretly, is one of my goals. Here's how:
E85 - Injectors are cheap and the stock rail can handle the additional fluid required to feed an E85 engine. I am already required to use a fuel cell and aftermarket pump, so that is already figured into the budget. I used E85 on my last Pikes Peak car and it works incredibly well (8-10%+). Octane through the roof, burns much cooler, which is a must at Pikes Peak, and has the added benefit of being about $10.00 per gallon less than race fuel!
Open Exhaust. I will use the stock header, at first, but fabricate a straight pipe exhaust all the way out the back. I'm not limited on noise. Some places where I test may have restrictions, but a high flow resonator will get me within regs. As sponsorship or other funding allows, I will design and build a 4 into 1 long tube step header with a high velocity collector. Definitely wrapping the system. That was something else we proved on the previous car.
A re-flash of the stock ECU will definitely accompany all changes, and will be the trickiest part of this. If I can avoid the expense of a new ECU, that would be best. It's one area where I used to have sponsorship, but no longer.
I was really curious what we might be able to expect from this engine and when I came across your thread it really gave me hope that we could reach our goal number without breaking the bank.
Thanks again for the most impressive work!
