Is it going to require additional tuning? I think you said you are using a DME that is a one-off type thing.

It was a dream Crystal.. LoL… It was supposed to stay a dream. Do you know how much concrete I would have in my back yard right now!! ![]() Quote:
Yeah riiight! ZHP Cams, and Big Brakes, and it’s pretty much there. Sheesh! ![]() Quote:
It makes sense, make more power by making things more efficient. My 2 Stroke with a carb, made waaay more power with a chamber that was extremely tuned! So, where I luck out is, my E85 ECM is constantly tuning in real-time. It’s a byproduct of the system, because it’s an actual Flex-Fuel system. So if there is E10, E50, E85, E100, etc. it has to tune accordingly. So far the DME has been consistent at throwing timing at the system. So, if the head is running cooler with the ethanol, and the exhaust discharge is creating a cooler environment as well with less heat and pressure, then one can assume the DME will throw more timing. Where the end is at, is anyones guess. One thing I can say is, my boost should be greatly affected in a positive way. My blower will no longer be blowing directly into the cats. This should allow it to produce boost more quickly and efficiently, and may even allow the pressure to rise a minuscule amount. I’ve seen it hit 11lbs before. If it were to get closer to 12lbs, that would be in my opinion the most boost acceptable on stock internals. It’s right there! We will see soon!

The revs in that quick vid, were only to 3800 rpm. I don’t know about feeling anything thing like the P75 as far as power output (only half the engine, LoL). But the sound is bonkers!
