bms 100% e85 no meth = :(
so after getting the bms flash i started upping the e85 mix slowly and watching fuel pressure.
i went from 50/50 walbro pump no flash to 65/35 plus flash 75/25 90/10 100 i believe 75% felt the best, after that hpfp started dropping, especially at 100% e85. car runs good but it is not as strong as it was at 75 or below. terry said the fuel looks OK. but i feel like the car is pretty slow now. i know adding meth will help, but is it really worth the upgrade for the gain? has anyone done it? is it that noticeable? i included both logs here. 75 and 100

it was noticeable enough, car run a lot better and sounded different after loading the flash and going 65-75%

I'm sticking with 75% - easy to calculate and my logs look fantastic.

I picked up around 20 whp with meth on top of 100% e85. But, I was also hitting 16.5 deg of timing at 6000 rpm and 20.5 psi at 4000 rpm. If you haven't made tuning corrections to support the change in Ethanol content, then you need to do so before you'll see any benefit of running 100% e85...

Wow, you picked up HP by spraying meth over 100% e85? That is interesting as that doesn't happen on most other platforms. I wonder if it is due to the small FMIC and the meth is cooling the intake charge? E85 won't get to do that much in a DI application like the 335 as compared to most others.

I think the cooling on the IC is the big gain. If you have ever ran meth on this car you would know what I'm talking about as the car just responds well to meth. Things just feel so much smoother when spraying. |

No reason not see some gains on Methanol. The Intake temps drop nearly to ambient. That in turns lowers EGT's even more allowing for more potential ignition and boost accordingly.

It will be interesting with the COBB as I ramp up the car again. Terry set the bar after Shift Sector with a stock turbo car, which I think I already was higher, but I don't have a DynoJet pull to dispute his claim. But 422whp on a mustang is no joke. It really showed in my trap speeds at Shift Sector. |

Without meth you are a bit limited in what you can do. 60-70% E85 is normally suggested instead of 100% E85 for those looking for a max effort as its enough to max out the system and keeps some stress off the fuel system. If you happen to have meth then you'll pickup some addl power from the lower intake temperatures and less IAT based timing reduction. Since you are a manual trans using no lift shift things are a bit different as well compared to say an automatic trans with regard to timing post shift. Overall your map 7 logs using E60+ look fine to me. If you really want more power you're going to need larger turbos.
In terms of what the N54 is capable of stock turbos I think 460rw is really the upper limit. You might be able to run 16.5degrees of advance on a single gear dyno but as soon the transmission shifts the DME is going to drop that down significantly. I'd love to see someone with a log holding 16.5 degrees of advance post shift just to know if its even possible. Mike |

I have been contemplating Walbro or inline.. I think Terry and I are finally satisfied with my setup. 65% mix with flash and Dp's only. You can tell I am in need of an upgraded I/C, however. Here is a JPG log.
