you actually may not see a drop in power as the car won't be going lean anay more it will be hitting it's targets if the car is going lean it puls timing. I would be surprised if you make more power up top.
Thats true, didnt think about that... i will test it out this weekend.

what might make sense to do is drop down to like a e30 mix. do a pull on straight 93 and then add like 4 gallons to the car and see what it does.

For boost on a motor that may be at its build limits E85 is smart since detonation is a risk on pump and can hole or crack a piston or break a ring land or bend a rod. None within 75 miles of me so not a practical choice for a car I drive. I use water meth on my turbo E36M3 and my NA bolt on E90 M3.

true. when i dyno'd at E50 i had a drop off in power after 8k. i assumed it was belt slip (belt was cracked/stretched and since replaced) but it's probably due to me running out of fuel from my smaller blue injectors.

on the same dyno session i had even less power up when i went up to E60+ , most likely due to timing pull. the curve of the power drop off is steeper at E60+ and i lost about 15whp peak power. my AFRs quickly went to 13-14 towards redline according to my p3 gauge (i took a video because the sniffer wasn't working).

right now i'm at E35 and it feels great at 8psi. properstyle is right - it's more important to hit timing targets than to shove a bunch of E85 into the car that the car can't support. you'll probably make more power. i'll redyno sometime at E35 to see if i make full power all the way to redline at 8psi.

Yeah good observation. ill probably stick to just 93 on 10psi, maybe 2/3 gall of e85 in the mix.

I ran a 93/E85 mjx and i cant tell of a difference. If anything its slower. Did another 60-130 and i ran like a 7.2 with a mid -2% grade. Better thAn what u did on full E85. Just doesnt feel quicker. Might have lost tq and gained hp up top.

Currently waiting on TTFS to finalize their inhouse 10psi e85 tune... they are running ID1000 injectors to achieve this. when they get back to me they said they should be able to remote tune me as long as i get the right injectors. will update when i get more info on it.

Well guys, due to the damn near impossibility of running full E85 on this car i might switch over to try and run vp110 when i go on spirited runs. My question is will vp110 run lean like E85 does? Has anyone supercharged try to run that before?

Since you need less volume of gasoline than you need of e85 your injector duty cycle will go down so I believe it will help out with you leaning out. The 110 will prevent the detonation that you would genenerate since you are running high boost. The downsides I see are cost and o2 sensors. Your o2's are not gonna like alot of leaded fuel.

What is your current fuel system setup and are you still planning on changing it?

Im catless but yeah i heard O2's dont like leaded fuel... as far as fuel system i just have the green VF injectors and stock pump. Cant seem to find anyone willing to tune me or just wont get back to me about it. Im hoping to eventually be on full E85 but for now ima try vp110 and see how she does

My Set up
-ESS 650 VT2 (Green Injectors)
-5 Gls ice tank in the trunk
-Armytrix catles exhaust ( very pretty )
-Advanced fuel Dynamics proflex commander.
-BPM Tune for Green injectors.

I had to replace the Blue injectors that came with the kit because I was running out of fuel at E25 now with the Green am Guestimating E33-35 but I still have no logs or Dynos but car runs real Smooth on this blend. I will post my logs and let you guys know how it goes. But am impressed the S65 doesn't Blowup on full E85 and 10 PSI.

Very cool. On the green injectors u will still run out probably past E40/E50. All my dynos are on full E85 no blends so idk for sure the median before it starts running lean.

what injectors are you running? it would be great if any suppliers of upgraded fuel system for this platform would chime in

to my knowledge only gintani has an official fuel system upgrade and RKtunes has one available too just not sure on the specifics.

im running the green vf injectors.

Perfect let's get them to offer the kit! Never the less am stiking to to BPM Sport as my Tunner.

I will log and Dyno the car next week and give you me feed back... there's still hope for the S65 and the E9x platform. "The Last Real M Car"

you will most likely have to swap tuners when it comes time to be able to run full e85. i too am bpm tuned. im running the 620 tune right now. i have a buddy running a vf650 fit with the proflex commander and he is working with rk tunes to be able to run a tune with the flex fuel sensors on. im hoping that becomes a thing. but a fuel system upgrade is inevitable when wanting full e85. for me on 10 psi i will most likely be around 670whp or up.

Even if it's hard to put another pump in the tank(no clue) you could always run an inline pump under the car or if you're cool a surge tank in the truck.
