E85 with a Stillen supercharger?

JWillis72 · 09-24-2014, 11:58 AM

Anyone tried E85 with a Stillen supercharger? If so how did it do? My tuner has been wanting to do a E85 tune on my car and I'm thinking we may do it after the CJM fuel system goes in the car. I tried to search for it but didn't find anything.

You would be the first known one on the forum. I would inquire with stillen maybe if they have done an in house one also possibly.
DMhenderson has a GTM kit and is finishing up an e85 tune on his GTM SC kit currently but still waiting on final results.

You would, I haven't seen that yet

Would you be putting a smaller pulley on to take advantage of the E85? If you can't run more boost I'm not sure how much more you'll get out of it. Do you have enough headroom in your injectors and fuel system?

From what DM has shown the injectors & pump have to get bumped up. I would imagine that increase in HP will be minor, say from 400 to 420 at most, will allow a little extra timing and push everything a bit farther. Squeeze out that last little bit of power.

Then again, I could be wrong and e85 might be an amazing addition to our SC systems and add an additional 50HP by just switching fuels.

I don't think you're going to be wrong. My wild *** guess is that the best part of it for SC, particularly for Stillen guys, is the fact that it burns much cooler. And it would provide a little extra safety margin.

This is mainly my reason for trying it. My injectors are in the 80s so I may not have enough, does E85 take a lot more fuel? I do plan on upgrading the pulley but I'm going to wait for it to come with the upgrade kit from Stillen.

Totally second this.

I used E85 on my 350z stillen, roots blower style, for the sole purpose of the cooling affect, and the little timing advance. If you know anything about that roots stillen setup, people were always crying for more power and we were trying to do anything we could to dig for the extra few ponies. It always fell on its face after 5,200 rpms because it started blowing so hot when we had it maxed out. Not sure of the temps of the centrifugal style stillen on the 370. I have a air temp sensor for sale!

I would say you could get more. How much is the pioneer work you need to do. I think it would be a noticeable gain. But cost per dollar might not be as keen.

You will absolutely need larger injectors or your motor will run lean and....boom.

I have some ID1000's for sale.

Lol.

My car is also the fist CJM fuel system Punk has built for a Stillen supercharger

Oh yeah. If you're even in the neighborhood of maxing out your injectors, budget new ones into the plan. You need what, 30% more E85 than pump gas?

Sweet! Then just drop in some larger injectors and you will be set! What size are you running right now?

30% seems to be the standard. But I was running 1000's on E with 500+to the wheels without a return system.

JWillis72 · 09-24-2014, 12:36 PM

I believe they are 750s. I guess if I need to change the injectors I will most likely wait for the Stillen upgrade kit and do it all at the same time. I was hoping to get away from my Aquamist HFS-3 that has been a pain in the butt.

Chuck33079 · 09-24-2014, 12:37 PM

I seriously doubt 750s will work.
