Anyone running Non Intercooled EFI turbo setup on e85

[svrdram]

I'm seriously interested in this discussion as well. Building a 408w powered mustang street car with a pair of 6766's on e85. I've been on the fence on wether or not to run a A/w setup or injection.

Does this seem doable without intercooler?
Yes, without a doubt. There is a guy with a drag boat (Mark55) that has made 1800hp on pump E85 and never had issues. Just make sure to run a cold plug to start (NGK 9 or 10.) Pull out the timing and then slowly sneek back up on it.The tuning window is huge so don't focus so much on leaning it out......try to run a rich A/F, like 10.0:1....since the benefit or E85 is the amount/temperature and then slowly add back in timing.

What EFI system are you using?

The car has to be able to run 5.40s or quicker 1/8th miles at 3300lbs with intercooler or 3150lbs without

The car has to be able to run 5.40s or quicker 1/8th miles at 3300lbs with intercooler or 3150lbs without. My current setup is with an Air-to-water with 160lb injectors with 8-10 psi running 6.00s in the 1/8 at 115-120 mph with 110 octane fuel. Can push it to 25 psi With current fuel and should take me from the 700hp range at now to the 1000+ range but if can ditch the intercooler I can drop 150lbs on the car in the class rules so will help out a great deal. If nothing else if keep the intercooler how much hp and tq gain is it to go to E85 roughly if know. Thanks!

Just called Wolf Racing and they said they have never run E85 in their turbo car. Methanol is what they run with no intercooler. No intercooler was not recomended at high boost but they do not have experience with E85 so no real recommendations on it.

talking about ethanol.

even, if your losing 20-50hp it might be worth considering, but anything more than that, i don't know.

interested to see just how much of a change it makes with and without.

Sorry just seen the Meth monster in your sig, so wasn't sure if you were talking meth or ethanol! I think a air to air with short piping is the way to go not much wieght and drop the IAT pre injectors.

all good, the brothers car runs on E85 i shoulda put that in.

we were thinking possibly just for racing, bypass the I/C and go direct saves 20ft of pipework but, if it's going to drop 50hp or so it wouldn't be the effort really. if it stayed the same power or only lost a little it's definitely something worth doing.

less pipework should see it at least spool slightly faster and have a better throttle response.

Bump...
I have tight space on my new build and am thinking of ditching the air to water intercooler. Not having to chase ice down, draining/filling, and the extra weight would be a plus. Car will be running E85, BS3 and around 25# - 30#. Thinking of running methanol on the inlet pipe, but then started thinking why not pull out a couple pounds of boost and run a 50 shot of nitrous. Should provide plenty of cooling and jump the tq up. Thoughts?

Mark55 is only guy I know that ran with and without an A/W IC on his BBC Twin Turbo Drag Boat. He would be the best person to contact about this.

I can only speak in terms of my car.....which is most street car..but I run a 418 with an mid sized 88mm S400 and it makes great power. In a 3500lb car it runs just shy of 150mph on a 17" tire only seeing 20PSI. The inlets are freaking as it pegs the IAT sensor at 255 within 2 seconds of WOT.

This was my 3rd season running the car with no IC on E85 and have had no issues.

That inlet temp would bother me, especially when making around 1200rwhp.

I am up in the air on this one. I would think a wet 50 shot would work good, nitrous exits the bottle around -140*, and being wet with E85 would cool it even more.

It will take more than a 50 shot to get air temps cooled down!!! Now on a 50 shot the car will pick up but from what we have seen it takes 150-200 worth of nitrous to get the air temps to come down........ Good luck....

you cant really go by what the iat sensor is reading on a efi setup.. the sensor is before the air is seeing the e85.. measure that air temp at the intake valve where its getting mixed with e85 and i bet its alot lower than what the sensor is seeing..

Great point. I have always said who cares wat IAT shows...what is the combustion temp showing....I'm gonna do EGT's soon to try to understand what is going on.

So you guys think a methanol kit would have a better cooling affect then nitrous?
