To go E85 or Bigger Turbos or Both?

[Ryan Shanahan]

Ok, first of all I researched on this forum and everywhere!

I'm looking at upgrading my 2020 Raptor to E85 - seems I need a HPFP and a Tune. Most places are saying either the HPFP or new Fuel Injectors but sounds like the HPFP is the best bet. Anything else might be needed? In Tank Fuel Pump, etc?

I'm also looking at upgrading the Turbos. Full Race is a out of my budget but looks like CR Performance has a good happy medium.

Does anyone know more details or has had positive/negative experiences going E85 and / or upgrading turbos?

Will the stock Transmission, other parts support the E85 and/or Turbo upgrades?

Thanks for all the advice and opinions!

Also, FYI - looks like Brew City Boost has some good setups and options and were very helpful on the phone. I spoke with MPT, Brew City, ZRF Racing and Livernois. All say very slightly different things.

Go with the bigger turbos.

Thanks! Not going to lie, I like the performance the E85 'could' offer but am a little weary on the stock internals. My Raptor is not a daily driver so I'm not 100% sure on how E85 does when just sitting in the tank for a few weeks or so.

I havent heard of a lot of the HO motors cooking, but I don't think many are pushing it either.

Maybe try **** injection as an in-between? I ran **** on my STI and was pretty happy with it. How is E85 availability around you?

Good point...doing my research now (on MPT as I type) on ****. E85 is pretty available around Washington, D.C. However, most places are E50 - E83 so a tune would need to account for that and I assume I'd need another gauge / ethanol reader.

Of course you would need easy access to methanol as well.

I ran 80/20 mix with VP methanol.

The nice thing about Methanol is it is an on demand system, so you only use it when it is triggered at a certain boost level.

I don't want to mislead you though as I cant really speak on **** on these motors as I havent run it myself on the HO motor.

Personally I would go with **** over E85, but I drive a lot.

Go with the bigger turbos.

Larger turbos will produce more power at same PSI and not be as hard on the rods. Not quite sure what the weak links are on these engines but i would assume Rods are up there.

Methanol is very corrosive, and doesn’t like sitting in a tank very long once mixed. We use them on airplane racing engines and have to drain and flush the system after every heat. Amazing gains though

Thanks! That is what I'm reading....mine is not a daily driver. If not just gunning it around town or on the beach - I'll mainly only put 10 miles a day on average. So that's why I'm a little cautious on **** and E85.

Yeah, pure ****, thats why you water it down to 50/50 or 80/20
