So I've been doing lots of research on this but can't seem to find an answer.

I'm planning on picking up the Dorch Stage 2 hpfp this week and want to get a full e85 tune. Currently on stock turbos but have all the supporting mods done i.e. catless dp, full exhaust, intake. (Planning to get bigger turbos down the line but not atm)

What kind of whp numbers should I expect from this? Reached out to different tuners but they're not seeming to respond back so

Got a few buddies telling me it should easily be over 500whp but currently coming from an mhd stage 2 map running like 390whp, I'm a bit skeptical. Any feedback would be appreciated.

You should get about the same as with the MHD Stage 2+HPFP E30 map, somewhere around 500 WHP on E40 - E85

I don't think a custom tune will do much more with the stock turbo

Hm I see. I just didn't want to go through the hassle of mixing e85 with pump gas. Seems like a headache to me to try and get real close to E30.

You don't need to get real close. I'm currently running E42 with the MHD Stage 2+HPFP OTS tune with Dorch Stage 2 HPFP and making 509WHP 100-200 km/h in 7.0s. For a while I even ran E30 on the MHD 95 octane petrol tune with stock HPFP, also no problems and all logging variables looked good.

As long as your pump E85 is consistently E80 - E85 a 50/50 mix gets you between E40 and E42. Even if the E85 pump goes down to E60 in winter and you mix 50/50 you'll still end up at minimum E30.

It's been proven that 90% of the benefits of ethanol in SI DI petrol engines are realised by E40 (charge cooling and anti-knock) Increasing ethanol % further only provides marginal benefit with poorer tank range/mpg and harder cold weather starting.

I think you could also safely run straight E85 with the E30 OTS tunes, stock turbo and Dorch Stage 2 HPFP if you want to.

Oz seems Dorch is much better than "supra" pump due to whp!

I get approx 460 in your dyno, so another 40-50 would be welcome

This ethanol is like gold..

Just doing a 50/50 mix at the pump seems like a lot less headache than trying to achieve ~E30 every time. Thanks for the insight on this

If you really want to get the most out of the Gen 1 B58 stock turbo, you will need to run WMI in addition to an E blend. I'm in the same situation as you as I have a Dorch Stg 2 and am running BM3 Stg 2+. In addition, I have paid for a custom tune with F80Paul when I was trying to run full E85 with a CPI kit. I decided to skip on the CPI and got the HPFP upgrade instead.

Now I'm on the fence about getting a custom tune with the stock turbo or waiting until I get a turbo upgrade. Most of Paul's customers usually get a custom E50 tune. I asked him if there was any reason to go above E50 and he said E70 would be the cut off. He states that he usually can get 2 degree more timing. As others have mentioned, running full E85 is just a convenience thing so that you dont have to measure at the pump or if you fill up at your house through jugs/drums.

So currently I'm detriming if I want to do an E70 + 100% Meth custom tune or just hold off until I get a VTT GC+.

Hi,
How much boost would be the most out of the Gen 1 B58 stock turbo? Is not in the max with stage 2+ with BM3 or MHD??

Guessing on DR's you can pull a 3.7 0-100 on a prepped track, so 10.7 ish 0-200. Should be able to get into the 10's in the quarter!

Booked in for Test'N'Tune at Queensland Raceway next Saturday.

Fingers crossed for a good 60ft

I'm on the same boat. Currently running BM3 Stage2+ with Dorch Stage 2 pump and supporting mods (catless DP, Intake).

Reached out to a tuner to get a full E85 map, he mentioned the pump may not be enough to get the most of the stock turbo as there is an injector size limit too.

On running mixes, are you guys using an ethanol content sensor? I've been looking at the fuel-it kits. The one for the F30 needs to be installed under the car which I'd really like to avoid. I'm trying to see if the Supra kit can work with the fuel line that came with the Dorch HPFP.

Lol which tuner told you the Dorch Stg 2 isnt enough for full E85 on the stock turbo? Our injectors are perfectly fine even at 700-800whp with a proper HPFP, LPFP and port injection.

I have the Fuel It kit on my car and its been working fine for over a year now. However, its on the pricey side and you can get an ECA for way cheaper like Spool or putting one together yourself.

I've been running full E85 for 4 months now on the TU pump. It works well, but a Dorch stage 2 will get you more midrange. My boost is limited 3k-5k to work around the pumps limits, where the Dorch Stage 2 should be able to take full advantage of all the boost you can run.

The keyword there is port injection, which requires a separate controller. I'd prefer to control things at one place with a custom flash.

Port injection is only needed when you are going 700whp and above. The Dorch Stg 2 can handle full E85 on the stock turbo, so again I would like to know which tuner told you otherwise because they are wrong.

[AWD_Maniac]

He said we'll make more power on E50 and the pump can support E85 but we'd have to limit power.

I'm working with Jeff Payn. He has more experience on Ecutek and Supras. Is the Supra stock turbo bigger than ours? That may explain his reasoning.

The supras don't have the upgraded hpfp options we do. He may be referring to the TU pump.

Hey mate, it's been a little while between posts.

I'm looking at Supra TU or possibly Dorsch stg1 pump. Would either be able to do a 50/50 mix (because thats so much easier!) do you reckon? I mean i'd err on the TU side for OEM durability, but also would prefer a little headroom if that's possible. BM3 and would run a stage 2+ E30 OTS tune. Would likely only run it at test n tune events as ive previously run E15ish to clear up my BM3 91 Stg2 logs and the economy drops off a cliff when running E mix fuels.

[Rehverze]

Did anyone ever find an accurate answer for this? I'm tempted to get a custom E85 tune until I decide on a turbo upgrade.

I looked at the DE ECA Kit no experience with it but write up says no under car work required. Real time map adjustment depending whats in your tank from straight 93 oct to full E85 and anything in between. Dynamically adjusts your BM3 or MHD maps to accommodate what's flowing thru the fuel lines at that point in time. am def no expert but that sounds like best of all worlds to me?

I know it's the thought that counts, but considering this thread is three years old, and OP has since sold his B58....
