I'm doing a "Stage 1" E85 tune with F80Paul. Stock everything, just tune and hpfp. That was my goal with the car from the get go. I don't want to do a huge build that requires a bunch of supporting mods. I just don't like feeling like I'm leaving efficiency on the table.
E30 was a nice bump compared to 93, so I expect the E85 bump to be substantial. I'm about $1k in for the upgrade (BF Custom tune pricing + used pump + install myself) and then got a 550i clutch on standby. IMO, not bad for a setup that *should* be capable of 500whp. Honestly we're spoiled. Think about previous engines that needed intercoolers, charge pipes, lpfp, etc. just to hit mid 400s. |

yes, e85 with very high ignition timing and maxxed out stock turbo at ~1.4bar should give ~500hp imho. these engines love timing so much, so e85 should be great.

B58 needs timing to get nice power and with 11.0:1 compression this means you need high octane fuel. On bad fuel no matter how much you turn up the boost, power will stay same or even get worse if timing gets very low. |

They were on national backorder well before people knew they were a bolt-on upgrade. We ordered one for our test car with no clue if it would work, just hoping it would. This was a month or so before the car arrived, even at that point, my supplier said there was one in the country. We ended up with it, then we ended up with the last 4 in the country, and now have 9 more coming.

Hey IK6SPEED your pms are full so I can't respond. But feel free to put me on blast and call out my mistake instead of constantly private messaging me the same bullshit.
He is very adamant that we be explicit in whether we are talking about pumps from a Supra or other B58 model. Not sure why he feels like constantly messaging me since I never said I bought a pump from a Supra, but here's your opportunity to call me out on my bluff. |

It looks like the M340i/Z4 do not use the same updated pump as the Supra, I made a edit under the HDP6 Pump section. Quote:

I reached out to Spec (great customer service) and their clutches for our cars all mat up to the stock DMFW. I think that quells most of my concerns about going aftermarket and being forced into a SMFW with drivetrain chatter. I think I'll be heading the Stage 2+ route as the clutch slips are getting more common. |

Update On Dorch Engineering Stage 1
Just got done installing the DE Stage 1 HPFP, so far i'm on my first revision of my E50 tune and the results are looking promising. Where I used to get a hard dip in rail pressure (3000-4000RPM) I am now going over the rail target. View post on imgur.com Logs: Wedge E50 V1 3rd Gear (Dorch HPFP) Wedge E50 V1 4th Gear (Dorch HPFP)

Couple of questions: 1. Why is your rail target 2600 PSI vs stock at 2900 PSI? 2. Are you going to shoot for higher boost as well as higher E content? Current boost levels look similar to MHD Stage 2 95_102 OTS I'm hitting about 19 - 20PSI at 5500 - 6000 RPM with a Load Target of 180 and similar WGDC of 92%. Your Load Target is 200 but Load Actual drops off from about 6000 RPM and the gap between target and actual increases. Is this because the stock turbo is out of it's efficiency range?

It'll be changed back to 2900psi, it's something my tuner did back when I was running E30 on stock HPFP. We noticed when we dropped the rail pressure down a bit it actually didn't dip as hard. Doesn't make a lot of sense, but it solved some misfire issues. Quote:

If anyone wants to purchase my VTT Supra pump - it'll be here today or Monday.
I went Dorch Stage 2, because why the heck not. More expensive, but I'm only doing this once. I think it's a great product depending on what power level you are going for. I'm still using the VTT GC Turbo (that will arrive in Feb-March). I am keeping my Meth. I'm super pumped to be a part of this with everyone who has been in the mix on these B58 mods (Solid, SC_B58x, Kern etc...)...I feel like we need a national meet-up hahaha |
