Official B58 HPFP Options

sqwinny · 01-07-2022, 12:40 PM

Super random, but is there anything bigger in the works than the spool fx180 or dorch stage 2 at this point? I might be over excited from looking at the dorch + spool overdrive hpfp systems. Goal is to avoid port injection at all costs.

How much power are you looking to make?

It doesn't apply to the b58 but it fits my n20.

Napkin math makes the b58 spool fx180 (b58 1.8**cc) on my n20 max volume flow at 1.56cc (stock HPFP is 0.878cc, current b58tu HPFP on n20 is ~1.084cc but b58 is 1.1**cc) making it limited to around 500whp maybe a little more for my application for full e85.

My goal is 600-650 whp full e85 and that's a really close hard limit as I want to avoid port injection as much as possible.

A 1.900cc or 2.000cc max volume b58 HPFP would meet my needs with some headroom.

You're not going to get in the 600s without port injection. Just run a mix.

Hello everyone,

Should I even bother getting the TU pump and a custom tune for California 91 octane? (more like 89-90 octane) I want to answer No to my own question after reading the thread, but thought it wouldn't hurt to ask. If possible, how much HP and Torque should I be expecting? I would consider E30 down the line but pump gas is just so much more convenient for a daily driver.

Also it seems like nobody has had any real issues with the TU pump yet, so is it the better value at $550 currently compared to Dorch Stage 1 at $1,100?

My current setup is Bm3 Stage 2 ACN 91, xHP stage 3, Agency power intake, CTS charge pipe, ER catted dp, and AWE axle-back. Previous owner did forged pistons with stock compression as well...

No. And the TU pump can be had for even less brand new, but if you're sticking with California 91, the stock HPFP is all you need tbh.

Just a heads up to everyone, got my TU pump from https://euroklasse.com/collections/3...fuel-pump-hpfp

didn't get the extension, just popped the connector off and rotated. 450 seems like a great deal.

Seems almost too good to be true. Is it a trusted website? Doesn't the TU go for around $1K?

They did when they first came out. Now they are on all the new G series, and others, so are cheap.

I should have taken pictures of the pump before installing. Pump looks legit and new so I didn't really question it. Logged my Stg2+ and my fueling looks great. I think they've come down in price, they can be found in the 550 range new now.

Xtiano87 · 01-21-2022, 03:13 PM

Does anyone know if a majority of these pumps are a modified version of another OEM pump? Some of these look like LT4 pumps with different brackets.

MHD has fixed the issue with the Dorch 1/2 mark in the new release. Now I hope there will be no pressure drop on F20 / 30, G30 at E45 and above.

He stated it in his 2nd sentence. Rail pressure drop at higher ethanol blends. BM3 had to make an update to their E50 map as well.

For those wondering, the power difference between your regular Stage 2 and Stage 2+ using 93 Octane can use the below as your guideline. Bottom line --just like all the senior guys here said, not worth it...

B58 Gen1, BM3 OTS map, AA Downpipe, FTP Turbo Inlet Pipe, FTP Charge Pipe, TU Pump, Eisenmann Race Catback and Drop-in intake. There are 2 dyno power pics attached:
* Stage 2 Multimap tune -- 93 Oct vs MPPK
* Stage 2 Multimap vs Stage 2+ Multimap

Only around 10whp difference.. Oh man I wish we have ethanol in my Country.

Skyhigh · 01-24-2022, 12:54 AM

But nearly 45 Nm difference!?
That's not insignificant, although it doesn't seem to last too long.

P.S. you mean MPPSK map

MPPK is 35i.

Have you measured 0-100 with either map?

b7ff · 01-27-2022, 08:39 PM

Ah yes MPPSK - my bad.... Hahaha

Yeah, I saw knock detected in this run during c. 4,000ish RPM; that may be the reason why ECU cut off some power. Have sent my log in the log thread to understand more, but nobody is replying to my logs.. The 45nm difference really isnt what am looking for, am still spinning wheels in 3rd gear rolling with 275 wide tyres.

Nope, havent measured 0-100 yet.. But 100-200km/h easily at around 9 secs; definitely below 10 secs.. I did a run with a Gallardo SuperLeggera 570-4 recently, brake boosting from 2nd gear, leading all the way until I got capitulated at 220km/h -- not bad for a 'grocery getter' 3 series.. hahaha

Looks like decent TQ gains in the mid range though. I have a gen 1 B58, BM3 Stage 2 on 93 oct, AA catted DP and just ordered the TU pump used for cheap on eBay. Figured I'd see how stage 2+ is

Skyhigh · 02-15-2022, 02:39 AM

Share your experience. I have considered it as well for the future but a bit unsure whether it is really worth it on RON98, given also the reduced safety margins.

Stage 1 is an LT1, 2 is an LT4. Lilngenfelter and Nostrum make a "big bore" version (12mm vs 11.5mm plunger, ~10% more flow) that's like $1800 for the pump alone.

LT1 pumps are cheap. Like $170 for a brand new genuine GM part. I'm a cheap bastard (and also a mechanical engineer, so this stuff is fun for me) so I designed a plate to mount it and a lash cap for the plunger end, considering putting together a DIY kit so people can just source their own pumps and plumbing. "Stage 1" for less than the cost of a TU pump?

There's one other thing about these pumps that concerns/interests me, but Stanadyne (the company that designs them) hasn't responded to my questions and these aftermarket setups seem to work despite it so it's probably a non-issue, though Nostrum's pumps do address it. Still trying to figure out how they do it, I may buy a junk pump to do some destructive investigation on
