Excuse my ignorance, but what would be the difference between this stage 1 upgrade kit and something like the dw300? Both have increased ethanol resistance, so is the difference in the amount of fuel that can be flowed?

The DW300C is an "in-tank" LPFP (low pressure fuel pump). This is what was commonly referred to as the fuel pump before direct injection. This pressure is typically around ~40 psi or so.

The IBR stage 1 is an upgrade to the HPFP (high pressure fuel pump) at the engine that is used for direct injection.

The LPFP pumps the fuel from the gas tank and supplies it to the HPFP mounted on the engine at a relatively low fuel pressure. The HPFP increases the fuel pressure to 2,000+ psi to feed the DI injectors. The HPFP increases the fuel pressure mechanically via a cam gear.

Both should be upgraded in order to run E85 with the best flow.

The stock HPFP was the limitation to running straight E85. IBR's stage 1 should also add a bit more pressure and flow to push the stock injectors a bit further to allow for more power. The injectors will be the next fuel bottleneck.

There aren't any aftermarket DI injectors for the FA20 at this time. Auxillary port injection is currently the only option for adding more fuel.

FYI, even the upgraded pump is still going to be a limiter for straight e85. DI cam driven pumps run such high pressure and require tight tolerances so they use fuel as lubricant. Ethanol just isnít as good a lubricant as petrol and eventually the pump internals wear out.

This is still really great news but donít expect to run full e85 on this...

Anyone bite on the pump yet now that it's been released?

Crap, you're right. I checked this morning and it was still in stock.

Guess if you snooze you lose ... Excited for those that got in and can't wait for the feedback coming from the first batch.

IBR had 40 of them in stock and they went on sale at 12:01am. From what I've seen on FB, they were sold out by 12:03. I managed to grab one

I finally threw a HPFP fuel pump code at E70, backed down to E55 and now I'm fine.

Think the Stage 1 rebuild could actually let me run the full E85 my car was tuned on?

I believe IBR said something along the lines of their unit allowing up to e70. Can't recall where tho... Anyways, the upgrade is definitely going to be better than running flex through the stock unit.

I thought that the spill valve sticking was one of the main issues running full ethanol long term.
From the pictures it doesnít appear the IBR kit does anything with that it looks like itís just the pump piston.
Therefore I would not count on this allowing full ethanol, but only time will tell.
It kills me how people line up to be beta testers on stuff like this, better them than me tho

What's the worst that could happen? (sarcasm)

I'm sure the testers have to review some type of disclaimer and sign a 'release of liability'.

Oh I'm completely content with waiting on this, anything is better than Nostrum at this point.

Which reminds me my friend still has to throw his MK6 HPFP prototype through their window since it failed at 5k miles.

i think you can run full e85 if you mix lubricants like lucas

this is exactly why i asked about seeing data on this pump. if its not going to run a full E-85 why even bother. ill be content and either wait till they release a full E-85 hpfp that will probably be in the same $$$ as the nostrum or just get the nostrum.

High pressure DI pumps that can push full e85 do not exist. Check the other DI platforms... Mazda, VW... they've been trying for a decade and still can't do it. It's a mechanical limitation from running a cam driven fuel pump and not grinding the lobes off.

I'd love to be wrong...

According to Cobb the technology does exist, but it's used exclusively by professional race teams and runs ~$6k per pump. Oh, and they aren't for sale to the general public. This is according to Cobb.

according to nostrum: https://www.nostrumshop.com/product/...ure-fuel-pump/ its compatible to e100. idk if this true or not.

My friends failed running E35.... soooooooo.

I hear great things about their GT-R stuff, no idea what supplier they are using for VW/Subaru stuff but they definitely seem to have quality control issues.

Any updates with results on these? Seen a post on Instagram and Facebook, both saying engine failures and problems. Posts have been removed. Any reliable feedback?
