Yes easily possible but I will say bend has the most comprehensive methodology of tuning this combo and the most experience. I highly recommend them for it.

Without a LPFP you’ll max out at E40-E50, which is plenty good for power. Paul will have no problems.

If you do the LPFP then you can run full E85 but then injectors become the limit again so PI comes after.

Cool thing about trying different parts is that we can share data to see how they fair. I know Ian@Bend did his comparison of the Wagner versus aftermarket TMIC and I'm not 100% certain but I believe that aftermarket cooler is the VSRF one, so I'm optimistic on the Garrett for overall performance due to their time in the industry as a whole.

With that, do any of you gents have logs from any 1/4 times where you may have hot-lapped back to back, or any 60-130 times where you ran a couple within a few minutes of each other? Maybe some dyno pulls where you where logging. Really interested in seeing some other real world examples of how different options fair, regardless of conditions, locations, etc..as I feel the delta would still provide valuable data.

My goal for the car is crack off mid 5 second 60-130's but not require "perfect" conditions. But being the kick-off to summer and hurricane season here in Florida, I'm not expecting peak weather conditions. However, I will still be logging several attempts when I get the car back and the tune is dialed-in, including at least a few back to back at my "spot" where the car will only get a chance to cool down for around 5 minutes +/- as I'm turn around and run it back.

The Bend referenced “sweet spot” car is mine. I dyno’d 706whp and I have probably around 70-80, 60-130 runs. My pb is 5.64. I’m at sea level with decent average temps (much lower than FL). With my new tires I think I might be able to hit 5.5s in colder temps this fall/winter.

I don’t have logs, but I have tons of back to back 60-130. And I’m talking some literally back to back, with just a few seconds in between, and obviously zero cool down. In fact my fastest run ever was the second of back to back runs, which blew my mind. I have a the Wagner and the car is insanely consistent. No issues with install. It does rub slightly on the hood in one corner, but not really an issue.

As far as 60-130, you’re not going to run mid 5s with the Mosslemans and no LPFP. You also won’t hit 700whp.

Interesting. Paul seems to believe it won't be an issue and his take on it is that the EU5'S are the bottle neck not the stock LPFP: see below. Good news, I can see what she does without it on my car and if we hit that bottleneck, I'll simply drop the precision brushless in and call it a day. I was pretty adamant in adding it due to its relatively low price point all things considered but was talked out of it...for now.

From PJT:

Hi Ralph,

Thank you for writing. With your setup, Mosselmans, EU5 Injectors and a Dorch Lift Kit, you do not need an upgraded LPFP. The stock LPFP can flow enough to max out the eu5 injectors.

If you were to upgrade the LPFP, the EU5’s will then become maxed out. You may gain some WHP but probably not enough to feel the difference.

[ralphsmithiii]

It's worth the honorable mention that it's very likely that Ian@Bend is using his tuning wizardry to make the EU5's, Dorch, and Precision work in tandem to produce the results it does without maxing a anything out. In fact, I believe he wrote about it in his blog that's the method to his madness.

It'll be cool to see how it plays out for sure and I'm in communication with Ian as well so I'm covering all my bases 😁

This is also an interesting point to me TopJimmy. I told Paul that I wanted to full pump E85 (flex), not blend down with 93, etc with the Dorch/EU5's/Mosselmans and still he said no LPFP upgrade was needed.

But, I don't want to dwell on it as I'm driving down south tomorrow to get the work done. I may have to tie off with the shop and Paul one more time to make sure we're all on the same page as there seems to be solid conflicting info on what's required to hit my goals without maxing anything out.

That should not be a problem for Paul to limit your power so you can run E85. I was always going for maximum power at certain hardware levels.

So with the lpfp i can obtain full e85 at the 680-700 power level? not trying to mix. nor am i looking to go past 700

That’s what Astris setup is (and mine just with slightly bigger turbos that spool later). And you keep gaining power as you go up in e content, not getting limited on power due to fueling restrictions. Your restriction past this is the rods, dct clutches or manual clutch, or the mosselmans from here. For my car (6MT) my clutch started slipping at E40 when tuning this combo so I upgraded. YMMV.

Yep. 680+ easily and very safely. Full factory knock tables in tact.

IMO if you’re going the turbos/EU5/Dorch/flex route the PR Stage 3 Brushless is a no brainer. It’s one of the cheaper items of the build, completely plug and play, and easy to install.

What turbos you running? I was looking at getting the mosselmans.

Appreciate it, This is the route i'll go because I dont want to deal with extra controllers and the headache of port. What turbos you running?

Astris is running the Mosselmans.

I’m running some pure stage 2 HF’s that strangely spool 800rpm later than they should be lol. But my G35-1050 single kit is on its way so that will change soon.

I made 685/670 DI with only Dorch HPFP + EU5's and stock LPFP on the Pure HF turbos with E85. So it is most definitely possible.

hows the mosselman spool and hows the top end

Were you logging the LPFP pressure to see if it was dropping even slightly during any 60-130 or single gear pulls?

Very possible yes but having extra fuel pressure available is always going to be safer.

**ALERT** XDI has just released their S55 injectors, +110% flow!

Saw that Chet got a set for his single turbo project

Interesting. That graph shows stock n55 injectors outflowing stock s55 injectors? I wonder why bmw would have gone with lower capacity injectors for s55? I wonder if that graph is a typo. Not upset about it if true since I'm n55, lol.

I'll have to find some of the logs, I would be in agreement that upgrading the LPFP would give extra headroom and be safer.

Wonder how these stack up against the new Nostrum Stage 3?
