HPFP is a must if you really want to max out the stock turbo on these cars (or meth works too)

Might screw with XDelete for fun and go hit the dyno and real 1/4 mile again. Went 11.4 on dragy, but I want a real world track time. |

I'm one of few thats running MP's updated fuel pump. There's some machining that goes into the process. The new fuel pump sits a bit higher than the previous one did, so it sticks out a small bit. I had issues running into, what I thought was timing being pulled, on MP's stage 2.5 flash on 91. Ran fine with 2 gallons of E. Come to find out this wavy throttle feel was just the car running out of fuel (moderate throttle). Plan is to go with Pure's updated turbo when it becomes available, and mayyybbee run some meth for cooling, and take it from there. I've been able to run 3-5 gallons of E safely and without issue for some time now with MP's new pump. The process went like this: I purchased the pump from BMW Riverside, dropped the car and new pump off at MP. He tuned/logged and modified/installed the pump for a flat fee.

Be patient guys. XDI has their B58 pump in beta testing right now, so it'll drop soon enough. It'll probably be $2300, but it is what it is. I'd love to make 475-480 wheel on the stock turbo with no meth, just E30-E40.

Looking at the logs from my drag runs WGDC is at 87% - 90% over 5000RPM to try to maintain 19PSI boost at the manifold. Charge air temp climbed from 155 F at the tree to 324 F at 19.3PSI/6200RPM in 5th gear (90% WGDC)
CPI/meth injection would help to control the charge air temps, but how much more useful boost do you think we can achieve from the stock turbo? Assuming I'm at about 420 wheel HP, just adding XDI HPFP and full E85 I'm thinking maybe only another 20 - 30 HP max. Not great value for money. Add a bigger turbo and it'd be a different story.

So the meth actually made zero difference in IAT's for me. I have a feeling it's because we're injecting it pre-intercooler.

Bumping this thread. I've been in touch with Tom Wrigley Performance and he said he swapped the B58TU pump into his m240i. All he had to do was extend the wiring. Didnt mention anything about tuning or flashing to compensate for the HPFP. His car is putting down 701rwhp on race gas and meth and about 600rwhp on 93 and meth. He's using a PS2 (I believe he has the hp record).

They look incredibly similar. What's interesting is that the supply line is the same and the rear fuel rail is the same between Gen 1 and TU. The front fuel rail is different, but that's probably because it comes with a fuel pressure sensor. That sensor will need to have a higher threshold than ours to compensate for the pumps higher pressure range.
I'm just digging, so don't take this as the holy grail. But there are a lot of consistencies. The main concern is the hard line going to the fuel rail. Looks like ours has a bend, where the TU one is a straight 90. B58 Gen 1 Pump 13517642466 B58 TU Pump 13518631642

Very interested to see your results given that I have moved on from the CPI kit. I'm just waiting until Spring and hoping to do the HPFP, meth kit and a turbo upgrade.

I see the post on PureTurbos FB page saying they just fitted there PS2 Turbo and the new z4 HPFP (guessing the same as the supra) to a M140i and made 580bhp odd, pump bolted right up with only the wiring needing extended aparently !

We can confirm the Supra pumps are a direct bolt-on with only a wiring extension. We made the swap yesterday morning in about 20 minutes including the wiring extension. We will be offering the Supra pumps as an add on to our upcoming turbo. We will include wire with crimp/solder/seal connectors on both sides and some split loom. Simply snip, strip, and use a heat gun to make the connections.
