TTFS/XDI late e-series single HPFP upgrade
- Thread starter Xer0449
- Start date
I was going to update mine later this week to. Tuning is almost dialed in. Car is building 27 psi peak and boost comes on hard at 3600-3800 with the EFR 8374. I went with the bigger pump. Ken at Wedge has been awesome, and Frank has been there to help the whole time once XDI got production and shipping fixed.
Yes, this would be good info.
I'm going to search, but is anyone running this setup with an f87 M2 (TTFS single HPFP, 93 pump gas, pure stage 2, FBO)???
I posted the dyno sheet with all the graphs beginning to end in the first post.
On e30 it made 450/450 whtq on a dynojet. It's currently running on E50 with some more timing. I'll re-dyno it on this setup in a few weeks.
I'm interested in testing full E85 just to see how far we could push the pump, but the car scares me in it's current form

I was curios about only running pump gas.
I'm glad to hear that it scares you!
I'm bored with mine right now, need more fear

Pump gas performance varies greatly depending on your location in the states. In CA, pump gas will always basically be diesel.
In states with good 93 at the pump, you should get much better results.
Best to use ethanol if you have a pump nearby, regardless of your pump gas quality!
HAHA Cali Diesel, I'm glad I don't have that problem. I'm in NJ and have great Shell 93 fuel. I am unable to find ANY E85 in my area though. I really want to keep the car "convenient" for now. So I'll sacrifice some horsepower for convenience. BY that I mean, I'm not going to run a catless DP, or put a huge fuel tank in my trunk.
Hi, I have a BMW M235iX Coupe running pure stage 2 Lpfp and HPFP from TTFS. I live in Maryland so frank has been great with the car. Runs fantastic on 93, going back next week for an e30 tune.
