Port Injector or HPFP Overdrive?

mikeyoooooo · 09-04-2021, 07:14 PM

My turbos are starting to go and was looking to upgrade to RB Two Plus turbos and would like to run full e85. Which is the better method nowadays for full e85? PI or HPFP overdrive?

PI has been well proven on this platform. That would be my choice once I go with 19t’s on my e90

I was going to get the PFS pod, but I ended up with the BMP port injection. Port just seems to be more common on this platform. I'm running this setup with the RB Game Finisher turbos and the BMP Stage 3 low pressure pump on full E85 + 50/50 Meth with dual BM5 nozzles just for more IAT cooling purposes.

Over driving the high pressure pump has caused chain sprocket issues.
I would stay the hell away from this.
PI is the best option by far.

Looks like the consensus is port injection. Thanks will be going that route

Yeah go with PI.

Overspinning the already somewhat weak HPFP is not the greatest idea more like a band aid. Maybe if you bought a BNIB HPFP from FCP but then you have spent a lot more than PI and will still be limited in the power you can make on full E85 because of the DI limits.
