The Official Unofficial E85 Ethanol Thread

Does the Stage 2 PR fuel kit require a controller or is it just te Stage 3 that requires a controller?

The walbro 305 pump from PR's stage 2 kit does not need an aftermarket controller and is e85 certified. Only problem is that it doesn't flow that much more compared to stock. The 305 is only good for folks that don't want to need a controller or get a tune for a larger pump like the 450.

I fail to understand the point of the 305 pump.....it would be like going MPI and putting in the stock ROW injectors.

Isn't that the pump they use in the APR kit?

Yes but I believe it is meant to be used in conjuction with MPI.

It is, but their tunes are all pump or race gas for stage 3+. They recommend Sunoco 260 GT which is E10 with stoich at 14.1. I can;t get that at the pump so I'd be running E85 blends. I bet if you asked them if you could run E50+ on a stage3+ kit they'd say no, probably because the 305 can't support it.

Good point.

I forgot that APR hates the best fuel on the planet for street cars.

MPI+LPFP = more fuel

big turbos need more fuel. If you want to run them with E85 you need even more fuel. Depends on your end goals.

Only Eurodyne and United Motorsports (UM) can tune for MPI right now. COBB can do HPFP+LPFP. APR has MPI/LPFP support with their Stage 3+ package.

Several have done that here too, they call it Rec90 though. Ethanol free for boats, RVs etc. That sucks.

I finished about 80% of the PR mpi and lpfp install today. I hope to run full E85 so they better continue to sell the stuff around here dammit.

Found a new station. 14 miles more round trip but can be hit up on the way home from work. $0.60/gallon cheaper too. The withdrawal is real folks.
