The only problem is that when time comes to ask Terry/Steve for help, I wont get as much support than fuel it. So Im actually trying to debate first between PI vs BMS meth. Which one will be better for a long run as a DD.
Is it worth it the double price on PI from meth?


What kind of help are you looking for?

Just trying to see which option will be better/easy to maintain on a DD for me PI or Meth.
Not sure what EOS PI has to offer beside the different design.

Visual inspections and datalogs for both systems would be part of the maintenance. Otherwise with methanol you just fill a tank every now and then.

Methanol is a less intrusive install for sure but methanol for fueling is a band aid.

PI is the right way to go if you need extra fuel capacity.

Methanol should be used solely for cooling and octane bump.

Thanks. Seems a lot of people with PS2 going meth first then ending up on PI. So I guess I will go straight to PI

BMS WMI is here.

I got 4 gallons of boost juice from Summit that is 50/50 mix already. Anyone has difference source or product?

Whats the starting addictive value for PS2 people? The guide said 40 for stock turbo.

If you are mixing E85, the flash will take full advantage of the gas and you will be able to squeeze out all the power while having no timing retard.

I put down 400whp on 91 octane only, no E85 mix or meth or anything like that, with a non updated 91 oct OTS map, and I am AWD.

Since you are mixing E85, you can probably be easily in the 450whp+ range.
What he said. I put down 411whp and 414 wtq straight 93 octane with nothing else with my Pure stage 2 turbo. No tune, just JB4 and with stage 2 LPFP. With E30 (the sweet spot for EWG cars) you might be able to squeeze out a little more. Now, with PI and E60, you are for sure in the 500whp and torque club with FBO of course. A good custom tune will get you those numbers with way less boost!
Only ps2? But why? No intake(to get more air flow), no chargepipe pipe (your going to crack the OEM plastic chargepipe) no aftermarket intercooler(getting hoy air to your engine)

These are my mod and i do 426 WHP with stock turbos

Jb4
Injen intake
ER intercooler
ER chargepipe
Afe catted downpipe
GFB dv+
BMS water methanol injection
MHD flash + BEF
E30 gas

Dont think only in the upgrading turbos or gas pump,
