PORT INJ who what when and why

What upgrade?

on my ST 5862 setup, with just an upgraded LPFP on an E35-E40 blend I started running out of fuel at the 3500-5500 range on 29-30psi.

Are you still currently tuning? Where did you end up at with power (if dynoed)

Still tuning as I just recently switched to the boost box. Should hit the dyno here in the next month or two. I'd assume on just the E30-E40 mix and 27-28psi I would hope to be around 600-625whp. Once I get my port meth system running we will see where that can carry more.

What port meth system are you planning on using? With the recent discovery of guys using E85 PI systems for meth I'm not more and more intrigued in going that direction! You must be in the same boat as me with access to E85 just not easy access

Exactly, the closest E85 to me is about 2.5 hours away. I have a stock intake manifold that was modified by @Jason@Propulsive-Dynamics with aquamist jets. It makes a hell of a difference both on pump and my E30 mix.

Nice.. I can stay on E40 for around 6 months using about 85 gallons I put in two drums..
I'd like to try to go port with a controller using a PI set up and just feed the rail with meth not a T'ed in fuel line.. I'm pretty sure I'd have to increase the line size for shear volume alone. Gonna gather more info then make a decision

This is another thing about e93 that sucks. No clean, meth installation space.

Yea no space back there at alllllll

I'd definitely run meth if I had the trunk space. I don't and I am not that interested in fabbing up a small custom tank that will require frequent filling, etc. I'll just drive 5 mins to the e85 pump when I want to go fast after I get this flex fuel on.

If you took apart some of the panels in the LR you might be able to get something of decent size back there.. I'm sorry I just hate convertibles.. They are all techs nemesis! They make lots of noise! They leak water! Wind noises and they are always annoying to work on

LR? Left Rear?

Initially I had dreamt up a driver side, opposite windshield washer tank, fabbed meth tank. But I was convinced not to to do this even in non-flammable concentrations. I figure, its all but a 2 foot long feed line.

If I had another chassis, I'd stick my tank where the hard top hydraulics go. I saw advan makes a tank that fits there:

you know how big this tank is and pricing?

No, and I think its a lot.
