Anyone have any thoughts on running an aquamist with E85 as their primary fuel?

Reason i ask is my car is currently plumbed with an HFS3 which i used to run water/meth with pump. Now that I've switched to TT and E85, i'm contemplating over some ideas on what to do with the system.

These are the setups i'm thinking of in order of preference

Setup1
1. A nozzle after each turbos pre FMIC spraying water
2. No fail safe
3. Progressive spray based on impeller speed

Setup2
1. A nozzle after each turbos pre FMIC spraying water
2. No fail safe
3. Progressive spray based on IDC

Setup3
1. A nozzle after each turbos pre FMIC spraying Water/Meth
2. Fail safe on boost
3. Progressive spray based on IDC
4. Retune to compensate for the octane boost from meth

Setup4
1. Remove it all together

Let me hear your thoughts.

 

Never heard of anyone needing to run meth after switching to E85, so I'd go with setup 4, remove meth all together

 

Yeah, that's why i'm leaning towards option 1 or 2 where i would use distilled water without meth as a heat management rather. The heat directly after the turbo should be high enough to vaporize the water. This in turn offers a more simpler setup since it will not affect the octane in the chamber.

 

Water injection is not a bad idea if you want to expand the exhaust volume but you won't detonate with E85 anyway (and the e85 will cool the combustion chamber and air intake charge).

I would vote #4. Remove and sell and reduce the complexity of your system. I removed my HFS-6 when I switched to a flex fuel set up. I was surprised at how corroded my AN fittings were on the inside! Had to throw all those lines away...

 

I vote plumb two nozzles under your rear bumper and fill with WD-40. Cause reasons.

 

Ill give you a different opinion.

Keep the meth kit. But convert it to run full meth. Like others have said, you're not going to detonate on e85.

Think of it this way, water injection does most of its cooling inside the combustion chamber, during combustion. It cools the flame front. With e85, you can easily push ignition timing well past where it makes peak power. Water would just cause you to need to run even more timing (I don't know of a car that doesn't add more timing when switching to water injection, unless it's a nitrous car, in which case they pull a few degrees, change the plugs, and let er rip).

But, if you put your meth early in the intake stream, you can drop your intake temps a good amount. Yes e85 helps a lot with that anyway, but running cooler intake temps really never hurt anybody. Just don't try to run a ton of meth.

My car has direct port meth injection. I mean, my two seater sitting on stands in a garage that I've never finished. But it's all setup for e85. I look at it as just a bit of extra fuel I can put in and help lower IATs. But it's not ideal...

I recommend not "tuning" on meth. If you don't run a massive hit, you won't need to lean out the tune. Then (assuming you're running speed density), you can allow the ecu to see cooler intake temps and adjust accordingly. There can be some issues with meth pooling on the IAT sensor, so just make sure everything checks out on the dyno. That way if you run out; it doesn't matter. ECU will adjust the tune for a warmer intake charge. Done.

You won't get "as much" out of it, but it becomes a simple setup that you don't need to worry about. And it should help out in case you have any sort of heat soak issues etc etc.

 

Dude why would you tell the internet about the secret to ultra low friction engines. This was supposed to stay on the inside of the carilluminatye circle
