Just finished the install of my Aquamist HFS-3 in my 04. I am a big fan or methanol and use it for charge cooling on my SC'd BMW. I am lucky enough to live in the same town as the largest distributer of Aquamist products and he agreed to help design and build a kit for my car. Although MI is mainly used on forced induction cars there are benefits to NA also. Cooler intake temps along with secondary fueling are some benefits depending on what percentage of meth is used. Another reason is to have a design and measurements if other V1's are interested in adding MI to their car.
As you can see the tanks are different sizes. This allows the larger tank to act as a sump along with being baffled to prevent sloshing. The low water sensor is in the smaller tank so if you run out of water the sump of the second remains full. This design also takes very little space.
Next step is to clean it all up and send the plate out for powder coating and have the car tuned. The tuning may be some time out while I wait for my cam to be ground.

Definitely a clean setup and install. Not sure that I'd ever go this route unless I had some sort of boost to go along with it. Do you have any ideas what kind of power you'll pick up from the meth injection being N/A?

Just be advised.. If u tune for meth and that pump burps or goes out, your gonna need a new motor. Been there

I am not familiar with the GM ecu and how it uses IAT for timing. I don't think it will be much unless I run higher levels of meth to help with crappy 91 octane. Good thing is I am only in the kit for a minimal amount.

Well aware of the downsides. Aquamist is probably the most reliable kit out.

Very clean setup!

Yup tidy.

This is the shop if anyone was curious.

Jeff makes some rear bad a$$ custom tanks. He has a sweet tank for the V2's that fit in the spare tire well. I plan to keep a spare there so that was out of the question.

Judging by how much my car slows down when it gets above 90° ambient, I would imagine something like this would help on an N/A car at those temperatures.

Im not so sure itll pop an n/a motor as fast as it would on a boosted car. I always have it in the back of my mind but when your playing at higher levels you gotta sacrifice somewhere and anything can happen to any part of the car.

Quality meth kits have safeguards built it that allow them to dump boost if it senses a clog or low flow. The top kits are almost mini computers.

AlkyControl, and run 100% meth

thanks for the pics though!

It would be best to relocate your temperature sensor. The reason meth works on an NA is that it lowers the intake temperature so you can increase timing. It can be just as safe as any other set up if you tune it with a higher base timing, then increase the rate that it pulls timing at higher temperatures to match the regular timing curve. That way when the meth works, you get the extra timing, when it doesn't, you have your standard timing.

No pop then.

to where?

I will also note, Meth changes the AFR. so its not clear cut as just changing timing.

Anywhere after the meth nozzle.

use a GM open element style IAT sensor, cheap and they respond to temp changes quick.

jamesdem1123

what he said^^^

Usually people relocate the sensors closer to the filter to measure the colder air further from the engine and not heat soak the sensor.

The quick response sensor will be able to respond to the actual temperature since it has the open portion that the air flows through.

as far as our cars go..the iat sensor in built into the maf..so it is already right next to the filter.

ideally when running meth you should tune the car for 93..get ur afr's and timing in order..then add meth. adjust ur timing for the extra octane but leave ur fuel tables alone. all this is also determined by how much meth you are spraying and what type of induction the motor is seeing.

I assume I can extend the wires on the IAT relocation harness and put it in the rear of the manifold.

I will add a not that by adding meth, this will lower your AFR you have set in your OL setup when in BE/PE (power enrichment).
lets say I run a single jet of 100% meth (or dual), my 'tuned' AFR target without meth would be 11.8:1 (boosted for example), and then would drop to ~10.2 on the meth.
Its probably 'safer' to leave alone as you state, but its not ideal.

Here is a chart of stoich when using % of gasoline vs meth.

100% gas.......................14.7
90% gas, 10% meth.......13.87
80% gas, 20% meth.......13.04
70% gas, 30% meth.......12.21
60% gas, 40% meth.......11.38
50% gas, 50% meth.......10.55
40% gas, 60% meth.......9.72
30% gas, 70% meth.......8.89
20% gas, 80% meth.......8.06
10% gas, 90% meth.......7.23
100% meth.....................6.4

Yes sir, but me personally would have it at the front of the manifold(or use the EGR return plug)

i hear ya and agree that you will not see the true advantage of using the stuff,but then u become meth dependant...something i refuse to do again.
