o that explains a lot more, i always thot meth was alternative source for those that didnt want to run race gas/e85.

It is an alternative source. :icon_bigsmurf:

um, I guess you don't understand what it is doing then

when the liquid is vaporized during injection it pulls heat out of the air........among other things

Unless that isn't "cooling" the air charge???

like i said above Auxiliary Injection can "cool" Intake Air Temps, well below ambient air temperature.... whereas even your best and most efficient A2A setup may get close to ambient temp...... never lower obviously

Back with the rotary and the gt42..... when i removed the IC and just ran AI for about a months time it was amazing the difference in boost responce

but why would you want to substitute cooling for an aditive?

because joel just said he didn't want to fit an IC........

and AI alone has some advantages over running both together

there are some hardcore fanatics of AI in the rotary world....with unbelievable results

for instance, on your typical 13b setup with pump gas alone, you are looking at around 15-17psi being your safe ceiling................with a good injection system people are around the area of 25psi on pump gas alone.....all day, every day

I understand the advantages, but why would you want to substitute cooling for an aditive?

Joel, your car is going to be down all winter, its not like you wont have time to make something work. you can make your piping...the way you want it, and an ic isnt that expensive. you can buy a good used one one ebay for cheap.

not only that you dont have to worry about proper applications for your car, you can buy a used side mount and make it work.

Why not use an intercooler along with meth injection?

agreed.

Talk to Jason (Z31) about it. He's running it on the Z he has. But I think he's switching to a FMIC. It may be initially easier to do but it's kind of a pita to have to rely on it all the time. Kinda like nitrous.

Wes, I'm going with Nistune tuning software, E85+Methanol injection, and 9:1 compression pistons for now.

Like Zack said your Intake Air Temps are going to be below your outside air temp and you can go 30% over your fuel injectors for extra fueling. I think the octane rating is 112

and i for one hate intake piping going all over

I'd like to see you get well below ambient IAT's with your A2A IC.........

while having better boost response and a simpler system, without tearing up your front.....

There is an awesome thread I should link to on the club..........

showed a ton of well documented logs (IAT's ect) going from a large FMIC to strictly chemical inection........ showing the results of different mixtures of water and alcohol on IAT's

great results

There is no way i am going to run an IC on my car

not saying A2A IC's are bad or anything, they are a good thing, just not required with a good injection system

its inexpensive, and it works.

you can add to the rice, its safer, and you dont need meth.

i thought meth was used more as an additive, not a cooling system.
