Great info thanks!

That is pretty good for a little Top mount frankly, do you know how rich things ran and how much timing you lost in that heat? Is this on a Front mount or Top mount like MN's? I am trying to get individual feed back on how the stock ECU works, sorry about all the questions, but it sounds like you have a datalogger or loggable aftermarket IAT like the 3 wire GM or AEM units.

One of the nice things about superchargers like that Rotrex is you dont have a turbine side to conduct all that exhaust heat in a tight engine bay.

110-120F IATs will make you more knock prone and cause the ECU to retard timing which takes you away from MBT and is just overall not a good idea on any boosted application.

If you can't afford or don't want the hassle of installing a bigger intercooler or front mounting one... something you can try is active or passive evaporative charge cooling to bring those IATs back down.

Passive is the simpler cheaper way, and is plenty effective and doesn't require a whole lot of effort. You can merely spray water on your IC works great! Just rig a button and use a junkyard washer bottle and nozzle.

Or, ideally inject water/methanol into your charge piping with something like an M3 size nozzle, 150Psi or higher shurflo pump and preferably a progressive controller, though not necessary. Just need a boost reference off the manifold. You tell it to start spraying at like 1-2psi and have it at full spray at 5psi.

The benefits include colder combustion chambers and EGT, denser charge, brings its own oxygen to the party (alcohol) and slight octane bump as well, pure methanol is roughly ~114oct. For the advanced user you could enlist a second smaller (M1-sized) at the compressor inlet. It would be good to have a solenoid immediately inline before the nozzle to stop flow when you want it and keep pressure up through the whole event.

This would also allow the compressor to run more efficiently and produce lower IATs by default.

It is a proven technique used since at least WW2 by fighter pilots on supercharged and turbocharged planes. They called it "wet compression" or pre-compressor injection. It is very easy to do. Just buy a piece of aluminum pipe that will work as a throttle body elbow, weld a nozzle bung in or have a shop do it, and bolt it in. I have used methanol injection on two gas engines and used to use propane injection on the old truck.

I currently have a single M7 (675cc/min @150psi) meth nozzle on my Laser and it allows me to run >2bar on 93oct and a 50/50 mix of water and methanol. There are a few others around here running similar size turbos to mine GT35Rs, HX40s, S362ETs and boosting 35+psi on M10 at throttle body and M3 pre-compressor with pump gas and simlar mixtures.

Couple things to note.. make sure before you attempt to use a greater than 50% concentration of methanol that your pump and lines are compatible. it will eat some types rubber.

Also I made the mistake of using a 1 gallon reservoir, which doesn't last long. Usually every time I fill up the gas tank I fill up the reservoir with a bottle of blue washer fluid, the 50/50 pre-mix which is usually about the same as a gallon of premium.

So not so bad really considering it allows you to always run MBT on whatever chip flash they give you (Hondata?) or it will allow you to pick up some serious power and boost on tunable applications, essentially a race gas ($7-13/gallon) tune for pump prices.
