Hi
I totally removed the intercooler and now rely on methanol/water injection for cooling
Bankai
After a blast on a 22c day the log temps are hitting 90c, OK it was a hot day but jeez..
MR2 Log, no intercooler, post compressor WI - YouTube
This is with an Aquamist 1c system (basic boost triggered pump) with a 0.7 and 0.5 injector post compressor
I thought I would try adding moar warta.
After looking around at the available kits I found the Devils-Own kits to be the best for price and atomisation.
Twin tanks in the boot, separate one for each kit
The Devils injector will be placed looking into the "eye" of the turbo as close to the impeller as possible, doing this is not easy....the best position on offer is firing the injector from the wall of the hose so I adapted some mesh to give me the optimum position, lets hope it stays in place and does not offer too much restriction :shock:
the injector is just spraying pure water at the moment and hopefully will help lower temps a bit closer to 30c, this injector should flow circa 400cc per min
From reading up this position changes quite a few things...the compressor map can be shifted allowing more power at higher RPM, the turbo becomes more isothermic, the speed of sound in the gas and the mach number of the compressor blade tips should also change....interesting stuff eh?
Air filter in position
After a test drive in cooler ambient conditions than the last logged run the inlet temp has dropped by circa 40c
MR2 Log, no intercooler, pre+post compressor WI - YouTube
Ambient temp was 16c, injection trigger point for the Aquamist system was dropped to 4psi, Devils system was triggered at 2psi and ramps up to max flow at 19psi (boost sensitive progressive system)
Boost temps were seen to be around 40c, I never saw 50c on the test
I will try for a slightly larger injector soon for lower temps, remove the Aquamist system (as it's atomisation leaves a lot to be desired) and go twin injector on the devil kit for pre and post turbo injection.
