There is a limited amount of information on recent meth/water injection installs on Supercharged 95-97 OBDII 80 series so I thought I would post up our* install. (*Thanks to Toyota Master Technician John G for the valuable assistance!)
When I installed the TRD Supercharger installed here in Arizona about 7 years ago, my first goal (by necessity) was to keep coolant temperatures under control. After restoring my cooling system to 100% effectiveness, several mods followed: JDM electric fan, heavily juiced black hub fan clutch, hood vents, 3F fan assembly, foam along top of radiator gap, and relocating driving lights that were blocking the front of the grill. The goal was to keep it drivable in any summer situation including towing, etc. I am satisfied with the engine cooling performance, so now...
…The next goal is working on getting intake temperatures down so that when I need the power from the supercharger, I’m not restricted due to the hot intake temps. Of course when I really need it here in AZ is when I’m either towing or loaded down for a camping / wheeling trip and working through multiple long mountain passes. These types of situations where the engine is working hard is when the intake temps really climb.
But that is when I need the power...
My expectations are to reclaim the power the S/C is capable of in those situations where I need it. I don’t plan on having a “fast” truck or running around town like a tuner blasting away from stop lights. The truck is heavy and has a straight six for goodness sake. I expect to drive around town and not have the injection activate in normal day to day driving – except maybe when getting on the freeway. I can get a little better performance in this day to day type driving just by being able to advance my base timing – which I will play with after the install and report my findings.
An intercooler would be ideal but without a proven one out there on the market, I’ve turned to Methanol-water injection. I’ve settled on the Snow level 2 MAF system (#20011). Instead of using manifold boost pressure to trigger injection, this system uses the MAF signal with a variable control unit that can be tuned based off of the more accurate and progressive MAF voltage.
