Alrighty. So last winter I made the move to WMI. Where I live we don’t get e85, and all the gas stations only sell 91, except for chevron which some sell 94. As per stratified who’s local to me, our 94 is like American 91 at best. I was getting a lot of ‘bad tanks’ of fuel being tuned on 94 and far too often I was having to swap down to the 91 tune I also had for safety.
mods: intake/filter, FMIC/piping, catless DP, exhaust, plugs/coils, BOV etc.
I went with the AEM v3 kit and a boomba throttle body spacer, and I also added the aem solenoid to control the spray.
i have yet to have it on the dyno. Even if I didn’t gain any power from it, the datalogs with wmi are extremely consistent regardless of the base fuel. I usually do either 50:50 or something 40:60 water methanol.
you can spend your money on boost juice but that’s expensive af. You can get 3.78L of winter washer fluid (if You get the -35°c version it’s usually 60:40 water methanol) but the dyes and soaps can clog the nozzles filter. The real tip is to go to your local hardware store in the paint section and buy methyl hydrate, which is 99% pure methanol. Mix at home with water and you have cheap clean reliable mixtures without paying the premium for ‘boost juice’.
last summer I had back to back track days during the crazy “heat dome”. Both days were 42°c ambient air temps, tarmac was 60°c so track temps were very hot. The coolant and oil temps never went past half on the gauges. Charge air temps were slightly above ambient. I never got any warnings at all, and the car was being pushed to the limit.
You can see the ignition correction low is -.79, but +4.00 which is great. Doesn’t show here but by redline absolute timing is about +15°. You’ll see the high charge air temp is just from sitting in the pit lane, but check out the 55°c and that’s at maxing out the stock turbo.
only issue for track days is the 1 gallon tank is not big enough. I got my warning light for low fluid about 15 minutes in to each 20 minute session, that’s with the 500cc nozzle. I think I need to raise the threshold of when it was spraying so the mid-boost part throttle, I don’t need it really whereas heavy load WOT iswhere it really helps.
do it. Do it.
