VP Racing Fuels Speed Sauce Plus Injection Fluid, 1 Gallon, Pack of 4

This stuff makes good power and at 80% ethanol content really helps with additional octane needs. I'm using it in a modern turbo vehicle that came with only DI so no port injection (Acura RDX, same powertrain as an 18-22 Accord 2.0T) as a means to move beyond the stock fuel systems capacity. The benefit is immediately felt and seen as the post turbo intake (IAT2) temps drop when the system engages and at times even to sub ambient. Making over 30psi on an MHI stage 2 turbo with 0 knock. Ordered 12 gallons to get started and will keep this in stock moving forward!

I have a 2019 WRX with FBO minus headers. Im tuned for this along with E50 FF. My tuner even said this stuff works better than Methanol. We tried both and he advised me to stick with this stuff rather than the methanol.

Been using this product for about a year. Never used water meth so I can't compare. All I can say is that at 22psi on 93 I made 363whp and with speed sauce plus I made 385whp and that's just turning it on. No tune. I'm currently sitting at 26psi making 440whp with speed sauce plus.Now, the one thing a don't see making sense is the price hike. Buying direct from VP looks to be the better option or going 50/50 water meth.

This item works as described and isn’t as corrosive as utilizing methanol in injection kits.

50% Ethanol 50% Distilled water fine spray injection system was used in WWII in B-17 4 engine Bombers in England daytime Bombing Missions.To gain altitude above German fighters' top altitude, mechanics needed more HP, boosted turbos to 30 lbs, that caused detonation & piston destruction. One mechanic designed & built this fine spray Alcohol/Water injection system into intake manifold to cool cylinder pre charge air intake with the steam created by manifold heat. using this system B-17 cud use 30lbs Boost without detonation by creating steam absorbing heat to produce enough HP to fly above German fighters. mixture tested 50 50 found by techs to be best after trying hundreds of mixtures. Too much ethanol lowered cooling steam production.You're not trying to up octane rating, Ur steam cooling hot intake boosted air charge to use higher boost rates and increased timing as far as 35 degrees BTDC. Nothing absorbs heat like steam. In my case intake air charge Supercharged to 10lbs and 35 Degrees BTDC gives 45 more HP on Dyno, using Sunoco 93, no detonation. Do not run without full tank of mixture and absolutely sure system is operational, i have light on dash wen pump starts at 2500 RPM, that's control box adjustable as is amount of injected mixture and use different size fine spray injectors. Injector size i run is 2 #5 Snow Injectors with control box turned full pump pressure at 2500 with no bog down from too much mixture. At Track I only have 5 gals of Sunoco 93 and add 2 gallons of Racing fuel in the event system crashes at worse time destroying my engine cus of 35 degrees BTDC and 10lbs of Boost.
