Alcohol injection complete - awesome awesome awesome

[Jon K]

So today my friend Jay and I worked from about 930 - 5 and got a TON of **** done. I did a lot of powder coating for **** other than the car (amplifer for the car, desktop PC tower case for the house), powdercoated the charge pipes wrinkle black and plumbed and wired the methanol injection and its now complete.

I got on the highway going home from Jays (about 1hr or about) and started logged. Car felt notably stronger which was a good kick in the pants. If you want to know my opinion.... this **** is freaking ridiculous!

My intake temps go like 8 degrees under ambient and then climb only to... 90 - 92 max! Not that my IATs were very high to begin with, but I the datalog I have here is about 35 minutes into driving, having hit traffic on PA turn pike, getting back up to speed and then ripping on it.



Few things to note - the AFR are definitely rich. I am running about 60% methanol. I went from being about 11.5 - 11.6:1 AFR on 93 octane fuel. Now when I go wide open over 5 psi I am about 10.2 - 10.5:1 AFR. That confirms my ~60% methanol estimation because 50% methanol yields a 0.5:1 AFR change. I am running the 475 rwhp jet and have the 600 rwhp jet on hand. Once I add the nitrous, I may swap in a 250 rwhp jet for water and keep the 475 rwhp jet, as this will make for nice atomization of the alcohol/water in the cooler pipe as well as add enough fuel/water/alcohol to handle everything.

Now the cool(er) part!



I tried out antilag in boredom to see what the methanol kit would do as boost built in neutral. Here you see antilag from about 4100 RPM. What you see is a SUDDEN metering of 198 kpa (14.2 psi) in NEUTRAL. Just like if I had sitting at a light, rev'd up to 4100 and pressed antilag. This is freaking amazing - I previously could only make about 6 - 8 psi with antilag on this large turbo. You can see in the datalog that I dumped the clutch and went with it in 4th gear - it was a nice rush.

I really recommend this **** to everyone boosting their car. If you are on a chip tune, that sort of sucks because you will NEED to pull fuel or you'll be rich. Everyone else, this stuff is CHEAP, fun, and damned effective!
