thanks tony, good luck with the test. be interested to see where the AF needs to be to make best power.
LPE "leaned out" my engine as much as 13-1 trying to get just a bit more power with alchy you might be able to run that lean or even a tad bit leaner and make better power. lean is mean but not very "safe" I'd love to tune an LT5 on e85 and see what it could do. would be a fun experiment. I'm trying to sell my turbo buick to keep my other hot rod projects going. but after driving it the last few days in the cool air it makes me want to slap an alcy kit on it and just crank up the boost! that old buford is every bit as fast as the LSV and puts as much to the ground with only 6 cyl on low boost. at 24 PSI, foggedabout it, it's up over 600 at the tire on race gas. keep us posted.

The alchy didn't make much if any difference to my A/F ratio during the runs. Perhaps because the amount of alchy needed to equal the power of gasoline are not equal. You need a lot more alchy sprayed into the motor to equal the power of gasoline therefore that may be the reason for no change. Just my guess. ![]()

Update: After a careful review of my two dyno runs I discovered that I gained 10 hp and 10 lbs of TRQ from 2500-5500 RPM with a peak of 2hp and 3lbs TRQ. It isn't a whole bunch but my intention was to prevent detonation and use the cooling affect of the water/meth. The car does feel better when running WOT with it on.

The LT-5 isn't a motor prone to detonation, certainly not at the top end. I've had mine on the dyno cranked to 35d and all it does is lose power. Torque peak is where you need to be less aggressive w timing to avoid detonation. So 4500-5500rpm. Having said that, you run through that rpm range PDQ and don't really re-visit that area at WOT even when shifting.
As for AFR, I find my motor makes best power at an indicated 13:1. I'm going to re-test that given that we use e10 here and calibrate based on Lambda rather than AFR.

Thanks for updating this Tony. My engine is getting the water/meth treatment not so much for the power. As helping reduce carbon buildup on the valves etc. I believe that big cam reversion makes the carbon build-up more of a problem.

Methanol is a chemical intercooler that on n.a. engines does its job in the combustion chamber and acting as an octane booster.
I do not think it will add more power in the warmer weather. I would add timing and see what happens. Check this video out. http://www.powerblocktv.com/episodes...al-intercooler

Yes I agree, not add more power......... but recover some power in hot weather.
