I simply said, I never will tell one of my customers to switch because he will go FASTER.. You don't switch to methanol because you are wanting to go faster..

On a boosted application, different story...
He was not on a boosted application, and his results are not isolated. many people switch to methanol (correctly) and pick up a bunch

again, look at the stoich of methanol against its BTU energy and compare to gas

i understand where your comn from back in the mid 90s i built an old school destroked 400 to a 377 had it in a very light car on 150 shot it went 5.55 and i upped it to 250 shot and only dropped to 5.44. the tenths get harder and harder the faster you go.and then again i may have been doing something wrong there too?

I've never done it with an LS engine..
However, I have tuned cars 1.8 seconds quicker than that to the 1/8th...

Shouldn't need the extra system to go that fast. People have gone 5.0's on just a plate and the old M/T. 4.90's come January...

How much did you mill the l92s with the wiseco +12 piston?

I have the same piston and head combo but was curious how much I could mill later on if I wanted to... I'm right at 11.9:1 right now. Not sure if I really want more though.
