Most of what you hear about how evil nitro is comes from people who either never used it, or didn't bother to do their homework.
Forget about using nitro in any sort of gasoline application. The two fuels are not compatible. Low percentages in an alcohol combination (up to 10 to 15% or so) will give you a little cack, a bunch of good smell and just enough seat of the pants to know something good is in the mix.
Once you venture into the 20% range, you've got to look at getting fat on the jets and tuning can be a little tricky. The zone between 30 and 70 percent is a hard one to get on top of. Motor is not sure whether it's a fat alky burner of a lean fueler. It's gonna be lazy or angry.
Climb the hump to the 80 percent zone, and then you've got the real thing...and if you ever decide to go that far, PM me and I'll hook you up good.
