not goin' to get in the middle here...but I looked at meth while running with bikecop over a yr ago at US 41 here in IN. I was't sure what effects it would have on the internals so I didn't bite at that time. Hence, watching and learning, trying to get a 'vert to go fast, I just see the meth as a cooling mod although I'm reaching here. If you all do any kind of cooling it helps in all kinds of ways. No leaning out, keeping hp up. I now realize the meth has grt cooling, grt octane improvement as well as other factors. Meth or in the old days, alcohol injection, has been around even before my early '70's racing. I am not going to argue DA having grown up around an airport, where much of our drag racing was done as well. I see the point of the DA discussion if arguing times from a guy in Colorado vs the guy in Louisiana, but now do we argue times with a guy with cooling mods vs a guy without, or a guy with meth vs a guy without....etc...I think we post our times based on our location and what we run...period. This is racing and everyone looks for an edge to go faster...you need just pick a direction and go..racing is racing...just my take on it...not taking sides here
