I forwarded Dave D's NO2 info to my pal Freddie Klies, Eastern Cycle
Performance, builder of my #343 2 stroke engine and he reminisced a bit in
agreement. here's his response...................Bob, no no2,Wanner

This is exactly the same theory I used when running my Pro Mod bike. I always
thought I had the fastest Pro Mod out there off nitrous. But that was like
bringing a knife to a gun fight. Fact is for a while my bike would have
qualified for many of the events without nitrous because basically I had a
decent Pro Stock engine that I sprayed with nitrous oxide. The leaders in the
Pro Mod class were building basic large displacement generic engines with
lets say 200 - 225 HP and bottle feeding in 150 to 175 HP! The resultant
"carnage" every round from doing that was wayyyy too much work that I cared
not to do between rounds so I took a 265 HP engine and sprayed in 75 HP.
Those guys were literally going across the finish line and if you were on the
return road, you could honestly see a mist of N20 spewing out from the engine
from wherever it could come from...base gaskets, cylinder head gaskets. Good
thing too because the capability of this happening acted kind of like a
"safety release valve" of sorts. The engine would have grenaded and blown up
if this didn't happen.The possibility of hot chunks of what used to be your
piston, connecting rod or cylinder head casting coming out of your pipe EVERY
SINGLE TIME YOU CROSSED THE FINISH LINE was not my idea of how to have fun
racing. But ya know what?...they won and I didn't. I ran impressively albeit
with some level of dignity, but they just pummeled their way to the finish
line with the "sledgehammer theory of aerodynamics" (you punch giant holes in
the air with horsepower) and absolutely no regard for anything even close to
trying to keep the same engine in the bike for 2 rounds of competition! At
the time, the front runners of the class were running 6.90's to high 7.0's
and I was running 7. teens, 20's and 30's and I had the same engine in my
bike for 2 seasons with nothing other than normal routine maintenance. They
were sweating in between rounds changing engines and I was in the motorhome
"eating sangwidges." Of course, those willing to put that effort forth made
the final when I went out either first or second round. Wish you were there
Bob!
