The cases has not been proven to cause the problems yet! As proof in two different Dyno's.
Here's an idea, why don't you come to the track & get a clue. Races are not WON on performance only! Reaction times play an important factor & most of my opponents suck. 2nd, it's a different story when you actually have to race with another opponent in the next lane. God many of them start to lose their composure when it gets to the later rounds. 3rd, you can make s shitty run & have how many times to get it right? We make one mistake in under 4 sec. & we are on the trailer going home.
Green, understands what 13lbs. means to us. My Son is 6'3", he would look pretty funny losing 13 lbs. When he's already lean.
Now, you can continue to babble with regurgitated crap. Or you can shut your pie hole & listen to people who actually do this style racing.
I don't know shit about your style racing, but what I've picked up here there. I guess that would make me an expert on it, if I use your rational. Fuck, what have I been thinking! I need to hire you as a Crew Chief for our drag cars.
