[QUOTE="dirtyo2000, post: 12107422, member: 106904"] My last post on this topic (rant called by some) . First and foremost I have no dog in this fight. I'm not a supplier or either blower. I don't care which one anyone buys because I don't get a penny of it. I don't make my living pushing blower X so I'm neutral. A car running 10.30 s is not enough but we can set something up and I will put daylight between us in the 1/4 and park greyhound buses between us if we stay in it. No I don't claim to be the best driver but I'm confident in my abilities and back down from noone. There is always someone faster and quicker. All I have is 26 yrs of banging gears and about 17 years of that really racing. I have went faster in other people's cars then they have. Had 2 take my car faster then I have (still sick about that one) . I look at things from a mechanical point of view and do research on my own. My experience comes from 27 years of building, modifying, experimenting, and blowing stuff up. I like to make sense out of things and understand what is going on. Some people do not have the patience to read and understand. That is why you have this thread and so many repeats of oil, tires, spark plugs, HE, oil seperators and so on.

I race, motorcycles, cars, trucks, and at one time was playing around with boats and sea doos. Nothing like 60 foot on the water from a dead. On the quest to go faster and spending money you meet a lot of people. Over my short time span here on earth I have categorized salesmen into three types. Type 1- my part is the best.
