Thanx guys. 1st off I will have only 3'' of ground clearance under the lowest section of the tank (the 4' long by 32" barrel shaped extension.) Considering 2 1/2" of suspension travel ( 1"+ up 1"+ down) This is my rough in layout for now. As for the bullet, AA/F Blown Alcohol, already got it. Now for final gear ratio, Mark at Pro Gear says, and I tend to agree (thou my knowledge of all this is purely conjecture and Zero experience) with all things considered and factored in togeather, considering engine horse power and RPM shift point, transmission gearing and overdrive ratio, then factor in ring and pinion ratio seems like the tall dia. drive wheel comes in pretty comfortable at 30". Now, after driving a 800 H.P. blown 440 Challenger in the streets for 15 years and a good bit of drag racing and being a chassis and rear end fabricator, it's easy to see why I chose to complete the entire chassis and shell on my tanker and leave the rest of this till last. Sure I can run a lower height front tire, just place the axle lower. But what about a 'cower catcher' type front spoiler scrapping the ground and shooting as much air as possible out to the sides, But aren't drop tanks designed to 'Fly' better because of equal pressure on all sides? Also, after considering axle location and tire height, what would be a good rake on a 24' tank with a 13' 6'' axle to axle length? I was thinking of 2'', this is in conjunction with front and rear down thruster wings. I will post picks when I get the hang of this photobucket program that Slim was good enough to send me. It's a real sweet tank. be worth lookin at. Oh. got my smoked canopies today from Todd's Canopies. Great guy, Great price, great quality. and ZERO visual distortion! Keep the info comin guys, I really appreciate it.
