Paul, I'm going to try to get it on a truck scale this weekend. We never did weigh and add as we built, but we're conservatively estimating 1,500 lbs. based on a pretty educated guess. I appreciate the comment about 'well engineered,' too. A whole lot of math has gone into getting this right, and it's designed to look deceptively simple. It means a whole lot coming from you and the other folks here who have so much more experience at this stuff.
And credit where it's due, Jimmy The Wrench is a damned genius. None of the Hoopty's modifications would have been possible without that guy's 20+ years' experience with drag cars.
I may do the roll-bar padding in the spring, but I want to get used to the limited field of view I have first. I can't see out my rear-view unless you count the top of the car directly behind me -- but I'll be making a new, taller, mirror stem out of a ball bearing and a pushrod.
If I look over my left shoulder, I can see from about the eight o'clock position back to the four o'clock as I pan my head to the right. Padding the hoops would limit that to being almost a straight right-hand three o'clock view because of the narrow slice of tubing that I CAN see through as I look back and right. That slice would be blocked by the addition of another inch or so outside tubing diameter.
I did read the piece on the PCA site (talking about SCCA roll bar padding advice, merits and demerits of roll equipment in street cars and the driver-safety commentaries) as we were designing the hoops and placing them, so they're far enough back that I can't possibly hit my head on them when I have my five-pointers on.
Where does your mellon sit in relation to the tubing on Butch? -- I know you didn't just do that roll bar for looks, so I'm assuming the padding's there because of the same concerns?
The photos:
The first one has the marker lights on it and the fogs adjusted for height and angle -- owed those to Todd Sharp and TC.
Second, you're able to see the frame is only left-right horizontal under the seats. If you look at the tranny bracket, you'll see it's at exactly the opposite angle as the roll tubing under the very nose of the car. I don't know if that's a combination of CMC's efforts at adding the two-inch box around the old pan seams, or if it sat unevenly on jackstands while we welded it up last winter. I only just noticed that, and there's a distinct possibility it's a combination of both.
Everything looked plumb when we were welding, but now the body's got minor alignment issues where the Dzus fasteners meet their sockets, and I think I can see why -- although it runs a good, straight acceleration line. I've still got to tweek the toe, camber and castor, but for something that just got back on the streets ... I'm not even going to worry about it unless it becomes pronounced over time. It works, but that bend is really very obvious in this picture, so I thought I'd include it here.
The third shot is the genius. Note the SEG?
