Bob,
In other words you think the angle should be UP? Your point on the turning of the wheel rotation forces the pinion to re-act in the opposite direction? Exactly! If you dump the clutch so to speak the tires are obviousloy turning in a clockwise rotation, this forces the nose of the pinion to rotate to a "plus setting". This is/was the gratest problems with FFR's a few years ago. Wheel hop was so bad in some of the cars it would knock the dash loose. (I have fixed them.) FFR changed to the new control arms about 5/6 years ago. One FFR with one of the broken loose dash's found his pinion to be over 12 degrees positive with their stock arms.
And a perfectlyt straight line, I am assuming you mean tail shaft,driveshaft and pinion? Or are you just talking about being under power? I would seriously like to see a professional link from any custom car builder to a factory OEM unit that has a "flat non-horizon" set drive line angle?
This old dog is never to old to learn!
My point is, the CR's with a beefed 351-even a 302 under full load, with their or like kind control arms the pinion will go up either adding to a problem with a plus setting or go toward -0-. I.E.; With the Double Venom cobras, Viper V-10 powered and MT Street Slicks, I was lucky enough to have the Honda Engineers (Marysville, Oh.) not only helped check out one of my first DV's, they came to National Trails drag strip in Columbus and not only watched me race they filmed it in slow motion so they could see what all the suspension was doing at launch. From how high the nose lifted to how long it took for it to settle down and how much squat the rear end had.
They did a skid pad test on their track and I will do a little bragging, with their help my DV pulled a plus 1.7 G, almost formula numbers! (Front roll bar disconnested, stock CR's rear sway bar, tubular front suspension with coil-overs, 275lb rear springs also with with
coil overs.
They and "Jegs Coughlin" (JEGS) were at National Trails Drag Strip for the '99 Viper Classics which Chrysler had invited the Double Venom to, to race the Vipers. (Four years and the DV was never beaten-I have the plaques on the wall.....except for the last year.
For three years I beat the same Blue and White Viper. Every year he came with the intention of beating DV. The last race , he (Paul Fischer of Akron) and myself ended up going against each other once again for the Title.
At the last yellow I dumped the clutch hard.... the DV came off the ground and I jumped out in front of Paul by a good car lenght, I slammed second (This car pulled +2.3G's at launch and almost 2 G's going into second. Then it happend, Paul went by me like I was standing still! Well I almost was.....Per the Honda guys, JEGS, and the Chrysler guys that came down to the track and looked at the car all stated my pinion angle must have gone level or even positive as I had actually "Ripped the Ford 9" housing in half! Driveshaft,U-joints,pinion and gears were all fine and actually re-used. The housing itself was litterally ripped in half. You can actuaslly see from the "spli" that the rear end had split from the top down.
I'm serious if you have a link showing a plus pinion angle I would like to see it. Hel, I've eaten Crow before!
Not Enough NEGATIVE/DOWN angle!
