Re: I'm so relieved.
You might need to explain exactly your "rotation"! If you only changed the relationship of the rear joint to the pinion flange you changed "nothing" in relation to the drive-shaft and that seems to be what you imply here.
The only explanation in this case would be that the balance of the pinion flange isn't correct. If your pinion flange is an original it would have a sheetmetal deflector that would have a weight on it. I've heard of the pinion flange being balanced with a drive-shaft assembly but I've never done it or actually seen it done. NOW if you removed the slip-yoke from the drive-shaft and rotated it 180* you certainly would have effected balance. It would seem to me that there was more likely an install error the previous install or maybe one of the tangs on the pinion flange has been compromised and allowed the u-joint to be secured off center! There's one simple remaining fact though, if you "saw what you explain here" the drive-shaft needs to be removed one more time and checked for balance and the run-out you explained. It certainly shouldn't see "speed" until it's verified! |

Re: I'm so relieved.
I don't want to over anylize it because it makes perfect sense to me. Its pretty simple. It works one way and not the other. When I ran top speeds in it, it was aligned just like I have it now. As far as ZR-1 not going past 166mph I have to laugh because even the data on this site shows them going between 175 to near 180 factory. My car dyneod at 342rwhp@336ft lbs tq at Coreys. Nothing special and I hit 179mph pretty easily. I have the video to prove it. I posted the video on here a couple of years ago. I thought everbody had seen it but I guess not. My car is no where near a 415. I guess not many guys on this site have tried it.

So, my friend...I think we're in "violent agreement". Come shoot some competition rifle matches w/ me and we can talk about concentricity, runout, and match case preparation. Dayam! Is it spring yet?? P.

At the Nellis mile shootout, I went to, most 350 ci ZR1/s ran around 155/160 mph top speed, Demps yellow car, modded exactly like mine at the time, ran 166, ergo the number, my car was modded by m. Haibeck, it dyno'd 424 rwhp. (I have the dyno sheet to prove it).lol.. I have had "Oprah" to 162 mph, Ted Feder's lightly modded car ran 162, all i'm saying is you must of had plenty of room, to get you're car to 179.... in my neck of the woods we don't have the place, to allow us to stretch her legs so to speak. The Morrison world record run, also ran In Texas, was on a test track in Stockton, under controlled environment, with plenty of road to get up to speed. I know that anyone that has a video of themselves running that fast would cherish it forever, I would, so please re-post it, I would really appreciate it.

Re: I'm so relieved.
It does take more than a mile to get to 180!
