Busa/VW091 Adapter Testing Results
« on: May 21, 2011, 04:50:51 PM »
First REAL testing of the adapter unit mating a busa(limited to 8 PSI boost for now) to a VW 091 tranny in my approx 1800 pound car in dune trim have met my initial hopes fully. Our trip FINALLY to LS got approximately 15 hours of solid thrashing of the unit with constant shifting and hammering through the rpm ranges. Up dunes,down dunes and full throttle ,all gears runs through the whoops many many times. Getting the engine out tomorrow so I can tear down and inspect all of the unit. I'll post pics of the unit and what I find inside.So far,this thing has really panned out.

Maybe I spoke too soon. ;D ;D Pic 1 is of a good spider of the strongest (green 298 lb.ft. nominal/597 max)available polyurethane spider for the curved jaw lovejoy the VW091/busa adapter uses. Pic 2 is of what I used-or whats left of it anyway(red 298 lb.ft. nominal/479 max ) . The normal/maximum temperature for the red is 212F-248F.  The green is slightly higher at 230F-266F. They are both rated for 7100 rpm . The busa at 10,500 rpm has a countershaft speed of6579 rpm so that is well within spec. Anyone think that at the current busa power level of approx 220 HP the green spider can survive? The red one sure as hell didn't!  rofl thumb down thumb down eyes My other option is to make my own spider from some other material. I don't know if this was a capacity or temperature issue. Opinions are solicited!

Not only that but there's no telling how long it ran like that either!

Ya,but defeats the purpose. The spider is there as a shock absorber.

What about delron. I know all of the trophy trucks are going to delron bushings. Not shure of the strength though.

Looking at data sheets now on 4 grades of nylatron. I'm concerned about melting point as I'm concerned temps were a factor in the spider failure as it is and nylatron and the PU spider have similar  service temps. Looking at this stuff pretty strong though.   http://www.cncplastics.com/PDFs/peek/Bearing%20Grade%20PEEK%20Standard.pdf

Nope,enclosed. Thinking of adding windows though. The housing didn't get hot enough that you couldn't put your hand on it for a few seconds. That doesn't really say anything about how hot the spider ran at though.

Unfortunately it has a fairly low melting point also.

not by any means comparing your unit to a sandbullet but they ran a similar connecter but open. don't think there was enough testing done nor do I believe enough of them survived to know for sure but just a thought. I hope you get it figured out cause I would like one for my mc rail if I get mine sold.

It's just an r&D issue. Shouldn't be a problem. I'm going to pretty sure go with the PEEK material. That's not going to fail and will have self lube properties also. It should perform well. Still open to all suggestions though!!!!!!!

Well,crap,it looks to be a biotch to machine though. Have to check into cost to have a specialist do it.
