[VintageLambo] Re: Turbos and Suspensions

Interesting Laust.Two more points re the Supra (in my OT discussion, which is now more OT since you are actually putting twin turbos on your Lambo!) -- the Supra is twin-turbo, using 2 different size turbos.The small one comes on first and creates a nice transition to the big one, thereby making it quite drivable, even with a huge blast "upstairs." However, these HP guys typically take the TT setup off and run a single huge turbo to get the really big numbers. Also, since the motor is designed by Toyota to take these loads, I would think the lower end is beefed up anyway. But your remarks are interesting, they ring a bell -- I"ll try and find the ref. Back to Lambos...There are various "thrust rings" in the rear 400GT suspension designed to center (actually "locate" since you may want the arm offset for alighment purposes) the arm or link on its bushing.They appear to be made out of Delrin.For example: http://www.geocities.com/lamboguy/PC21_RearSusp.html RN-01028 is the "location ring."I"ve made a few of them on my lathe -- based on what was on the car -- and they do not seem to hold up very well. Any ideas for other materials?Keeping in mind that there is a swiveling movement between the arm and frame ears.Delrin is nice since it is a bearing material, but it doesn"t seem to have the strength needed for my car.The result is that I set everything up, drive for a while, check the alignment and find it is off becuase the delrin ring has deformed (somewhat squished) a bit. Long, long story...but that is one of the problems with my rear suspension.I"ve summarized this at: http://www.playerviolin.com/carstuff/RearSuspension/rear_susp.htm Which I need to update.I"ve got the suspension back together now and am trying to dial it in. Anyway, any suggestions are appreciated. Best, Fred
