Hey guys,
So, finally signed up for my first big track DE with the PCA out at Texas World Speedway this weekend - anyone from here going to be there? Finally got my car corner balanced after getting all of the rubber out of the suspension (elephant poly bronze up front, mueller bearings in the rear, koni sports all around, 21mm welt up front, five lug conversion with M calipers, and re-drilled hubs in the rear, running 15x6 cookies and falken azenis) The car came out at 2154 lbs with a little over a half tank of gas and a 170lb driver. Not bad for an all steel '74 body that still has the crash bars in the doors. And we got her to balance at 50.2% - Thought you guys would be interested in those numbers. I am pretty excited about this event, and curious to see how I match up with these newer porsches. I think my car is a good 10 yrs older than the oldest car out there, but I do have some Mr. Raby magic to help level the field (IMG:style_emoticons/default/biggrin.gif) Anyway, I will post the results after I get back...and any comments, suggestions are welcome.

Bill - The oil temps got hot ... after about half way through the sessions I was hovering around 230-240 ... and a couple of times I spiked it at 260 right near the end. Then I figured out I could drop the oil about 10+ degrees by going into 5th on the back straight and not pushing too hard, that helped alot. But I expected I might need a bigger cooler, and the lines are already there, so it won't be a big issue, this setup has lasted me 3+ yrs and many autox's, just not good enough for the track.
Chris - I highly recommend going to the elephant bushings and koni's - the car actually rides ALOT smoother than it did with either stock rubber and tons better than the weltmeister poly bushings that I had in there before. I can go over bumps now and it doesn't upset the chassis at all, in fact on turn 12 at TWS I was consistently clipping the edge of the curb at 70+ mph and it didn't phase the car at all, you will really like the setup. How do you plan to get 200-300lbs less? Going with all fiberglass panels? Tony |
