914World.com _ 914World Garage _ Lightweight Engine Crossbar

Posted by: porschenut Jun 9 2005, 07:07 PM

I keep staring at my extra crossbar, and then the drill press. Has anyone tortured one of these to see how much metal can be removed and still hold the engine up?
Looking at the lite -6 mounting systems it seems to be a natural way to drop a few #'s.

been done a few times...hopefully Paul will see this and post picutures of his new tube frame mount....

the earlier bars weigh a lot less than the later sideshifter bars which are made from cast steel

Did someone say "lightweight"?

Here is mine. There is weight to be saved but being that the weight is at the lowest part of the car. Replacing it with something lighter will actually raise the center of gravity.

If I was doing a street track car I would drill some holes in the stock bar and leave it at that. I think I saw one like this at RacerChris' shop.

Yes you did.
I don't have a good picture of it or I would post one. It came to me on an engine I bought. A waste of time in my opinion. The weight is exactly where you would want it - directly below the center of gravity. Besides, you can't take off enough weight to save a meaningful amount just by drilling holes in the stock engine bar.

OK I take the above statement back.

I went for the blink factor with mine

For the amount of time invested your bar makes a lot more sense to me Paul, especially considering your purpose-built lightweight car.

Thanks, Chris. I feel better now.
