901 power limitations Options

[-JR-]

I've been planning components for a 3.2 914-6 car. I had been planning on using a G50 transmission but now from a reliable Porsche enthusiast, who also races in SCCA, that a 901 would be a better route. Primarilly that it "should" take the power and it's a significant weight saving over the G50.

I want to run a stock 3.2-6 which I believe turns out around 220HP and about the same for torque.

I've seen offical Porsche litterature which stated that a 901 transmission is good for up to 148FT/P of torque but they have been used up to 235 in race applications with dimished life spans.


This car is being built primarilly to be an auto-X machine, but it will also be used for PCA touring events. So I need a trans that can take heavy punishment over short auto-X stints.

Has anyone on the list had experience with this?

Thanks!

G50, I've read several times how they stick out the rear, is that because the bell housing is longer than the 915 and 930? And that is due, from what I understand, is some type of vibration damping rubber hub.

To, cut this short, I read an article where this guy wanted to use the G50, for the gear ratios, and he didn't want to use the G50 clutch, plate, and hub, he went with the, I believe 930 clutch package, and machined down the bell housing to the 930 & 915 length. And didn't notice any additional vibration with the hub removed . With the bell housing now machined, wouldn't a G50 now sit in the same location as a 930 or 915? Anyone aware of this prcedure? Or this article I'am talking about?
