Modifying the Beams 3S

[Billzilla]

It would be interesting to see what the specs of Bate's RS200 that he used in targa a few years ago, as that sounded bloody fantastic.

Anyone know ?

Yes, I do ...

I know they got in excess of 270hp from it, and very reliably.

Anybody know about the rods in the BEAMS engine? I note that the engine shown uses the original rods.. And at 8800 rpm, mean piston velocity is 4966ft/min. Ouch.

I've seen an original BEAMS rod and they are a very small item. Not a real surprise that they replace as they are about half the size of an ST205 rod.

This one was very interesting as it was put into a "development" motor by a certain well funded race team and run with 28psi of boost. The one I saw had 2 bends, one at the top and one in the opposite direction at the bottom, so it effectively shortened the rod by about half an inch. I was very impressed with the choice of alloy they have used, it didn't break and they only noticed because it was making a tapping sound as the piston skirt hit the oil squirter!

Cheers,
