R034 blower ?bhp?

Post by bmwcapri »

Howdy folks, have had an R034 knocking around the garage for years, the lobes are in quite good nic.

I was going to put it on my Capri. I've set the CR and the injector size to cope with up to 8psi and have been running the engine in n/a since it was rebuilt. Now the time has come to mount a blower i am umming & ahhing about whether to use the old Wade or a more modern Eaton M112 i have.

The flow chart for the R034 shows it pushing a maximum around 480cfm at 5000rpm, which on this engine (bmw m60b30 v8) might equate to 1.5bhp per cfm.

I know the Wade is a bit of an antique, and that the iron/brass timing gears are a weak point - although it might be possible to replace them with new steel gears, & i'd be willing to go to the effort of upgrading it if 300bhp was a realistic target on a modern Efi 4-valver

Can anyone tell me what bhp they have wrung out of an R034 equipped motor?

If you have the Eaton sitting on your shelf why would you want to use the older presumably less efficient Wade?
