Hey Mr bluerat tell us how you go...Building an L28 and interested in balancer options.

 

Price, where to buy, Part No  etc..

No prob's, SWR's in the front running at the moment although I have to talk to the man at Ross, my Holdensix loving mate tells me theres a SA company that I should follow up and Simon from Powerplay is also on the list..... I know its a long shot but does part number RA2799 ring any bells for pistons, I was told they were RB30, but they have 4 valve flycuts in them. I've checked ACL, Wisco, Arias etc but no match? I will most likley use something else, but its handy to know what was in it?

 

Cheers.

Funny you should mention this, as I've got 3 balancers from 3 seperate L28's and they all are different diameters????? You'd probably gain a killer wasp or two by changing from a large one to a small one. Just tidying up the other day after a few brews and thought I'd had too many but they were all definetly different sizes.

There is a very well balanced BMW one that alot of race L28's use, you need the key re-machined or something to suit.

 

I never found out which BMW it was though!

I got my 8 inch BMW balancer from Len Brennan here in victoria, clears the water pump pulley by 5mm  :o

You'll have to show me next time I see you Gareth, I'd like to see one in the flesh.

How many pulley's can be put on it though? Mine has power steering, so may need one more than you.

It's actually two separate pieces that bolt together so I can't see why a double groove pulley couldn't be used. Try Len Brennan or Robco, you may be special enough to machine up something yourself Simon  :P

Sample required.......  :) The pulley looks datsunish  :-\ and it has a central locating ring/lip/step that is a machined to fit the centre bore of the 8 inch BMW balancer (Like a wheel hub), then theres 10 high tensile (12.9) bolts keeping them together. Sorry if my engineering talky is confusing  ;) It's hard to put it in laymans terms  :P
