The Place

An also if someone builds one we can weigh them both and see what the result is. But they need to be allowed first lol

Just put the discussion of the bored/stroked Beemers a side for a minute and get back to the "normal" 1000cc BMW engine, BMW introduced the R100 in 1976 so why is it that these engines are used in pre-73 Classic Sidecar Racing...?

I don't think there are any major differences. Its possible that they are just more readily available.

the only major difference between a pre-73 Beemer engine and the R100 engines is 250cc's....!

And there aint no replacement for displacement!

As long as the engine looks the same on the outside which i believe it does,the capacity of those engines is OK as the capacity limit for the period and the CRMC is 1300cc.

Thanks for clearing that up, wasn´t sure what the rules were in that department.
So a 1300cc Irving Vincent engine would be just fine then I think? It looks the same on the outside and pumps out 135 bhp...
Who's taking the cheque book out? Eddy?

Kieran, if I could find a Tin basher capable of building a Tin Bashed Busch I would order one in a heart beat.

I could put you in touch with one !

I reckon Rod is going to be busy.

Going back a bit in this post. My old mans Manx outfit with bolted on Watsonian would not fit in a Thames. The sidecar either went on the roof or was tipped on its side in the said Thames.

If that's is the case then we are back to the hypocrisy of only allowing Honda`s to be 836cc

I think when this rule was made those that made it had memories of them being so incredibly quick that they would runaway with everything,I think the idea was to help to make closer racing and that big capacity engines that were not done in period so obviously should be restricted to the capacity they were raced at within period which I think was larger than 836cc . To make a rule which said that no engine should be no bigger than it was ever raced in period would be difficult to control as there will always be someone who remembers one being built and raced and those who claim to have done it. So i believe that any engine which was around in period should be allowed including Konig as long as there is documentary proof. And although many currently used engines are possibly bigger than used in period they could have been done if anybody had wanted to,so with this in mind I believe the up to 1300 cc rule should remain for all engines.

The Honda is fine at 836cc. They have a habit of blowing oil out and overheating if the capacity goes beyond this. They are competitive with the BMWs and the Imps at this capacity..

I don't know why people moan about classic racing costs when a good F2 is around £30k and same applies to an F1. Also entries for modern racing are also more expensive. All motor racing is expensive so we should count ourselves lucky

Ed, I think it's up to people to find the limitations of their own chosen engine and as you say the Hondas are competitive already but those that use them should have the freedom to go bigger as you and Clint have had with your Imp's.

I would like to discuss with him how he envisions the finished machine and the toil involved in getting it to the same standard as the Busch. R&D by "others," can be a slippery slope so his vision is most important.
