Yeah I want to know the cylinder to cylinder measurement,as well as the total depth to the cylinder liner.
870cc big bores have been done, I just don't know how to get in touch with the true source Brian Law..I would think that either Brian worked out that 6mm MMC sleeve walls were still thick enough or He replaced them with them with tougher steel sleeves 6mm thick.
What I'm thinking is what if someone was willing to bore the cases for sleeve larger than 88mm in diameter, say 92 mm?
Even if you stay with 7mm walls (the allowed overbore thickness of the mmc liners) your talking about being able to fit 78mm pistons.
That puts you over 917cc's.
That's getting into a very over square engine. In fact it is so far oversquare, that I'm starting to think about the rods and a stroke increase again.
Now with the information about length of the rods, and total length of the cylinders, a stroker kit could be put together with a crank and alternate length rods.
well John your in luck. I know Brian, grew up with his boys. he lives about ten minutes from my house. I also know Bruce Allnut the mechanic that worked with Brian when he had dynamohumm. I've brought up a few of these threads to him in the past, explaining there is still interest in the projects they we were working on. But that whole endeavor ended kind of bad. there seemed to be little interest on his part. But I will give it another shot and see what he says. I'll try and get him to read some of the threads. Who knows I might be able to convince him to join for some Q&A (don't hold your breath) .
