850 Is So Much Fun

Surprised by how it revved to 40mph in 2nd, 60 in 3rd, never had such fun in such a low powered car!
I'm aware of the inherent crank weakness at too high sustained revs so I won't be abusing the motor on a regular basis.
If you haven't driven the route mentioned I'd highly recommend it, just be wary of numerous sheep going over the high ground. I'm lucky to have these roads on my doorstep

It's the Muntjac deer you have to watch round these parts, and the mamils.

First things first ! improve the brakes and suspension.
The crank isn't as weak as has been inferred in some of those earlier posts, but when you have the cash and strip the engine, having things lightened and balanced, helps a lot.
Meanwhile, you can get away without line boring the block if you don't use double springs, just stiffer single springs, which takes valve bounce well over to 6,000 RPM, and a 997 cooper cam won't add much stress.
If you go to something hotter like an "Evo 001" cam, go for double springs and cam bearings.
It would then be worth polishing up the ports and chambers, and any time that you get the opportunity, improve the exhaust and carb.
850 driving can be fun, because a lot of the time, you don't have to lift off for corners. If you get too much power you have to start lifting off on bends !
