Hi Martno1fan (or may I be less formal and call you Mart)
Neat looking engine and looks to fit a treat! How are you cooling it? It looks as though a water jacket might be difficult so I guess you'll be sticking to air cooled. It will give you a good excuse for not slowing down
When I buy racing engines, I am too tight to wear them out just pottering round the club lake so tend to just set them up and stick them back in the car (after answering the obligarory questions from local children - "How fast does it go?" and "How much is it to buy?"
I run most weekends wherever the races are
This year its Torquay, Bristol, Telford, Stevenage, Tamworth - home club, Tredegar (Mid Wales), Burton on Trent, Weymouth, Milton Keynes, Eastbourne, and Lake Windermere.
I don't know anyone who races from Blackpool and "DM" is not a "real" offshore racer, he mainly does World Champs and big internationals
Given the length of pipe you'll need (12 - 15K rpm??), it looks as though you'll end up with a LOT of pipe hanging out the back
Keep up the good work
Danny
