just to add a completely unbiassed opinion to this thread, Chip, would it not be a good idea to PM or call Allan to discuss/argue whatever it is you are trying to achieve? Gus has posted to say how chuffed he is with his new engine and you seem to have overtaken his thread talking about some work from 4 years ago or something. I know it is a discussion forum, but no need to mess up the thread with a personal argument? Surely that is what the phone/face to face is for. Just my thoughts. I wouldn't normally post something like this but am ill so time to kill!
