Pretty amazing when you think about it. Are there any "systems" in Britain's car that haven't been altered, rebuilt or eliminated during the engine transplant? Maybe brakes, but I guess he's even having some issues there.
Actually the complex modifications to his engine, and wring to support the engine, would be enough to floor most of us.
My experience is that with each system that gets changed or altered there will be issues that come up early and some later. As the car gets faster and faster each system get tested against the others at a higher level and issues pop up.
I honestly thought my car would be totally sorted after a few events, but that didn't happen - not even close, in fact I don't have a clue what the car is going to be like when back racing again.
IHMO if Britain gets his car working by this summer he should be nominate for an award. Not only because he personally did 95% of a very complicated install, but because he's smart enough to get all the systems working together in an extremely short period of time.
Keep pounding away Britain. We are all very impressed with your efforts.
