Fascinating (not A7) engine build film. - jansens - 17-01-2019 This is not Austin 7 related at all, it's a 11000(!) HP supercharged top fuel dragster engine rebuild but it is interesting to see how, even with something as exotic as this, engine building is quite similar no matter what it is. But there are some fascinating details in this film such as them using the erosion of the spark plug electrodes as a measure of how good the combustion is in each cylinder. Or how they use different thickness copper head gaskets to tune the compression ratio before making a run.   Simon
