1 - use anti lag for fun and in anger at TOTB
2 - weld breaks loose on headers:

3 - headers expand with glowing white hot from anti lag... :

4 - fan unit catches fire and fire goes out on the cool down from the last corner to the paddock and is just smoking when I come in.


5 - cut off offending portion and patch up wiring and replace fuse ....
but the rad at the corner by the headers was also damaged and has now started leaking grrr
