ive just installed a antilag system on my saph cosworth but after a about 30 seconds use a couple of times, my new ish tt38 housing has cracked in two places!! and the car was left running after for ages is this common? wheres cheapest place to get a new 63 housing ive been quoted £400 by tt and td... i'm gutted it doesn't appear to be leaking boost yet but it overously can't handle the anti lag heat!! can the housing be repaired?

cheers
