Hi
My sons R31 drift car recenlty had a silicone boost/ vacuum hose fail on his wastegate killing a motor, I suspect that its broken piston ring lands but we havent pulled it down yet.
He's using a modified stock ECU with no boost input so we were unable have overboost protection via the ECU.
He was running a eboost street which has overboost but has no affect when when it cant send a signal to the wastegate.
So I came up with the idea of using something like pressue switch to cut ignition power if overboosting occurs.
I just ordered one of these units http://www.ebay.com.au/itm/220962063461?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 which I will hock up via relay.
I thought this maybe useful to some VW drivers who are using blow through setups with carbs.
