Blow-through backfire question.
Turbo Mini Forums

Obviously, with a suck through system, a backfire can be very bad news. Old Shorrock units were fitted with a BOV in the kit.

I wasn't going to bother with one, but having a think, it might be a good idea. I wouldn't have thought the amount of charge was significant, but it might be.

Before I explode something expensive, what are your (relevant) thoughts?

Bugger off, I'm getting there.

If you get into backfires you have screwed up big time somewhere. Using the factory settings when initially starting the engine is a pretty safe starting point.

have someting "disposable" on the engine side of the throttle, or after the charger you dont mind blowing up to save everything else(like a fuze!)

reason i say that is a poerson on another forum i use "tested" his nitrous system by sitting in teh car and jsut opening the throttle and listeni9ng for the solenoids to fire, but naturally this fulled the plenum with a nice explosive mix. closed the throttle and went to start it and bang! could have been bad, but because the plenum had a week spot, a wee cap just blew off the end with no other damamage!

I have had a think and reckon that the amount of pipe after the blower would probably absorb the shock I would get with "that much" fuel, if it spat back. I will go without, I think

I would't I have had mine backfire and I'm glad I that it has a blow off valve.

I run a supercharger and I don't care the TB is on the wrong side.
