i am putting my vlt on gas reasearch and just want to know if i can run a blow off valve, cause my only concern is that if i run a atmospheric bov that when throttle is realesed, the gas might build up in the x-over pipe and get released in into the engine bay via the bov and of course that would mean (booooooooom) which i don't want has any one run a atmos bov on a gas set up, using a x-over pipe or a bov that is close to the tb, or do i need to get a plumb back

should be fine dude the gas research throttle body is between the plenum and the turbo obviously - not before, making it a blow through setup, not draw through, so the gas wont build up that way, and the GRA throttle body uses a metering rod to determine the amount of gas let thru, but when the throttle is closed it bypasses the butterfly anyway so the gas at idle or closed throttle is added after the butterfly. u may still get a slight smell of gas in the bay, but maybe more so than normal an impco setup might have the issue ur talking about above because it has no metering system, but not the GRA stuff. hope this helps

cheers mate just wanted to make sure i was not going to hear any explosion noises under the bonnet

depends of where the mixer is placed like misk said you could run one but it would be best to have to be a plump back one, but it may stuff the a/f mixtures best off talking to a gas place and leting them know what you plan to do i had a mate that had one on a falcon turbo and it stuck of gas every time the valve opened which is not good
