flusted 0 Posted July 28, 2006 I have the boost return deleted on my g60. Was wondering,could i fit a dumpvalve on the bottom of throttlebody boost return? Reason i ask,is i think i may be leaking boost out the butterfly. Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted July 28, 2006 No,as it needs to be vented unless on full throttle,you could fit a recirculation valve? it would have to be at least two to match the port size of the boost return. How do you know your leaking? Quote Share this post Link to post Share on other sites
flusted 0 Posted July 28, 2006 I dont,but i ported my tb and took a bit of metal off around the seat of the butterfly by accident. il abandon that idea then Quote Share this post Link to post Share on other sites
