Automotive How long until vacuum (Hg/In) drops off? (turbocharger)
Just wanted to say i put a shop vac in the end of the 12ft pipe.. (also tested the shop vac and it showed about 10HG/In) the result: the lag is virtually non existent! It even spools the turbo! Amazing to me. I may be one of the very few who can actually prove rear-mount turbo lag is a MYTH...- Forcibly-Induced_232

I missed your post, sorry about the delayed response. Your assumption is correct, the vacuum is being measured at the engine at idle and i was trying to measure from the turbo at the end of the 12ftx2" pipe(it has a port for the gauge hose). I may either have air leaks at the couplers(where the...- Forcibly-Induced_232

I'm not always great with words and i don't think we are on the same wave lengths here. Obviously drinking from a straw requires vacuum and a 6 inch straw doesn't lose any with such a narrow diameter and short length. If one was to suck or blow on a 2" inner diameter straw that is 12foot long...- Forcibly-Induced_232

Powered by exhaust gases. Used to create positive pressure. I just need an idea of how far a vacuum pressure can travel. It will give me a general idea of how far positive pressure can go and how long. I'll just get a vacuum and attach some pipe to it. Wont be as strong a vacuum as an engine...- Forcibly-Induced_232

I may just have an air leak as i have not yet clamped(sealed) the silicone couplers down yet. A boost/vacuum gauge connected to the turbocharger only showed .5 hg in . I will find out soon if a leak is the culprit but at the same time i am wondering how far a negative pressure can travel before...- Forcibly-Induced_232

I've been searching but i can not find the answer. This is for my turbocharged car. I just fabricated a rear turbocharger at the back. Really not sure how to word this,sorry. Question 1: So my car produces 26Hg/in vacuum at the engine. About how much pressure drop per foot is expected? The...- Forcibly-Induced_232
