Hey guys, new to this forum and supercharging but not to mustangs or cars.
Anyways, I have installed an m90 in my 89' Mustang and its from a 93 tbird.
Everything seems to be hooked up right but I have a problem with the hose running before mass air flow blowing off ?
I have an aftermarket bypass valve but I am under the impression that it sucks, as it appears to not be functioning. When I am at idle , my vacuum gauge reads 0, so it is obviously getting boost.
I am running a 2 3/4" pulley with a 3 3/4" crank pulley so that should put the blower at approximately 12,000 rpm @ 6,000 engine rpm, well within the m90 limits.
Any ideas besides the bypass valve being crappy for the hose to blow off.
Also, when I didnt have the bypass hooked up, I had a breather in the valve cover fill spout and the fill spout was connected to the throttle body. I assume it was bleeding off there and thats why it didnt pop off. Whenever I would give it throttle you could see the rubber piece connected inbetween the MAF and throttlebody sort of balloon (about 1/4" more than usual).
Some pics are attached of my current setup. In the pics it doesnt show the bypass valve, but it is in place of the middle of the long pipe that runs by the radiator.
Any help would be greatly appreciated.
