blow off valve on a M90

[cook]

On supercharged applications do you need a waste gate or blowoff valve on a S/C setup? this will be for a 5 spd 2.5L

No, the SC has a built in relief or bypass valve.

This one doesnt its not a MP90 which is newer and has one built in this blowers off of a 89 t-bird. I'm guessing that you could do the same thing as a turbo and mount a blowoff valve on the exiting pipe to the intercooler?

That would work yeah, if there isn't a relief valve built into it.

^^^Yep.
