i need to know the inside hole diameter of any keyed serpentine 6 rib pulley. all i have is a cog mini but i need a serpentine. thanks

I think Ive got that pulley, its a 6-rib for my 144 b&m blower, and it has a keyway in it... What exactly are you asking for again? Where do i measure? the keyway SIZE? like how long? how big? its pretty small... Im going to guess a general idea but probably like 3/4" inch long and about 1/4" wide but for SURE i cant tell you right now. what are you asking for again?

Like if you took the pulley off of the blower you could stick your finger in the middle hole. I need the measurement of that hole. See Ive got a fageol supercharger set up for cog but I want to just run it with my stock serpentine set up. If I can find another pulley that fits I'll be so happy. I measured my matching cog and it came out to be like 13/16"

Do you know what I mean , nice car BTW , saw your post.

no the keyway itself was very small, like as long as a long fingernail (unchewed) and wide as a... uh... hmm... maybe like 1/4" inch wide.

So we have Width 1/4" height 1/4" length about 1" inch. sort of like a long rectangle block. i would draw a picture for you but im sure you can figure it out.

I dont need the key measurement , I need the diameter of the hole the round hole that slides over the supercharger snout. Not the pulley , the pulley hole.

does this help at all?

Can you take off the nut/washer and measure like this for me?

SATURN5

I believe hes requesting the inner diameter of the blower shaft hole. Or in otherwords.. whats the diameter of the blower shaft?

614Streets

Say SATURN5 they made keyed m90's , whats your shaft size??
Assuming the keyed Magnuson is the same as the Eaton non keyed unit.

ack. ok. Well I sold the blower so I no longer have a blown thirdgen. sorry. but i will have a nice 671 or a 250 C.i. holley blower. or a multi point fuel injection setup with a vortech V-4 so I can make 1000 horse. or not.
