Thread: 460 EFI Air Pump

Tweet

Okay so i want to take my air pump off my 89 F-250 does anyone know what size belt im going to need for everything to be nice and snug only reason why i want it off is because i took my stock exhaust off and put on headman headers, jegs X-pipe with dual flowmaster 40's and it sound nice. So with no huge A$$ conv. i dont need the air pump anymore.

No idea on the belt ,....but I have a 89 ....did the headers fit well and make a bunch of difference ?

is that V belt? if so just follow this formula to get a Gates belt of the right size

67=3/8" Width

68=1/2" Width

69=5/8" Width

just measure what you will need with a string to get it's length

then take your belt width, it's probably 5/8" so 69, that's the first part of the part number, then take your length and add it to that number, so if you need 50" just order a 6950 belt, pretty simple.

Yea the headers fit good i got them from summit they were $222 make sure you get the egr ones enless your taking that stuff off and there is a big differnce with the setup i have on the truck now its mean sounding and it runs alot smoother next is a cam.


thanks for the help guys i'll prolly be doing this in the next
