Has anyone used this valve. I am looking for a By-pass valve that uses inlet and outlet connections for an inner hose diameter of about 1-1/4", because that is what size nipple i have on my intake pipe and my boosted pipe. Do I have any other options? I really would not like to have to weld a flange onto my boosted pipe if i don't have to.

I havn't used this valve, BUT it is supposed to directly replace the bosch. and the o.d on the bosch fittings are 1". So it should work fine.

Forge are 1'' in and out. It a direct remplacement for the bosch...but they are not in plastic.

damn...i don't think this will work for me. I need 1-1/4" in and out, my hose won't seal on the 1" valves.

Could I just get the greddy type-s and use some adpaters to get it to work with my hoses? Does greddy have inlet and outlet adpters to use with my 1.25" I.D. hose setup.

hoses are cheap, buy the valve you want...then go buy the hoses you need.

If you do want the type S, get the correct flange and have it welded to you piping.

The hoses attach to bungs on my intake pipe and the boosted pipe to the throttle body. I have to keep the same I.D. or i have to weld new bungs to the pipes, which is what i don't want to do. However I don't think i have a choice because i can't find anything to use with the 1.25" inner diameter hose.
