ATI j-tube w/ surge and Race bypass vavle?
 

When I purchased the j-tube w/ surge recently (haven't received it in the mail yet), I thought it was designed to have the race bypass valve plate welded to it. Now that I looked at it again, it states that it is for use with the Pro-flow bypass valve. Does anyone know if the diameter of the surge pipe on the j-tube is the same or similar to the inside diameter of the race bypass valve plate?

This is the tube I purchased:

This is the bypass valve I have (I didn't get it with the little tube or the vacuum lines):

The J tube is indeed for the Pro-flow valve, ProCharger doesn't offer a tube for the Race Valve for the LS1. Thanks. Bob

Do you know how far off the diamters are if I wanted to weld the plate of the race bypass valve to the port on the j-tube?

I don't recall the size differences, but they are substantial. It woulds be best to do it by removing the tube on the j-tube, and welding the race valve bung in it's place. Bob

Eo you have just the tubes to match the plate of the race bypass valve available seperately? I have the valve and the plate, but not the tube. If so, is there anyway that I can paypal you the money for it and you can add it to my current order if it hasn't shipped out yet?

The race bypass flange expects to be welded to a 2.5" diameter pipe. I would follow Bob's advice, have the small 1.25" piece removed from the J pipe and replace it with a 2.5" piece of pipe.
