I had my boss make me a larger puck for my modified exhaust elbow I needed it 1/16 bigger then the 1 3/8 RJC puck. He made it for me out of round stock but its alluminum 1/8" thick, any idea if it will work ok? I dont want it to melt or warp any input would be helpful.
is correct (the numbers vary with the grade of the material) but you only have to reach a temp where the aluminum becomes maliable (easy to bend) and then when the WG closes the puck will deform and may wedge into or stick to the WG hole. Then next time you wack the throttle you have no boost control and you can join the "Head Gasket Club of America"!!!
I would see about at least stainless or the best inconil (sp?) Good luck Jon Hanson
