I plan to do the SDCE tensioner over the winter if the funds are looking good. Jody what size is that pulley you guys used for 14 psi on Don's 406??

I remember it being a 3.85", but not positive.

Haha you and Jody both like that idea huh. I like it too but I just love the looks of it sticking thru the grille and it continues to match the color/finish of the engine compartment. Very industrial. Don't wanna hide it just yet!

If it shows 14 psi there then the issue is the intercooler or you've got a big boost leak between the intercooler and engine. If it shows the same boost before and after then you've got belt slip issues, which are fairly common with the stock ATI tensioner (though Don never had a single problem with his, which is why we left it alone). SD Performance Concepts makes a much better tensioner for that , it's a direct replacement and I and many others run it instead of the stock ATI one.

That's right I remember you said that now. I will see if these guys can do that tmrw night at the dyno Jody. I have read about the SDPC stuff and it is spendy but looks to be the top shelf ticket for this problem. We'll see if I have belt slippage I guess.

I thought the 2 pulleys we had are 4.25" and 3.75" but maybe it is 3.85"

Cool thanks Jody. I hope I won't need it but I know where to go if I do!
