    Intercooler block off question

    Should I put a bead of silicon between blockoff and the block?

    If so what should I use?

    thanks

    Most definitely. I used Permatex "The Right Stuff", and it has worked well with no leaks.

    One of my basic rules is that, if a machine is designed properly, it should require no gasket sealer on assembly. I just received my blockoff yesterday. With a v-band clamp holding it together and an o-ring for sealing, it will require no sealer.

    Mike, take my advice and please seal it with some sealant. We have proved time and time again that even with the O ring seal it can leak. Use sealant and never have to worry about it again.

    I used Permatex Ultra Black silicone. Use a nice heavy bead...

    I used black silicone on mine, use plenty the first time. It is not much fun to do over.

    yeah just finished. That V-clamp did want to play.

    Suddenly it just fell into play and of course the bolt was in the moooooost convenient location.

    Judging by the color of my hands I think I put enough of the right stuff on.

    Bad idea unless you want to run into some of the problems I did this summer. Was running 69mph with a stage 2 and a horrible holeshot (worse than stock). Sealed the blockoff with silicone and instantly gained 4mph and a killer holeshot. Couple other things here and there and now I'm running where a stage 2 should be...75mph.

    if you have your intake exosed ..and rev the engine a little you can see it move around and expand... thus why an o ring just isnt enough
