I have removed my Radix on my truck to replace a broken intake bolt. When on my bench top I had to removed the J-Tube in order to replace all the bolts. What I noticed is that I only removed (5) bolts where as the J-tube has (6) bolt holes. Would someone be willing to take a picture or explain to me how the bolt nearest to the intercooler inlet on the passenger side is mounted? The M8 x 25mm bolt will not go in due to the radius of the tube but I was wondering if a stud and nut is how it is attached. I have been fighting idling issues ever since the install and I can see how air would have leaked in through this void since it has never been secured.

 

thats how they come mine was same way just use anarobic sealant on faces and bolt back up

 

I'm wonder for peace of mind if I should machine a plug and epoxy in?

 

Can you post a picture of what you are talking about.

 

seems to me when i removed my 78mm j-tube there was a hole not being used near the bend, and with the 90mm j-tube it had one less hole then the 78mm

 

Here is the hole I am speaking of.



The previous owner of the supercharger made a plate and had it heli-arced onto the original J-tube. (the picture attached is not of mine)

 

Don't bother trying to put a bolt there. Clean both surfaces really well, and get a tube of anaerobic sealer. The 90mm J-tubes only have 4 bolt holes, 2 on top, and 2 on bottom. Only pic I have doesn't show all of that flange, but you get the idea.



Sealer...
