JRSC Welding Question
I bought a Jackson Racing Supercharger used and it has a crack in one of the bolt holes. I'm not sure how to fix this. Would welding the crack up then rethreading it work?
I won't be doing this cause I never even held a welder so how much (ballpark) would someone charge for something like this?
Thanks guys. I appreciate it!

Drill out the hole so no crap is stuck in the threads, die grind off the damaged part so you have a "divot" of sorts.
Build up the die grinded area with weld
machine and retap/heli coil.
I estimate it would take me < 30 minutes.

Re: JRSC Welding Question
As essex said, I'm quite a way away from you, but for the record, I'm a welder/fabricator for a radiator shop here in New Zealand making custom radiators, intercoolers and oil coolers for performance/trucking/heavy machinery
I would preheat the whole housing in our bake oven, too. That atleast would minimize the risk of it warping. Although, I've welded tons of gearbox housings/intake manifolds/blower manifolds and never had one warped yet.

I would not worry about the warping right off the bat. Soon as you hit with head it needs to be planned flat again.
Ive got a manifold that cracked in the same area.
I would grind it down make a channel down the crank and passed the Crack. Then have someone tig weld it. Then i would have someone plane it. You can also do it with a belt sander and a straight edge. Then re thread the hole M8x1.25 with a bottoming tapp.

Re: JRSC Welding Question
I had the same problem with the one on my Integra (when I was twincharged), but on two of the threads. I had the luxury of having a decently powerful welder and was able to weld up the crack without putting much heat onto the entire casing. I used a gold tungsten, sharpened to a fine tip to focus the heat and welded it up really quickly before the heat spreads.
I sprayed the housing with water and soaked it with wet rags to keep it cool. I used a small drill bit and drilled a hole at the end of the crack, and used a die grinder to widen up the crack for better weld penetration.
After I welded up, I actually drilled out the old threads and heli-coiled it. It's stronger than before, and had no problems even after several times of disassembly/reassembly.

Re: JRSC Welding Question
woah! that sounds pretty intense. I'm gonna take it to someone, I suppose that it would be best to take it to a fad/welding shop.
