relief welds on manifold
 

as title says....

what is the best equipment to use to make these cuts?

just picked up my greddy kit and the cuts have not been done.

after its done.. i guess itll be in 3 pieces?

Search. Hacksaw. Might not need to do them.

an air cut off tool would do it easy.

Chop saw, hack saw, abrasive hand held cut-off wheel. About anything will work as long as you can deburr the cut when you're done.

oh ok.. and does it come out to 3 pieces like the pic above?

It won't be three separate pieces but the runners will no longer be attached at the flange. You're simply allowing the manifold to expand and contract more freely by making the cuts.

around...

1/8" for the width of the cut?

yeah

Width shouldn't matter, as long as you cut through it. But like I said, you might not have to cut the manifold if you have a new generation greddy manifold.

Mine was cut by the PO, and is currently warped to the point where I have no idea how I'm going to get it off. That's what she said.

make sure to wear gloves and safety goggles

Fuel/ air bomb, make sure everybody around you is wearing gloves and safety goggles.

Walk into a harbor freight and hit the air tools wall. 1/4 of anything on the wall can do the job for cheap.

ic.. curly how can i tell if its new gen manifold or not?.. ill try get a pic up and my setup...

can't use air tools.. i do not have a air tank~...

either going to buy a hack saw.. or buy more blades for the dremel!

If it's a hack saw, use lots of used motor oil to lube the blade.

Or buy a $15 angle grinder from HF and use one or two $1.99 cut off wheels for a much faster and lazier approach.

No I cannot tell if it's a new manifold. I just know that there were chronic issues with the original that required relief cuts, and that eventually people stopped doing the relief cuts and they were fine, indicating a design change.

If it's used (as it appears to be) and it's survived this long without cracks, I'd just leave it alone. However I assume no responsibility.

icic.. well i rather be more conservative.. and just do the cuts.. my first setup.. so i want to boost a bit before.. getting broken parts = buying more parts

I have no idea what you just said. Good luck.

I think that he meant, Better safe than sorry? not sure
