My 4" Dewalt angle grinder and a 40 grit grinding wheel ate through those runners like they were made of wood. You just have to be REALLY careful you don't nick the plenum gasket mating surface.

I might have aluminum lung disease as an end result.

 

hell yeah

 

Hey Silver you mentioned updating the pics in my thread. Could you do that please. I wanna maybe do this mod this weekend.

 

I just got back last night from business travel. I'll try to do it tonight when I get home from work. Sorry, just been really busy.

 

Pictures have been added back. Hope this helps.

 

Thanks a lot that helps a lot.

 

No problem, sorry it took so long. So did you work on it this weekend?

 

Nah not really. Looked at it last night trying to figure how much to take off. That one that pc posted from ebay said he took 2" off. I don't see how thats possible. If I took 2" off mine I'd be into the other runners so I'm thinking about an 1 1/2"

 

Ya, I struggled with how I should do mine too. It's hard to decide how much to take off if you plan to cut the runner parallel to the way it is currently shaped. That's why I chose to do the angled cut instead. That way, the back wall of the runner is still the full length it was from the factory. Air entering the runner is going to swoop down and hit the back wall of the runner before turning up into the runner. By keeping the back wall full length, it is essentially a tricky way of actually maintaining the full runner length (which is said to help low end torque), but instead opening up the overall opening size of the runner to facilitate better/more flow into each runner. I am very happy with the performance of mine. Wish I had dyno's before and after though.

 

Nice work man, well explaind. my plenum plate is leaking on my 96 5.2 and i cant find an m1 for a reasonable price so im gonna go ahead and try modding my keg ao im wondering how it worked out for ya? and was indyramman right about cutting them square?
