painted up almost ready to go on...epoxy or no epoxy...that is the ? have one with i can cut it up if i like the new designed runners...there much shorter then whats on the truck now...decision's,decision's:crazy:
will be interesting to see how far up the very short runners move the power band, assuming you are going to dyno it.
I only took 1.5" off mine, that looks like closer to 4-5" by the pics.

yes it will be put on the dyno....tried to cut them in a way to retain the oem cross section of the runner....i noticed when cutting at an angle it open's up the CS...smaller CS promotes low end performance...shall see...thinking iam going to pour this 1 to

yep painted oem stocker fuel rails...steel not plastic but i have read of some being plastic

Has anyone ever tried to cut our kegger intake with a plasma cutter?
I have been using one at my shop on the scrap cut outs from the divider and it seems to cut real clean.
There is a little slag that chips right off.
Just wondering:IDEA:

I think you may lose some low end, but it will be offset by the gains.
I cut mine down about 1.5 inches, tapered them, smoothed the injector bosses, etc etc. Took about 10 hours total time with the deburring bits & polishing wheels. Gained torque & hp across the board according to the MD-1270 dyno. I don't remember the exact amount, been concentrating on my other project lately.

cut the runners as short as possible. the objective is to draw air from more of a direct route, and to open up each mouth. i buzzed mine down flush as well as cut into the shared divider way further! too much around the corner turbulence in there!

i opened the tb port also. actually cut so much out & joined the holes in the middle. the m1 intake is just one big oval.

Dont know if anybody is still talking about welding aluminum (cant remeber which thread I read it in) but theres an episode on Extreme 4x4 on this. May be worth looking into, gives several ways of doing it with even your standard 110 volt welder. Just takes some different techniques.
