I have thought about doing this. It would be pretty tough and I think you would have to be pretty good at welding. It wouldnt look too good. I do however think it would be a great "bang fot he buck" mod, because it wouldnt cost you anything. Plus you could siamese it all of the way down. I just decided to buy a set of used SLP runners instead and do some pretty good porting on them. good luck if you decide to try it

I considered doing that...but I found a deal on a super-ram instead. Someone suggested that I use high-temp solder(not certain that will work when the engine get's hot). I have a perfect set of TPI runners, and don't want to butcher them, but I may try it if there's enough interest and if I can find a POS set of runners and a plenum. What do you guys think?

A guy here in SoCal tried it. He used fiberglass to siamese it. I cant find his pictures, but it was a failure.

Did it, tried it, didn't like all the work that I had to do at the bottom to splice into the common area, and to merge the top together. It is NOT an easy thing to do when MIG welding the bastards!! Probably would have been a tad easier with a TIG. If I had to do it again, I'd rather fab up some out of mild steel.

I know it's difficult due to the thin matal, but I have access to a complete shop full of tools at work. I've thought of doing it, but may give it a shot for everyone's benefit. I think it comes down to being careful and using the right bonding materials. I know TPI's has done it, but the d*c# wouldn't tell me how. What do you say? Does anyone want me to try? If it works, I could post it in the tech articles section. Let me know. If there's enough interest, I'll do it.

Re: siamese stock runners ?

There was a guy on here that did it with rad repair rods. I'm more curious about the #s before and after tbh because I wanna try it myself. I mean hell it may be a lotta work but you have either time or money so if you can do it for next to nothing versus 4-500 for a set of runners it'd be a great deal IMO. The next step of course would be figuring out how to jig the setup to make it doable a lot quicker and sell em or lend the jigs out for a fee/deposit.
