Looks good! You can use a borescope through the throttle body to look at the inside if you really want to.

Ah good idea! Thanks. Im not really too concerned about it. I'll take pics once I cut it in half to port.

I would also be interested in how it holds up in the long term.

The process is more of a fusion process.

If you could obtain a spare for this process, It would be cool to use a second intake to cut the patches out of to fill the holes and get a better fit.

I have always wanted to cut one of these open. At 1 time people were practically giving these intakes away.

How the heck would one of these be ported?

i'm sure if he was after all out performance, he wouldnt be modding a truck intake. more for looks, and it looks good.

i would be afraid to put boost or nitrous to it, but it's hard to say without actually seeing the test piece that you melted together. it may be fine.

at idle, if you grab the throttle hard from idle to redline, does the intake flex or buckle any? i think all of the ugly extra plastic was there for rigidity.

I'll keep everyone posted on how it holds up. Even if my projects fail, I post up so others can learn from it as well.

Another reason I think it'll hold well is because this "fusion process" is probably better then the method they used when they made this intake from the factory. I say this because when I popped those circle ports off of the intake, you could see that they were just heated and stuck on. Just a small ring fused to the intake to hold it on. Im actually mixing the two together. Wish I had a pic to show how it was done at the factory.

All I can say this stuff is strong. Read my last post comparing how it was assembled/fused from the factory. What I have done is stronger. I punched each of these pieces after welding and see zero flex. It is solid.

I think the intake see most vacuum at idle. So every time it idled would be a test.

I'm thinking about mounting it onto my extra motor and riging up my air tank to it to test 20lbs of boost. lol
