JM Fabrications

[Halon]

oh really. I guess I didn't know. I just go by their website and they don't have anything in the Intake Manifold link. So I figured it wasn't out yet. Is there any info you can provide on that one by chance? pics? impressions of it?


Oh I just found this!! Guy is making his own . I'll just follow his writeup, im sure it'll be a solid design for sure!!

I do have a different design, just need to find a little time to get to making the new ones. All the parts are in hand, new tooling in place etc, just nine motors, 4 O2 housings, several heads and a few cars holding it off. Maybe in a week or two I can get to it again.

The website is pretty gay, i need to do a new one. The manifold on tuners is just lovely, looks like something tom would build. If tom could weld or do anything productive that is.

Ya I noticed a lot of the links on the site don't have anything. Just too swamped with things I'm guessing. But please if you have any info or pics or price range on your manifolds, please share. Also can someone fully explain the "venturi" design? Is it just the kinda of rounded trumpet lookin ends on the velocity stacks? Or do the runners shrink and open back up 3 inches into the runner or what? I hope that made sense. I'm under the impression the purpose of it is to speed up the air against the walls, so that air isn't moving that much slower on the walls then the air in the middle. Is that about right? But the design on how they do it on these manifolds is what I'm kinda not crystal clear on.

I wouldn't get too excited about that guy. There have been probably 5-10 serious people in the past couple years on Tooners who were all about building there own manifold. There was even one guy who claimed to have been working with some local engineering firm and had consistent access to a dyno to refine his design. As far as I've ever seen, none of the manifolds ever amounted to anything, including Mr. Engineer & Dyno.

Ya I was joking about that guys design on tooners. I am all about fabricating things like my own fmic piping, intake pipe, things like that. But when it come to things like intake manifolds, I think I'll leave that to the pro's because that's just a whole different level of fabrication in my eyes.

AMS is working on some awesome designs. And they are probably the only people out their actually testing their designs on a dyno. Personally, I think you could do just about anything with a decent sized plenum and short runners and get a good power gain, the stock intake manifolds are so anti-topend power that just about anything works. Look at my pos old school Magnus, it is held together with silicone couplers and the runners don't even line up with each other. With it on my 2.0l, my power didn't start to drop until 8300RPMs, compared to 6500-7000RPMs on a stock intake, and it has made 660whp so far on my 2.4l. To get something special enough to blow away a basic design would take a lot of work and testing in a controlled environment on a dyno.

So general consensus would be that this JM guys manifold seems like it would work alright then? Thanx for everyones feedback. I'm going to keep a lot closer eye on it, because it would be nice to see someone post up some numbers on it sometime. I'm not getting one tomorrow or anything, but will be in the market for one after I first get a few other small things, like another rear camber kit because taboo ran off with my money.

... taboo ran off with my money.

Sorry for the off-topic but supposedly Martin had f*cked up his back but is now back in business trying to get everything caught up.

[Halon]

ya, look on Vendors-Reviewed.com He is supposed to be back and getting everything caught up, but he still won't answer any of my recent emails regarding my order placed in August. My address has changed since I placed the order so he he would prolly ship it to the wrong address now. I try to inform him of changes, but he won't write me back at all. My worst vendor experience EVER. But ya, how bout them intake mani's!!
