Anyone know anything about this company and it's products? He has what, to me, appears to be a decent smim for a very decent price. It does have a tappered plenum, as well as velocity stacks. What about venuri designed into the runners? It doesn't say anything about that, so I'm guessing it doesn't have that. I am no expert when it comes to this so it'd be nice to hear what everyone else has to say about this.

Browsed the whole site; products look decent however I have never heard of them. And the $450 price for the intake manifold isn't all that great without a proven name if you ask me. I like there roll cages though, I didn't see a price on them but the welds look good and the fitment looks good as well.

I don't know what to think about the water to air intercooler project. Good idea, but looks to be a lot of work with the cutting and re-welding of the passenger side fender well.

That design actually looks pretty solid. It is pretty similar to the ones I might be making. I have come up with a pretty cool design, but I haven't gotten prices yet. I hope to be in the $400 - $450 range.

Jim's products are growing in popularity quite quickly. From what I remember, his name and products have really started showing up around different boards within about the last 6 months. I have yet to read a review of his products that is anything but 100% positive. I've seen pictures of his heat shield on a few different rides and it looks great. With the price of the Magnus increasing, the weld-blowing problems of the Venom, and the number of people downplaying the Forrester (SLS for one), I can definitely see why his popularity is growing.

It doesn't look bad for the money.

Yeah Jet and I were just talking about them. I think that developing a intake manifold is kinda like re-inventing the wheel. Yeah you might have a cool design and a good look. But when it comes right down to it, people are going to 1) buy one that is proven that costs alot of money or 2) buy one thats cheaper but probably does close to the same thing. But if you are planning to develope and intake manifold, something cheap, durable, and a good price is the way to get a name for yourself.

Ya I've just read about their intake mani's. People seem to be saying they like them, but really no numbers or anything. Just hear-say which doesn't amount to that much. But I guess to me it still looked fairly decent. I'm going to be in the market for an intake manifold and am just trying to see all my options. The Magnus seems to really be one of the top performers from all my reading i've been doing. But 700 bucks, that's a lot of money and a semi-large investment in my books. Not trying to cheap out, just see all my options before dishing out that money. If the others out there quality just doesn't compare, then I will just have to dish out the money. But I'd like to cover all angles first, and this manifold caught my eye. I'd still like to see if QPR ever comes out with their design. And what kinda price range that'd be in. *cough* MIKE *cough* j/k man!!!

TheBlizzard · 02-13-2005

QPR has a design for an intake manifold. Its on a car in our driveway. Unless Mike has came up with something else since then which I am sure he did.

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.

**Halon** · 02-13-2005

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.

**Halon** · 02-13-2005

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.

**Shane@DBPerformance** · 02-13-2005

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.

**Halon** · 02-13-2005

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.

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** · 02-13-2005

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!!
