Can you post the test results for the Z1 and M370?

He has a thread in this forum about 6 pages long with all 3. He chose the Z1 mani and sold his ported M370 and regular M370.

Here you go http://www.the370z.com/intake-exhaus...d-testing.html

I like what the future holds. GTM, Doran, and CJM all have intake manifolds in the works. Let's get them released!

Thanx man! :) not entirly true tho, I still have the ported M370 and another regular one . The ported one I decided to keep. LOL I'm thinking of putting the ported one the car after the 6th of June, Dyno with Z1 and ported lower.

The only hope on that list is CJM. GTM will never release theirs and if they do they going to have to give them away for what they did to people :icon14:

Thanks for the link.

In the car with these mods the M370 has more area under the power curve and I would expect it to accelerate more quickly than the Z1 through the gears.

I had the m370, it did nothing statistically on the dyno. The Z1 did. It was several years ago, so I don't remember what the specific gains were, but I'm putting down 342 at the wheels with CAI, intake, exhaust and tune.

and good luck getting Charles to even let GTM even see his manifold, and for good reason.

342 that seems a little high. What kind of dyno did you get tuned on? People with headers have trouble reaching that hp level. With that set up people are usually putting down 320 ish.

The M370 made more under the curve at least what I've seen 10+12 more wtrq under the curve and the same WHP up top Vs the Z1 but we'll see about the Z1 after I get a tune for it. My comparison file was with a Etune for the M370. It's all in my thread here

Because they would laugh at it? lol It may be unavailable but their manifold was the **** let me know when CJ's Mani gets you 26lbft at 4000rpm on an NA car and will do 400wheel at 8700 rpm.

no, because they would copy and steal it.

why they have a better manifold they just need to make it.

I wouldn't be surprised if they trash can the gtr setup alltogether and and just boost the current one thats what I told Sam to do.

Time will only tell what cj motorsports manifold will do

They? Why do you keep saying they when you worked there, designed that manifold... And are probably the same ex-GTM employee that called me trying to sell all of GTMs CAD files when your paychecks were bouncing?

Cats out of the bag, keep it real. Sam finally lining your pockets again? Must be some reason you came back after having to sell your car.

Did i used to work there? Yes Did I design the manifold? part of it yes there were 2 other guys involved. Does Sam line my pockets? No I stopped working there last fall. I'm not biased in any of this if somebody wants one of the parts off my car they have to call Sam I'm not going into the success of that happening as enough has already been said there but no one else makes it just a fact. Are we really gonna go into dragging up the manifold **** again? You and I already talked about that a year and half and an entire thread ago when the word masterpiece came up, and came to a conclusion that we both have valid points and that you're manifold is targeted to a different compromise of 370z applications. I agree with you that the GTM manifold is not serviceable and is a lot more expensive due to different throttle locations, different fuel rails, different component locations, difficulty to manufacture, and the one you didn't point out, it runs right through the factory oil cap neck. WIll it hands down perform better than yours? Also a yes because you are still retaining the worse piece of the factory setup. have you seen the cfd on the factory lower when you transition it into an open upper bellmouth? it's dogshit. is it an utter PITA to design a working replacement for that piece that incorporates the convenience of the oem piece and allows you to hit a price point that will actually let a large number of people purchase the manifold? yes. Is one manifold black and the other white?

I am 200% sure your manifold will be more Successful, but the GTM Manifold was awesome for it's no holds barred all out focus on getting air into the heads. Frankly it was a ************ to assemble there are like 52 god damned bolts, 24 o-rings, 6 gaskets, a crap ton of hoses, extended wires, you have to pull the valve cover, and it takes about a day just to put it together, but it does make power.

Thanks for pointing it out that I worked there, don't know about the rest of the stuff but I never said i didn't work there hell a bunch of guys here know. I was never biased even when I worked there, I have plenty of time in this game and I call **** as I see it. I give you props for finally getting your own cnc's and building to the point you are at. It must be hard to run a business when your parts supply was coming from a friend of yours making it after work at the machine shop he worked at. As for your conflicts with Sam I know its a two way street between you two but I made no decisions or had any relation to anything that went on between you two or anything business chit at GT I advised Ron the engineer there on parts, pushed buttons, and towards the end of my term I put together as many customer cars as I could to get them out including the white dragon.

I have nothing against you and I didn't get all personal. I stated my educated opinion on facts about a hardly existent alternative you could have put up or shut up but instead your all in on personal defamation true or untrue. since this is gonna get cluttery you take your post down and ill take mine down and we go to pm's if you want to go at it all keyboard ninja style.

I'm back because I'm building a VQ40 TT 74 260z and soon I will have business being back on here. I bought another car deal.

All sounds good to me... I dont really have anything to add to the conversation for now if you'd prefer it doesn't continue. I just didnt like the underlying negativity you were posting, and I felt the urge the interject for the purpose of broadcasting why it is you have a pride-fueled motivation to strongly dislike alternate intake manifold projects. I can relate as I instinctively dislike yours for the same reason... I just dont barge in and make negative comments about it.

As for my accusation you considered defamation... if it wasnt you, than I retract the accusation, and its just a random interesting fact that someone did phone me with such an offer.

I wouldn't dis believe it I did I hear it got pretty bad there for a while and few guys did leave all disgruntled like, one even stole a few thousand dollars worth of stuff, apparently its better now but I have moved on with my life and as a boss I broke with Sam on good terms. The build on my car got a little ridiculous cost wise and disenfranchised me with the whole car game for a while but now the mod bug has bit again and in the immortal words of that drunk guy at the end of independence day HELLO BOYS III'MMM BAAACK

I'm not really negative of it as competition wise, I'm negative of it as there are things you could do to make it better while not increasing the costs. I know running a company your time is limited and you can't afford to work on something forever without getting paid but i'm sure there is something you can do to improve the manifold.

Well give me a chance to finish it before you dislike it too much... youre looking at CAD renderings from almost a year and a half ago when I was just excited to have the flange and some constraints in CAD

sent you a pm, the first idea in it is meh, the second two are intriguing. hell you're only one state away from the second one.

Well got Lieutenant &$damn!!!. Why don't you two just put your minds together and come out with a useful manifold. Id say squash the pork and work together. Hell I'm in Florida and all this Chinese Manderin car talk about runners into open necks is way beyond my scope of knowledge or I would fly there to help out. 1slow370z as much info as you know about the VQ set up seems as if you were an engineer at nissan that help develop the motor. Work together and let's see something magical come out of this. Cost is irrelevant if the product produces power. I'd sell my girlfriend to buy the part if I had to.��

Dude - this is all done .......... lookie here:

Manifold : Manifold Nissan VQ35 -SF - Jenvey Dynamics

If I was interested in looking closer, I suspect this is the pattern for 1Slow's manifold, except that he installed spacers in place of the ITB's and CNC machined a f4rking great plenum for each bank and plonked some 75mm TB's from a Maxima in front of each.

Ummm yeah... This is meant for a cable driven car and not drive by wire... which means you would have to go standalone ecu and revert back to cable driven system. We have known about the jenvy kit for some time. thanks for pointing it out though.

Speaking off topic for just a second. I heard going to a standalone for ours cars, would not allow our cars to pass emission's?

You are correct. The current standalone ECU's do not offer OBD2 Support. Hence they have no OBD2 port.

Emission Testing for OBD2 (1996 and later vehicles) requires the emissions tester to plug into your OBD2 port and run diagnostics. Without the OBD2 port you cannot physically pass emissions.

Wired and installed accordingly, you would be able to pass an OBD2 inspection.

Although, you dont have to worry about standalones, there is no true standalone that is proven and tested capable of running the VVEL system (not that I have seen yet). I am sure someone could spend a fortune and get a Motec to do it, but I am not aware of it ever being done.

Dynosty can set you up with a Haltech PnP piggybacking the stock ECU, it will run standalone fuel and ignition tables, with the stock ECU running VVEL and OBD related stuff, and shouldnt have a problem passing emissions.

Something I could look into if I ever max out the use of uprev.

The only thing the same about them is they look similar because we originally were buying jenvey throttles for our itb setup. The runners are different. Jenvey runners do not fit the vhr motor

Actually, Jenvey now supply a stepper motor retrofit kit for their ITB system, so you are not forced to go back to a cable to pull the throttle.

One of my race buddies has a Jenvey DBW kit running on a 5.6 litre TVR Tuscan racer here in Oz, all controlled by a Haltech Elite ECU - is early days yet as the Haltech is still a tad buggy, but it is the way of the future as we have total control over throttle position, ignition and fuel and with yaw sensor and steering angle, the next step is driver alterable traction control strategies.

FYI, Motec are already controlling VVEL with M1 series ECU on the VK50VE engine.

Aem infinity is more impressive than the haltech to me.

Fyi that motec unit is still $16k in parts

Nope. I need to find a sugar momma.

Things we already know

Honestly, I think it may be better to have a manifold that keeps the torque the same and utilizes high end HP gains. This would greatly benefit those with high HP FI builds, either stock or built. People would be able to hit higher numbers with the higher HP and same or lower torque and that would keep reliability up.

IMO, a little bit of torque wouldnt really benefit anyone for the money they will spend on the manifold, especially in the low 300whp ballpark.

Punk could you have custom throttle bodies fitted to the manifold (special request). I would like to fit 68-70 mm to the manifold and do custom 3 inch intakes with velocity stacks.

You might want to look at what the GT-R guys are using. Since the throttle flanges are the same, you could use some aftermarket GT-R throttles. I wont be playing with the throttle bodies.

Cheers

Is this project on hold?

I think so with the new oil pan coming out.

I wouldn't think the oil pan would hold anything up. Its just another project like the fuel rails.


I do wish we could get a status update every so often though.

Same here. Busy man. Hopefully it comes out sometime this year, or maybe he is testing or redesigning the manifold.
