Just wondering if anyone has gotten the variable intake on there car actually?? Because I understand like 3-5 people have ordered it and gotten teh variable manifold intake. And I was just wondering if anyone that has gotten it has actually had the time to put it on the car. Because I haven't heard from anyone saying that they have done so and if it is worth it. Because I'll be having a tax return coming in, and this is a mod I'm looking at buying and wondering if it is worth it!!!!

 

It's more complicated than just slapping on an intake or an exhaust. It's going to take time for them to work out the details.

 

since i have no money.. if delio or coolkids gave me theres to test i would slap it on and dyno test it.. but they both like to sit around and watch it collect dust

 

I don't believe that......

 

i am dating 8 wimmens.. i am running out of cash dude i had to make a trip to the grocery store and cook sunday because i blew $60 on another on Saturday .. i guess my cousin is right.... i do date high maintenance chicks.. but then i don't want any ghetto girls

 

I'm the one with no money. I'm back with the lady and we're getting married.

 

congrats my friend i envy you

 

$60 for a date on saturday? and you are thinking that's high maintenance? I usually spend $300 for a date on sat.

 

If I see some significant gains from this intake then I'll buy one. I have the money to buy one but I'm not so rich that I can go spending money on a mod that might not be all we hope it will.

 

you spend $300 on a date .. when you got 5 dates in 5 days..

 

I think that if the butterfly valves close off the alternate plenum under vacuum, that it would be a simple matter to connect it to one of the manifold vacuum lines. Still, a purely vacuum actuated system does not seem as good as one controlled by factoring a variety of engine/load/rpm inputs. For instance, if you are launching or at low RPM and then jump on the throttle (WOT), the manifold vacuum will suddenly fall and open up the second plenum, but your rpms may not be that high (5k+)... That isn't ideal. Ideally, you want it to open at high RPM. I don't know at what pressure the butterfly valves open though so this is all just conjecture. I haven't gotten my manifold yet, but some vacuum line tests would be interesting. I may get a Mityvac to do that...

 

You guys think you have no money? I work part time bagging groceries for $7.00CDN an hour while going to university.

 

But you own a 911.

 

O(ff) Topic - Really? Congrats bro!

O(n) Topic - I wish ppl would hurry up and see what kind of gains this intake will provide!

 

then tell all the ***s who bought it to get off their as$

 

It was an extremely generous graduation gift from my parents, which I was hesitant to accept.

 

whats up brother..

 

yeah that would be too much money, that's why I go for quality rather than quantity.

I bet the intake works best with the Y-pipe, I dunno if they have precats in Bahrain, do you roadbeast?

 

Can they adopt me?

Please?

 

Has anyone installed this yet? I want to get mine...

Thanks man!

I have no excuse for not getting the thing on ASAP. Even got the upper-to-lower manifold gasket from the dealer. From the available pics, it looks like the only difference is the vacuum inlet for the butterfly valves. First day off I get it will be going on (after it arrives).

 

By looking at it or what not how big of a job do you think it is? Are you gonna do before and after Dyno tests so we know actual numbers instead of just "it feels faster" ?

I Can't wait for the results. I'm sure it will be big noticable difference. Just can't wait to find out how much.

 

The job is strictly an intake manifold removal and replacement job. That includes taking down all the stuff bolted to the top of the manifold, two coolant lines, vacuum hoses. I am hoping I can save some time by leaving all the coolant tubing, and even the intake stuff (CAI) on the tb intact. Then the IAC port/sensors need to come down, the EGR guide tube removed, two bolts in back and the ones in front. I am thinking, based on the size approximation from Roadbeast's pics, that the vacuum line underneath the TB may be a good place to t-piece the butterfly valve vacuum line. In all, I'd say 3 hours, barring unforseen mishap (which always seems to happen with me).

As for testing, for now, won't be doing dyno's. Maybe after I confirm that it is working like it is supposed to... but I'll probably be assuming typical baseline results for a car in my condition. Like my Y-pipe, I like to rely on the butt dyno. I don't go to the track or race, so to me, if I can't feel it, it may as well be not there...

 

Hey that is good enough for me...if you can feel the pull...that will work for me. Because I'm pretty sure everyone that has it is going to notice a noticable difference.

 

Would there be anything else to rep[lace while your at it? I mean alot of times once people have everything opened and exposed they change gaskets or other things just so they wouldnt have to worry about it down the road. Is there anything like that under there?

SuDZ

 

Well, if you want to be complete, order a TB-manifold gasket, IAC-manifold gasket, and EGRtube-manifold gasket (in addition to the upper-to-lower manifold gasket I mentioned). Definitely, you do not want any leaks! The bolts for the manifold, TB, IAC must be torqued in specific order to minimize leaks. Otherwise, i don't see anything else that needs to be changed. I guess while you have the upper intake manifold off, you can clean as much of the lower as possible.

 

Cool. I was just kinda thinking of things that people might wanna check out while under there. Not sure on the cost of theese but alot of times it cant hurt. Also on a lot of "just in case" things like this you never have to worry about it again. I myself have never removed the manifold but figure if this shows some gains then if I go for it just wanna know ahead of time if I should do anything else.

Thanks for you help.

Why would you want to be my brother when you have your very own Carrera 4?

You'll have to bring it down to a big NE meet then.

 

Yeah. I've taken off the TB and feel that reusing it's gasket over should be no problem. As the the lower-to-upper intake manifold gasket is somewhat compliant rubber, I'd thought it'd be wise to at least change that. $4 and the dealer had it in stock.

 

please keep us updated mishmosh. this is pretty exciting.

 

umm... dude.... that would constitute a hooker... are you getting any.. hope so..

 

Sadly, no. It is "on hold" in New York. Called DHL and they told me that it is going through customs. They did say there didn't appear to be a problem so it's usually 24-48hours that it is there.

Went to Autozone to see if they had a vacuum guage. Nope. They did have all sorts of rubber tubing and T-pieces so I picked that up...

 

actually, $60 will get you a hooker, $300 is what you'll spend when you date a marketing manager for IBM. sorry, wrong board.

 

my portfolio took a big hit after 9/11 i sold all those exotic cars except the Maxima and the 360 Modena

 

*** boy is in VA for school.. he should stop by on his way back to Canadia

 

You will probably feel it the most at the top of 4th and 5th gear, and maybe the top of 3rd as well. If your car still pulls strongly past 120 mph in 4th, then it's working In 5th, your car should top out at a considerably higher top speed, and it would pull strongly past 130 mph to top out at like maybe 148, on straight flat road.

So you dont think it helps as much until higer speeds? Above 120 or so? I was hoping that this would be something that could be used throughout the power band. I dont really need the extra go at above 120 as much as I would love having it like above 60 or so. It would help more oon 1/4 times and just general driving.

SuDZ

 

The power boost has nothing to do with mph, but has everything to do with rpm. The variable intake will only add torque past 5000 rpm, where the US 4th gen motor pukes out. This torque increase at higher rpms is where the significant HP increase comes from.

You will not feel any difference below 5000 rpm. You will feel a LOT of difference above that, especially at 6000-redline.

But yes, you will definitely feel a big boost when winding out 3rd gear (past 5000 rpm). If you're winding out 4th and 5th gears, you should probably be in jail.
