3.2 VR6 OEM+ intake manifold project.

[need_a_VR6]

Don't forget there are going to be more and more swaps done as those engines become more readily available.

Josh/Cosworth,
My wishlist is as follows:

-Keep the price under $1000
-More durable than the stock version (mitigate the risk of ballooning/popping under boost)
-Retain dual runner design
-A little more power -- wouldn't expect more than 5 BHP
-For insiders: allow me to laugh in the face of CVP owners

-Brian

[newcreation]

Ill spend over 1k for a good manifold with positive results.

[PowerDubs]

Hi Brian,

I'm not Cosworth, but I'll give you what I think the answers would be-

-There is no way they are going to produce a cast manifold that retains a dual runner design for under $1,000.

-I'd assume it will be cast aluminum so it will be strong.

-If it isn't dual runner than I don't want it. There are plenty of people willing to fab a single runner length manifold for cheap..but that has a lot of drawbacks.

-I'd imagine 5bhp will be no problem at high RPM with larger runners and a larger plenum.

-I'll bet $10 the minor grinding of the short runners I did to my stock manifold with a dremel and some expoy will have better results than the CVP (if it holds together)

- Josh

Copy lol.Hope this works out.Also hope your manifold holds together

[mk3gtidriver]

I'm in on this. While a budget minded manifold would be nice, it's not realistic. We all wanna make more power. As PowerDubs has shown with all his hard work and time, this is the next step and one that will require some more time and work of a company such as Cosworth. Hell, non of the power mods for our cars are "cheap", especially when you want quality to go with it. Hows that old saying go "If you wanna play, you gotta pay".

[Draxus]

Three options for anything to do with cars:

1 - Fast
2 - Cheap
3 - Good Quality / Reliability

You can only pick two.

why so excited about the cosworth manifold?
it didnt seem like great gains on there website.
im not being a dick im just trying to understand what that set up would offer. is it the idea that it will let other mods make better use of their power? ie let headers or ported head have larger gains.
i understand that its all about making the package work but for 1300 bucks on a manifold was was hoping to see the cosworth manifold making more gains....or was i blind and reading the graph wrong?

[PowerDubs]

Anyone else want to field this one for me?

I thought about it a few minutes ago but i am getting tired of re-explaining everything when its already in the thread

I agree

[DannyLo]

I want one for a 2.8 24v!!!

They're different heads (most of you know this, just wanted to post for information)

ie: 3.2 intake manifolds are not interchangeable with 2.8 intake manifolds, although many other parts from these engines are.

VQ35DE in RWD/Z33/V35 configuration has a single stage intake manifold, its hard to improve low end characteristics of an engine w/o using a resonance chamber or dual stage runners. This intake makes the engine breathe on top end, stock VQ cams are weak to begin with. Gains shown on top end clearly show ya what can be made given more RPMs. I did some diggin and the car in question had a raised rev limiter in order to show gains to be had with a ECU flash- like one from TechnoSquare.

3.2 VR isn't like a VQ35, their similarities are- both have 6 cylinders and 24V. Don't base your findings off one engine, what works on a VQ might work even better on a VR. VQ was a tough engine to gain power on NA to begin with. Most of them struggle to gain 30WHP NA w/o crazy bolt ons and high CR pistons. We don't know how the VR will respond to a new intake manifold, but we hope it will work with great results.

Don't forget this engine is used in the following cars-
VW R32
VW EOS
VW Touareg
VW Phaeton (overseas)
VW New Beetle RSI (overseas)
Audi A3
Audi TT
Porsche Cayenne
YES Roadster (overseas)

You just have Forgot the VW Transporter T5 V6 and it's family the Carravelle, California, Multivan....
I would be intrest by one of those manifold for my T5 V6 4motion.

PowerDubs, can you make sure Cosworth gets this info? I don't think they realize how many vehicles use this engine.

[surffly]

so it is belived that the gains will be better on our motor because of the two stage runners?

what do you mean about its been explained? the idea of the cosworth manifold was only just brought up. also i understand that people like powerdub are working very hard on a project like this so there must be something to it. all i was saying is that the graph for the vq35 motor wasent as much of a gain as i would have thought, not peak or over a range.

Those gains i believe were on a stock motor with out any loses.So you start adding parts and a tune you then have a manifold that can take the flow of the upgrades

I don't know why people keep refering to 'the cosworth manifold'.. the discussion is about making 'a' cosworth manifold.

There is no cosworth manifold for our cars, and if they ever do build one it will be completely different than the nissan one and the results will be in no way comparable.

I only posted the nissan part as an example of the quality work they are capable of for people that were not familar with them. That is where it's contribution to this thread ends.

So poeple don't get what we are doing and trying to achieve here Josh.

[surffly]

i see what you are talking about now.
very cool and a big thanks to the guys that have the means and knowhow to do this type of work.

anyone have expirence with a rapid protype tool? we have one hear at school and the guys on the FSAE team were able to make a very cool intake manifold for the car. its a 600cc motorcycle motor running a restictor the size of a quarter but still makes 80hp
it would be more money for the first one but could be made with exact specs and be made rather fast
just a thought

[Draxus]

I could totally make up a model in Solidworks to have made. Just no access to a machine.

Feel free to make a model.. we like pretty pictures.

[Draxus]

Do you have dims for the manifold? I am still hunting to a R32 to buy that hasn't been raped by the previous owner.

Jesus, I am making a aftermarket part for a car I don't have yet. haha

[PowerDubs]

Nope..no dimensions, and once you get one in your hands and look at it closely.. this will be no easy task. It is a very tight fit in numerous locations.

[Draxus]

Didn't seem that bad from when I looked in the engine bay. Do you have a VW document with any kind of pictures?

If you make the solid model I can have them machined

I still want a Cosworth intake thought !!!!!!!

[PowerDubs]

The only people I know that have the actual specs are these people-

http://www.actech.de/assets/ca...l.pdf

And trust me, I tried talking to them a long time ago and they aren't sharing due to 'legal contracts'.

I emailed them again a few minutes ago to see if maybe I get someone more sympathetic to the cause.

[newcreation]

Wow are manifold chillen in the pick but cast instead of plastic

[PowerDubs]

Yea...those are the guys that built the prototype for VW that I had.

I figured why they still have it up on the site.Do you still wish you had that manifold?It would have been really easy to change and mod that manifold

I hate this automotive mantra so much I actually feel pain when its said There will NEVER be a solid pricepoint for any project, and you can always be cheaper than the next guy, but you have to pick and choose and scour the 'net; also, essentially any specific part for a VAG car is more than a Honda or Chevrolet equivalent, so you also have to factor in the base car. Reliability and good quality should also not be together, an SRT4 is very reliable but is a Neon otherwise, I'd prefer to pay for quality up front and make the car more reliable with mods. Can we please bury this one?

[Draxus]

I was speaking parts, not the car.

You can buy a part that is well made and reliable. aka wont light on fire. But it either wont go fast and be cheap, or go fast and be money.

Mind you this was a joke and you just ruined it.

lol
