Dimensions of the 20v quad throttle flange?

[DigitalPho3nix]

Hey everyone,

I am after the dimensions of the 4AGE 20v quad throttle flange? I want this so I can make up some adapter plates for putting the quad throttles onto the 16v.

There is something in this for all of you guys... I am willing to make these in my spare time in the near future (in limited amounts) and sell them quite cheaply to anyone who needs a set (ie. far less than any commercially available plate).

A technical drawing would be best, but a picture with some basic dimensions and radiuses will do.

Thanks!

Chris.

You will have issues trying to adapt the entire manifold to the 16v. It is far better to use the individual throttles and make up a manifold for them. The main reason for this is the port angle which the 20v holds and the subsequent fouling which it will normally cause.
That and all the injector bosses are already in the head rather than on the manifold.

Sorry this is what I meant. I intend to mount the ITB's straight onto this adapter and then straight onto the inlet of the engine.

I want to make something like this, except not on an angle.


EDIT: After looking at the T3 design, it is a good idea to have them at that angle as the inlets will be facing upwards rather than horizontal. I can't make this yet as I have no 4th axis on the cnc machine (yet).

I could instead CNC the actual flanges, and get mandrel bends for the middle section?

EDIT AGAIN: It also looks like they have mounted the ITB's upside down as well?

[takai]

Yeah, the original wasnt on an angle, which makes a few things slightly harder, like water piping. Works fine though.
I have the T3 manifold on mine, and is a brilliant piece of machinery, a tight fit but it works.
Having the throttles mounted upside down is pretty essential as otherwise the TPS fouls on the front water outlet, and the throttle actuator fouls on the fuel rail.

It doesnt need to be on an angle though.

[takai]

That is how the engine bay looks.

How it mounts the throttles (note the small clearance between the throttles and the fuel rail.

The manifold

You can see here how close the throttle actuator sits.

Nice and straight



It sits too close to the front water outlet as you can see here, as such the front water outlet has been modded.
The tilt in it resolves this.

The alternator sits very damn close as well, and ive moved it downwards, as seen here:

but if you could knock them out for less than T3, or same, and have similar quality, you'd have the aussie market

[DigitalPho3nix]

This is what I have come up with so far. Took me a 1/2 hour to make this:







I just guessed the dimensions for the moment, and can easily change them all later.

It won't look like that in the end as the tubular stuff in the middle will be encased in a solid bit of material to cut down on machining processes. I might need outsource to get the insides done, as I have no 4th axis in the CNC. We'll see.

{EDIT: Sorry my bad I thought you wanted the flange on the outer side of the TBs. Sorry}

This is for the Blacktop.



This is what they look like when installed

would a photocopy help you out much? i can do one at work (of the gasket) with a ruler next to it and measure holes etc, not the easiest thing to measure up something like this, but i'll give it a go.

are you right for the head side? will you be doing smallport and bigport versions?

PM me as i'm likely to forget, but i would be keen on having one, im losing interest in making one by cutting and shutting a 4AGZE flange with a 20 valce inlet manifold.

also, not wanting to diss your mad CAD skills, but this design will be less prone to breaking than yours (excuse the dodgy photochop)





good points takai, will have to put this into practice if i end up making an adapter after all.

how long are your trumpets? i can;t remember what the "good" length is, need to look at jenvey or something again.

i will be aiming to make the adapter 90mm thick to allow 200mm between the butterfly and back of inlet valve, how thick is the T3 one?

Yeah, thats not the final design by any means. I am still trying to get the shape right, and then I'll beef it up. I have stress testing software so I can simulate the throttles hanging and bouncing on the flange. A photocopy of the dimensions would be fantastic if possible!

At the moment, I am focussing on the smallport version and if everything turns out ok, then I will make a bigport version.

[DigitalPho3nix]

Ok, I think it is finished for now.

Final port revision:

[takai]

Want to make a bigport one for me? Ill be happy to test it for you

If you happen to have the bigport port dimensions, then I can make a model up and we'll see how we go.

[Talasas]

What ended up happening with this? Did you make a smallport one as well?
