AAN inlet manifold on 3B

[Dobby84]

i have a AAN with modified AAN intake and v-belt system
i replaced the pas pump and alternator from the old kv engine and made some custom brackets

Did you have to modify the block at all to mount the alternator?

It would be perfect if someone could measure up the brackets required and sell a drawing or even better the brackets to the job, would probably make a bit of money if they did.

[quattro-nick]

no modify required on the block
the reason why i made it like this is to make enough room for a front mount intercooler with a thick core.it's stands just above the crankshaft pulley (i have b2 chassis)
I would like to help you but it's too much work to break down the engine and take notes from the brackets

[Dobby84]

I wouldn't expect you to do that mate! lol

[Dobby84]

Steve,
I just looked through your build thread and have a better understanding of the bracket you have made at the top now, do you think you can take some measurements next time your under the bonnet? May do something similar and see if a jockey wheel can be used to keep the belt in place.

Cheers

ls it me or the alternator moved from one side to the other (where I had my AC) ?? And the PS pump took its place lower on the block?

I'll try and do the same, small front mount IC.

B2 chassis is similar to B3 right?

After all those custom fits, was the rad in need of relocation?

Cheers

I will fit a 3b mani soon over aby one and try to have the pipe going to intake heat isolated .Probably I will use the phenolic spacer on the intake to cut some heat transfer.

I'm going to cut up my 3B manifold and see if that can be used as a reversed option. I also have a phenolic spacer which might help to leave the PAS pump in it's normal location with a shorter V belt.

No probs, it's now off the car. I would suggest waiting for a better option, however a jockey wheel might just fix the belt jumping issues.

[Dobby84]

Will you still be using the modified brackets?
I'll have them off you if not and look at a jockey wheel set up

Yours as soon as I decide to go a different route

on a 2.2 kv engine from a coupe quattro b2 the alternator was on the same side.
I've just created a new support so that the alternator hangs lower on the AAN engine
the crankshaft pulley is also from the old kv engine that i adapted to fit on the AAN crankshaft
the pas pump stands lower on the block with custom support.
yes,B2 chassis is similar to B3
the origional radiator will fit on the same place if you move the throttlebody to the front from the AAN intake
you need also a 3b or aby water manifold but you must lower the radiator connection because otherwise it wont fit with the AAN intake

As its Friday afternoon and the office is quite I have been thinking about the brackets again.

Would making something like this work?



Cant think if the belt would catch on anything at the moment or how I would tension it.

[SteveH]

You have to take into account the PAS pump hoses and the PAS pulley has to be inline with the crank. You will also notice that one of the three 'V' belt grooves in the front pulley is smaller in diameter. From memory this is the PAS pump belt. Not sure is this was done to reduce the pump rotation speed at higher revs.

[Dobby84]

I was thinking of keeping PAS wheel in line with the current crank pulley it uses at the moment, just twist the pump to clear the manifold. In regards to the hoses I was think of getting new one made or use hard lines???

[SteveH]

The OE PAS hoses have restrictors in them. There are a few posts where people mention replacing them with made up hoses and they have experience weird noises. Not an issue if you go for a side exit exhaust

[Dobby84]

Haven't even started thinking about my exhaust yet but thank you for putting that idea into my head. Maybe a screamer pipe would be more sensible!

Thanks for the heads up on the pipes though, I'll look into it. Maybe an extension is possible.
