AAN Inlet Manifold on 3b

[Doug_RS2]

Just got the water manifold to sort out plus PS pump bracket to do, and numerous other things no doubt.

Yeah - JUST got that to do!!

Water manifold : cut the 35mm tube off and make it come out so it just points down a bit. I had to shave some off my water manifold because when it cam off horizontal it just touched the runner of the IM I'll mark up a picture.

PS bracket : I had to move it forward and up so the metal high pressure hose missed the IM. It is using an AAN PS pump pulley - although this is on the wrong way round becasue the pump needs to be moved forward that much. It needs some of the PS mount to be ground off so the pulley clears that. I used a bar of steel to mount the PS pump - this goes from the pivot bolt of the alternator - the alternator adjust the tension on the belt.
The low pressure hose to the PS pump - I just chopped the orignal and turned it round - I could use the flexi pipe that is there but will probably replace the whole lot with silicon hose.

Because of the postion of the PS bracket - I had to cut the cam cover away - and it is close to the belt - the 3B is different to the ABY so check if it will fit.

I had to replace the water feed to the turbo - the fixed pipe that goes behind the cam belt won't fit. I used scrap braided hose I have lying around.

I am trying to think of the other stuff that needs doing!

Here is the water manifold - the green line is the bit that is close to the runner. Try and get that low - or at least check it before torqueing it all up.

I used a 35mm 90 degree silicon hoses and a 35mm joiner - and cut the original water hose.

LOL..ok then maybe not, ive chopped the water manifold already, i have a spare head so had everything bolted on it today, need to take more off the water manifold yet though, im gonna make some tube for it and weld it so it points down and across under the IM, then just use the original water hose.

3b's use a V belt for the PS pump so no need to swap pulleys.

Looks like im gonna need some 'bling' speedflow adapters then and replace the whole water feed line.

Hello, beautiful work! Have you done any dyno testing before or after this mod? I'd love to see how this manifold stacks up against a 3B and even a stock AAN piece.

thanks!, yes i plan to do a before and after power run, i'll post the results when i have them

Lol, this has just answered my question from the other thread. Roll on the dyno plot

Good welding, i might invest in a TIG welder as they can do anything from Ali,SS,mild steel.

TIG welders have to be both AC and DC to weld aluminium. I think you reverse the polarity to weld Stainless IIRC.

AC/DC welders seem to be about £700 + for a new one.

Maybe not then!!

Is this in yet Martin? or are you too busy lighting up your Toyo tyres on race tracks!

[martinjs]

Err, no. A sheared water manifold bolt put a halt to it getting fitted. Cant be arsed working on cars in the winter so it took a back seat for a while. But dont worry it will be on soon enough.

Nice work Martin!

I am not going to make a definite claim on this, but to a certain degree I'd have thought an inlet with boost pressure inside is less susceptible to flow inequality as pressure acts in all directions, according to physics!

EDIT: reference to flow inequalities, I was reading the first page of this thread!!!

Yes, but the direction of FLOW have influence of pressure distribution in a pipe or IM.
