How is your Air Intake Attached ?

The Standard Roadster 100 Air Filter Box is located on the Nearside of the engine.

The Orange Air Filter can be seen in this partially opened Filter Box.

The Standard Roadster 100 Air Filter Extension and Air Intake Tube is located on the offside.

This Intake tube is attached to the Air Filter Intake Nozzle using this large Stainless Steel Clamp.

Note! I put the, now untidy, block of 1/2in Neoprene under the bonnet hinge to stop the Filter Box hitting the hinge.

A view of the Air Filter Intake Nozzle from the near side.

The Air Ducting from the Air Filter Box to the Fuel Injectors is first attached to this control Valve.

The Control Valve is attached to the Air Filter Box using these 4 bolts.

The short curved length of hose is connected to both the Valve and the Fuel Injectors by these two large Jubilee Clips.

I wonder if anyone can help?

While trying to establish the cause of an unusual noise I noticed that the end of the Air Intake was only attached to the New Mulfab Aluminium Radiator Tie Rod using a Long Cable Tie. The Cable Tie was hidden under a strip of Black Duct Tape

This fixing allowed the Flexible Hose to Swing, Move and Slide along the Tie Rod. There is also a home made piece of mesh attached to the open end of the pipe.

Unfortunately, I have no idea how the pipe was fixed when the Original Morgan Radiator was in place or what was on the pen end of the Air Intake Pipe.

Hi Frank.

I still have the original radiator and air intake system although planning to change the Rad as an insurance policy, given the number of failures.

The answer is that there was a standard Morgan factory fitting for the air intake i.e. Nothing.

The open end of the hose was just dangling and facing downwards.

Techniques moved it up above the top of the radiator as I was told that would give the best cool air intake for engine performance.

Pictures attached showing the free end of the pipe pulled out from its current location and in place at the top right hand side of the radiator.

There is nothing holding it in place, its just wedged.

Looks like you have a serious upgrade with your cable tie and duck tape!

Regards, Philip

Hi Frank, photos of our radiator below.

As you can see our air intake is very short with a mesh cone shaped filter fitted on the end (above washer bottle)

I assume that's it?

There are only 3 other hoses on the radiator, top & bottom hoses and a small hose going back to header tank.

Not sure this helps you much?

Good Morning Frank,

As you know I did the conversion of the radiator by myself.

I remember the position of the air intake hose with the original radiator is exactly the same as it is now.

The hose was much more free to get air input in this position because the old radiator was not that height as the new one.

The hose was not fixes there with cable tie ore anything else.

But the air which goes in the hose could not come direct from the front, because of the windshields between grill and radiator.

As you can see at my photo, I also did not fasten the hose after my conversion and it doesn't move.

But I placed it as much right as possible to get nearly 1/4 free input around the outside of the new radiator and something more than 1/4 through the radiator.

Also at the outside I get fresh air because I cut the windshield at the side an bottom (it doesn't fit because of the more laying installation of the new radiator).

I don´t want the aluminium-radiator being touched by the shields!

Now I have a gap between shield and radiator at the bottom about 3- 5 mm and at the top about 10- 15 mm.

I have done some miles since conversion, we talked about last year, and it works in perfect way.

Together with the fluid conversion (Waterless Coolant) now my Fan does rarely switch on and the temperature stays nearly all time at 80 - 90.

I never have seen the "mosscap" at the last photo, so sorry no idea.

Hope I could help you. Wish all of you a happy new year.

Klaus

Hi Frank

Best wishes for the new year.

I can confirm that the air intake hose is exactly the same on Merlin 002.

I have been looking for a way too attempt a cooler air intake position but it's not easy with the front end design.

I thought of extending the hose to try and get a lower cooler intake but don't quite no what the effect would be in the rain.

I have heard of water injection but think I would want more professional guidance.

Let me know if you come up with anything

Alan

Dear Frank,

I can confirm that Phillip, of course, is quite right about the original factory installation of the Air Intake.

Attached is a photograph of my R100 (No. 17) as it came near to completion at the Factory.

It has just left the trim shop and has been pushed out into the yard and the cowl has been removed exposing the end of the Air Intake, clearly resting on the top of the radiator.

There was no fixing; it was just left loose. And that was how it was delivered to the main agents when I collected it
some weeks later.

I thought that there must have been an oversight and that it had not been connected properly: but no - that was it, as
completed by the factory.

All the best,
Robert. (Former owner of R100 No. 017)

Hi Frank

Yes I have the same pipe in the same place loose on top of my new Alloy Radiator.

It is not fixed.

I have been thinking of a mod to make it look better and to keep it in one place , I check to see if it has moved from time to time.

Please let me know how you get on ...

While searching my photos trying to find one of those rubber 'Mosscaps' in use I came across this photo with a very nice front end to the air intake tube ( used on a different model and probably customised by it owner ).

If I can find out its source I will pass on the info.
