It looks like you have the more expensive sport back box which being smaller doesnt have the second support shown here on the standard item. To straighten yours up I can only think of putting and additional hanger from the diff to the centre pipe as is used on Vitesse and Heralds...
-
What can we do to get this "swirl" in our inlet manifold/heads then John?
-
Do a compression test, dry and wet if necessary, to see if grinding valves would be a good idea while the head is off...
-
No, no, I meant from the problem you describe I dont think the issue is that the pump is too small. Could it just be that the engine flooded after stalling and thats why it took a while to restart?
-
Yes that is good especially if the head hasnt had any valve work either...
-
They would be Bar where one equals 14.5psi so your readings look pretty good...
-
Wouldnt have thought thats a pump that cant keep up with demand as the symptom is usually cutting out at high speed going up a long hill ie. a sustained high flow is required. If that happens you slow down, the carbs refill and you carry on ok...
-
Ah ok I'll stop worrying about mine then😁
-
What were the symptoms Paul?
-
Has the gearbox been raised as high as possible as well? Sometimes the mounts deteriorate, especially on non OD, and it droops...
-
Only the clamp I posted earlier and now I think about it with the drain holes in the filter box I really cant see the hoses help much either at idle or going along☹️Perhaps the best thing is you can tell people they boost inlet pressure (seem to remember motorcycles had something similar at one stage)...
-
Weren't Solex European or something so might have used metric?
-
Good news on the fitting and I reckon the suppliers need to know👍 The pump is strange (3/16 is brake pipe size) and so to stop the swaging effect it sounds like you might have to solder the olive right on the end...
-
Any ideas why anyone would change the carrier cups position like that Iain? Seems crazy...
-
oh no now its got out we'll have threads disappearing all over the shop!
-
It'll look great if nothing else! Dont forget to have the good drain hole you mentioned earlier in it as this is to allow fuel to run out in case of a carb float valve failure (the overflow exit is in the inlet face of each carb)...
-
Only need a cap to stop coolant from slopping out as you go round corners! Reckon it would mean you could leave your hoses even longer Colin - any cracks you can wrap in sellotape😁
-
I know its a very involved subject and this is Wikipedia's take on it: 'Turbulence in the intake helps to break up fuel droplets, improving the degree of atomization. Better atomization allows for a more complete burn of all the fuel and helps reduce engine knock by enlarging the flame front. To achieve this turbulence it is a common practice to leave the surfaces of the intake and intake ports in the cylinder head rough and unpolished'
-
Yes dont they recommend not polishing inlet manifolds too much but leave a bit of surface roughness to give some turbulance to aid mixing👍
-
Thats the thing with waterless there should be no more hose bangs (or head coolant leaks either) as theres no pressure. For the same reason the rad cap never has to open to vent excess off to the bottle as the engine warms up...
-
As an aside, do you still have the overflow pipe and bottle on your cars? I would have thought them redundant with waterless coolant and should mean that topping up the bottle once in a while is no longer necessary. Of course a down side is that theres no longer a way to see the system is full without removing the rad cap...
-
Think its smooth air into the carb and then some turbulance in the manifold/head to promote the best fuel and air mixing... Also of course the airbox design has more effect the higher the flow rates so for my pootling I dont think its causing a major problem😁
-
Could be worse Mack. Could be a mk1 and then the manifolds have to come off again to do the second torque down😭
-
Looks like theres quite a hefty radiator fan squeezed in there Mick so that will help to keep the air moving under the bonnet when stationary👍
-
Its certainly got the radiator mounts of a Vitesse which I dont think the Heralds had as their rads were mounted further back...
