Ace, Aceca & Greyhound Forum / Re: Brake pads for disc brake AC Ace

Just thought of another point: the EBC Greenstuff pads do seem more prone to sticking to the disc if the car is not used for a while, don't know if this is peculiar to this compound or whether all non-asbestos pads have this tendency. To avoid rust marks on discs, it's a good idea to roll the car back and forth every week or two while it's laid up. And buy a dehumidifier.

The pads are the same as used in the Triumph TR3A and are pretty easy to source. I use EBC Greenstuff on my Ace 2.6, they give a little more bite than the originals despite being a slightly smaller contact area. EBC also offer another compound called Yellowstuff, can't comment on that as I haven't tried it.

If you can get hold of any, replace the anti-rattle springs at the same time as the pads, as they tend to rust.

Hi all and greetings from NZ.  It has  been a super summer for driving in NZ for the last two months and we have hardly seen any rain - albeit that it looks like this is about to change this weekend.....

A big favour if anyone from anywhere in the world can assist with the request below which is the the last item required to get a Bristol which has been off the road for more than 20 years back on the roads of NZ where it belongs.

I need a set of piston rings for 66mm dia Mahle pistons as fitted to 6 cylinder 2 litre Bristol engines.  Top 2 rings are 2mm wide.  Lower oil rings are 5mm wide, but must be 3 piece or preferably 4 piece for better control of oil consumption.

Any assistance greatly appreciated.  You can also email me on glen@wbb.co.nz

Wishing everyone safe driving for the year ahead

Yes, but don't forget the early and some later European/UK cars not eqipped with the 302 Mustang drivetrain.

Heres a link to another 2 litre for a brave soul.

Again seems a bit too much considering its condition.

Carbureted cars have the single exhaust with the twin outlets on one side, EFI cars have the outlet pipes fed by dual pipes and are on both sides. Simple as that. A single wheelhouse mounted muffler for the carbs, left and right wheelhouse mufflers for the EFI cars.

Ace, Aceca & Greyhound Forum / Re: Ace Bristol Electric Fuel Pump

Ron,

For what it's worth I used to run the engine on both pumps until I noticed it would run just as well whether the SU pump was on or off, but that is on a car run on the road only so Keith or others who also track their cars may provide more complete feedback.

Where do you have the SU pump mounted?
It seems to me that a LP pump should be always mounted anywhere in the engine bay above or close enough to the level of the float chambers. I am not sure how this can be done properly on an A.C. Bristol where the carbs, Solex 32 PBI or Weber (34 ICH?), have their float chambers at about the highest point of the engine bay.

Float chambers are surge tanks which ideally should remain full under all running condition. If they run empty then I would imagine it is not just the flow of the pump that is insufficient but also the delivery pressure, especially when relying on only one electric pump like you do. I could be all wrong but since you clearly stated that your engine started to run wrongly after only replacing the fuel pump then I keep thinking this is the root of the problem in your particular, non-standard set up.

Hi TTM,
Don't know and tricky to establish, I would have to turn engine/pump off as it cut to 4 cylinders and expose the three float chambers, roads too busy round here. My engine has Weber carbs and float levels are as makers settings.
I ditched the old pump when Burlen's seemed confident. Now they are understandably reluctant to be specific on a pump for an engine that didn't have one originally; that's why I tried the forum.
Their high pressure AUA25 has a lower duty (7gph), so not encouraging.
Burlen's data is also confusing, giving the duty of AZX1332 as 15gph in their duty schedule (technical section) and 7gph on the sales page. In a mail they confirmed it as 7gph. It would be interesting to know if Keith's engine runs on the electric pump or if he just uses it as a primer like you.

Thanks for your interest.

I apologize if I offended anyone with this narrative.
