What seats is the SV  tonneau for please?

Paintnuts.

They will take your order and money but they don't have it. Took 8 weeks to get my money back.

DerekH

I was using a Fluke 187

Bit OTT for car electricals

DerekH

Larger electrical surface area in contacts with the coolant?

still not enough to worry about. Interesting though. 
 

DerekH

I connected the positive lead of the meter to the radiator itself so there is a larger and normal surface area in contact. 
 

I think the drawback of grounding the radiator is if you get a sensor fail it could then eat away the radiator. 
I had bought earth straps to bond mine and the decide not too after measuring the voltages. 
 

DerekH

I just measured mine with blue IAHT at -25mV.  Not enough to worry about.

a few hundred mV would be different. 
 

DerekH

Based on the advice from Radtec I changed to old fashioned blue coolant last year.  No issues so far on my Sigma.

You do need to change it every two years.

DerekH

I can weld the frame, although my welding kit is in Yorkshire.  I will mend it.

Do Oxted sell those parts directly? I don't see them listed on the Caterham site.

Its just another of those things when you get inside it you see how simple the construction is and how it might have been made better.

Thanks for the reply, I have managed to contact Gary male and purchase his seats.

DerekH

Looking for an SV black leather seat.  Would consider a pair.

The frame and back on mine has broken.

Thanks

The paper filter is from a 2002 Ford Fiesta Fusion Ford Part 1 729 854

Easy when you have it in your hand.

Bosch replacement £9.95 posted from Ebay.

Anyone know the OE part number for the panel air filter for a Sigma with the cold feed air box?

Thanks

DerekH

Wow!  Two 5 hour stints is hardcore.  That will need an early start!

Route will need a lot more waypoints otherwise one wrong slot or road closure will see you onto the auto routes.

I also see it goes through the centre of Reims, so will need Crit'air stickers and to be Euro 4 compliant in 2024 ?

Think we'd be better avoiding the issues this brings with it

DerekH

Hi Roger,

Carol and I would be interested in coming along please.

DerekH

Probably should be re-badged a 360S?

Please PM me if you don't want to say on here but what was the cost?

DerekH

Interesting. I recall reading the bill of materials at the beginning of this thread. So the ECU was changed and then there was some additional new cabling to connect the solenoids and sensors to the new ECU.

It also interesting that NMS have used different/short throttle bodies keeping the air cleaner within the bonnet line unlike the Premier Power 175 upgrade.  I would expect that PP had some involvement as Troy and Stuart work a lot together.

Very nice!

Just one thing, you might need to enlarge the bore of the hole through the connector as diff oil viscosity is a bit higher than hydraulic fluid.

Was a bit of a beast in its day.

DerekH

That’s it. 
 

DerekH

I had a Girling remote brake reservoir fed from the bottom, this then used to drain back into the diff when it cooled.

Axle was a Salisbury 4HA 5 linked in the back of a Lotus Sunbeam rally car.

Scruitineer decided he didn't like it in the car even though it was inside the rear bulkhead with the battery and fuel tank being a hatchback car.

Sorry, I don't have any pictures of that arrangement

DerekH

Simon,

Caterham have this as a 4 year replacement on their service schedule. Brake fluid every two years.

Worth it for peace of mind, a hose failure could be pretty catastrophic. My car will be 4 years old in January so I think I'll replace mine.

Regards

DerekH

I changed mine at 3 years and vacuumed out the old oil. I came out a nice dark blue colour with no bits in it. 

I was able to remove a liter of oil.  Replaced with 800ml of Castrol Transmax BMW LSD oil. Available on Amazon.

It seems to be more slippery dropping the preload by 4 pounds and made the low speed noise much less.

Diff still locks up nicely when required. I only have Sigma to push it along, so far its holding up OK.

Pre-load is still at 40 pounds.

DerekH

My gauge magic board and LED is now fitted calibrated and tested.

My SV tank takes 38 usable litres having emptied and filled it during the calibration process.

Tank got down to halfway on Saturday and took 18 litres to refill.  Gauge at half full is set at 20 litres. Pleased with that.

Started on Sunday with a half tank and ran it down to 12 litres, to flashing orange warning. LED

Got to 10 litres and flashing red LED, then 6 litre warning with the solid red LED. 

Filled with 28 litres, so maybe some more margin but knowing what the gauge is reading is much more helpful than just a vague indication.

Maybe I could have got more fuel in but covering your shoes in petrol is never nice.

Well done again Andrew.

60mm

On a sample of one, mine only does that when the stat opens.

Derek

When I fill my Sigma I run the engine with the cap off and the radiator bleed open.

When the thermostat opens the header tank level drops and the water comes out of the radiator bleed.

Close the bleed, top it up and run it up to temperature.

Done 3000 miles this year after fitting a Radtec with no issues other than it maybe runs a bit cooler by 10 degrees.

The other way of checking you have no air lock is to measure the volume of water/coolant you put in. Capacity is supposed to be 5 litres

I think I got just over 4.5 into mine as you never get the block completely drained.

DerekH

I fitted a Radtec in March, runs a bit cooler but build quality is fantastic.

They also advise blue coolant IAT rather than OAT (red), saying they only see failure with pin holes in those with red.

Radtec will also make you a vertical version if you prefer it. Having the tanks on the side make it stronger for the mounting.

Get your fan size correct and the mounts will be welded to the radiator. The fan mounting brackets are then not required.
