Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Would someone really use mineral oil in a serious racing aplication?
I used the Castrol TWS 10W60

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I'm inclined to agree Graham, 10w60 does sound a little thick for the Duratec, I'm sure Matt uses a pretty low viscosity in his monster SBD engine. I'm sure he'll be along at some point.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I was wrong. Matt uses 10w60 Millers oil Graham, so you're spot on there fella.

I'm not suggesting they would . It was just a question .
We use Castrol Edge Sport 10w60 in Dads Fiat 131 Abarth , and it doesn't leak any , burn any , and holds a nice temperature and pressure .

The 10W60 worked perfect for me in the Pinto. Just figured it to bee too thick for these modern engines.

Re: 10W60 - I asked first on the Duratec sub-forum, so its the combined knowledge from here that dictated what I bought. So you're all to share the blame if it goes pop 8-)

I ran 10W40 in my Zetec, and I'd only have 5psi oil pressure at tickover after 15 minutes queing and a flat out sprint round Cadwell, so I'm hoping the Duratec is better protected with the thick stuff.

Wired in the waterproof connectors for the rear wheel speed sensors last night, then placed the rest of the cockpit loom inside the car, and started to try to think of ways of tackling the two ECU connectors that I need to fit on the S80. Its not going to be much fun, sitting cross legged in the cold fiesta for a few hours, crouched over the ECU, cutting, crimping, sleeving, and heatshrinking. Still, its got to be done.

I may pre-populate the two connectors, and then simply join the wires from the connectors to the wires in the loom. That may be easiest given the confined space I have to work in.

Pete McKewan who does all of Racelines engineering development swears by 10W60, he was impressed that I managed to do so much mileage on my 2.3 Duatec on Mobil 1, but convinced me that the 10W60 is much better when he showed me some of the failure cases from Duratec Race engines built elsewhere

Damn you guys! Now you have me second guessing the 5w30 I was recommended.
Oh the decissions, decissions...

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I guess the summers are quite similar to UK summers. But I'll have to gather more info on the Oils with sigma engines. Hopefully Derek at Mountune would let me in on what they used with the S1600 engines.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Different engines too. Sigma lump is the ST170 engine am I right? My brother used 5w40 in his N/A Cossie I believe, and that lasted a long time at high revs.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Sigma is the baby Zetec. All alloy 1600cc. Found in fiestas and Fucus'sand in the new Mondeo with VCT. It was a sigma based engine they used in Fiesta Super 1600 rally cars.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

My Carbon Dash is finished! Hansell Composites are sending it today, so I may get it tomorrow. Even they think it looks fab. They've used a gloss finish on the front panel, and the rest is matt finish.

Finished the goddam wiring last night. No more wires to run inside the car. Now its just a case of crimping 70 or so pins on the ends of the bare wires, and inserting them into the connectors.

I cant emphasise how much I've enjoyed this part of the project, but I'm just so f*cking pleased thats its coming to an end, so i can move on (and get some bl**dy sleep again)

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

lol thats the joys of DIY! At least you know it's right tho . Re the 'screen demisting , do you think there's enough heat off the dash box?
