Motorsport thermostat

[shane@mbtech]

If you guys can make this a sticky.

I am running a motorsport thermostat in my CSL and I would recommend you heavy track guys get one thrown in too.

Keeps your oil temps down, ill report by how much on friday.

Be interesting to see how it performs in high ambient temps Shane. Oulton this week won't be greatest test.

We can compare with you guys though, see whats what.

I reckon it will work just as well as an oil cooler will. But we will see.

I used to see 125*c at oulton virtually all year round, I know its a different car, but if it stays down then its :supz:

I say I have it fitted, Im lying, its arriving tomorrow. Fitting it tomorrow along with some nice fresh oil, an intake air temp sensor, seats, harnesses, coil packs. Getting her tip top for the thrashing at Oulton park.

Pity I not got a set of 18" rims here. :banghead:, I have generous stock of nice 18" tyres.

Excellent Shane. really looking forward to tomorrow.:thumbs:

I've got an aftermarket oil cooler fitted. Had it for a couple of years now. Be very interesting to see comparison in same conditions.

It will be good to get a comparison. :thumbs:

I'm VERY interested to hear feedback on this "upgrade".

On my car the oil temps are always ok but if I really really push the car on track the water temp will eventually rise until I drop down my tempo. It's enough to slow for half a lap to get the water temp down. Still very annoying. Really want it solved.

You have an issue if water temp rising. My water temps have never risen on my car above halfway. Ive had 3 CSL's

Start of HG issues

I was thinking the same thing,seem to remember some of Shims old posts on the same issue.

What about oil temps Shane?

[magnust]

- I have stable oil temps IMHO (can't push it over 125 ever)
- Headgasket is new

Any ideas what to check?

As Brett says the thermostat could be sticking.

IMO throw the motorsport one in if you are not daily driving it, in v cold weather and never getting up to temp.

Hi,

If your running the 55 deg stat, then in daily driving
once its opened, if in good order it will stay open
unless you have ambeint air temp of 7 deg and less.

The idea of the Sport Stat, is to open and stay open.

When you had the head Gasket replaced did you
re- surface / skim the head ?

S54 is alloy head and should be re-surfaced everytime
the HG is replaced.

Many do not and get away with it, some are not so lucky.

Get and old thermostat, remove the centre but keep
the outer, prevents water caviataion, and fit.

If you have water temp issues with what is
effectively 'no thermostat' then its Water pump,
Rad or more likely head related.

Regards,

The Gorilla.

Thanks for the replies!!

It was done by an authorized BMW shop under insurance. They had problems finding what was wrong, the motor had a strong ticking noise. After failing to find the source of the noise they removed the head. They then sent it off for finishing since they found a very tiny hairline crack between cyl. 5 and 6. And finally they found a worn down exhaust rocker on cyl 6 - the cause of the ticking of course - so they changed the cam and all rockers. Would I be right in presuming they'd re-surface, being authorized shop probably knowing this is a must do ?

Sounds like something I could take with me and swap to when at the track? Anyone know of any helpful pics on the net so I understand the "remove the centre but keep the outer, prevents water caviataion" better so nothing goes horribly wrong :smt017
