Oil cooler diverter valve

[adem.csl]

Cool down laps don't count :hahaha:

Lol bearing in mind my hard lap would be your cool down lap lol

[shane@mbtech]

My conclusion also, airflow

Restricted through a dense set of 2 fans and two rads and a load of plastic.fans being the culprit probably as they are both off on track.

Take one off and remove a few grams of gas out of AC system. Should stop pressure rising in AC system if 1 fan is not enough when stationary.

The canted over rads solution works well, during normal temps often have to run a line or two of tape over the front grill to get the temps up.

My water temps are always absolutely spot on, it is only my oil temps that go to the ¾ mark (never above) - however, I have my number plate "quick release" and never run this on either of my cars on track, which improves airflow no end.

Perhaps I am worrying too much and running it to the ¾ mark is not an issue?

[shane@mbtech]

Most have water temp issues mike.

My oil runs at approx 125 on hard sessions.

I'm going to remove the big huge electric fan on mine and wire in place a smaller fan. This should give better airflow through the rads at the front.
The AC system will only need the fan whilst stationary anyhow, I'll just drop a little gas out the system to keep pressure/temp down in AC system.

My non AC car had no issues at spa, whereas shimmy had to lift off. Well that's what he said, maybe that was his excuse for not be able to keep up

The oil temp has always worried me, but they all seem to do this.

I however this time am running a system that will dramatically reduce cylinder temps, ergo lower oil temps :thumbs:

I think the number plate disrupts the airflow and I think that the fact that I never run mine on track is why I have never experienced water temp issues .

Given I also change the oil after every second track day, I think I'll be okay then, but I will wait with interest to see how Adem's / your car performs with the diverter valve / fan removal and then make a decision on whether one of these with an inline thermostat is worth while.

As I mentioned on a previous thread, the US guys rave about removing the bulky OE fan arrangement and replace with SPAL fans, so is this what direction you will be going?

Interstingly (or not) I never had water temp issues and ran a 3/4 size front plate that didn't get in the way of the rad.

Hi,

Quote- ''I've never seen you mention doing any track days with the car and I would have thought such a recognisable car would get photographed a lot.''

Less is more MikeR, but why would anybody
want to Photo some old E46 Shed plodding around
on line, when you have this splendid Blue Oval
''Drifting sideways round nearly ever corner''
makes for far more spectacular pics.

All the S54 Oil Filtre blocks I have ever had apart
have an oil stat fitted that when open would make
60% flow across the dual bridge impossible purely
by its design/function let alone anything else.

Where is this 40% Flow Data and better still who
complied it ?

Regards,

The Gorilla.

Danny,
Your "bat mobile" needs to get on track more often, I'd really love a passenger ride . And as you know, drifting isn't fast, but is fun (but usually gets a black flag and a "ticking off" :blalalala: ).

Have you seen the CSL on You Tube that the Japanese guy owns - it is very similar spec to yours (aero wise etc) and even more stripped out? he's now fitted a Quaife sequential box and it does sub minute laps of Tsukuba:

The flow data was supplied by the technical guy (Gary Gray) at Bimmerworld . He actually stated that they averaged 30-40%.

Yes spal fan.

Running a little injection system too:-D

Would you mind posting up the info once it has all been fitted and tested ?

Of course.

I want to get it fitted and trialled first. :beer:

Hi,

Mr. Lawsy please tell me that your not going
to run a Water / Meth injection system on
the S54.

The S54 cylinedr head for what ever reason is
prone to corrosion pitting which can occur even when
the anti freeze mix weakens and electrolysis occurs as
more evident around the feed holes for the head water jacket,
BMW has stopped coating the Head Gaskets now and with
replacement Head Gaskets, most S54's have been replaced,
you have raw copper now in contact with aluminium.

The Gorilla.

Its not going to be used on a permanent basis, only on track.
Not mapped in, purely as a safety buffer. Used it on other cars with great results, and no issues.

My car will do about 2000-4000 miles per year, and the Meth will only be injected WOT, on track only.

I am willing to try it, you get nowhere without trying. :thumbs:

Have you tried it on the S54 Danny?

Hi Shane,

I have a S54 CSL cylinder Head here
which was taken off an engine where
Water / Meth injection had been run for
around 12-16 months.
[not by me]

I purchased the engine for the bottom end
for another car as it was only 15,000
miles and thought I could keep the complete
CSL head as a spare.

I will take a couple of pics the weekend
and send you them.

I would be very careful as the the combination
of Iron Block, alloy head, and bare copper head
gasket having a water/meth ''spitzer'' injected in it,
as its already a Bavarian Cocktail that does not
mix so well.

Regards,

The Gorilla.
