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?

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

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" ).

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
