install is straight forward, just remove the mechanical fan/shroud for access and than remove the oil filter housing and swap out the oem looking thermostat with this valve and put it back together. I believe this part makes the oil temp warm up slower which isn't a problem in the summer but it might be an issue for cold winter driving

Getting the OEM thermostat out is pretty easy. There was a circlip that holds everything in place. Once the circlip was removed, pull out the thermostat which consisted of a spring, the brass thermostat, and a flange that allowed the circlip to hold everything in place. Then put the diverter valve in the OFH, put the flange on top of the diverter valve and then install the circlip to hold it in place.

What's the reason for doing this Derek?
You suffering high temps?

Had 2nd track day with m3 (first day had a lot otf problems with tyres rubbing wheel arch liners) and after about 10 laps water temp goes really nearly in red, after cool down lap temp back to normal. I have bought a motorsport thermostat and fan as well as oil diverter valve. Car was going well just under 2 secs of best csl lap, still getting used to it.

You must get quicker as do not have to think about the value as it is only an M3 :thumbs:

2 secs still a lifetime derek :supz:

Seem to remember a 2 second gap between them when tiff drove them back to back on the Anglesey track.

[billyboysm3]

Yep the magical 2 seconds, doesn't matter about the price tag the standard m3
Simply doesn't cut it when you have driven both on track.

The Csl does it with ease, makes you look good, even with a stripped out m3 it hasn't got it.

I now really appreciate how good the Csl is. F1 teams would pay a fortune to save 2 seconds per lap.

Will do donny and Bedford after Adem and I fit new bits and square set up so same as Csl, then ponder on a 4.1 diff.

[rstoughy]

Dragged the CSL out of the lock up today then took it for a 5hr run around Royal Deeside......God its a great car, having been driving the track M3 around its amazing the feeling the CSL gives back. Remember mine is still running standard suspension etc and yet still its amazing.

Derek,
Having studied the data from KH I'm about 1.5sec a lap slower with the red car (at the moment). Think I just need to learn how to drive a car with an adjustable set up.
Let me know the next outing and I will try and make it along with the car.

let me know when as once my cecil has done another 800 miles it will be ready for some testing again!!

Main difference is csl was 7 mph faster on main straight. Car much the same through twisties on the vbox file. Using the same tyres that I set the time last Aug in csl, they are now past there best. It's just a fun car that I don't need to worry about, I even let Mark drive car on track.

if its a car you dont need to worry aboout you should be 5% closer to the edge and not 2 secs away from a CSL time.

What does it weigh Derek?

Hi car weighs 1485kg with full tank and me. Had to fit bigger exhaust as too noisy should be around 1500kg. This is the first outing with m3 and tyres are past there best. I expect improvement in my times as I get used to car. Car was overheating a bit after 6-10 laps so will get that fixed out before next track day.

[rstoughy]

That's not a bad weight.
The red one is coming in @ 1546kg with 1/2 tank and me with all the safety gear.

so just 50kg heavier, 22bhp less power, but np holes barred!

you'll be within 0.5sec before long for sure.

Replaced thermostat and ready to replace fan. For the oil diverter valve do I need to remove alternator, airbox to access the housing to fit the valve. Just looking for easiest way to fit valve.

[Mark CSL]

Think its just the oil filter housing you need to remove derek
not sure if the intake manifold needs removed

Have a look where it bolts on before you strip it all off

All fitted no need to take off intake manifold. Air filter box required to be removed fan was already off, remove power steering pulley and alternator for access. It's 6 bolts that need to be removed for the OFH removal. Track night tomorrow hopefully it's a bit cooler.

[billyboysm3]

So with this fitted I take it you need to warm up the oil/car before you drive anywhere?

Taken car to work this morning for trackday tonight water temp came up the same this morning sitting between blue mark and first white dot. Oil temp just took a few miles to temp but sitting about 70 degrees. This was on motorway run about 70mph on 50 mile run guages didn't move during the run . Looking hopeful for tonight and forecast dry.

[billyboysm3]

Cool, also taken M3 to work to run her in for next Monday.

[derek]

Car on track last night oil temp was 100 degress and water temp was middle of the gauge. Last time on track temp reached red and oil temp was 125 and car wasnt been driven as hard, so looks like good results with mods to keep temperatures down. Also took 0.5 previous best time in car now with 1.5 secs of csl and car was about 5 mph slower at end of straights than csl.

[billyboysm3]

I think you really need to chuck it in that hairpin!!

[derek]

How many miles is knockhill track?

It 1.3 miles but more than 2/3 is flat out

Track night tonight now 1 sec slower than CSL. m3 still 5 mph slower on straight but no difference on twisties.
