Oil diverter valve

[shimmy]

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.

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.

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.

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.

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

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.
