What power is that, judging from the vid, I would say 390-400.

My standard e92 m3 pulled away from CSL, much quicker than that.

Im not convinced, its not worth the headaches IMO. Been there done that with jap shit.

The loaded CSL is quick yes, but how much is down to SC, and how much is down to chassis, brake, suspension, wheel, tyre upgrades.

Sorry, but as far as I can see the n/a camera car is quicker than the s/c silver m3.

Granted the s/c pulls 2-3 car lengths but a decent GT3 can do that on a CSL on as slow exit corner and is no more than +2-3/10s a lap. Otherwise the camera car is all over him.

Easy worked out Lawsy, just take a well driven E46M3 VLN car and compare with Loaded CSL and the difference will be the supercharger.

Loaded is not stripped out so it's probably heavier than a well stripped out lightened VLN racecar.

Very odd choices of driving lines in some places.... Out on the straight for one.

The Loaded car is fully TUV certified and has front/rear seats, normal windows, a stereo etc.
I am not saying the suspension + brake upgrades are not making a difference, but these are not the only ones responsible for the 7.22m FULL lap in damp conditions.

Hi,

The main problem with S54 S/C is the
heat they generate.

I do not think I have seen a S/C S54 do
more than 3-4 continious laps at full chat without
having to slow down or stop to cool.

Even those with the larger front inter coolers
and water injection still suffer from
massive heat issues.
Whole engine block acts as a massive thermal
store so the only way to dissipate the heat
is to slow or stop, reason being is that the
Intercooler absorbs most the natural air cooling
that a N/A car obtains when all the temps start
maxing out.

Then with the increased heat, comes even more unreliability.


Vanos + SMG + S/Charged + 3 hard laps of the Spa =

''Ticking bomb''.


But-


Vanos + SMG + S/Charged + 3 hard laps of the Ring =

'' 2 spare laps''

I remember Loaded had heat issues in it's earliest years (change of headers was one thing I remember that solved issues). But AFAIK all heat issues were solved. The times I've driven it - which has been on Swedish tracks with far from optimal conditions for keeping everything cool - I haven't noticed any heat issues or gradual loss of power at all.

Agreed

You need a lot more power to pull away once rolling at speed.

30-60 extra BHP doesn't make much difference.

You need an extra 100 BHP to notice a difference at speed.

+1 :whistle:

Im not a fan of Super charging an M3. Spend the money on tyres, suspension & Brakes & learn how to drive imo :whistle:

[AlexGTT]

Modifying N/A cars to forced induction is all OK in the short term. However, expose them to extended trackwork and as Gorilla said, they soon generate heat and stresses the car is not designed to cope with. Not just engine but gearbox's, diff's and all sorts of other things start to go wrong.

Put a S/C CSL/M3 up against a CSL on one or two laps and it'll probably toast the std car. Give it death for 8 or 9 lap sessions all day at Spa in 25 degree ambients and see which car is still out there having fun at the end of the day?

Give me a bog standard drivetrain with stronger brakes, proper tyres, sorted suspension and good geo all day long.:wink:

Ah yeah, and oil cooling..................etc.:wink:
