It isn't at all. Feels like it should have that power all day long. Whilst the M has bigger tyres, it weighs 33% more than an S meaning traction per weight will be less.

Is that true? I dont pretend to understand but would expect the BM to have more traction not less. Its one of the reasons i opted for the BM rather than SC the S (i looked into that some time ago)

I guess the torque is a lot different as its around 400Nm from 3k rpm and pretty flat to 7k

Following from a chat in the pub with mates, the more I think about it, I'd rather save for a car with a decent engine, like a Z4M or a Boxster S. I miss the noise of a decent car (had a M3 and BMW 550i, 4.8 V8 before the S2000), so sure a supercharged S would give me the outright performance, but it still sounds like a 4 cyl a the end of the day, idles just like my mum's Focus and only sounds good inside the VTEC zones, it just doesn't have the drama or the powerful noise of a big engine.

So SC'd MX5 idea is binned Supercharged Z4M, now you're talking

FI does work extraordinarily well with the S2000. Especially a Rotrex, which fixes the torque hole very nicely indeed.

The behaviour will change under dynamic and especially in wet conditions (which is why Mikey fitted TC) but yes, if you desire faster, it's good.

Not knocking the MX-5 (and remember, its Duratec was designed by Mazda & not Ford, thankfully!) but it is a rung lower in price & therefore design dynamics.

But if you're lured by the multi-cyilinder thing, get one before they go out of fashion. It seems as if BMW is emulating EMW and small three-cylinders will replace straight-sixes.

Yes, the BM has more traction than the S, but it needs more traction because it is heavier.

If you are distributing pressure, the S2000 has a 245 width rear tyre and has 625kg over the rear axle. The M3, in order to cope with a mass of 825kg would need to have the equivalent of a 315 rear tyre in order to get the same pressure loading and thus the same grip.

The Westfield is the same. It has a 205 rear tyre and, when the tyres have a bit of heat admittedly, it just grips and goes with zero wheelspin.

I know exactly what you mean, it's such a shame the way the industry it being driven. As you say, everyone will be driving turbocharged 3 cylinder cars in 5 years time, at least a 3 cyl actually sounds quite nice compared to a 4 Joking aside, it's one of the reasons I'm considering saving for a new style Boxster S and a keeper and I've never been a Porsche fan, but they are the only ones who seem to be grasping on to high capacity, naturally aspirated engines and more importantly reducing the weight of their cars and still offering manual gearboxed. Now I'm a massive BMW fan, ///M cars and standard cars, but I don't like the way they're are going. I'd never buy a new Z4 for example, they are more of a GT car than sports car, such a shame.

There are a few Supercharged Z4Ms around. 540bhp is relatively easily achievable.

That being said, the standard 340bhp is plenty and i don't use it that much.

Exactly... and very reliable in standard form. I can see me going this route, plus they are a bit of a bargain now!

Could sell the S2000 and buy a Z4M for less than it would cost me to to buy a MX5 and supercharge or indeed buy a kit for the S2000. That saving could offset the higher running costs. Need to have a think. Or what I really need to do is get the S2000 back on the road and remember how great it is and not want to change it at all. I'm hoping the exhaust mod will make the car sound a bit better (already got a K&N).

That's true. But the market increasingly demands company car-friendly posemobiles, sadly.

I've lost count of whether the Z2 is on or off again; I should have thought that would have been more of a fun drive. But again, that was meant to be four-banger only.

Much as I have a problem with the Porsche thing personally, they are virtually the only company left with a true sports/performance car in the Boxster.
