So how does the McLaren feel like?

[Shaunt]

Hi guys.

I'm always hearing how the McLaren is the ultimate road, but why exactly? I know it is fast, but how does it handle, how is the braking for this beauty?

The McLaren is one of strongest cars I've ever driven. The acceleration is absolutely fabulous.

You have to be very careful with the throttle. If you try to press it down too hard at 120mph the car tends to drift with the tail. That's the reason why most of the existing cars already had an accident.

4 years ago we had a big article in our newspaper. The official McLaren F1 press car from BMW had a crash with the BMW CEO. He took the car for a fun trip and wrapped it around a tree. His argument was that the car had too much power in higher speeds.

That's exactly what I said. But I really have to say that the handling and the performance of this car is unique.

Holy crap, this car is pretty damn powerful.

I never that it's 600hp would make the car wild over a 100. Damn, that is what you call power now.

I guess I'll never be able to control a beast like that, hehe.

Roland, do you know why it wasn't made with a twin turbo, or if there are any modified ones out there?

[Gast RolandK]

Easy question:

Why make it with a Turbo when BMW manages it without one?

And BMW is known as not to be a big fan of turbo engines. And they are doing good.

Maybe turbos were an easier way to get power (as easy as it is for BMW to make N.A. engines). I think if BMW entered the business of turbos they'd conquer it just like they did the Nat. Asp. business.

[thepolarfoxqx]

bmw engines are famous for being free-reving, super-responsive, and ultra-efficent. They make more power/liter at lower revs that any one else out there. bar none. By august, I hope with only small bolt-ons, I will have 100hp/l out of my 318 at 6,000rpms. No other car manufactuerer makes engines capable of something like that, especially not that easy.

A turbo would kill the free-revving and the responsiveness. BMW does magic with deep breathing. Right now, they don't need turbos, and I don't forsee them needing them any time in the near future.

[GIR]

I've seen several BMW engines with a aftermarket turbo. They're able to kill just about any engine out there.

BMW has managed without turbo's and will manage without them for a long time. If you look at the techspecs and the dyno printouts of their cars you will know why.

Heck the only car I know that even manages to come close to BMW's efficiency is a Spyker C8 (155hp/l with a max of 620hp at 4100rpm) and that car costs 600k.

BMW is undoubtly the king of car engineers!

[thepolarfoxqx]

yeah, the spyker engine has to rev to nearly 9k to do it though. BMW has specific outputs beyond belief - and only at moderately high revs.

aftermarket turbos on M5s make beasts wil 3 seccond 0-60s, and while faster, they don't have the BMW responsiveness. BMW has stuff like gas direct injection that will keep them cranking on easy breathing for a while.

[colinsmith]

basically it all comes down to is the turbo lag, you can't have a super sports car like this and have any lag in time between throttle push and push at the wheels. At low RPM's you would not get an immediate push at the wheels when you hit the gas, and where the hell is the fun in having to wait for the power. In fact it is damn dangerous, if you need to push through a corner at 150mp/h and there is no power to do it. Your screwed! and it just isn't Gordon Murray or Bimmers style.

[thepolarfoxqx]

i take your point.

a supercharger is better, but for the most sportly driving, a naturally aspirated engine is optimal.

So often people get tempted by easy power gain though.

Hallo Shaunt,

 

schau doch mal hier zum Thema Zubehör für Britische Marken (Anzeige)? Eventuell gibt es dort etwas Passendes.

[imported_felix]

What cars have you driven then roland? Ever driven a zonda?

[LateNightCable]

I think most any decently engineered turbo car displays minimal lag these days. But naturally asperated will always be more flexible.

[kleinefisch]

If you put a turbo on an engine that already has plenty of early power, then it still has that power, but it has more later on. You can also use turbo lag to your advantage. With an engine that has excellent power all around, but boosted power up top, then you can control whether you want to tap into that based on your shifting style. If you a more naturally aspirated feel, with quick response, keep the revs low by shifting up sooner. If you want that kick, hold into the higher rev ranges and shift later. You would certainly have to learn the car very well however.

[thepolarfoxqx]

the thign is, turbos start to loose efficiency enhancing power at very high RPMS, there is a point of diminishing returns, BMW engines don't stand that much to gain from them.

[skyline R-34]

i think that might be too much power to handle but dont get me wrong i love power but it might be too much like i have a gas r/c car and i goes 65mph and i didnt think thats was good but when i took it out for a spin it was uncontrollable(like way too much power to handle) so i went and boght a better one for a beginer.

[wEstSide]

You can say a supercharger will increase power and be responsive, but it will always rob you of about 1k worth of revs and pretty much kill your top end. A twin turbo system is good, but really a big ass single turbo is the best for power. It won't diminish at the top end, and if properly tuned, can have pretty good response, even better than twins sometimes. The optimal setting for most power at all ranges (from what I hear) is a twincharger, which is basically a supercharger + turbocharger system. This system has only been featured on a few cars (MR2 had a kit and Lancia Delta Integrale had this system, try this link for info: http://www.geocities.com/MotorCity/Lane/1231/twincharging.html

If McLaren were to do a twincharger system rather than the twin M3 motors, I don't know how it would've worked out, all I know is it would've been damn cool and earned it an even more legendary status.

Geez first the topic gets brought back to life after 2 years, then it gets brought back to life again after 1 year.

ive seen many a mclaren but never driven one the fastest car ive ever driven is a jag xj220 but my personal opinion is that they have a similar aim to be the fastest and yet they come across as 2 completely different cars the mac is a lm racer for the road whilst the jag is great to drive but fels weighted and heavy and at low speeds feels a bit dozey because of the horrific turbo lag

what i am saying is that the jag is sleeper supercar it comes across at first as a sharp(ish) grand tourer and yet when u well the turbos up you won't believe the speed but then it was the fastest car in the world before the macca f1

[LateNightCable]

Xj220 was the fastest production car with a V6 that is. And one of the fastest in the world by any means, which is really saying something for "just" a V6.

This topic is three years old, really? Gee wiz.

Interesting this about FI and NA engines. BMW makes great engines... but it's just their image to not bring turbos -- and that's it. Look what they do about turbo technology for diesels! Twin turbo - one for low revs, one for high revs - E60 BMW 535d. That engine got more power and torgue than their own current commonrail diesel V8!

Turbo is certainly not a bad thing in modern cars. AUDI makes the best diesels today when talking consumption/power, but also the gasolines. A chipped A3 1.8T 5 valve/cyl makes an average fuelconsumption of 7.3litre /100 gasoline, that's totally ok with 220 hp! Ofcourse it depends how you use the throttle, but the fuelconsumption can get much lower than you are able to with a V6 for example.

The pump diesels (TDI) AUDI have is the best engines you can get.

[zit]

well i have to say turbo chrging is not as good anymore nowadays the turbo wells up slowly and back in the good old days turbo lag was great one minute no power then next minute you are thrown into your seat and its something like that very few cars offer nowadays 8)

[Thunf]

Yes but that's the whole point. People have complained about turbo lag. Turbos nowadays have variable "leaf angle" (directly translated! ) witch makes them very direct. It's very difficult to feel the turbo lag in modern cars with blades that variates and pick up speed allot faster from the exhaust flow.

[LateNightCable]

Modern factory turbo jobs are more linear in their boost delivery, but custom modified one's can provide that lag and then instant kick.

For an example of turbo lag, and then boost kicking in, try the old Bentley Continental. While that car's engine had plenty of muscle without the turbo, many miss the feel of the big single turbo kicking in. Nowadays, the Bentley's are equipped with smaller twin turbos, so the power range is more broad, but the feeling is different.

[zit]

im sorry to see such great values on cars being lost nowadays and people dont apreciate these simple things anymore it may be heralding the end of 'proper' drivers cars with turbo lag
