I think you mean the opposite. Higher elevation = thinner air = less efficient turbo.

Thanks for answers everyone.

I was puzzled why they don't put Turbo in all cars..
Logically: Smaller engine, better MPG (when you want it) and same HP would be a no brainer
In reality.. it seems that having a flat 6 engine with 218HP is better then a smaller turbo engine with 240HP.

I'll test drive my friends car (mitsubishi lancer ralliart) and see how the turbo feels

He want to race me, in a straight line, he told me that he knows that otherwise he has no chance

Thanks
Sasha

As I always say, anyone(with enough money and/or knowledge) can make any car go fast in a straight line.

I just happen to know a guy who has a 500whp+ Turbo Camry.

Racing your friend's Mitsu is just dumb IMO.

Flavor 987S has a good sample in the picture attached. Post #8

If you drive on long straights track or street a turbo would be perfect for you.

The picture to the right shows a lot of turns. A turbo engine with lag will be left in the dust.

However, there are other advantages/disadvantages to having a turbo. Specially if you want more power. Option are dependant on how much power you want and what you want to spend. Thise 2.0 turbo engines are capable of producing a lot of HP.

I have a 88 951 turbo S. A perf chip and boost controller can gain 40-60hp. I have friends who have more than 500hp. This is from a 2.5

Exsqueeze me! But, my 993 Turbo with +420 HP will dust my 987S with 280 HP...all day....everyday. But, I'm OK with that!

I drive a 1.8T and I have been known to say that I will never be without a car that has a turbo. I love the way it drives on the street, at the track and I absolutley hate the way it falls on its face on very slow auto-x turns low in second gear. But I can live with that because it is so great everywhere else. Of course this motor has been modified but only intake and exhaust; I have not touched the internals. It now has 202,000 miles on it and has been the most realible car I have owned. I have driven other cars to replace it but have not found anything that I like as much...except for the boxster. But even then I have to buy the boxster as a second car. Just love that turbo motor to much.

Lets not forget that many high power NA engines have no guts below 3 or even 4k RPM. If your comparing NA engines with wide torque curves we should compare against turbo engines with wide torque curves. Not all turbo motors have massive huffers than only come alive after 4000rpm!!! (only the fun ones do )

Nope,
turbo actually works better than NA in high altitude:

A turbocharger also helps at high altitudes, where the air is less dense. Normal engines will experience reduced power at high altitudes because for each stroke of the piston, the engine will get a smaller mass of air. A turbocharged engine may also have reduced power, but the reduction will be less dramatic because the thinner air is easier for the turbocharger to pump.

Beat me to it, was about to come in and defend you there. Less atmospheric pressure is no problem with forced induction, you just run more boost. No such option with NA engines......

Also dont forget that density altitude is a figure that constantly changes (even in the one spot) meaning that your NA engine will always be adjusting to the amount of air pressure in the atmosphere and therefore never really be tuned perfectly.

turbos also make massive torque considering their usually small engine displacement. you would need very large displacement on an n/a motor to produce those torque numbers. Turbos tend to be very fast up hill also.

Driving my sister's Audi A4 with the 2.0 turbocharged four, I personally feel more comfortable driving a naturally aspirated engine better. There is pretty much no turbo lag on the A4, but the problem is that there is a very flat torque curve and its actually quite hard to modulate power, it's either off on on. It might be something specific about Audi, but that's been my experience.
