I have a 2007 mini copper s and I am not sure what I am expecting with the turbo.
I had a 2011 Civic SI before this car, when I hit 6,000 rmp the engine would growl and the exhaust would sing lol.

I am guessing I am not going to get as much of a change with the turbo, maybe it is more linear?

How do I know it is working?

I have not really stepped on it yet, just not the way I drive.

To put it very bluntly, it compresses intake charge air to get more power out of a small dispacement engine.

 

Jeremy Clarkson said it best

"A turbo, exhaust gasses go into the turbocharger and spin it, ..., air goes in,witchcraft happens and you go faster."

 

I heard from a reputable source that it has a bunch of whips attached to it that whip the hamsters into going faster. My sources are legit.

 

 

your source is correct. i recently did a swap from hamsters to gerbils...quite the difference.

 

That's the beauty of the twin scroll turbo....you won't feel a surge. Less or nonexistent turbo lag. You'll know if it's not working.

 

I heard the N18 uses gerbils

 

If you "have not really stepped on it yet" you won't know it's working. And if it's "just not the way" you drive, you never will.

 

I've thought about swapping for guinea pigs, but I'm worried the extra torque might damage the frame.






On a more serious note, a turbo is an air compressor strapped to your engine. It's powered by the exhaust gasses exiting the engine which spin an impeller which forces more air into your engine further compressing the gasses beyond what would normally occur in an engine. This creates a more violent and thus powerful explosion when the air and fuel mixture is ignited and thus you get more power than you would have without it.
VTEC on the other hand has to do with cam timing and profile, this is why the engine sounds different when it engages.

 

Well, there's your problem. Proceed to the nearest highway on-ramp and bury your right foot in the gas pedal. Warning: This is highly addictive.

The main difference between the Turbocharged Cooper S and the naturally aspirated (non-turbo) Civic Si that you will notice is, as opposed to having to wind the engine out to eleventy to get torque, the Cooper will serve it up on a platter around 2,000 RPM. So you don't need to downshift as much. Have you noticed you can overtake on the highway without downshifting? Thank your turbo.

 

Can someone delete this thread? Stupidest thing I have ever heard!

First of all, u bought a civic?!? Why, the car sucks ***!

Second, put a damn intake on it or a hks bov if u wanna hear the stupid turbo!

Third, how does positrack on a plymouth work? It just does!

 

Cool story bro.

 

Meh it is a waste of a thread.

 

Does it have a sequel?

 

Lol

 

Also, the turbo really doesn't kick in until after 2k rpm. Yes, its spooling below that. Like someone else above pointed out before the thread was disturbed by unnamed menace, you do have to romp on it to feel it. Also, there's the overboost function above 5200 or so RPM's that really gives a kick (not the same thing as the sport button). Basically if you aren't noticing a difference between your Civic and you Cooper S, then you aren't driving the MINI hard enough to really feel it. If you drove a non-S Cooper then you would easily feel the difference in acceleration.

 

That was the hamster. Growling up to 6k RPM, then finally hitting the (meager) power band, and singing briefly before falling flat on his face.

Biggest difference is TORQUE, and gobs of it compared to the agricultural Civic engine, and it comes on MUCH lower in the RPM range. Drive 'em both back-to-back and you'll know instantly what I mean.

 

No turbo = uhh-huhh. .. turbo = oh yeah!

 

I have had a Plymouth and I know for a fact... that Plymouths do not work!

 

I was more wondering what I should be expecting.

The Civic SI had a definite change at 6,000 rpm.

The Mini Cooper S is defiantly more linear.

I have stomped on it a couple times now that I have had it checked by a mechanic and had an oil catch installed yesterday.

It is very different, and I am enjoying the hell out out it.

My biggest problem is I have a Harley sitting in the garage that I take whenever I can and it is still sitting there cause I wanted to drive the Mini to work.

I also found that I can really enjoy the sport mode on the back roads on the way to work!!!

Some of the threads here scared the you know what out of me so I was a bit hesitant to push the car, but I am getting more comfortable with just driving it and enjoying the awesome experience.

 

Buy the way I drove a Mini Clubman non-s about a month ago.

Compared to the Cooper s it was a dog!!!

 

The over boost function is available from 1600RPM through to 5000RPM, it is only activated when the throttle is snapped opened quickly to full throttle position, supplying an additional 20NM (15 FT LBS) of torque and an additional boost increase of 150 Mbar (2.17 PSI) these additional increases have a maximum operating time of approximately 12 seconds, with any single activated operation from the throttle.
