100bhp/litre is nothing now, the 1.2TSi at 87.5bhp/litre isn't anything spectacular.

Some Japs have been up at 200bhp/litre standard.

Yep, Civic Type-R's at 9000rpm. Now THAT is what I call stressed!

i think the magic number is 100bhp per litre for a n/a engine... no supercharger or turbo malarchy...

most honda's are upto this spec, but not for much longer i hear vtec is finished :no:

Turbo first produce the torque, it's the charger that does that. Charger from low revs, turbo from mid revs for top end power

Turbo doesnt produce the torque, it's the charger that does that. Charger from low revs, turbo from mid revs for top end power

Ignor first post - iPhone spell correct grrr

Oh, and my tuned track car gets 102.3bhp/tonne from a na engine. Blown engines are different and will comfortably produce more power

Per litre. Head is somewhere else tonight.

I think if your more economy obsessed than drivability/performance obsessed the CR is the one to have. It's very frugal and offers a car the size of a Fabia a really good turn of pace, however knowing what the CR engines are like it's probably not all that fun to drive. The CR's suffer terribly from lack of low end go and soft throttle response, think this has been engineered into them to add to the feeling of refinement i.e they dont tend to torque steer or make passengers feel sick with on-off throttle usage.

The TSi's are smooth, punchy and very keen all the while offering low emissions and good economy. Admittedly they are nothing like as frugal as a CR, particularly if driven hard but a TSI will no doubt be more fun to drive.

I've said it before but comparing my 140 CR Golf GT to my Dad's 1.4 TFSi DSG A3 I will contest that the Audi feel the quicker more sporty car with a much more usable spread of linear power and considerably better throttle response.

Turbo first produce the torque, it's the charger that does that. Charger from low revs, turbo from mid revs for top end power

1.2TSi, 1.4TSi (122), 1.8TSi, 2.0TSi all do not have a supercharger but do have small low inertia turbo's that spin up quickly and still manage to produce maximum torque from only 1500-1750rpm depending on model.

Regardless of which Skoda you drive,engine Or transmission you use it's a SKODA ,just warm in the glow of it's greatness , and bask in the knowledge that you drive the best cars in the world(for what you pay for them!)lol

Had a chat with an older chap today ,asked him about his fuel economy he had a elegance 1.2tsi and he was getting 40 mpg ,I was getting 49 mpgfrom a superb2 1.9tdi105bhp is this all the Tsi are getting shocking

If it was an old person he was probably braking going up hills....

A the myrth of youth,in the not to distant future, you will smell of urine!!!

Ah fair enough, if sequential turbo chargers then yes, the small one spins easily before the big one. Not so much about torque though, it's providing low end power to help eliminate lag

Not two turbo's just the one. One modern turbo on a fairly high (for turbo) compression engine with direct injection.

Turbo technology has really advance in the last 10 years, the first 2.0litre Impreza Turbo had 208bhp and 214lbft but needed 3500rpm to get on boost and maximum torque wasn't produced until 4000rpm. Under 3000rpm it was fairly flat.

Forward 15 years and the 2.0TFSi produces 200PS and 208lbft but the biggest difference is the way the boost and torque is produced,

The engine is on full boost and producing maximum torque at only 1700rpm and it can maintain that level of torque all the way to 5000rpm. 80% of maximum torque is available from 1400-6000rpm.

At the bottom of the range the 1.2TSi produces full torque output from 1550-4100rpm.

The unit in the Fabia VRS need a different approach, to get such high bhp from a small capacity unit they needed to fit a bigger high flowing turbo and lower the compression ratio, this leaves a big torque hole in the bottom end which is why they went for a supercharger to fill the gap.

On the other units a supercharger isn't needed as the smaller turbos are on full chat very early.

Torque and power are not two different things, torque is the turning force the engine is producing and the only measurement that determines how fast a car will accelerate. But it's torque at the wheels that provides this acceleration so overall gearing is the deciding factor.

Power is just torque X rpm (divided by 5250 to give horse power) which gives you an indication of how much the engine will be able to make use of gearing.
