slagao te to neko, evo sta treba 2.0T sa K04 iz R golfa da nagura 420 KSjefferson wrote:Ali zato onaj od 375ks moze bez preinaka na motoru uz jos garanciju od 2god?Seawolf wrote:jefferson wrote:...Jedan poznanik ima 2.0TSI u Golfu 6 koji je ozbiljno pojacan, tj. pojacan sa 200ks na 420ks.

Eno motor preko 200,000km (auto se koristi na 402m trkama kao i za svakodnevnu upotrebu)...Ehm, ehm, uz pretpostavku da navedenu najveću snagu od 420 KS razvija pri 6.000 o/min, kao serijski motor, to znači da mu je obrtni moment koji razvija na tom broju obrtaja oko 490 Nm, odnosno da mu je najveći obrtni moment oko 550 Nm.jefferson wrote:...Poenta je, da nista nije radjeno na unutrasnjosti motora, i motor izdrzava tu snagu bez problema...
Za motor radne zapremine od 1.984 ccm, to opet znači da mu srednji efektivni pritisak u cilindru (pri najvećem obrtnom momentu) ima vrijednost od oko 34,8 bara, što je (kao što i sam znaš) ekstremno visoka vrijednost za motor EA888 kojem nisu rađene preinake u dijelovima konstrukcije klipnog mehanizma, a da može odraditi preko 200.000 km.
It’s the same EA888 engine you’ll find in the new Golf R, but here, its 2.0-litre capacity has been blown to smithereens, producing 420bhp at 6,700rpm and with 331lb ft of torque available between 2,400rpm and 6,300rpm. In fact, 221lb ft of that output is available from 1,900rpm.
Audi tells us the specific output of this monster engine is 210bhp per litre, which is more than even the 2001 R18 Le Mans car, and combined with quattro all-wheel-drive, will go from 0-62mph in just 3.7 seconds.
In fact, we’re told each horsepower has to shift just 3.2kg of Audi TT Sport Quattro Concept, what with it weighing in – without the driver – at 1,344kg. Not quite the 1340kg-1340bhp of the Koenigsegg Agera One:1, but heck, this is an Audi TT.
There is Audi’s variable valve timing system, dual camshaft adjustment and a dual injection system (FSI plus MPI). The pistons are aluminium with integrated cooling channels inside, and the crank is made from ultra-high strength forged steel. Y’know, because it’s got 420bhp.
To accommodate the extra grunt, that EA888 cylinder crankcase is made of a high-strength cast alloy, while that turbo is a newly developed unit producing up to 1.8 bar of pressure. As such, it revs to 7,200rpm, running through a three-shaft dual-clutch automatic gearbox.
