A friend of mine owns a 2004 VW Jetta GLI 1.8T and he claims that 2004 Audi A4 1.8T has less HP than his. Is this true? I think he told me he has 180 hp and A4s 170. Is this true? or he is bull****ting me..?????????

engine.

The transverse engines are a straight shot into the downpipe. Less restriction allows a more aggressive program.

Oh yeah... his GLI will perform much better not because of 10hp but the -400lbs of weight

true.

the GLI whas a different compressor, which gives it a bit more power, hes not bs'ing

not just the GLI. the main factor here is two-fold.

1: engine orientation. the transverse 1.8t in the jetta only supplies power to the front 2 wheels. though this does not influence power as such, the orientation of the motor leads to a poer gain as described next...

2: turbo/exhaust manifold/exhaust orientation. these components are mounted more efficiently for the motor...less restriction in the manifold, a more efficiently mounted turbo (it is similar, but not the same as the longitudinal k03 sport found in the a4) and a shorter exhaust travel path all contribute to that exptra little bit of HP.

the audi tt 180 uses this exact same motr/configiration and of course makes the same power.

rated engine. It was the first 1.8L engine to meet this new emissions level. In order to do it, Audi was forced to calibrate the engine such that the max hp was 170. I've read the technical article that Audi published in SAE. The Jetta's 1.8T was not a ULEV engine, so it was able to be tuned with a bit more power.

So for a more brief answer, yes, the Jetta's 1.8T has 10 more hp from the factory than the A4. But we're nicer to the environment. :-)

The previous engine only produced 150hp as did the B5 A4 until model year 2000 when Audi upped the 1.8t to 170hp. My '02 Jetta was fun but the audi is much nicer.

Thank you guys! I am a wiser man now.. =)
