top end? so i test drove an '00 a4 ws6, mostly for ***** and giggles but if they gave me a steal id take it (which they didnt so not buying that one), and when i got on it, it pulled HARD above 4k-ish rpms. now ive drive a '02 z28 m6 and that did not feel like it had the same top end power??
ws6 had lid and full exhaust (and susp and rims but that would not help the top end)
is this common and the z28 i drove just didnt have the same up top???

i did not/ do not own either. i test drove the a4 yesterday and a buddy of mine let me drive his m6. but the dealer could not contact the previous owner, but i am thinking that it did have headers, as OMGWTFBODY said, and maybe some gears. the exhaust was pretty quiet but it did feel sluggish under 4k compared the the surge that came on after 4k. you guys say it might be dif, i just would have liked to have them contact the previous owner for all mods.
well the 01-02 f-bods got a diff cam, the truck cam from 6.0L, allowed removal of Egr due to overlap, created a little more bottom end torque, and i would assume since it is a smaller cam it affected the top end pull
98-00 cam 198/209 dur .500/.500 lift
01-02 cam 196/207 dur .467/.479 lift
98-00 had longer duration and more lift so more upper end power

well i read somewhere here if you remove the baffels it makes it a true ram air and the air intake temp will be almost exactly what it was outside. and it just so happened this i test drove had an aero force gauge that told me just about anything i wanted to, and the intake temp was damn close to the outside temp. so maybe ram air played a small partt????? maybe not. im not so knowledgable liek all of you, just throwing it out there. like i said, cant contact previous owner so idk what he did besides the obvious.
but thanks for the cam info 02silvaZ. that may have been part.

The first time you drive one is always different. My H/C car was simply amazing the first time I drove it. It was sick for about 1 month. IT was ***** fast for about 2 months. It was quick for 3 months. Now it's just your "average" H/C car.
What pulls "hard" is relative, and ever changing. The faster your car, the harder a car has to pull in order to impress you and put that "knot in your stomach." BTW, an m6 should "feel" like it pulls harder because the shifts are more violent.

Honestly unless the cars had some unknown mods then I would say its all in your head. I mean if the A4 had a shift kit and stall with full exhaust and bolt ons and the m6 was dead stock then maybe but it shouldnt be that noticeable unless the z28 had some unknown issues such as clogged air filter, crappy gas, clogged cats, clogged fuel filter/injector. If it wasnt that much of a difference then it would be due to the full exhaust but other than that it should be too different IMO.

(one example is when in first gear, its an m6, if you stabbed the gas at 15 mph with bad gas, it seemed to struggle in the lower rpm, while now if you stab it at that speed in first it rips the tires loose
