Are you kidding? The S4 is mythical to the Bimmer croud, unless they've owned one.

Default nope. SlvrBulletS4 and TheBollocks have more, I believe. Nonetheless, Hartmann's has more than

the average K04 car out there, so I'd expect it to have more HP.

Default Mark, this is considering the mods - slvbullet is a TRUE exception along with the bullocks

You cant' say that given the mods listed, the hartmann car is pushing those HP numbers.

Default You also said...

"the max anyoen can achieve on the stock block with K04s, even with revised/upgrade cams is 435 crank"

Yet, APR claims 452 on 100 octane on the standard Stage3 kit. So, either you don't know about this, or you don't believe it. Or perhaps you forgot to make a disclaimer about pump gas?

So, for a moment, let's assume 452 on 100 octane for the standard kit. So, now what additional mods does Hartmann have, and will those add up to the additional 58HP they claim?

I'm guessing it's within reason<ul><li><a href="http://www.goapr.com/Audi/products/27tko4_power_figures.html">http://www.goapr.com/Audi/products/27tko4_power_figures.html</a</li></ul>

Default You don't agree it is a bit much?

We've seen most of the plots of the available kits over the last several months, even at speedsport. Most are overzealous claims in the least.

Default Agree, but the Hartmann S4 also has mods that are not present on other cars...

...such as the magnesium intake manifold and HMS Camshafts.

So the difference is more 30hp.

Default Those intake cams and intake mani are STOCK RS4 Parts.

I am one of the few people that have that setup...trust me =)

I also talked to Fabrice about it last week.
