Personally I don't see why BMW would buy them from Schrick when they can just have them made for pennies on the dollar (compared to Schrick's pricing). Unless Schrick is the OEM for *all* of BMW's cams (which is possible I suppose considering they're a fairly large german company)

Not really a whole lot of R&D that would be needed. BMW already has way more details about how the M54 engine flows than anyone else. Their engineers probably knew exactly how the torque curve would shift by just plugging in the numbers.

besides the fact that we've decided who makes them and what cams exist...


OP - don't waste your money, save it for FI. I have a ZHP, the difference is minimal... price is another story

You could not be any more wrong !

Cams dont come with software, not ZHP nor Schrick. Schrick offers different cams with different lift so suit your needs. They offer 264/248 and 272/256 duration.

264/248 will be much more civilized for street application and for reliability purposes . They will gain 20-40rwhp on B30 motor , DEPENDING on other mods and software used.
274/256 are very aggressive and not really suited for the street , not to mention that you need a 8000rpm redline in order to use full potential of the cams. They will only make power in upper rpms.

ZHP cams are 248/248

Sounds like schrick cams are a pretty good sounding investment. What type of modifications would be needed to get the full benefit of the 264 cams?

^Probably a full-on worked head, depending on the aggressiveness of the cam itself. A proper set of headers with appropriate and equal length/diameter would be crucial, then possibly a better intake manifold as well. Add a standalone to properly tune all of this, and you've spent thousands to maybe, maybe reach 250whp.

It's not worth it.

Yeah, well people with a lot more experience do have issues. The real solution is a custom made oil pump from vaio something (a member here).

Uhh... do you have any sources to cite that the cams have anything at all to do with Schrick?

It is possible. Schrick claims some of their customers are "renowned OEMs":

Hell, I wouldn't be surprised if Alpina has Schrick build its cams.

Perhaps I should have said if you don't know exactly what you're doing you shouldn't be messing with them. Happy?

Safety wiring the nut is a perfectly acceptable fix, arguably a must for cars that will be raced.

Safety wiring may help the nut stay attached to the oil pump shaft but ultimately the next thing in line will fail - that being the oil pump shaft.

The ultimate solution to OPN / oil pump failure is 1) to keep revs down (Below 7k is generally safe), 2) install a high quality front damper and 3) retain the stock dual-mass flywheel.

The M54 just can't rev safely in stock form.

Tools for cam timing are very affordable.

Schrick made/designed almost every cam which was/is used in high quality cars. the are still designing formula one cams and back in time they even designed heads and complete engines.

even the best engine in the world, the famous W16 Veyron Engine, is designed and partly manufactured by Schrick!

Even for a Zhp, I'd still say the Schricks are worth it...only if you're doing the install yourself. I have them at my house waiting to be installed and you can definitely tell the difference between the 264 intake cam vs the 248 exhaust cam. The lobes are significantly bigger.
