Schrick Cams 284/292

So im wondering what the difference is between the 284 and 292 since i have no clue about cams. Also if I were to get a set installed a supercharger would still be compatible right? I dont see why it wouldnt and what about the gains? 20rwhp possible? would i need to get a tune also?

284 $2599.00

284 and 292 are the duration of the cams - basically how long the cam is open. The longer the duration basically the greater the amount of air the cams can let into the engine.

Longer duration cams will shift your power band to the right - so give you more power at the expense of torque down low. In essence you don't gain any area under the curve generally, but for racing type applications, obviously you want all of your torque at high RPMs to make more power.

Without a doubt changing the camshafts would require retuning to get the most out of them. Personally on a car with variable intake and exhaust camshaft timing, I wouldn't mess with the camshafts unless it was from a very reputable tuner (e.g. Dinan) who had done the extensive R&D and fine tuning (i.e. offering in a "package" with camshafts and appropriate tune) necessary for this type of modification on this type of engine.

what if i added the cams to the mods i currently have:

gintani race muffler
gintani catless x-pipe
gintani crank pulley

would torque still be sacrificed? im guessing powerchip would have no way to tune a car with cams right? are dinan's cams similar?

Dinan doesn't make cams for the E9x bro..

Cams and a SC are only compatible if you have a custom tune for it which is very complicated.

Don't bother.
It will not give you much gains and with the cost of install and tuning, better ways to spend you money.
I had cams on my e46 M3.

Schrick is a reputable German engine components manufacturer. They have been making engine components for years, I'm gonna bet that they make the stock cams for the S65.

Anyone who has been in the VW tuning scene is familiar with Schrick....... they make good parts that make good solid gains, albeit not huge gains. Schrick 264/260 cams for the VW 2.8l 12V VR6 gave a nice bump in low to mid range torque along with a bit of top-end horsepower. Schrick 268 cams for the VW 2.8l 12V VR6 gave a bigger bump in top-end horsepower while maintaining 95% of the torque curve.

I would say that the 284 Cams for the S65 will make some power and will maintain most of the torque in the low-end due to their milder design. The 292 Cams will definitely make more high-end horsepower but may lose a little more low-end than the 284....... I bet with these and the proper valve springs the S65 will spin to 8750 or 9000 RPM

I may look into these since I am interested in keeping my M3 NA.

Even if the gains were like 25whp I still wouldn't pay the money...

Agreed 100%!! Had Cams on my E46 M3 as well. Save your money and put it
towards a Supercharger...
If you do decide to get cams, You HAVE to get new software for sure...

thats a good point considering how much it will be all said and done...paying that much for juss 25whp(if even that) is not worth it....well i just wanted everyones experience and opinions

It is not that much...... an Eisenmann rear section is $2800 and 5 WHP max!!!

I think you can expect about 10+WHP from these...... maybe as much as 20WHP.

The install would be around 6-8 hours on cams though!

VANOS will also have to be adjusted if the cam is aggressive.

Nice, I might get a set of 292 for mine since I'd like to go the N/A route.

Simply installing the camshafts tends to make only a small difference.

From there it all depends on the skill of the tuner and the strategy they use to tune.

Some will only adjust the fuel and timing. Some will go the whole way and alter both the inlet and exhaust vanos profiles.

On the E46 M3 for example, fitting Schrick cams gave a maximum of 5bhp without tuning. It was hardly felt on the road. Many tuners did not know how to adjust the vanos profiles and therefore only every achieved small gains. Some knew how to control the ECU very well and gained anything upto 35hp which made a very significant difference on the road.

As for losing low end torque goes, this can be compensated to some degree by changing the overlap of the cams (by altering vanos profile) at low rpms to retain torque and then increasing the overlap even further at higher rpms to realise more power at high rpm's.

The tuning is the key behind this and it's a task that requires some dedication.

Many people who know their cars notice 10hp from a flash tune and they really notice the increase in power/torque when fitting exhausts like the Akrapovic or RPi.

Once something like these cams are fitted and the tuning is done correctly you'll notice this upgrade. You think this engine gets angry over 5000rpm now? It'll be a completely different story once something like this is done.

The cost is such that most people will go FI but for those who want to stay NA, it's a very good option. Tuning the first one will be interesting!

I was also thinking of the schrick cams, I already have a reflash from EPIC Motorsports. No doubt i will need a new calibration forthe cams. Has anyone installed cams on the E92 M3?

Interested to see the people who have done this before. Has to be since they sell them?

What else can be done to make more power without going stroke/bore. Full 4.0L NA tune?

-Pulley
-Header
-Exhaust
-Intake
-ECU
-Cams

???
