Schrick Cams- 284 degrees

Gentlemen, you do not need to remove the engine to install cams, nor is their any front cover that needs to be removed to complete this procedure. The only cover that exists is easily accessible and that is for the VANOS gear cover bolts (10mm, and easily accessible). The most important part is having the factory BMW tooling to do the job correctly along with all the correct procedures. There are knock off tools now available as of about 1 month ago, however they have variance in them and will have some slight issues when properly timing the engine.

Gentlemen

Man Malek, you use that term loosely on this forum..

How many hrs. would it take Malek? I'm interested in it as well. I'm thinking a set of 4.10 gears along with the cams and a the rest of a FBO M3 with an 8600rpm limit and it could get interesting.

Dave, it takes approximately 12 hours. But the engine most certainly does not need to be pulled by any means. Sure it would make it much easier, but not a deal breaker.

The 284's are a nice set of cams, I have spoken to Schrick about their cam sets for the S65 quite a bit. The 292's are much more aggressive with a good bump in power and ferocity over the 284, but it takes more work and more money, such as upgraded valve springs and Ti retainers.

Might be a dumb question. But is a custom tube required. For these Cams?

The car will run w/out one but it's recommended to tune the car to see the max potential.

[warp10]

Gotcha. So custom done tuning? Or has evolve or ess already have a tune for this?

I'm sure they have something should you wish to reach out to them but IMO the car should be tuned on a dyno and not run a canned tune. Not many people have ventured into doing NA builds as the costs are very high for little gains. I'm sure a well sorted bolt on car would make decent power but again this is kind of limited territory.

[gobuffs]

Does anybody have the part numbers for the install tools? Also if you have the procedure that would be great.

[bigjae1976]

If the S54 is any indicator...cams with a tune can add quite a bit of power. But 12 hours of labor sounds painful or expensive or both.

Still prefer the NA reliability though.

12 hours? Where are you finding this labor recommendation? Removal of the engine wouldn't make the cam installation any easier. Especially factoring in the amount of work required to remove the engine. I take it by vanos gear covers, you mean valve covers? There are no vanos gear covers.

[FogCityM3]

Was just at Dinan asking about this. They gave me the impression they drop right in but still involves a lot of work.

Also, the only covers that need to come off for cam installation are the valve covers, not the front cover. The swap is pretty easy, with a few special tools. I haven't installed this cams specifically, but I have done plenty of BMW cams. I have also disassembled heads from the S65 and it's really quite simple compared to some of the previous BMW engines, such as the S54 or S62.

[FogCityM3]

Think at Bimmerworld said the ECU would not need to be tuned for the 284 cams.

[s85e90]

Interesting they say the car will adjust to the cams but if it were me spending 2,500 I would def have the car tuned to take full advantage of everything.

[V1.47fan]

It looks like a lot of work for lil power gain.

Interesting.

Some guy on a different forum did cams and a tune on an otherwise stock S54 to include the OE manifolds and exhaust. Dyno'd at 317whp and 245tq which on the conservative side would be a 30whp gain from stock (no baseline was run). Kind of surprising since the consensus was that cams were good for less than 20hp. That has been changing in the E46 world.

I'm willing to bet as time goes on and we learn more about the S65 and the DME that cams will become a great mod from a performance and cost standpoint despite the labor costs.

That won't help you today though. And who wants to be the guinea pig?

[Hujan]

People are saying that cams will add power, but won't they just shift the power curve to the right? More high end power and torque at the expense of low end?

Fine everything I have read and my understanding of engine mechanics yes the power band will shift to the right but it will also add some hp and torque! I'm only worried about loosing to much on the bottom end. As we all know the S65 never had a huge amount of torque and HP down there.

[pbonsalb]

Won't know until a few people have tried them. Who wants to step up with $2500 or whatever for the cams and 12 hours of his time or paid labor?

Stay tuned

Here's the "Vanos Covers" people are talking about, and here's the
BMW procedure for changing cams. Vanos Covers are called "timing
covers" in the photo, and must be removed to replace the cams.

[Richbot]

Now I'm curious about something else. Let's say some hypothetical moron decided he should "while he's in there" getting his 4.2l Dinan rebuild installed he should do the cams too? Think the extra displacement would help accentuate the gains? The displacement change is all bore so I would think it would really only help move more air at the topend anyway, right where you need a little more can maybe? Could be a pretty nice setup for a circa-450-460bhp (with supporting mods) but still stock redline and relatively cost effective street NA motor when the time comes to refresh?

Apologies that was uncalled for. Too many rage pills when I posted that. Thanks for not flying off te handle at me too much
