bmw 323ci with stage 2 cams & supersprint
i just fitted a stage 2 schrick cams in my car 272/256 and a supersprint exhaust will let u know how much power i gain after tune anyone else done this mod

Nope. But you might also want a M54B30 intake manifold. I'm very curious to see what you're power curve looks like, I'm betting peak power will be made in the low to mid 6000rpm area and hold till redline, only because the manifold will not keep up with the cams flow.

Lets wait to see how it comes out before making assumptions!

Very true. Those are VERY large cams though, they normally would be making power around redline or even above it.

Yeah, schrick says peak power would be around 7300-7500 if I remember correctly.

does m54b30 manifold bolt straight on or do i need an adapter plate

You need an adapter plate for the throttle body. Turner Motorsports sells one.

how much gain did u get from your install

Is your car a manual or auto ?

Have you upgraded your Diff yet ?

Do you have a "before" dyno?

no i dont have a before dyno unfortunatly but i was told that i will lose a bit of torque down low but will gain 30 to 40 hp

Jumped right in with both feet!!!

I love it!!!

What you are probably going to see is a power curve that keeps climbing right to the fuel cut off.

Enjoy your car. You don't "need" a new diff, or intake manifold...but you might "want" them later on.

BTW, don't let the dyno operator tie onto the rear lower control arms with tie straps. They will bend.

Thanx for that bit of info mate and thanx for ur support I can't wait for tune should be interesting

I'm expecting this. A M54B30 and Shrick Cams with a M52tu intake manifold. Notice the plateau of power because the manifold is restricting flow in the higher rpm range. This car is down about a good 5whp from a stock cam B30 with similar mods and down 15whp from those with cams.

You are the dyno chart king...I wont' argue that. But...I wouldn't put too much weight on an uncorrected dyno. The chart needs to be SAE for it to be "valid" in my opinion.

My SAE numbers were a little lower than my uncorrected numbers and at times, spot on. I don't think we'd see a huge change in power curve with it applied. I will admit though, there is more to this dyno that I lead on, including disabled vanos...

got car back after tune will put up data sheet in the next couple of days but i gt max 157.1 kw at the wheels which means 210 rwhp
