So i'm getting near the end of my e36 bmw swap project. It's a stock LQ9 with 317 heads. I'm thinking of using the comp cam 54-446-11.

It's 232/234 duration 0.595 int./0.598 exh. Lift.

I think this is a pretty aggressive cam for this application, but I think it will run well and I'm pretty confident i won't have PTV clearance issues.

What does everyone think? Any estimates on power? I'll be running long tubes with 1-3/4" primaries with a full 2.5" dual exhaust. Unfortunately, I'm running an LS1 intake for now. In the future i could see an LS6 upgrade or something else.


Thanks for any advice! -Jordan

 

I really like the bmw swaps and have a bmw myself. I would tone down your selection on the cam because the car is on the heavier side. Look at what seems a very mild cam for your setup. It will end up running better because you have more torque under the entire curve off idle to redline. I noticed you didn't mention any gears. Do you have the m3 differential? The last thing I would be doing is chasing a power number instead if you want to compare numbers look at average power from 2000 to 4000 and then look at average power at your shift points.

 

Other than being a swap, what are your goals for the car?

Just Cruising Around
Road race
Drag race

 

I'd throw at least 11:1 CR at that for it to drive well and aim more for 11.5:1. So swapping out heads to ported LS6 would get you there without losing PtV.

The cam is a pretty good cam in terms of making power everywhere and having decent manners, especially in a 6L.

 

Nice sized cam for a LQ9 , but not to big at all.
FYI, the XE-R lobes that cam uses are aggressive, so use some good dual valve springs.

 

Ya I was definetely plan on some good dual springs. In the future I want to switch to some l98 heads (I think that's the right number. Maybe l92? I can't remember ). Would this cam be too tame at that point? I guess I could always sell this one and go bigger at that point.

FYI goals for the car are... Well I'm not really sure lol. I drive a GOLF R daily, so this will just be a toy. Might do an autocross here and there. Maybe I'll hit the drag strip once or twice. Definetely want a really fast sleeper. Not concerned with idle quality or anything. Oh it has a tr6060 behind so I don't have to worry about stall speed or anything.

I'm not sure what gears are in it. I've been told by PO the car has the m3 diff but who knows. I don't think they made anything less than about 3.50 gears.
