Cammed FR-S/BRZ? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Chad · 05-17-2013, 05:51 PM

Hey guys, I'm just posting this out of curiosity... Has anyone thought of camming their car? I'm not educated on this topic or anything but I know guys with WRX's and STI's doing it and it makes the car sound ridiculously good.

Again, this is simply out of curiosity and would like some opinions from people who know more about this. What would be the benefits and/or downfalls to doing this?

Here's a few videos that grabbed my interest on this topic:

Thanks.

EDIT: I meant to post this in the general forum (probably would have been more appropriate)

No cams have been released yet. But there in the works.

Still waiting on Tomei and a few others to release some cams...I hope they come soon

The gains would have to be huge for me to have my car sound like that. If i wanted a loopy idle I would have spent $500 on a 5.0.

Downside? Kiss your fuel mileage and low end torque goodbye

They haven't released that info yet.

Why's it sound like that at idle?

In simple terms, with a larger cam prophile, the valves are held open longer to allow more air and fuel in, and exhaust out. During low engine speeds such as idle, there is a point in the combustion cycle that both intake and exhaust valves are held open at the same time, causing the "lumpy" idle. Here is a good read on cams if your bored.

How would that affect mpg?

Its hard to say. It will depend on what type of set up your running. But anyone who goes out of there way to run a built engine with agressive cams, probably isn't too concerned with gas milage.

The FA20 has a good VTC setup. 1 for each cam. We will be able to have pretty aggressive cams for high end and still retain good idle and low end driving.
