Cams...

I've been talking back and forth with the guys at Kent cams for some Aveo/Lanos cams that are streetable (no tappet change, not lumpy).

They have been slow to respond, but this is prime season for race build-up so I'd imagine they are quite busy.

Anyway, the general idea is that a custom grind for the Woo would be too expensive, but they don't know if the X16XE cams will be too aggressive for the valvetrain. There is some fear that the Daewoo tappets might not take the concussion from the cam and we might get some nasty float.




Sooooo... They are sending me an X16XE cam to try in my Lanos to see the effects. I have an engine that I'm not using and the research will benefit everyone. I actually have three different cam profiles coming from the mild to pretty gnarly staying on the stock tappets. We'll see what comes of it.

Cams should be here somtime towards the end of February...

those of you planning on going turbo might want to stay away from these in preference of your own custom profile.

Correct me if I'm wrong, or if these profiles will cover it:

My understanding is for any decent amount of boost you'll want a decent amount of valve overlap. Meaning you'll want the intake and exhaust valves open at the same time. This will allow the charged clean air being pushed into the cylinder to help expel the exhaust gases, which will be more than the amount the engine was designed for (due to the excess fuel).

I believe you can also fine tune compression ratios to a greater degree of accuracy by changing cam profile, than by changing the width of the head gasket.

Yeah, turbo guys will be happier with the stock cam or a custom grind... stock will be good to well over 300hp (crank) on high boost...

and what if i want way over 300hp? lmao.

Is that advice viable for all boosting or just turbos'?
