Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: Ns1 cam sound

That's a bad father. You should never teach your kids to point. It's a dead give away.

 

I've got a cat, resonator and two mufflers lol

 

I couldn't rev my car while holding the camera. You just are asking too much.

 

Serious question so since my old cam was so worn the rockers were lose and had play would the new cam making them tight cause me to lose boost in the top end or is that something the ns1 cam does? I am only getting 12-14 psi when I used to get 15-16. Can I open the throttle body and put an air hose to a coupler adapter to pressurize it and listen for leaks?

 

Its not a whole lot different in comparison but see my stock cam had worn down a lot. So my valves weren't opening as much as they should have. Now I have restored the valve lift plus a little as well as a slight increase to duration. The car feels faster. How much? I can't say but I am spinning in 1st now on 70+ degree days whereas before I could only spin 1st if it was like 40 degrees or colder out. I always breathe in outside air +7-10 F unless I have been idling. The engine bay cooks when my bonnet is shut. I really want to do some hood vents. I just can't find ones I like enough to cut up my hood for.

 

How should the dt bypass valve feel? I mean I can get one finger on the butterfly arm and push it open with not a whole lot of effort. It swings back tight fairly strong. Not sure if the springs going or what. I think before it used to really take some effort to get it open. I've had it for about a year. Maybe 20k miles?

 

You're so cool Dave.

 

Before I even post the pictures I will say my rocker arms had no nicks or grooves to the feel. Which is odd with the condition of my cam I removed. Yes there was heat marks but nothing you could feel with your finger nail. I am on a tight budget especially after my fiancé rolled and totaled her car.
