Camshaft question

[meminiau]

Hi all,

When I first got my drivers licence, my mates and I used to get cam regrinds on our cars to get more power out of our hillmans, triumphs, etc. It was a great idea and always worked, and they sounded great too. Nothing like a lumpy cam

I am doing the valve stem seals soon, and was thinking about having some work done on my cams while they are out. I am assuming that it will make a difference, but how will it go with the fact that the car has a computer? Does it matter?

Has anyone done this? If not, why not?

I drive an NG v6.

Cheers,
dean

Your lumpy cams would have had additional duration and overlap, and probably extra lift too. All of this is great for extra power, but generally at the expense of bottom end torque. That sucks when you're crawling offroad.

I'm sure if you get the right regrind you could improve performance without sacrificing bottom end, but I'm not sure what you'd look for.

A mild cam and your computer should be able to cope as it is, but it is possible to "tune" the computer a little - Frank had his done.

Give it a go, but be aware of what you might lose as well as what you might gain.

Cheers,

Scott

Be very careful with any work done to the cams. When I had my engine rebuilt I was told that any work ( mild or heavy) would require an aftermarket computer chip. I took the time to ask lots of Q & A from quite a few different shops and not one advised working the cams unless I was prepared to upgrade the chip.
