VS Cam and 1.9 Rocker Ratio

[Brett76]

Zoomer recommends either the VS Cam with a TB or a some of the stage 1 package.

Due to past struggles with high installation fees, I'm considering the TB and the Rocker Arms.

The rocker arms are 1.9 but the VS Cam is set for a 1.6 ratio. Will the VS Cam be useless once I get the 1.9 rocker arms? Pretty clueless to internal engine mods, any help is appreciated.

That is going to be some crazy lift.

At the stock ratio, that cam is .504.

At 1.9 that is .598. At the very least your are going to have to modify the heads so that the seals won't get pummeled. I think you start running into that problem at .535 or so. That is assuming you have the valvetrain to support it and that you have sufficient piston to valve clearance.

You may not gain a whole lot with lift that high. At some point you stop seeing a benefit with lift. That depends how much the heads flow.

Basically, I wouldn't advise it unless you really know what you are doing.

FYI if you want to know about the 1.9 ration rockers I posted a thread on this. I hope I paste this right... the link below:

Dont get both, it wont work, you will destroy your engine. The VS cam is the best cam avalible for unported heads.
