How much horsepower does cams add and when would they be available for the 2000+ models?

That's a bit like asking "What's the best lens for my camera." Basically, you want to select the one that is the best compromise for your needs.

That said, the JWT S3 cams rock. They put out great power at probably the the lowest priced cam ground from billets (do NOT buy reground cams - you're looking for trouble there). They make good power low and really extend the power band higher. They start running out of breath near the redline, but not too badly.

The JWT C series cams are totally awesome, but they tend to give up low end power for high end power. They are designed more for the person whose engine spends most of its time at or near redline, such as on the race track. They can be used on the street, but low end power is compromised to make greater gains up top. They pull hard to the redline and don't run out of breath. They also require the installation of JWTs valve springs and titanium retainers. This almost doubles the price of the package compared with the S3 cams.

At the moment there is no good choice for cams for a roller rocker engine. But, JWT is working on them. They are close, but have elected to continue development. Preliminary tests are quite promising and they will probably be well worth waiting for.

JUN makes some very excellent cams as well, but be prepared to spend twice as much.

hey george,
so it sounds like the s3 cams still work within the same rev range...and will not bring the redline further up... or extends the power band beyond 7000rpm..
is this right?
do you know much about the S4 cams?

I think your assessment is pretty accurate from what I remember. with the S3s you will get quite a bit more power over stock cams at high rpm, but the power begins to fall off around 7000 rpm IIRC.

The S4 cams I believe sacrifice some low end for additional high end power. IIRC it's not significant. For a daily driver, the S3s are probably the best bet.

Now, that said, you cannot use them on your rolle rocker engine. You'll have to wait for the new JWT roller cams. My understanding is they will be rather equivilent to the S3 cams.
