anybody get the roller rocker cams yet?

Not here...

Some have over on the B15Sentra.net forum. The owner of the site is registered here as "david". Maybe he can share what the people over there have said about them.

two people have them over there

One guy Eric helped them do the testing. The dyno charts showed a gain of 9hp peak and a max gain of 12hp right at the redline.

Another guy Xsanity had them installed at sr20dev so jwt could create instructions for it. I believe he is going to the upcoming socal dyno day so there should be some new numbers to back up the prototype ones.

That's awesome! What were the other mods?

the roller rocket cam, are they any good for turbo application?

Yup. Idealy you need to dial out some of the cam over lap for the best turbo performance. But they work just fine with turbos.

hey g-sport do you mind telling me where you got those rollerrocker cams. thanks

Well these are "S" series cams. I would rather wait to see if they make a "C" series cam for the RR motors.


The "C" series have been proven to be superior for a turbo application.

Personally I'd stick with the S series on a street car. Of course the 'C' series are better in every way for peak power. I've seen a car with the S4's and if the C2/3's are worse I don't want them. The S4 cams are about as agressive as I'd want on a daily driver, especially a G20. To each their own I guess.

well, the C series cams are good for turbo application, and if this turbo application is used for street driving, isn't this what you both said? LOL =)

I'm not sure exactly what Brian means. I'll agree the C series cams will get better power. But I don't think most of the people on this forum would be happy with them. The idle is very, very lopey and low end power is not be very good. Combine the low end power and the turbo lag it might not be very fun in bumper to bumper traffic.

However turbo with C series cams would rip it up big time power wise. It really depends on your goals and what you're willing to live with. The S3's that I have lost a bit of low/mid torque. More than I'd like but once the revs get past 4000rpm I forget all about it. ;) The C series would probalby be even more on the extremes but aren't as dramatic on the low port motors. Problem with the C series cams is that you NEED to buy JWTs spring set which runs over $500.

I see Brian going balls to the wall all out fire breathing motor here. Truth is the S3 and C cams are both good for turbo. Just depends on how much power you want, what you can afford and what you are willing to live with as far as annoyances.

so for the less hp hunger-typed, the S4 should do the job? Otherwise, depends on my tolerance for low end loss? Hmm....

but it's also depending on where you live as well. for my case, I live out in the boonie and most kms are highway, the problem with loss in the low end shouldn't be of the concern.

Suit yourself. ;) I'll let you have a ride in my car. Keeping in mind JWT only makes S3 RR cams. :p

well, wouldn't it makes sense that they'd make the C series if they can crack the 2000+ ECU?

yeah, I was hoping for a ride in your car last time!!! =) If I am coming down on the 19th April for the Imports convention, we should hook up!

4sure!

Anyone know the technical differences between the "C" and "S" series cams?

If it is what I understood, the C serious would have long duration and high lift? Which gives them better power at high engine speeds but a poor idle and bad emission at low engine speeds? If this is true, I have to agree with Jason, that for street driving I want a cam that is somewhat in the middle of all of these.

J, do you know any differences between the S3 and S4 cams?

More lift and a bit more duration.
