Hks 272 9.6Mm Cams

[800KD]

Has anyone ever heard of or used HKS 272 9.6mm IN and EX cams for rb26?? I have had these for a while.

I have searched SAU and google but cant find much info on these cams.

I have heard these cams are the old HKS "STEP 1" cams.

I would like to know if the head needs to be releived for these to be fitted? I was under the impression STEP 1 cams are drop in.

I currently have a pair of the new HKS STEP 1 cams 264 8.8mm IN and EX.

Is it worth changing to the 272's on a mid 600hp T04z equipped Rb26det.

Any info would be much appreciated?

How high is the rev limiter, and when does it make it's bulk torque?

Do you have a dyno plot?

By upgrading your cams you're only going to push your usable power band upwards in the rev range. Do you think you'll need this?

Here's an example

Instead of power at 3000rpm to 8000rpm, maybe up to 4000 to 9000 rpm?

Know what I mean?

This is my current dyno chart. Doesn't show rpm unfortunately.
