Bump for great question, I am running currently HKS 264s with a stock turbo. If I switched to JUN 264 cams would I see a power increase? By the way I have basically all the bolt-ons with an Xede.

we have some 264's on the way and once we get some here we have a couple of cars we would like to test them on.

For the gentleman asking if springs and retainers would be necessary on the IX, Yes they would.

If you need a test car, let me know, I will be happy to have Jon drive mine up. I have a few more 'big' track events, where I could get real numbers.

At roughly 40-41psi on a GT42 we made about 55-60whp more with the JUN 272's over the HKS 280's. Idle quality is compromised with the Jun 272's so I will only recommend them for people running a stand-alone or hard core stock ecu guys. You will not a have a fun time getting them to idle with a stock ECU, but they really wont' be a problem on a speed density based engine managment.

We are now carrying the full line of JUN cams and for people who want to run them with a stock ECU I would recommend the 264's over the 272's. Please call the shop and speak with Eric for further info - 847-709-0530.

Does this apply to dsm's... I remember u guys doing the camshaft test back a couple of years ago and hks 272s made more power then the jun stg 3 http://www.automotosports.com/HKS%20...%20Stg%203.JPG http://www.automotosports.com/cam_test.asp

That's a bold statement! I would like to see a controlled back to back test to support your claim.

The dsm cam test is somewhat in valid becasue it was likely the turbo couldn't keep up flow wise. I have been thinking of doing one (similar to the SMIM test) with some of the new high end cams (pro race comps, cranes, and what ever people want to lend for testing).
I read that AMS was running the JUN cams months ago. I figured they switched from them to the new secret. I guess I was wrong.

it is also because JUN has higher lift than the HKS. if you want to make even more power than that, slap on a set of Piper Drag Race 290 cams that have 12.0mm lift. they can only be purchased thru www.dentistmapped.com who is also an authorized MoTeC dealer which would get your car into the 1000hp range easily. good luck guys...
