Jun 272's Vs. HKS 280's 55-60whp!
Here's the straight poop. Straight back to back test with these cams. The only thing changed was the fuelling curve to keep the A/F ratio's consistant.
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.
