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.

Ask and you shall recieve

WOW that is extremely hard to belive but not takin your word would be dumb, dyno or test sheet to help out man?

what kind of power gains could u see with gt35r2.0 running 35 psi with those cams?

Probably slightly less, come on, use your imagination a bit hehe.

martin is working on sheets now

Remember how we jumped from 826 -903 on his car

;) this was a big reason for it.

Eric

hellll yeaaa ha nce job guys, should just change your name to Awesome Moto Sports, what i would do

Is just peak power bumped up, or is it all across the powerband?

Scorke

good question.

ha wait, the site says $960 for the set, is that right? cuz HolyS that is high

its an all around better cam. not just peak power

Eric

Sweet, im guessing some of that comes from a more aggressive ramp up and lift, would you guys reccomend springs if we were to go with these bumpsticks?

Scorke

We are adding them right now but we are out of stock at the moment. we have a ton on order but it is japan so its not a very quick process.

we are selling them for $375 a cam and upgraded springs and retainers are highly recomended.

Eric

Hows the do these jun cams idle with the aem Ems? Are they noticeble?

That really depends on the tuner. Martin has gotten them to idle quite well.
