Check your sources on this. I had a thread on this a while back and the verdict was....no one has hollow cams out right now. Adam verfified this from Jun and Tomei...

 

jun's all day 272 with the springs and get a reflash oh men you will love the h/p.

 

damn jun cams cost an arm and a leg. does anyone know where else i can get them so i can compare prices? right now i found them for $399 each.

 

That's what I paid.....

 

I would pick Revolver cams over Jun and HKS ... infact the more I have researched the more I have found HKS parts to be mediocre ...

 

Ok so where is the proof aka research???

Do a "search" on "revolver cams" and you find that most of the respected folks on EVOm endorse them ...

 

Jun cams are great if you are all out looking for the Max power output. As far as spec wise, the only difference is more lift - 10.8 with the same duration. However, the Jun cams aren't as aggressive as 11.5mm like the Tomei or Revolvers. I would recommend the Jun 272 if you don't care about the crazy cam roar.

Thanks,

Tom, could you PM me a price quote for JUN 272 cams/JUN Springs/JUN Ti retainers? I am thinking about going with a slightly larger turbo for road racing and thought those might be a good addition. I need to figure out how much I need to save

 

this cam roar.. going to be like cammed V8? * wink wink*

 

The test quoted is flawed, simply because the Revolvers have the same effective duration as the HKS 280s, not the 272s as tested.

There is no test as of the present (not that I've seen) that compares apples to apples.


I'd be cautious about recommending that cam set, simply because it gives a substantially longer effective duration than the HKS 280s, which means one should expect a very, very lopey idle and possible driveability issues. In reality, it may present some real headaches.

 

What would the pro's and con's be to the JUN 272's over the HKS 280's. I have HKS 272's now but will be going a different route when I get my stroker and 35R. Would the driveability issues out weight the power gains?

 

How the car drives has more to do with the tuner than the cams. I have the Jun 272's with a ported head and 1mm over valves and my car drives fine. Never stalls, idles solid at 1k. I don't have any issues with them at all.

 

That's somewhat true, but only to a point. I don't see the lobe centerlines published for the JUN cams, so it's not easy to compare them to another cam set.

Do you have dyno sheets?

 

So you are saying the Revolvers are no better then the HKS 280 cams even though there is considerably more lift? Why is it that all you do is defend your HKS 280s?

To everyone though, you need to be shopping for cams based on what you want out of the car, not what everyone else thinks is a good cam.

If it's power your after then IMHO Revolver is probably making the best cam right now. I will tell you right now though they will not provide you your grocerygetter idle you may desire but I have seen them on a bone stock ECU and it still managed to handle the idle pretty well. I agree with enigma19 that it's all about the tune. The Revolvers were designed to work with the stock turbo and as such I am able to hold more boost to redline with no change but the cams. Hopefully soon I will have an opportunity to play around with cam gears on my car to see what will smooth the idle and how it affects the power curves.

As Revolver's name gets out and people start seeing more results you will start to see more and more people going to the Revolver cams. Not to mention thier springs are top notch as designed by a spring guru himself. Revolver is not in the market just to make a buck, they put a lot of thought into design and quality. Fortunately for all of you they are competitively priced with the HKS cams.
I think in time you will start to see Revolver cams in the fastest Evos in the world.
