That is affirmative, especially with the factory (or similarly sized) turbo.

Nice, a 30ft lb jump from tuned 272 HKS cams to the same with gears alone is pretty sweet.

I had disappointing gains from my head being ported, but I was told that the main reason was that essentially I needed a larger turbo as the weak point was now on the exhaust side.

I already have a ferrea valvetrain so I wonder if this is worth it?

Running Vishnu Stage 1+ (272's w/ cam gears) & some add'l things thrown in.

I haven't seen it with the 272s, but I have with the 280s.

yo saying that the revolver cams make that much power over the HKS cams or than by changing the cam gears and having a good timing on them with a good tuned u gain those #'s, oh yeah 1 more thing when i read specks on cams they say they was 262's i might have missed it, do you guys also have 272?

They are talking about other cams not Revolver.

The HKS 272 to Revolver Cams difference is in the first post. No cam gears or anything.

Revolver only makes one cam profile currently.

I hope I get as good as results w/my 280's once I get the EMS tuned....

hey tom , yeah i see now, well gj on not goin Tomei cams O_O, an actually getting this i guess is not that espensive as i comprehended to be since it comes with everything you need springs, retainers, etc + it's like $19 on shipping , hey hows the idle since you said u had ported heads? how much HP on that set up any ways ?

Mate, I actually cancelled my Tomei order a week back on the strength of:
1) Lack of any real info on them
2) Interest in YOUR revolver project

Thanks man. I'm certainly getting the revolvers...

p.s. I'm also getting carbon drive shaft for my evo (and Sti). I'm also going to be selling my kidney soon at this rate.

So all I need for the revolver set is

1. Revolver cams springs/ retainers
2. 4 cam dowel caps (why do you have to replace if you remove this)
3. Schley Products 91400 - Universal Valve Sping Compressor

Lift makes the power, duration only kinda does

Did you notice a difference in the sound?

I might consider this in the future but without the head work, It just depends on the difficulty and price in tools of doing the job. Can't really know how tough it is to do until your actually doing it.

Where do you get the idea cam duration "kinda of makes power." Try reading up on or taking a course in cam design before you type out misinformation.

Hmm...
Maybe he gets it from the fact that there is less duration with the revolvers and more lift and the car makes more power untuned?

More lift can move more air, that theory has been around for quite along time.{thumbsup}

The reason you need 4 dowel pins is because you have to remove 4 to use the tool in #3

Your 100% right.
Tim wanted to make sure that we saw the raw differences between the two cam profiles. The only way to do this was to leave the tune in the ECU the way it was with the HKS cams. The tune was safe and conservative. This way the differences in A/F, idle, drivability, Timing, long term fuel correction etc could be revieled.

I was warned by Tim, that Revolver mentioned the increase in torque down low would be incredibly noticable. Keep in mind also as Tim has stated , his head is HEAVILY ported. Not your usual animal. In his particular case there is a tremendous amount of turbulance. BUT, when the throttle is depressed the torque is absolutely instant.
These are fantastic cams. By far the best I have tested on the EVO 8.
