IIRC not even the 280 cams gain any lift over the other 264 or 272. So they really just increase the duration by a couple degrees at 1mm.

The whole design of the HKS cams is to try and gain as much power as possible without having to replace the springs. Unfortunately when you design something with an inherent limitation you end up with a product with limitations. Revolver realized this when they designed thier cams and decided to do it right from the start.

If you look at the domestic market you would never see a relatively low lift cam with a lot of duration. Any cam in the domestic market that makes good power will have higher lift with moderate duration.

 

GSC cams are endorsed by us. We sell both. No installation issues with either make. For some reason it seems the GSC units impress us more on the dyno.

 

timzcat ,

I've been waiting for a "respected individual" in this community to try these out. I think once people realize there is more power in the Revolvers with real tuning, they will catch on. Problem is that many tuners who tried them were confined to the tuning mentality of the HKS cam... you can't do that. It is a different animal compared to what many US tuners are accustomed to.

 

What is real tuning? All cams mentioned seem to do a great job. What about valve trane? I am biased on Ferrea because we know it works. Are you saying revolver cams require "real tuning" due to need of springs and tainers? Cause i am lost on this "real tuning" crap.

 

Since I'll be getting my Tomei Poncams in the next few weeks, do you know how they compare with Revolver?

I'm not challenging you here, just wondering since you mentioned Tomei. The numbers you quoted for the Revolver seems to be similar to the Tomei cams.

Also, are you running the revolver with stock turbo etc? And are you having problems with braking?

 

I think what he means is tuning for cams that will make real power and not tuning for cams that are designed to imporve on stock design with the same limitations.
I have no problem with Ferrea, I am running thier valves. At the price of the Revolver springs and retainers though they can not be beat. There is a lot of design consideration that went into the Revolver springs. They are not simply a replacement piece to allow more lift like other springs on the market.

 

I am currently waiting on the cams to get here. I will have concrete data once I get them in but from the information I have now they will definetly imporve upon the HKS 272s I am running now. They (Tomei) are similar and like I said I was looking at those cams originally. I believe the price on the Revolver Cams is considerably cheaper then the Tomei and JUN cams, IIRC. They are around the same as the HKS so on price alone you get a lot more product for your money.

 

Going back to vendor section lol

 

Does anyone have the WORKS cam?

 

For you guys with Piper, which cams are you running? And how much are they (Price)?

Seems very very expensive last time I looked.

 

HKS is about $50 more than GSC and HKS cams have been realiable for many many years. Why not spend the extra 50 and go with HKS that every tuner uses.

 

+1

I got my cams and intake from him, great deal!

 

HKS is the originator , everybody else is the imitater......go with whats proven for YEARS.
I put nothing but the best on my EVO. Why take a chance saving a buck.

 

At least there are a few people like timzcat and yourself that can speak from actuall theoretical knowledge, rather than bs internet hype.
Tuning a longer a duration cam profile is "respectfully" easy. The revolver, piper, tomie cams are a much different animal like you mention. Lift will play a critical role in throttle response and initial lean spool. It requires a great deal of attention to both fuel and timing. These cams separate real tuners from the cartooners.

 

If you make a statement like that, relating valve spings to tuning and EFI system, then there isn't too much to say about your lack of knowledge on the subject......
What works and work right are two different things.
Zues is a very well respected member on this forum. By coming on here and mocking his post about something you should have a clue about is ignorant.
