i'm looking at cams & wondered if anyone has tried out the revolver cams. Tomei's has the most drivability (260 degrees), HKS has the most options (264/272), but revolver has the highest lift duration (in the 11's). the revolvers also come with everything included around $900 for both. anyone think they can help???

Im waiting on more developements on these as well. I saw a video with sound of them installed about a month ago. Search

 

I think HKS 264's are more driveable than the Tomei's because of the lower lift. Mine idle exactly like stock.

 

one of the guys from www.ktrperformance.com is running them in conjunction with Autotronic, and is yielding good results. He could probablly provide you with a dyno sheet as well. I will get in touch with him and see what he has to say...

 

We are currently testing the cams in a couple different car configurations. So far our tests indicate that the Revolver262/264 camset is a bit on the big side for a stock turbo/manifold car. They still make good power - but the duration is sooo long that the idle suffers.
We are just getting data back from a test car with a stock turbo but with a DnP manifold and the results are pretty fantastic. I'll post graphs as soon as I scan them. Because of the big lift/long duration the factory exhaust manifold becomes a bit of a restriction. We have a couple more sets out waiting on test data from bigger turbo cars (Garrett GT35 etc.) We'll keep you guys posted about the results.
On another note we sell our valvesprings and retainers seperately as well - helpful if you want to fix the "interference" of retainer to seal contact thats happening in almost EVERY car out there with cams installed
Let me know if you have any more questions.

preliminary graphs here:
clicky clicky



still tuning the car.......and yes that was pump gas 19psi tapering to 17psi at redline, so its a nice safe tune.

 

With a stock turbo are these making more power than the HKS?

 

the graph above is with a stock turbo - I have not tried the HKS's on that car but on others they are within 5 WHP on pump gas. Like I said - these are for the big boys who are planning to upgrade the turbo at some point. We are designing a smaller/tamer set for granny's like me

 

seems like hks 264 is the way to go with stock turbo setup

 

Do you have a plot of the car with the stock cam (on the same dyno)? I'd like to see the area in comparison.

 

A customers car came in today with a set of Revolver Cams, springs, and retainers in the trunk. I took a look at them and thought to myself, "these things look familiar". So I carried them over to my bench, and laid them up next to the Web Street Grinds for a 1g that Im trying to sell......................Exactly the same.

It even appears they took the DSM intake cam, redrilled another dowel pin hole, and made another CAS slot, and moved it to the exhaust of an evo, and vice-versa for the other cam. They even have the same HB005 stampings in the castings and the same logo which you cant really make out. There is one single letter in the middle of the cam that is different on the castings.

Im not sure if the grinds themselves are the same or different, but these cams are definatly coming from the same castings. I wont speculate as to knowing anything further though.

Also the spring and retainer kit that came with it, looks almost like a set of stock *** 1g parts. Who knows!

 

OHHH NO!!!! You found out my secret!!!! Seriously though, there are many other companys getting cam blanks from the same place that we do (webcam included) but I can assure you that the grinds are VERY different. Think of camshafts like you would a computer.....there are a couple hardware manufacturers that everyone uses - like Intel or AMD but what matters is the software ( or in the case of a cam - the grind). So yes - we did use DSM blanks that we built a fixture to re-dowel and slot simply because we are a small business and can only commit to small runs of blanks (25-50 sets). I wish I could forge all my own blanks.... maybe one day

no speculation needed - not the same grind (or even close)


see below...

 

Fair enough. Thats the reason I didnt speculate as to them being the exact same. I only said what I would see with the nakid eye. Most people would have assumed it was the same and blurted out a bunch of garbage that they knew nothing about............................................. .................................................. .................................................. .................................................. ................. kinda like the entire DSM Tuners board!!

Good luck in your venture!

There are only a few quality manufacturers of chill-cast iron blanks in the world. The company that supplies our blanks produces camshafts for many manufacturers OEM applications.

Thank you for your comments.

 

complete bull$hit that dyno graph is not entirely correct
