Looking for a roller cam with the same profile as the super 60 Mopar slider cam. Who makes this?:surprise:

Is your cylinder set up to breath?

 

[moparracer 35]

Yes, I did all the work on my bridgeport mill. I am currently running a super 60 slider and would like to go to a roller profile.

 

[detobias]

my cursory Google search showed the 'Taft S-2' is/was a roller version of the S60..
but I didn't see them currently FS anywhere..

and couldn't find ANY cams on the fwdperf website,, dunno if it was me or .

forward motion lists 2 'Turbo' cams but quite a few (also cheaper) N/A cams.

 

[masterjr3333]

I think TAFT is gone.
but both our major sponsers offer cams.
why dont you give them a call and see if they can set you up.

I have never read that anywhere. All sources have told me that The R4+ is the correct S60 specs transferred to a roller profile. There's a big write up on it over on turbo mopar. Chris Wright(Turbos Unleashed) says he has very few left. He was wanting $325 for one last time I talked to him.

DDG yo !

TAFT S2 (re-ground roller) S-60 replacement

DDG- Turbo camshaft & valvetrain

Got one sitting in a box here. Giving it to Kegan Banister soon.

Taft S2 is no where near S60 slider. just look at listing for Taft S3 (Full Race) and it still isn't an S60 replacement.

R5 is closer but slightly reverse engineered favoring the exhaust side.


The R5 and FWD F4 as well as Taft S3 are prob the closest "off the shelf" rollers to an S60 slider.


Simon (turbovanman?) was trying to get a roller version of the S60 made years ago and I thought he had at least a few that got out there, although I can't confirm whether they were actually close or not.


There are other prototype rollers that are still in the testing stages that are beyond the S60 slider, but that's for another day...….

Rob, Chris Wright swears up and down that his R4+ is an exact match of the specs of Simon's cam. Remember the "+" is in there. That's supposed to indicate it's a different cam I guess.

 

[INSATANSSEAT]

Now that I'm thinking about it Rob, I have a P4452899 sitting here.(300/300 cam) I have the high performance rockers, but I don't have the solid adjusters yet. Do you think anything can be done with this cam as far as a turbo application with the right calibration? The St. Louis guys were considering experimenting with it in our Charger drag car.

Where did you get this from? I've never heard it myself, but if it's true I need to do some checking......

That's a Monster! Biggest possible issue right off the batt is the overlap. Would have to run some #'s, but you'd need a monster ported head with a properly designed/built header for sure!

Cam specs;

S60 slider; 112 LSA, Dur [email protected], .499 valve lift


F4 roller; 115.125 LSA, Dur 236/220.5 @ .050, .478/.468 valve lift

R5 roller; 114.625 LSA, Dur 227/219 @ .050, .490/.501 valve lift

R4+ roller; 112 LSA, Dur 217/216.5 @ .050, .495/ .498.75 valve lift

Note; The F4, R5 and R 4+ specs are courtesy of Todd N.(4 L-bodies)

So on paper, the TU R4+ Looks like a roller replacement for the S60 slider, albeit with slightly less duration. Having said that, I don't Know it has less duration because the S60 slider specs were taken from Mopar catalog which also stated 260/260 duration (@ .006 I'm guessing)

The R4+ @ .006 is 263.6/ 268 so who knows, could be nuts on...…...

 

[INSATANSSEAT]

I love that, because I usually take everything the vendors say with a grain of salt! They want to sell sell sell! But at what cost sometimes?

I was messaging Chris on Facebook when he told me about the R4+ and sent me links to Simon's thread on TM. If I was smart, I should have just compared the cam specs myself. I'm never really in a hurry with these builds, though. I do need to pick one up before they're gone. He quoted me $325 and said he only had a few left. This was a year ago.

This thread has actually been an eye opener for me! lol

Looking at my initial remarks, I clearly believed there were no roller cams close to the ol S60 slider.


At first I thought it was me thinking the S60 had more duration then it actually did, but on closer inspection, I think it's because of the 112 LSA. That just says "Hotter cam" to me.


Having had the chance to look at this all over again, these cams are all much closer to each other (and the original S60) than I had realized.:nerd2:

 

[INSATANSSEAT]

:surpriseblink blink) That's why I love to chat and brainstorm about this stuff! I have come up with probably four or five new(new to me anyway) concepts for our platform, but never discussed them or wrote them down, and between the chemicals I have to work with and being generally absent minded, I can't remember one of them. A lot of my being open minded about this stuff stems from reading your story thread that inspires the idea that possibilities are endless.:smile2:

You guys are forgetting one roller camshaft. The old Taft S2+. 114 LSA, .493" lift. That one has 6 more degrees intake duration 223° @.050, and three degrees less duration on the exhaust 213.5° @.050 than the R4+ (roller s-60). Much closer to S-60 specs than the milder S2.

I've put this camshaft in 5) 2.2 engines. Has very good street manners, idles cleanly, and pulls hard to redline. Nice no compromise camshaft.

Really appreciate you saying that, as the only reason I have remained on these forums is to inspire/ pass on info ect.

Funny story;

I look at myself as one of the most open minded people I know.

Many think I Must be completely Closed minded because they Think I'm not listening to their argument.

What they don't seem to get;

1. Real world experience > internet BS


2. If there is any credibility to what they are saying, and they are able to remain engaged in the debate long enough for me to See it, I will be the first to admit I was wrong or out of line debating against it.


I have found very few that remain that open minded...….

Good info Todd N! Now you know why I was asking you if any real specs existed for the original S60 slider


I'm not aware of what the S2 specs are/were? Only that a friend of mine tested the S2 along with several other cams (though he did S2+ as well?) BtB at track with less than stellar results.


Also, while it's much closer to the S60 profile vs S2, looking at the specs you posted, wouldn't you say the R4+ would still be the Hotter cam and closer to the real S60 based on 112 LSA?


This was a big part of my recent "eyes being opened". Knowing what I know now, and looking back to 92-93? when the S60 was developed, they ground that aggressive of a cam to run in a stock exhaust manifold environment.


So anyone with a sufficient amount of cam knowledge, Must have been able to see how much More cam these mtrs could run with modification, even back then!


Looking at all the roller specs, you can see how developers "chickened out" or maybe just decided they needed to grind a cam that was going to make people happy and no issues, as most are ground 114-116 LSA. Like your S2+ @ 114, making it a milder version, albeit better idle quality and over all drivability.


I'm running one of the biggest "off the shelf" roller cams out there and one of my first comments to FWD Performance was "This is not a race only cam, has decent idle and good street manners," and felt that the "race only" label put on it might be scaring ppl away and hurting sales lol


Now, tighten the LSA on the F4 to 112 and things are going to change dramatically...…..

Not all vendors are sell sell sell!! TU has always given me the straight scoop with accurate info. They talked me out of upgrades that I didn't need and saved me BIG $$$.

From what I heard Simon provided a sample S60 roller cam and Chris had a handful of them reproduced as the R4+. Not sure if he has any left.
