: A lot of my being open minded about this stuff stems from reading your story thread that inspires the idea that possibilities are endless.
Really appreciate you saying that, as the only reason I have remained on these forums is to inspire/ pass on info ect.
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...….
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.
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...…..
