Looking for any info possible on this cam. Have you used it? What is it's Base circle size? Rpm range, Dyno sheets and any characteristics of it's profile..How tough is it on valve trains? How does it hit down low, Midrange and top end? I'm sure I can figure it out once a dyno sheet is posted. I just don't know of anyone that's ever used it.... I'm hoping the ramp of this cam is a little less then that of a Woods W8. As for what it's going in, it'll be my 96" Evo at 10.7:1... If you do have a Dyno sheet PLEASE list every part of your build and gearing... Thanx, hope I find what I'm looking for..

It's specs are
26/46-47/25,
252 Dur. Intake and exhaust
101* LSA
.219"/.203" lift@TDC

Yes, I put the same post in the Mechanical section. I'm exploring all avenues... Thanx....

 

You should get 3 more out of a 626V2 instead of the small one your listing

Those Redshifts are about as hard on a valve train as a Woods, they are the old school square lobe but known to put down some power, not to many people know about them.

 

I put Redshifts in an 88" Sportster back a few years ago. 630 intake, 585 exhaust, really early intake close made that bike a stump puller. What I thought was neat was Zippers actually ground down my OEM cams and added the lobes to make the 630/585 cam set.

 

I had a feeling that they would be like the Woods line. With the lift at tdc of .219"/.203 one would think it would ramp very quickly compared to the W8. But with the longer duration and by what I read about this one cam that the base circle of the cam is bigger (but don't know actual size, didn't list it), one would think that the ramp angle would be decreased which in turn should round the corners of that square lobe and make it a little more valve train friendly... I have a call into RedSHift to get that info but no one has called me back yet...

 

Thought about putting a Red Shift in the big cube but started thinking about quick ramps and a faster ratio rocker arms, decided on the less aggressive S&S 650. I've followed those Red Shifts for a while but just not much real world riding on them except they produce real good numbers.

 

If I was to use this cam on the drag strip only, do you think it would out perform the W8...?

 

Been doing some research on the Redshifts, many discussions on the 647 but nothing on the 576. On another forum I rarely posted in has some heavy hitter engine engine guys, they are Redshift guys over a Woods. The 647 was being spoken as a top performance cam with quiet valve train characteristics so your theory with longer duration has less shock with the Redshift could be true.

Found 3 or 4 dyno runs with a 647 on a 120" and the Redshift had the highest tq/hp, still has to have matched components but looks like 576 and W8 are close with a couple of different numbers, did see the duration longer with the Redshift but lower lift.

You triggered something again, after reading all of the info on Redshifts and knowing S&S 640 is soft at my compression, the Redshift numbers on a 647 is like peanut butter and jelly for my engine setup. Thank you for probaly costing me money

 

You know, if there's anything I can do to help I will..... However I think the shoe is on the other for now.. 3 more ponies.... Spending your money is easy.. lol......

 

I can see that can in a big inch motor. With 264*of duration and only. 211" @tdc I'm sure it would perform very well but I'm thinking at least 11.0-11.5 on the comp.... Did any of those guys talk about base circle size..?
