advertised as "bolt in". my bike is stock. can i just install and get results without tuner? I have rinehart slip-ons and stock A/C

 

Bolt in means no head work required.

You will most defiantly need a tune when you change cams.

 

Zippers is a great company and they sell some outstanding products but the specs on that cam are so far off from everything else I've looked at it's crazy.

It has an extremely mild lobe as well.

To answer the question: YES, you will need a tune. Just an FYI. The SE tuners do not work with aftermarket cams which is why even at your local moco they will put it on the dyno and tune it with something like a TTS tuner.

Just keeping it real.

 

I have an m8 softail and I'm really thinking on this cam. The dyno charts for it are awesome and there was a guy that posted a sound clip on the zippers performance Facebook page. It sounds MEAN,with a really nice lope. I'm going to call them after the new year and ask them how they feel about it in a softail since its a bit different weight than the touring bikes.

 

The dyno sheet you see is virtually the same as what you’d get with the same cam in your bike. The difference in bike weights would only come into play in acceleration rates.
That power improvement would feel great in any bike.

true. I live in the country so most of my riding is back roads so that 468 looks like it's put me in the perfect rpm range!

 

I have the 465..really like the looks of the 468 on the sheet..

 

get up and roll is there, it's still a,lot more than stock even when it drops off so I guess it'd still feel more than stock? My normal riding never takes me over 3700 rpms so I guess I'm right at the drop off point anyways.

 

Agree with the tuner needed, we should not be over camming these engines to put out peak horsepower where we don't ride. Look at specs and call the vendors, of course they will tell you theirs is the best. I think you are heading in the right direction, but as always your exhaust choice is key.

I've got all the aftermarket cam specs in front of me & I don't see a huge difference between most of them, especially the 2 top cams out right now, the CR460 & the RS468. The specs are way different than any of the MOCO cams, but they're dealing with EPA. The stock heads have a poor intake to exhaust flow differential just like the early twincams, that's why the longer duration on the exhaust side. It's hard to argue with the results they posted, it's going to be a big learning curve with the 4valve heads, what worked on the TCs won't work on the M8s. Bob Wood is one of the best on the older motors, but his original 222 for the M8 was a flop, his 22XX is much better, learning curve, the best may be yet to come
