How would a 114 stage 3 107 compare to a stock cvo 114 performance wise??

Was wondering how a stage 3 107 based 114 would compare to a stock cvo 114 in performance and reliability?  Assume both are tuned.  Thanks for your opinions.

Like they say, no replacement for displacement and time will tell how good the heads are at the higher cubes.

But given the same displacement would the shorter stroke 107 based 114 be the equivalent of the longer stroke cvo 114 in areas of performance and reliability...that is the question. Thanks for your reply.

Simulator shows the longer stroke motor better by 5TQ under 3K, then a wash after that. I'm sure bikes are being tuned/tested as we wait- results should be out within a week or two.

Thanks...should be interesting times within the next couple months.

Well, if nothing else, the CVO 114 would have more left in it.

Just saw a dyno sheet for a M8 CVO- 114/90 STD.   Same dyno showed a 107 @ 101/78 STD.

Just for the record my 114 tuned by Bob came in at  HP-137.47  TQ-133.66.
I think that 114 CVO has a few things missing....LOL

I'll bet yours wasn't stock, either

it seems your comparing a EPA stock bike, to a built to spec fun bike.   do some work on the new cvo and I have to think you may be surprised to be perfectly honest.

pentroof heads are going to be interesting to see how that works out.. as most times at least in other applications it is either a tq head or hp head and trying to make hp with the wrong casting does not work out so well.. small gains but nothing like the properly cast head for hp..  complete wrong location of ports and nothing left to port.. Time will tell. best guess is they are tq as the new cams are small in both lift and duration.

Can anyone tell if this has any squish shelf? Pentroof with squish and dual plug should only need ~21° advance, according to the simulator, but i see HDs stock timing table has 34.5° at WOT/5K.

[spook]

So does the group think the 114/90 numbers are realistic for a stock 114 CVO? I thought with the higher compression and displacement of the 114 it would be a greater difference from the stock 107.  Interesting.....

Still wondering how a 107 to 114 stage 3 HD build would compare to a cvo stock 114.  Or am I missing something in the replys?

[rigidthumper]

107-114 stage 3 will make a couple more ponies and a little less tq than the stock 114 CVO engine due to cam/stroke delta. 

[spook]

Thanks. That is what I was wondering.  Appreciate the clarification.

[Bigbluff]

An argument could possibly be made that the shorter stroke 107>114 could be more reliable in the long run than the longer stroke CVO-114 as the peak piston speed, and therefore the acceleration/deceleration loads on the bottom end, would be less.

Locker 55,  That bike sounds like a real interesting ride ya got there, how is it around town?
