Today we did some preliminary dyno testing on our 2014 FLHTK. Bike has just over 100 miles and completely showroom stock. Current conditions are upper 80's for temp and current Density Altitude in our dyno cell is 2762 ft.

Here is a pic from our dyno cell:


I did a series of warmup runs and made the first three dyno pulls. Our baseline dyno test landed at 76.40 horsepower & 90.20 torque which I thought is pretty good, actually the best we have seen on any of the factory 103's. HD is claiming a 10% increase in Hp/Tq for the new Twin Cooled engine over previous 103 engines, comparing results of our earlier testing that is nearly right on the number. Here is the dyno chart:

 

Next up for our test was a quick muffler swap. Note the stock mufflers on the new 14 bike are the same as previous models. Slip on muffler applications carry over from previous models.



Also note the factory catalyst head pipe carries over from earlier models as well



We installed a set of Jackpot 4" Dyno Tuned mufflers. We are starting with our most popular muffler, it is a solid performer and our standard baffle is about middle of the road as far as core size, however due to their specific designs they are on the lower side of the dB scale by comparison to other similar mufflers especially on the stock catalyst head pipe.

We did this test back to back to the stock test, in the time it took to change the mufflers. No additional changes were made, simply the muffler swap. We picked up Hp and Tq over the entire curve, in some areas more than 10%. Ended up 79.90 horsepower & 98.98 torque. Here is a comparison dyno chart:





The fact that it responds to a more free flowing muffler is a good sign, we are very interested to see what replacing the catalyst head pipe with our Jackpot 2/1/2 will bring. At this moment we are current working on initial Power Vision functionality and in the meantime will work on getting some maps done for the Fuel Moto Micro EFI Tuner which is already a direct fit for the 2014 bike.

 

Here is some raw data from our testing today:

That's a nice increase with just slip on mufflers . Can't wait to see what you can get out of this motor . Thanks for posting .

 

nice increase! looks like they might have hit It this time!

 

Jamie is there still cat fiber in header or in mufflers now. after reading again I see u stated stock catalyst in head pipe

 

Did a ride on a Street Glide Saturday in Michigan and was impressed with the new high output oil cooled engine, must have a new cam grind, runs much better than the old 103", don't think just a slight bump in compression made that much difference. Rode back from MI today and the saddle is sore.

 

Can't wait to see what removing the cat does.

 

This was buried in his post.

 

Wasn't that the short bus ?
