Hey all,

I'm going to buy my second Harley in a couple of months.

Here's what I'm looking at. A 2015 Road King with:

1. Screamin' Eagle 103 ci Street Performance Stage 4 (p/n 92500011)
2. Screamin' Eagle Heavy Breather Elite Performance Air Cleaner Kit (p/n 29400173)
3. Screamin' Eagle High-Flow Exhaust System with Nightstick Mufflers (p/n 64800022)

What kind of hp & torque can I expect with the above combination? The Harley website says the "Street Performance kit produces 103 hp and 110 ft-lbs of torque." How much will the pipes & intake add to that?

The list cost of the stage 4 kit is $1,995.95. The intake is $399.95. The pipes are $1,299.95. That brings the total parts cost to (gulp) $3,695.85.

So, two more questions... What would you expect in service (labor) costs to install the above at the dealership?

Assuming you were willing to spend up to $5K to improve performance, would you do something other than the above?

Thanks for the help!

 

We have done a bunch of these types of builds at our dealership. Feel free to call our parts department and ask for Jim, he can give you real numbers for stage 4's put together in many different configurations.

That's it 103/110 or so. So called "Stage 4" kits have the intake and exhaust on the bike during the Dynamometer tuning.

 

That's a lot of $$$$ to still be at 103"...


Spend $2k more and have a 120ST, warranty, & your original motor.

 

I hope you are able to ride this bike after your done!!! Just saying!!! That is more bike then most can handle but you will have bragging rights lol good luck! Be safe lol

 

I would say with those mods you will be around 110hp. As to labor I couldn't tell you especially from a dealer! My builder did it for around $1500, with clutch work.
I did a stage 4 race kit with Rineharts w/race baffles, and SE air cleaner & I'm at 114hp 114tq

 

I assume you are buying a new 2015 RK. Just a suggestion that will save you $. Put the heavy breather on (I prefer the ventilator, gives you more clearance), I believe Harley already puts the se255 cam in, leave the headers alone and put some decent slipons (I've always used Rinehart and have had good luck with them). The only remap you will need will be a stage 2 download from Harley. You should have 90% of he performance for just under $1k. Ride it for a couple of thousand miles and if you still feel the urge, go for a bigger displacement kit.

 

two words. Fuel.Moto.

should be able to do it for about the same price and be at 107" with more HP/TQ

 

107 Kit (heads, pistons, cam) $1299
Jackpot Stainless 2-1-2 Headpipe $479
Jackpot 4.5" pro touring slip on $499
FM Air Cleaner $149
Powervision $499

= $2925
+ labor.

this would be what i would do on a new build for sure. and there are plenty more add ons if you wanna spend more lol.. or use the heavy breather still for looks.

 

Where in TX are you?

You're at $3700 and haven't mentioned a tuner.... The SE crap is over $600.
