I was wanting to know how much bigger I can make my stock 103hp with a stage 1. Can I make it a 131

 

If you've got unlimited funds, yes. Your a f'ckin' troll. Cause you've got NO idea WTH you're talking about. Get the FK lost.

 

In case you are not a troll, and just have no idea what you are talking about:
- the 103 motor reference is the cubic inches of displacement, not the HP.
- a stage 1 is air input usually via an open air cleaner, exhaust upgrade, and electronic tune. It has no impact on cubic inch displacement...and if you are lucky might get you a 10% increase in HP & torque...and a cooler and better running motor.
- wtf did your 131 number come from, and what the heck is it supposed to be?

 

The HP is for the high output I have the 103 high output cubic inch motor. The 131 is the biggest I've found so far that I can make my 103. So the 131 is also cubic inches

 

Since we don't know where the 131 number is coming from, we can't say whether that is cubic inches or not. Where did you get that number?

Typical larger displacements from using 103" as the base are 107", 110", 113", 117", 120" and 124" and all but the 107" require removal of the lower unit for case boring, larger cylinders and the 124" will require a longer stroke crank. There are other aftermarket offerings of larger displacement motors and if you are looking for a larger displacement motor, best bet is to purchase a crate motor from S&S or another vendor; S&S is the choice of many that choose to go to big displacement motors.

 

Yes you can bore the cases to accept a 4.250" piston spigot(we do not like bringing those out that far, btw).
But if wanting to step into that larger cube neighborhood, S&S currently manufactures a 143". 150 ft/lbs, 160 hp on a STINGY dyno.
We have 1 on the shelf with the accompaning 70mm t/body, and mounting
hardwares.

Wow man! You are one of the most abrasive people on here. Do you even know what a troll is? The guy asked a simple question and you even answered it.

 

It's a pretty typical response from him ( unfortunately )

 

Personally I thought it was a simple question and of course I didn't know the answer so I asked. I thought this was the place to ask questions that you wanted answers from different people. No I currently don't know all the language and motor talk. I apologize for that. Even though personally I think he can eat me. As for if I can afford it well I guess I can if I paid cash for my 2014 ultra limited. I have a family member who I pay to do all my work and whatever else I want. However I would like to learn and get other people's perspective. The 131 I was looking at is through Revolution performance I haven't looked into s&s. Also thank you for everyone else who was helpful

 

You have nothing to apologize for!

I don't know anything about the 131 or Revolution performance. But, I would talk to FuelMoto and tell them what you want. FuelMoto's customer service is 2nd to none and I know from experience. I bought my 107" kit from them last winter.
