Default 103 to T124LC Swap

Blew my 103 earlier this month and after a couple of weeks the ESP paid to replace the entire motor(2012 Road Glide 44k mi). I ordered the S&S T124LC on Friday - now we wait. Planning on going with either TTS Mastertune or the Powervision. Sticking with my Dragula 2into1 and already upgraded the clutch. Any advice from anyone who has done this is much appreciated. I have a Great Indy who is doing all the work and will get the bike Dyno'd once done.

Default S&s 124

Great choice of engine! It is on my wish list for X-mass With the welded crank and timken bearings it is a solid power plant. There is a local speed shop here in western Canada that deals in S&S and they have the first t143 cu in a 2012 streetglide in BC. It produces over 100 ftpds of torque at 1500 rpm and around

160 hp at redline lol

One member offered to me that i could expect to have to get an upgraded belt drive, Baker trans, chain rear drive... probably why that bike in your pic is $50K.
Here's a link to that - Look for Dodger413:

Drive belts have got a lot stronger over the years, which is why H-D has been able to go from the original 1 1/2" belts to 1" today. The only exception are the trikes I understand, which use a special 1 1/8" belt. Obviously the pulley and belt will swap over to a solo if thought necessary. Harley trans have always been pretty tough and I suspect the current ones will be fine, except perhaps for racing. I know a chap who drag raced a tuned 124" Dyna giving over 160HP with the stock trans.
