Mild build on 14 SeBreakout
« on: February 21, 2014, 01:31:33 PM »
Looking for pros and cons for part choices on a mild breakout upgrade. I have the super tuner and Bassani pro-street pipe but need to pick out other parts. My riding style is not terribly aggressive, just looking for a bit more power. Top HP is not my main concern.

Anyhow, I need to decide on:
Cam
Roller rocker
Pistons
Anything else?

My builder strongly suggests zippers dial hydronic tension and 10.5:1. so I'll go with that. He also will be doing the head work. Not really sure what to ask for or expect with the headwork. THANKS in advance for the help!! :pepper:

You will find all kinds of suggestions here. My on personal one is I would skip the 10.5's. I have a set in my bike and they really limit your cam options. Flat tops and .030 head gasket would give you a wider choice of cams

"My riding style is not terribly aggressive, just looking for a bit more power. Top HP is not my main concern."

You are going to be hard pressed to find a cam that performs like the 255 along with a good pipe & great tune.
Based on your riding profile. I know the 110 is exhaust sensitive, don't have enough experience with the Bassani for performance on the 110 other than they make some noise.

this is a mild 110 build we do a fair amount of:
mild headwork
set compression at 10.0-1
S&S .570`s
this will yield 115/125+ all day,have stock like reliability/dependability.forget the zippers tensioners & roller rockers

115/125 sounds great! any particular piston or head gasket?  Also is the compression you achieve by piston, head gasket or milling the heads?  Thank you for the feedback, I want to get this right the first time, no money for a second shot  :)

My 2014 BO has the following:

Headwork to raise CR
S&S Lifters, 551 cam, Pushrods, Roller Rockers
V&H Big Radius 2 into 2

TQ is 109 at 2000 rpm 118 at 3000 rpm and peaks 3600 rpm, 120  ftlbs
makes 85 HP at 3600 rpm

The TQ curve falls off after 4000 rpm but still 103 at 4500 rpm.

This set up gives very nice ridability.

  The pipe might be somewhat of a hindrance to your build....not that familiar with it but from what I have seen very similar to some of the Sampson crap that kills power.

  Decide if you want to do a bolt in cam or if you want to remove the heads or not.

   If not keep the 255 as there isn't anything that is much of an upgrade @ stock compression.

  If the heads are going to come off there are a multitude of things you can do and it all depends on budget.

There is nothing wrong with the zippers dual tensioners,nor the bypass kit you can purchase with them and they do seem to work as advertised.

heads can be milled to 10.0-1 (using .030 cometic gaskets),getting your build right the first time is nice,dollar wise.do your homework and realisticly come up with the build your looking for

Can't thank you guys enough for the help!   Really narrowing this down

mild headwork - not sure what to ask for here
set compression at 10.0-1 - with above head work and cometic .030 gasket
Pistons:  not sure what to look for here, should they be forged, flattop ect?
Cams:  S&S .570 or other suggestion?
zippers tensioners
roller rockers: S&s

Andrews 54 or 57 cams would also be good choices

Yes, precision cylinder head re-surfacing to establish the desired cc's.
That .570 combo is one we have used here on several occasions as well.
With the exhaust timing on that cam, it'll cool that engine off also.
Works well.

Definitely going with s&s .570 based on feedback. 10:1 sounds like a good choice as well. Any particular pistons??

Hoping to start in next 2 weeks.
