[GMR-PERFORMANCE]

The builds are all the same parts the only changes are ex systems. ALL runs are done at 185+ engine temps.. Stock head one to another will vary but you get the picture. Over all not hard to build a tq monster on a budget.  Not looking for any other ideas. I was asked to post up a sheet with these all back to back to back..  If you have something to say about how this other 113 kit works lets see the sheet in SAE or dont waste any ones time.. ( you know who you are)

Gmr 113 kits , our 577 cam lifters and pushrods. Stock heads and t/b


Overall avg is 113.36 HP and 128.72 TQ

RED=         Fulsac C pipe with crusher mufflers

BLUE=      V&H pwr dual with V&H high outputs

Orange    Fuls sac C pipe with fulsac 1.75 core mufflers

Nice package, consistent results

Looks great Steve.

Great info, sure shows exhaust choice really affects low end. I never thought you would see close to 20 ft. Lbs. difference!

[GMR-PERFORMANCE]

Well peak numbers tell one story and the curve another..

Now lets toss it all into the blender and have people who can type, but do not tune efi  , can make suggestions that they have no real idea what the out come will be once let alone several times in a row. Other than  a statement on what they have witnessed.. So did they really see it or did some one else tell them about it.. and if they really did see it was it all on the same dyno with the same parts more than twice??

LMAO Thats funny right

The entire reason I would rather see the same shop with back to back and yes even back to back again  data. Take out the peak number penis contest, look at the curve and decide it that is your bag of cats , if one would use that term..

And to that I say have a great freaking day   


Just messing around  its good data and thats that..

I really like the curve for the Fullsac C (red) vs. the other 2.

Yes sir. My buddy Stu has those crushers. Him and Sachs love those things.

It's definitely the Crushers Jesse. When Steve had mine he showed me how they compared to my V&H Twin Slash Rounds and it was a no-brainer to go with the Crushers.  My final curve looked a lot like the red one. I get compliments all the time about the sound of my bike now. Maybe because since Steve worked on it most of my riding buddies are behind me.

I like the torque curve of the crusher mufflers also. But I already have the V&H power duals with the V&H Hi Output mufflers. I am headed to see Steve when I fly in from offshore on February 25th. I plan on going with his .600 cam and his 113 build with the hopes of that torque curve possibly getting a little broader on the low end. Maybe crossing that 120 mark on HP? Fingers are crossed.

If you don't want to buy the Crushers, don't let Steve show you the difference they make!! 

Or better yet, MAKE him show you......you can always do what I did and sell the V&H's.

So do I.... Headed down Saturday to pick up the bike and it's suppose to start snowing Sunday. 

Probably be another week to share how it runs.

[North Star]

Thanks for the very useful and very real info Steve- I know everyone appreciates it. 

Yes, I think this shows what a difference mufflers can make on the curves.

I'm running 4" Rineharts with my build. My torque curve comes on early and stays pretty flat, which is what I like.

I'm thinking of switching up mufflers though. How do you think the following would perform in comparison to my Rineharts and each other:

Bassani DNT
RCX 4"
Crushers

Thanks.

[CircleRacer]

Are the mufflers the Mellow Crushers??
