I just got news from the PO of my bike. My bike dynoed at 98.6rwhp on fastbikes (michigan based company) dyno. What about you guys? What kind of numbers have you run?

 

I think a list of mods is in order also. I will have dyno numbers in a few months. Gotta get new plugs and exhaust leaks fixed. Lol.

 

Details below are from Arrow website, and the Torque / AF ratio was because I asked customer services nicely,

 

Jardine rt one slipon
not sure on the air filter???
no power commander

 

Good numbers wizard. Are the actual runs or just to show the improvement you can get with that exhaust?

 

They are the runs that Arrow perform during their testing phases,
note they are DIN


The main bit I like is the 4250 - 6000. notice that the flat spot is almost gone and added by 4-6 hp, this I can feel in the real world, the bike does not need a fist full to set off.
It is so smooth. I can set off and the accel is pulls all the way with no slow bits,

When you look at the pipe close up you can see that they are works of art,

From the headers the pipe is conical in shape and the link pipes are in a higher postion, then after the link pipes again they expand in a gradual conical shape.

they meet under the bike and again it is a concical shape to the muffler, The 4 into 2 into 1 postion is moved so that they are in a differing place.
All these little changes make the differnce between a slip on and a full system. You really have to see the detail to appreciate it.

I would have no hesitation in spending this money again for the ridability that I have gained. This is how the bike should be from the factory!

 

How much did you spend on this exhaust?

 

I did 94 WHP on a portable dyno, just to see what the number was. Slip on, air filter, untuned PCIII. Gonna get the PCIII tuned this year, should be around 100 or so.

 

i dyno'd @ 97.5 after my tune. mods are in my sig. suprisingly, i only picked up .5 hp after the dyno tune but it is smoother now.

 

errmm about £700 GBP ish

but dont tell the misses.
