Hi,

wanted to get some feedback I recently had a SS 110 kit put on my 09 Street Bob. Also heads ported and machined and compression set to 10.7. Put HPI 55mm TB with 5.3gps injectors. I already had a woods cam TW-8-6 in my bike. Exhaust is new Thrashin AR 2-1 stepped. Was dyno tuned with Power Vision and both power & tq came out to 122.

I thought id get more with this build so just wanted some feedback from experienced people on here.

Thx

 

Post a pic of the dyno sheet, sometimes that can give a lot of clues as to what's going on.

 

heres the dyno sheet

 

To be honest I’m not very educated with dyno sheets but I’m at 122 tq on a se 117 kit (259e cams 9.9:1 comp, 5.3 injectors, and 58 mm throttle body). I also had it dyno tuned with powervision and have a fat cat exhaust. I thought I’d get more power out of my setup as well

Considering you had headwork done, I also would think you woulda gotten a little more power out of it, but I don’t think your numbers are low by any means sither

 

does it show the air fuel ratio ?

 

no it doesn’t

 

I have almost the same build and got 122 Torque. I think that's about right and figured that's what I'd end up with when I planned the build. To my knowledge, the biggest Torque factor is cubic inches and compression. Seems the porting, cams, etc helps more on the HP end.

 

You should post this in the Dyno Room. Someone hanging out in there will be able to decipher it for you.

 

good point will do

 

Throttle body too small.., and the cam questionable
