Was currently running ,pc3, fuel moto jackpot slip ons, and k&n airfilter.,, {bike is 07 electraglide} when the pc 3 was installed at my indy with the setup as listed my dyno numbers were a lot better. Something around 79 hp and 90 ft. Lbs torque, they mapped the pc3 on their dyno. Well , last friday i had them install ,andrews 37 chain drive cams and s&s adjust. Push rods, looking for a little more torque as i do a lot of 2-up riding,,, and the shops mechanic suggested this setup. So after the job was done they put the bike on the dyno to re-map the pc3, when they were done , they gave me the run sheet and my numbers had dropped to something like 85 lbs. Of torque and 78 horses. My bike is still there as im not real happy losing power and think they need to re-tune or something. Any ideas as to why this may have happened??? I am not trying to win a dyno shoot out ,but just concerned as to my numbers dropping after spending the money to boost my torque a little, and end up loosing torque.. Any thought would be appreciated, and thank you for your in put..........

 

How did they look overall? It's ok to give up a few peak numbers if they increased the curves overall... Just my thoughts.

To be honest, your first numbers sound a little high.......But there is no way you lost torque over stock cams unless they didn't get the oil pump back together right and it is wet- sumping, or they didn't do them at all...Make them check the crankcase, there should not be more than about 6-8 ounces in there.

i dont have the sheet from the run after the cams and new tune, there still at the shop with the bike,, i only have the sheet after they put the pc3 and air cleaner on. im not sure how to read those sheets i look at the afr, and the peaks numbers.. its hard to see the torque line , but this was after the pc3 and air cleaner

 

I would agree. Looks like a sheet with 255 cams.

 

Was the early dyno from the same shop?
It's in STD which shows a lil higher numbers than SAE would.

37's should do a lot better than yours are.

 

the dyno sheet that is showing, was before the 37 cam install,, the sheet showing is from last year after they put on the jackpot slipons, the hi-flow a/c, and the pc3 on... i dont have the sheet with me that has the #s after the 37 cam install. its with my bike at the shop. but i remember the numbers were in the area of 85 or 86 torque and 77 or 78 hp. . im afraid maybe that they dont have the push rods adjusted properly. i fess up that i know nothing about doing this type of work, thats why i took the bike to a shop that i thought knew what they were doing. i had some reomendations from several people about this shop..i just believe that my numbers should not come down. but i appreciate your thoughts and help. just , looking for answers and suggestions to take to the shop when they open on tuesday morning.

 

Screw numbers, how does it ride? If it wicks up and moves that big bagger down the rode, mission accomplished.

 

i really like your answer, unfortunatley , i wont pick the bike up till tuesday, they were gonna do a re-tune late sat. evening, and i want to make sure the wrench checks those push rods again.. i know just listening to the bike yesterday just idling, it sounds a lot different...

 

your 1st chart has a nice curve, good numbers. same shop, same dyno and lower numbers after the upgrades? i wouldn't be happy either....
