TW-555
10.5 CR
FM Level B Heads
FM Adjustable Pushrods

MGS True Duals
Arlen Ness Big Sucker
FM Power Vision

Before and After on same plot. Before was just the "Stage 1" (MGS pipes, Big Sucker, PV)

109.77 HP, 126.69 TQ

Up from 78.18 HP, 95.51 TQ.

 

Can I ask total cost of the kit, install, and dyno?......for future reference

 

All the component prices are on FM's website, I think.

 

Congrats to you dude !!!! Incredible gains....30/30 in both tq and hp . If only I live a little closer....

 

2001 RK
95", SE 204 cams
Stock "fiddled" carb w/SE intake
Hooker tunable slip-ons, left closed, right open
hydraulic tensioner kit
81hp-99tq

Can't get new Hookers and these are rusted through now...

 

Here's my build: 09 FLHTC, 103, SE 255 cams, SE air cleaner, Freedom Performance true duals, Power Commander 5, stock map.

Just had the bike dynoed yesterday. 86.21 HP, 101.66 Torque.

Was hoping the HP number would have been higher, but the torque number is OK I think for only some very basic mods and no custom map.

 

well. mine is finished for now.
10.5 909c kb pistons. gtp heads. tw-777 cams
fatcat exhaust and a/c.

she made 95 hp and 106 torque.

i think that this dyno is a bit stingy dont you? she runs much better than other 95 hp bikes i have been on

 

It used to be the case that HP and TQ numbers in a good tune were the same, but more recently larger TQ numbers are becoming normal, which goes hand in hand with higher low/mid range torque. That is what gets us moving off the line fast and passing traffic effortlessly! Our cam designers and engine tuners are changing the shape of our torque curves for the better.

 

SE 110"
SE Cams 260
SE 58 mm TB
SE heavy breather
V&H Big shot duals
(thought the numbers would've been higher for my setup.?)

 

Put a good exhaust on it and you'll see some better gains. You have to big a TB, especially for those pipes. Your HP flattens out around 5k RPM's which is a sign that your engines not breathing very good. A good breathing build should show the HP climbing all the way to the rev limiter.
