I won't say its guaranteed, but I'd be really surprised to see a propipe robbing torque unless you completely took the baffles out.
In my future 98" build with my heads decked to match the compression on the cams I;m choosing, I'm expecting 110+ running my propipe. You should get at least that on a 103.
Have to say I agree. I simply cant see how a set of pipes is going to rob nearly 15ft/lbs
This is for my 2009 Fatboy and is now a 103 motor. Heads have flowed and ported, larger valves & springs, 52mm throttle body, S&S 625 cams, 10.5:1comp. V&H Pro pipe. I will be changing the exhaust soon back to the original header pipes and S&S turbo slip on mufflers. Then off to my Dyno tuner.
good result anyway, 116HP running all the way to 6000
some cams produce figures where HP>TQ, the 259e also has similar no's where HP>TQ
is the builder in Adelaide?
do you want something just to go from light to light
Doing this on my laptop in the garage so no scanner or copier. 2011 Fatboy Lo. HD cases bored to accept S&S's 124 kit; heads are 110 HD massaged by Dan Vance; Woods TW408G-7 cams; HPI 58 throttle body with 5.3 inj(if memory serves me right); S&S dual runner air intake; rb racing 2 into 1 exhaust; HD roller rockers; SE cam plate and oil pump; SE comp; SE clutch plate; Baker 7 speed; etc. Made 128 HP/132 tq. A few more vibs but fun to ride. Tuned by Trask with SE master tune.
