hooker tuned flow
I'm considering changing from v&h classics to hooker tuned flow mufflers on my 95" road king. I'm curious about recommendations for tuning the pipes. Should I opt for horsepower, torque or inbetween? Which setting produces the best performance sound? Technically, what happens when you adjust to hp or torque? Thanks.

RE: hooker tuned flow
jstartz,
Drawing from my knowledge of car drag race engines...in similarly prepared engines torque wins drag races every time except with very high RPM engines (which V-twins are not). Torque is what gets the bike (car) moving from a dead stop or slow speed. Horsepower comes into play at higher RPM's. Most V-twin street bikes operate in the 2500-5500 RPM range. Horsepower effectively begins its influence roughly around 4000-4500 RPM's. That leaves you about 1000-1500 RPM's where horsepower really comes into play. Chevy High Performance Magazine has done a couple articles regarding this issue, with comparably prepared engines except one engine was set up with slightly more torque and one with slightly more horsepower. The higher torque engine consistently won over the higher horsepower engine. Go for what is most effective at the RPM range you'll be operating in. And for the overwhelming majority of us with V-twins...it's torque. For Japanese and other "in-line" engines that operate in a much higher RPM range it's a different issue and a whole different subject. Hope this helps.[8D]

RE: hooker tuned flow
Sorry that I can't help you on tuning specifics, but I do have a tuned Hooker 2 into 1 on my '02 Fat Boy. What a difference! Runs smoother, better idle and an additional 14 HP. But they were installed and carb adjustments were made by some dyno pros. They set it up for mid range power and there's a world of difference over the old setup. And the sound is killer. I used to think that my V&H Big Shots sounded so great. They were a ratty blat compared to the low growl of the Hooker. I highly recommend them.

RE: hooker tuned flow
Do you need a pitch pipe or a pitchfork? And talk about another disappointing thread heading. I haven't read about the kind of hookers i was thinking about!
And I had some great ideas about fine tuning them!!!
Seriously, these sound like awesome pipes. Keep the reports coming. Art
