i disagree,
to qualify equal length headers as the only means to power increases is misleading to say the least.
--I never said that. What I said was simply was no matter what exhaust system you use on a 'naturally aspirated engine", the main limiting factor (in performance gains) will be the design of the header system. That's it. I also went on to say that the Log manifold that Triumph employs due to cost and production restraints is a very inefficient means of extracting spent exhaust products. No where did I imply that equal length headers are the only means of extracting more power. When you increase the incoming fuel/air charge, you must increase the efficiency of the exhaust extraction method. That's simple physics.
a good look at the overall picture is needed to see what i am saying. all you have to do is ride a bike fitted with predators and triple k&n's under the bear claw/tune boy tune . there is not one iota of similarity in one to the other. you can say what
you may,but i find the difference very evident. i weigh 279 lbs. i can pull the front wheel off the ground by simply rolling the throttle on.
--I suspect at 279 pounds, the revelant position as to where you physically sit on the seat may have something to do with how well the front wheel lofts also.
i don't mean to infer any argument here. there is none. a predator system will leave you in a much more satisfied state of mind than any thing that is of stock configuration. i had raask, d&d,jardine, and tors. i cannot,repeat; cannot say in good faith that equal length headers will outperform the predators in their current configuration. the reason being is that predators have been designed for equal flow.this is done by bending and tuning each pipe for overall flow symmetry.
You must be arguing with yourself. The Predators are designed for equal flow.....just what I said in the beginning.....?
dont take my word for this,just look for yourself on the putfile site. you will note the the color of entropy is equidistant .this can only be accomplished through tuning each cylinder to run at the same temperature throughout the power range. this can't be done without good flow symmetry,albeit equal length or otherwise. with proactive engineering thermodynamics,you can have good usable power without the convoluted complexity of equal length spaghetti pipes. aesthetic appeal and tire ripping power is always a good thing. they're called predators,get em whilst you can boys.......
Geeze....more of the same. If you want to give Sam kudo's. That's fine. Sam and I have had conversations about his exhaust system and my hat is off to him for the R&D and the execution. What exactly is your point?
