looking for some info on a set of power inc. center dumps.what would these pipes work best for as far as application?drag? mountain?trail? i have ran the end dumps, and the benders, but never the center dumps.kinda curious what they would do for me.i know the rpm is maxed out at 8200,and my sxr needs 8400 for max power, so are these something that i can use for a specific application, or am i better off with the stock pipe over the center dumps?from most of what ive been reading, most people when drag racing say that you wanna leave the line at about 8200 rpm, and climb to peak rpm, 8400-8500 at the end of the run.are these pipes worth putting on?could they be used with heavier weights to get a better holeshot?and how much hp would they make on a stock sled?thanks in advance, brian.
I would not think they would perform well for drag racing. I think they where more for a triple trail pipe. Aaen hauck cpr simmons benders psi power inc end dumps would be a better performing pipe
Leaving the line at 8200. Seams pretty hi to me but I could be wrong

probably leave the line at about 8000, and 8200 at the finish.

with the center dumps.
Ok think I might have looked at the wrong way. Thought u were talking engagement at 8200. U are talking running shift out at 8200 and finishing at 8400 right ??
Center dumps are more of a trail pipe in my opinion.

probably 5000 engagement, and around 8000 on launch, then 8200 on the top end.my sled makes the most torque at 8200 rpm.should pull hard all the way to 500 ft.

im building a grass drag sled for epping nh this year.want to be competitive with the f-7 sleds!!!
Definitely more of a trail pipe/midrange, but if you already have them than I would try them. I have both (center and end) and really like the centers. You can run them up to 8400. It's all about sled setup with these. We have almost two identical sleds set up for trail/crossover and one is a 136" trail ported center dump and the other is a 144" un ported end dump and they are very close. Both 2' paddles both 8 tooth drivers and lower gearing, roller clutches. I think the centers get a bad rap for no reason. Used in the right rpm they rip.

im gonna give them a shot,cant hurt since i allready have them.just gonna clutch it to where i get the quickest et, and play with the gearing.what are you running for jetting?
