whoppes27 Posted April 13, 2012 Posted April 13, 2012 Thought I would post this up to add to the new form. These were back to back runs with a dasa pipe and a barker pipe. Dyno conditions could have been much better but regardless it still shows the difference in the pipes. Mods at the time were: 2006 450r ss/sb Racers Edge port with +1 valves x4 crf head gasket Web fbc 208/921 13.5 cp piston 42.5 fcr taper bored 110 sunoco Stock intake with a k&n Green/red are Dasa Black/blue are Barker http://www.offtopic.forum/uploads/imported/2012/04/stdruns-1.jpg Quote Racers Edge Powered 2006 trx450

whoppes27 Posted April 13, 2012 Author Posted April 13, 2012 Ohh duh, how'd I forget the cam. It's a fbc 208/921, I'll add it to the list Quote Racers Edge Powered 2006 trx450
Dr. Beardface Posted April 13, 2012 Posted April 13, 2012 Nice comparison! I've always been curious about these two... Quote 2004 TRX480R 30+ HP
Guest Phantom Z Posted April 13, 2012 Posted April 13, 2012 Whats the price comparison between these two pipes? Quote
whoppes27 Posted April 13, 2012 Author Posted April 13, 2012 There very similar in price, probably within $50 depending on who has which pipe on sale. Quote Racers Edge Powered 2006 trx450
manny530 Posted April 15, 2012 Posted April 15, 2012 nice comparison this was an uncut dasa? Quote EVERYONES FAVORITE MOD!!!! http://450rhq.com/data/MetaMirrorCache/f7e22d28ca03559ff7236e85f6128ca5.jpg
whoppes27 Posted April 15, 2012 Author Posted April 15, 2012 Thanks, this was a full length pipe. Quote Racers Edge Powered 2006 trx450
manny530 Posted April 16, 2012 Posted April 16, 2012 wonder if the shorty dasa would show any improvemnt? Quote EVERYONES FAVORITE MOD!!!! http://450rhq.com/data/MetaMirrorCache/f7e22d28ca03559ff7236e85f6128ca5.jpg
whoppes27 Posted April 16, 2012 Author Posted April 16, 2012 wonder if the shorty dasa would show any improvemnt? I bet it would pick up 1-2 hp but the dunes I ride in MI require a spark arrestor and they also have sound restrictions (stupid, I know) they have been letting me slide by without a quite core though. If I have the pipe cut it might be too loud. Quote Racers Edge Powered 2006 trx450
whoppes27 Posted April 16, 2012 Author Posted April 16, 2012 Since these runs Ive been tuning it on e85, removed the air box, added an fci intake, and replaced the completely worn out chain that was on it. If I'm not in the upper 50's to 60 I'd be pretty disappointed. Quote Racers Edge Powered 2006 trx450
Guest Deven Posted April 16, 2012 Posted April 16, 2012 Shortys show improvement on some motors but not all. seems to be that not all motors like the shorty. Would be interested in seeing though. Good comparison. Quote
whoppes27 Posted April 16, 2012 Author Posted April 16, 2012 Yea john almost gave me a cut dasa for this test instead of full length can but we thought this would be more fair for a comparison. If John runs them with his port work and motors very similar to mine, I would expect a cut dasa would show a gain on my build, but your right, unless I tested it theres no way of knowing.
