ghott Posted July 19, 2012 Posted July 19, 2012 Figure'd I would post this up for shiz and giggles. This was a dyno test done by Corey on the old ATV Tech.net web site...his SN was #8TRX450R I believe. I THINK this test was conducted back in 2007...or there abouts. This was a cylinder head swap test only...the ONLY thing changed between all these runs was just a cylinder head. All of the heads had "Recreational" porting...not Race or Pro (dunno if any of them had epoxy in them or not). The test bike was a 2005 TRX450R - stock bore/stroke/carb. If I recall correctly, the mods on the test bike were: - 13:1 piston - intake ring (sparks I think?) - hot cams stage 2 - dasa classic The heads tested were: - Stock - Venom - Baldwin - Sparks - Rage - DASA http://www.offtopic.forum/uploads/imported/2012/07/headtest_allhp-1.jpg http://www.offtopic.forum/uploads/imported/2012/07/headtest_alltq-1.jpg Take these results with a grain of salt. I'm sure everyone's porting techniques have improved greatly over the years and if this was done more recently...the results might be different! Again, I didn't conduct this test...just posting for info and discussion only because I had saved the graphs from way back then.
