[QUOTE="CD07GT500, post: 15497688, member: 195665"] First off I would like to say the TVS is a great blower and works well for it's size. Also this test was done with a none R version. I went 9.88 @ 144 with the Gen 2 TVS but like most I wanted a little more. I had already maxed out the Gen 2 and did not know if a $1000 port job or the new R would be worth the money for the 20-30whp gains that I have seen. So I sold it and took a shot at a 2.9 whipple crusher maxed out like the gen 2 was. Not many people have pushed these 2.9 blowers on a stock motor so I was little unsure on it's capabilities. Anyways here are the results and I was slightly surprised. Both pulls were on a DJ STD correction on a 29" 10.5W bias ply with 17lbs in them, . TVS GEN 2: 2.4/15% ~23lbs. Crusher 2.9: 2.5/15% ~27lbs. Everything else was the same bolton mods and fuel (C16). It was a little cooler for the crusher pull but I did not ice it down for the pull. The crusher had 2* less timing for anybody asking. [MEDIA=youtube]XiZiZtYYw6Y[/MEDIA] Here is the whp graph it picked up 61 at peak and as much as 90 in the mid range. [ATTACH=full]702409[/ATTACH] Here is the tq graph the TVS has a advantage in the lower rpm (2500-4000) but after 4500 the bigger blower has the advantage. [ATTACH=full]702410[/ATTACH] [/QUOTE]
