[QUOTE="Iamchris, post: 16243889, member: 21687"] When I had to make the same choice, I almost went with a 2.9 because bigger is better, right? Hell, I almost pulled the trigger on a 2.9 Mammoth. The truth is, that is a lot of blower and based on what others are seeing for performance, you need to spin it well into its range for it to be worthwhile. I scoured the forum and every other forum I could find and compiled as much info as I could. I found that the blowers were actually very similar in the ranges that they shared. The TVS 2.3 in my hack-analysis appeared to outperform the 2.9 just a bit though, making more torque and horsepower, appearing to be a bit more efficient within its range. But that is the thing, there were more cars breaking into big numbers on the 2.9 Whipple, especially with the Mammoth. My aspiration is 600+ on pump, and 700+ on E-85. I found that even then I needed to beef the car up a bit, but not wanting to step up to a Magnum, or build a new motor, I didnt want to make 800+ I felt confident that the 2.3 TVS was the right choice for me based on my goals, it would perform more efficiently to do what I wanted it to do. The only shortfall in my opinion is that you would need a lower pulley to reach the high end on the TVS. I don't recall if that is the case with the 2.9. I would prefer to keep the stock lower, but it is a concession to be made, at least with the TVS. I have all the parts to be installed, I just completed the driveline upgrades though and have a little while for break-in before I can continue with the poweradder mods [/QUOTE]
