There is always something to add to the list. I am comparing the tvs 2.3 to whipple 2.9 so this is one of the threads that helps people like me make important power hungry decisions.
It is comments like this (and me trying to make similar comparisons) that made me decide to put together an official database for SVTP. It's an online form that each of us can fill out with information about our engines, blowers, boost levels, pulley configurations, fuel systems, etc. and then, of course, our dyno numbers. With enough submissions we will really be able to compare different setups apples to apples, find out which blowers are the most efficient, what kind of gains can be expected from common mods, and what kind of supporting mods others are running to support their power. Each submission automatically gets added to a spreadsheet that anyone here can view or download anytime to reference.
It's been finished for about 3 weeks now but I just haven't been able to really spread the word yet. Check it out, add your information, and let's see just how much more badass these TVS's are compared to the twin screws!
