...i believe the TVS is a roots design with an additional lobe; a whipple or lysolm screw uses a fundametally different compression topology...
FDCT? Rad!:evil:rotflKinda drips from the tongue doesn't it?
Fundamentally Different Compression Topology
I think I better get me some of that for my car. Sounds fast.

Of course. I was specifically speaking of the 1.2L Lysholm and 1.2L TVS, as the 2300 and 140ax are about 2x too large for the 2zz. Based on the compressor maps I've seen for the smaller 1.2L units, the differences are largely in the noise. I have a 1.6L Lysholm, unfortunately there was not a good TVS option available at the time I made that decision.Depends on which whipple/tvs you're talking about for comparison, the whipple 140ax flows more air than the 2300. it stays more efficient at higher compressor rpm than the tvs.
Perhaps you missed the comment from my earlier post.They're based on the same tech though, they're mostly around the same for all intents and purposes, neither one is drastically better than the other, i've yet to see a conclusive technical study thats shown one outperforms the other by any decent margin.
I haven't seen the same figures from eaton on the tvs as from lysholm either, they've been a little bit less forthcoming on some of tests and how they were done as well as what they're measuring. Lysholm have been off doing other things and haven't really updated it much, i wonder if they will introduce something new to outside world.
I think at the power levels we are looking at there isn't a whole lot of difference. ( Other than cost, but then i don't know the current pricing maybe thats changed too )
Not at all, i was just adding my own POV to it, as well as the additional points.Perhaps you missed the comment from my earlier post.
