I want to put down #'s like this :(The TVS blowers dont make a lot of noise out of the box, there is a nasty 11-14 TVS car that runs at our local track that has a small pulley and it screams. I would certainty put more into your decision than sound however.
Twin screw will generally make a higher peak horsepower number but the TVS will have torque on its side.

I hear ya, Phase 2 shouldn't be too far out. Phase 3 will follow.

Can't wait! Just hope each phase isn't $5k

For reference in the past P1-P2 $799 and P1-P3 $1499 so it shouldn't be quite that bad depending on how high they go with P3, there have been talks of a P4 possibly as well.

My TVS setup doesn't have much blower whine but I'd put it up against any whipple setup running the same boost. Any takers? Nov 14th in Rockingham or anytime in Charlotte. Let's get some real world comparo's instead of all these dynojet #'s.
Along with a new EO? After all, changing the pulley smaller than tested requires new testing.

Looks like I'm going to wait for the Phase 2/3 release before I decide on which kit to buy. The Torque of the TVS is very appealing. Thanks for the Input guys. I know which ever kit I go with, I'll be more than satisfied.
We have real world comparison's, IAT2 is SIGNIFICANTLY different. And while some can post 1 dyno graph of something they are working on. The fact is, it's already available LOL, it comes with every one of our kits. Nearly 150hp more! A year later, other's have to regroup to try and compete.
But, how are they going to compare with IAT's on these phases 2, 3, 4... Maybe just run it closer to the edge of failure to try and make the same power? There will always be supporters of both, but anyone doing the research will realize:
1. Bigger, more efficient supercharger.
2. Front feed minimizes restrictions, allowing higher VE's.
3. Bigger intercooler trumps the undersized GT500 based core.
4. Far greater flowing intake manifold minimizes pressure losses. As flow goes up, restrictions increase in the smaller manifolds.
5. As power goes up, belt issues can arise. Having a custom tensioner, enclosed in a casting is much more troublesome then having a HD tensioner with an adjustable idler that allows the variance of nearly 1" in pulley changes.
6. Optional 10-rib kit, carbon fiber components, dual 11" spal fans and flash tool with wheel/axle ratio changes (IDS doesn't change that).
7. Calibration light years ahead, better drivability, better safety, better manners and greater power.
8. Massive heat exchanger. No need to upgrade, already included. Research the size difference. Better temp control, quicker cool downs, less power loss and more consistent power. A dyno pull doesn't show all the real world temps. Poor heat exchanger and manifold design shows its ugly head more on the road then a chassis dyno.
To be accurate, the only time a TVS makes more torque is when it can't keep up at the higher compressor speeds to continue making power. Just look at the graph of the "maybe" available, falls off on the top. It would be easy to duplicate this, in fact we have in the past, we just cut the throttle a little on the top and we can make all the torque and lack HP. One of our old systems had a poor intake design (my bad :doh
and it had similar curves, acted as it had "boost" control to some degree because the kit efficiency would fall off on top, but would make great torque. The difference here, there are no restrictions, therefore you are maximizing both torque and HP. Look at the curves of the two..... We've tested both manifolds and intercooler setups. Back to back with our supercharger, 65hp at the same boost level (12.5psi). As flow goes up, the greater the difference. Since we had to use that manifold on previous applications, we have a tremendous amount of testing data. Therefore, when we built ours, we already knew of all the issues of that setup.
The fact is, you can be a leader or you can be a follower. While some may be scratching at the drawing board trying to compete, were already working on the next level of upgrades that will further separate us from the pack.

If you ever come down to Tampa, I'll put mine against your TVS anyday. I had a chance to buy the tvs kit for a lot less than the whipple kit and I'm really glad that I went with the whipple. Honestly, your living under a rock if you think that the tvs kit out performs the whipple.

Not accurate. While the it's not a huge difference, there is in fact a difference. But, you have to factor in the manifold, intercooler, inlet, heat exchanger, MAF, filter.... as its a "kit", not just the SC in this application. You can have an amazing supercharger, but you need to surround it with some good parts as well.
