That is very cool. I never knew they had a simulator. Nice find, +rep.

 

Hmmm, touche on that. I haven't seen the maps but I take it the TVS will be the most efficient?

 

Well I just told Danielle that I want the TVS for my birthday, and she said it's the new blower or our honeymoon... Guess I have to step up my overtime now.

 

The M62 and Twinscrew maps don't even go all the way to 2.4 PR, lol. So that says it all.

Then again, these things don't even exist, so I am willing to bet those TVS maps aren't 100% and are probably exaggerated.

 

not only does it have a greater peak efficiency, but it has a better overall efficiency through the rpms. A turbo uprgrade may produce slightly more efficency at certain rpms, but in no way are turbos 85+ % efficient, I need proof to believe that one.

Anyways it would be awesome to have a more efficient supercharger because superchargers have much more controllable power curves. With fwd you don't want that crazy torque steer when boost starts to spool especially when you're cornering where it may even cause you to lose traction.

 

Ah okay. I'm still learning, so sorry if I said anything to upset/confuse anyone. I'm not even sure how to CORRECTLY read the maps. I know how to somewhat. Thatnks for the correction.

 

Who doesn't like torque steer? Joking aside, I really do agree with having a smoother powerband and its bonus on FWD cars.

Numbers to prove that ? According to new TVS maps, it might be UP TO 70% efficiency, but at a very limited boost ratio range. Not even close to a good turbo.

 

You can look at it the other way around and say any given turbo would be beyond the surge line at high PR/low flow where the TVS is efficient at 2.2pr at extremely low compressor speeds all while maintaining a relatively high choke point, something a peaky turbo isn't capable of.

Edit: Necro-bumped this one looking for any new TVS release info.

 

This is a double-post (https://www.cobaltss.net/forums/show...&highlight=tvs), but given the amount of interest in TVS I hope the moderators understand ...

This is certainly an interesting thread ... and one that I can shed some light on. My name is Ken Nunn & I am the General Manager of Harrop Engineering in Australia.

We manufacture superchargers - both twin-screw and Roots. We have been doing so for many years, and can say with a lot of confidence that the TVS-based supercharger is very impressive. We build TVS-based products for two OE-ish companies: TRD & Roush. Before choosing the TVS units, both companies did extensive & independant back-to-back testing which resulted in both companies being convinced that the new TVS-technology was worth the extra expense.
In the TRD test which I observed, the TVS1320 produced more boost at a lower temperature with less input power required (parasitic loss) than both the 1200 twin-screw and the Eaton 5th-gen M90. It was also quieter.

We have just completed the tooling for our generic TVS-based range of superchargers. The initial release is know as the HTV range (Harrop Twin Vorticies as TVS is an Eaton-specific trade-name (for Twin Vortices System)). It includes the HTV1320, HTV1900, HTV2300. All are availble in a range of mounting options and input-shaft lengths. We use the HTV2300 on Chev LS1/2/6/7 & L76/92/98 engines. The HTV2300 can support 1000+ HP on an LS7 ... as done by GM-Performance/TA-Engines in a Solstice!

Also ... and the reason I have joined this forum ... is that we are currently completing the design of a HTV1320 bolt-on upgrade to replace the old M62. We have no intention of doing a "complete kit" (we will leave that to your local experts). Our solution is an HTV1320 supercharger that is a direct bolt-on replacement for the Cobalt SS M62. It has a pulley supplied on a hub for easy changing, and has the OE integral bypass assembly included.

It is our intention to have durabilty testing completed by Christmas, and the production release available in January. We are not a sponsor, so it would not be appropriate for me to indicate pricing or distribution ... but you guys can always make suggestions

 

^^^The only I didn't like about your post

GREAT NEWS! And here I was about to give up on the Supercharger!

 

Definitely great news.

 

Hm, this sounds like a nice upgrade. Where's Santa's email addy at again..........

 

We have been keep up on the TVS and the TVS tecnology on LCN since October. Thanks to CTCobaltSS for gathering all the info and sharing it with us and finding THIS great vendor info.

 

x2 to this. I wonder with an intake if this bad boy will scream just as good.

Thanks for the updates, this looks like a simple, and efficient swap for us. I am looking into this majorly.

 

I'll just throw a 2.6" on it right away!!! Haha

 

Did you know the old M90s put out 90 db out the inlet, and 120 db out the outlet!!!

 

No... what does ours do with a 2.8"? Haha

Interesting Facts though.

 

subscribed.......

 

i hope it sounds as good as the twin screw

 

I'm waiting for this release badly.....this will cap off my mods.

 

They already said it was quieter than a Twin Screw and Roots...

 

thats kind of disappointing if its quiet

 

Usual ricer .net. If it isn't loud, it isn't fast.

This thing will eat a Twinscrew LSJ, and from looking at the maps, possibly even a lot of the Turbo LSJ's.

 

is this a direct replacment?
