i recall that article. BUUUT, surprise surprise, eaton is making a TVS3100 now! lol. They already have a few prototypes

 

I don't have any videos yet but heres what 2k's sounds like

this^

taking the TVS 2300 vs the TS 3100 is a stupid comparison - taking the TVS way out of its efficiency range when you try to up the boost to the same level as the TS

didn't know that they were making the 3100 TVS already... got any links?

 

i want to know the specs

 

no links, but it was displayed at SEMA this last year



but no more thread jacking.

 

^VERY nice...

my plan is to buy a 2010 camaro ss and put this ^ on it...

 

I have a feeling that this twinscrew 1.6 blower is gonna create insane amounts of heat.

 

^ This is what I'm curious. I wonder if Meth + other cooling mods is going to be required* to run this no matter the pulley.

 

the cooling mods available now will be enough to cool it...throw a nozzle on it.. maybe an option B tank

id throw the nozzle on anything blown..personally

 

^ I agree. Meth is great for cooling and reaching higher potential. Blowers love meth lol. I don't have a problem running it, I just made that comment because I feel like there are some who want to stay away from it. When the TVs first came out, I saw many threads with questions about when to run it and what's safe etc. All I'm saying was I think with a higher displacement blower like this, it'll be a requirement more than anything for efficiency purposes. Still looking forward to what's to come

 

u could be right.. thatll definitely be part of the testing

 

Looking forward to it. I think if all works out well with the application, install, and tuning then this 1.6L TS is going to be putting out some great numbers and a beautiful powerband along with it.

 

id run it to 8k too... obviously not on stock motor.. nuetral shafts, 78lb valve springs

 

You would need a dual pass, opt b, large HE, meth, and a seperate large cooler for the blower to keep temps to a manageable level, ethanol helps to bring down the temps too. It would also be advisable to port the throttle body or go bigger, ported head, full 3" intake and exhaust. With a twinscrew you do not need to run it to 8k...6600-7200 is fine.

 

Surprisingly... not really.
Compared to a TVS, it will run warmer at the low end, due to the constant compression... but up top it will be about the same.

I'm not sure who can recall the old RAW tests... on a stock cooling system they were running 120-130 on a 20+psi pull.

 

I stand corrected.

So, in real life terms, what set-up would make the use of this 1.6l twinscrew blower more practical and smarter than the TVS? We've found that revving the TVS into higher RPM's with ample supporting mods proves to be the trick to using it. Now what about the 1.6l TS? High boost applications?

 

TVS is way past where it should be run at high boost. The twinscrew is just getting warmed up.

 

The Internal Lubrication System will not suffice for our application. A Circulating oil system is necessary due to the constant compression and higher boost at low rpms. Temperatures on my car soared to 200 degree iat 2's with out the additional cooling mod. With the added cooling, temps are managable and high boost does not have a significant increase in temps as with the eaton.Being that the 1.6 is bigger than my 1.2 you would need a pretty big cooler to fill up the front...I will have to look at the 1.6 performance characteristics to calculate the btu's.

A proper designed bigger twinscrew kit would be a great choice. Its for people who prefer an application for which engine response and power are more important than any other consideration.

 

its all about pricepoint. when ottp can sell their stage 3 kit for that low. u can't expect to get more then 3 k fot the 1.6 ts

 

thats only the case if they are comparable in horsepower numbers. The idea here is the twinscrew will be capable of making more power

 

if im not mistaken whipple makes a 1.6 blower the ax1600 and i do believe someone did put one on a cobalt once

 

From what I've seen on other vehicles, the twinscrew is generally more effective at boost levels above 15-16psi. However, the TVS has proven quite stout up in to the 20psi range.
Theoretically, the twinscrew should be good for another 6-8psi on top of the TVS, before getting into a dead zone for losses and heat.

To put it into a perspective relationship; where the M62 loses steam (around a 2.6"), the TVS takes over.... where the TVS starts to top out (around a 2.6-2.7") the twinscrew should pick up.


The 1600AX is a lysholm blower. (1600 meaning 1600cc/rev)
Whipple claims they will make one... but have never actually produced a single unit. That one is the W100AX (meaning ~100ci/rev... actually 98, though).

 

You put it into perspective very well.

In your opinion, do you think it will be easy to make those high boost numbers with the 1.6l twinscrew? For example, one wouldn't just slap this blower onto the car and BAM instantly be making 25 psi efficiently. Let's prepare a "mock" build, if you will. If you had this blower in your hands, how would you go about modding the LSJ to prepare for it besides the obvious choices like cooling mods, injectors, tune, etc?

 

When getting into the high boost situations, it will require some extensive mods to handle the power and pressure.
I would personally go about building the engine, the same way as I'd build for a high power TVS;
- supply the fuel; large enough injectors (like 80's), enough flow from the pump (pump rewire, or replacement), and maybe a good pressure control mechanism (via return style).
- let the air flow; get a good header, DP and catback. Get a reputable intake system.
- cool it down; pressure makes heat. Get a dual pass, and a good heat exchanger... look into methanol injection.
- deal with the pressure; at high boost, the springs will float, and the head will lift. ARP head studs, and higher pressure springs are a must. As well, the plugs will have to be colder, and gaped properly to avoid blow out.
- deal with the power; are the rings going to handle it? How about the pistons? Plan for a potential failure.
- dial it in; get it tuned. You want everything to jive just right. One mistake can mean catastrophic failure when your pushing that much airflow... you don't want to lean out, or knock.... a tune will fix that.
- put the power to the ground; look into proper mounts (rotated), a good clutch, and maybe axles. Power is useless with a blown clutch or a busted axle or transmission.

 

Good example.

You touched all of the major points and addressed them accordingly by including which mods you would go with, why you would use them, and a cause of failure. There should be more posts like this.

So nothing too extensive. A ported and polished head would be a nice addition I would think. Maybe some forged sleeves for added protection. This is good information.

How about a picture of this blower? Just for reference purposes.
