Question What size turbo(s) can match the Eaton TVS 2650?

Is there a single turbo or pair of turbos that can stick or beat an Eaton TVS 2650 supercharger?

You know your asking a very open ended question. When it comes to turbos, you need the engine size and hp goals and rpm range. Until someone knows that they could tell you a 70, 72, 76, even tell you that you could use a 66mm unit.

That's not really a big blower by what I see in the data I looked at. That blower is about 95 lbs/ min and only supports 2:1 pressure ratio. That would be less than 900-1000 HP at the crank. It can't make all that much boost so you would need an engine that flows good air, you would not be able to push a lot of air through a small flowing engine.

Any turbo flowing 95 lbs of air a minute would be in that power range and would work better on a lower airflow engine. That blower can only do a pressure ratio from inlet to outlet of 2:1. A turbo can easily do 3:1 or 4:1 pressure, so about twice the boost. This would let you make the same power with a lower base airflow engine.

A good 76mm would about equal that blower. A good 88 would make 50-60% more power and be able to do twice the boost or more. That means the base engine power (airflow) doesn't need to be all that high.

Of course there are junk turbos that do poorly for the compressor size, but anything good and over 76mm would beat it.

Can you give further information as to what is your engine size? rpm range? hp goals?

You need to figure out what you're doing for an engine before anyone can recommend a suitable turbo.

I'm going to run my car naturally aspirated for now. I don't know if I really need or want too much power for a street car. It's easy to go overboard.

I have no personal experience in them, but when you say “block cracking power....” does it take much boost to do that to the old 5.0’s?

I haven't done it personally. What I have heard is around 500 hp is the number. I want a fun street car. I don't want something that belongs on the track. I don't want to spend a million dollars on it. It's easy to fall into the "I need more because the ZL1 or Hellcat makes..." game.

a TVS 2650 is a new gen helical roots blower used on the ford mod motors and distributorless LS engines from the factory. People will make well over 1000 with them surely, since they've been doing about that with the smaller TVS's already.

There are no kits currently on the market that adapt these blowers to a SBF and any way you try to make it work will be a massive modification/fabrication project.

When talking about a properly sized blower vs a properly sized turbo, with proper camshafts, a turbo will always make more power. The delivery of that power will be different and some people prefer one over the other, but even that can be controlled in both cases very well now to where they're nearly even (this is in reference to the boost lag people mention with turbos).

For a stock block 5.0, any bolt on turbo kit could make block splitting power. If you get a turbocharger with 66-76mm compressor inducer, a 66-75mm turbine exducer, with a .69-.91 turbine housing A/R, you should be good for block splitting power anywhere from 12-15psi.

The cheapest 70mm will be more than adequate to meet your goals.
