Eaton TVS 2650 Rotors

Whipple SC said:

Of course its going to pickup power with the same pulley. 15% more volume or 25% more flow (as advertised), why would it not?

To have the same flow, approximately, you would have to increase pulley diameter .625" which is over 2000rpm difference in blower speed with 15% more volume. 25% would equal another 1500rpm input speed for a total difference of 3500rpm it should be slowed down to actually compare performance at the same boost.

Any larger SC on that turns the same RPM as a smaller SC will displace more air if it is even remotely efficient.

100% agree with this statement. The comparison was geared to show how much more room there is to grow with the 2650 compared to a 2300. Not surprises with the results. But if you are after big numbers the 2650 is the better choice. We currently still offer both versions for the time being.

Is there a video floating around somewhere of the F 150 that went from the 2300's to 2650's?

Does Edelbrock plan on getting data out there? I take you have test vehicles out there, correct?

With respect, the data seems to be coming from places other than Edelbrock. I was hoping to see something from the manufacturer speaking to the advantages of your new product. I don't mean to troll or bash, I am a huge fan of Edelbrock since my Chevy days. I'm surprised by how this is rolling out.

I completely understand and trust me, I am pushing for it. Much of our in-car testing is for validating our complete kit calibration and EO certification, not so much trying to make as much power as possible. We tend to rely on our dealers/performance shops to push our hardware as many do with Roush and Whipple products. We have some projects internally and externally in the works. In due time, more test data will be available.

As you know, Edelbrock supports many different engine platforms for superchargers so time and resource allocation sometimes limits how much testing we can do for any given application.

I will say that we had a 9.5:1 compression Aluminator on the engine dyno making about 900hp with a 2650 TVS. Unfortunately, we found the limits of the factory engine block during that test session so we had to cut it short. We were able to hold 20psi on a max effort run, but power didn't match what we expected. A leak down confirmed the engine was not 100% so we tore it down and found some of the cylinders were out of round. We had to move on to other scheduled dyno testing, but will likely revisit this testing with a sleeved block in the future.

No, I never even dynoed the truck with the 2300. I will have 2650 numbers (on 93) in the next week or so when I get time to put it on a dyno...

Still waiting on VMP to offer this as a bolt on upgrade.

I pretty sure you can not put 2650 rotors in a 2300 TVS..

The Edelbrock S/C box is the same size for 2300 and 2650.

You cannot update a 2300 blower to a 2650, the manifold is different. 2650 rotors have a larger diameter, and are longer than the 2300's...

This is correct. Although the external dimensions are the same between our 2300 and 2650, the 2650 uses a different casting and they are not interchangeable.

Thanks for correcting me. I was told by one of the higher ups at Edelbrock they were the same box but apparently not.

I imagine the shipping box is the same, maybe that's what they meant...
