Mike sent me the tune and it does have a tranny tune in this one. About 11-12 lbs of boost. I did a couple test hits, wow its wicked. I will get in the 9's, don't know if it will be this year or not. We shall see what it runs at Topeka and go from there. Its gonna be pretty hot there, but not like it was at the Camaro fest.

Hello all, new the forum, first post here, just wanted to introduce myself and get a quick opinion from the experts. I picked up my new Camaro (only has 500 miles on it, just purchased last month) last night from the performance shop. I'm amazed at the power it put down on dyno HP wise, although they said the torque didn't track correctly on their machine so I have to come back at a later date for a dyno redo which I intend to do in a month or so when the weather starts to cool. It was humid and 100 degrees yesterday in the shop. Long story short, my car put down right at 600rwhp (599.85 to be exact). This was done with a magnuson heartbeat sc, a "10lb" pulley, stainless works long tube headers/high flow cats/x-pipe connected to factory mufflers and of course a custom tune. My question to the experts here (because I am still new to the 6th gen SC'd world) Is that about what you'd expect with my add ons or better/worse than you would expect, and what kind of torque should I expect to see with this set up when I return for my dyno re-run? Thanks in advance

If I don't have to move then I am going to rent the track down here as soon as it is cold enough. You have a place to stay if you can make it. - DA for sure.

Txc, welcome and enjoy the new power. Expect to run real fast with a good drag pack setup. Yours made great hp at 600 rwhp

From what I can gather on the new TVS 2650, it is basically how the D1 procharger is to the P1? Overkill for street use but if you are going for big power gains and drag times, should have it? Do correct me if I am wrong, I am after all just curious

Kind of right, kind of wrong...

The obvious is that the 2650 will provide more headroom, especially for larger ci engines. As we all know, it's all about airflow... the more air we get, the more fuel we can burn. However, there are more advantages to the 2650. Eaton advanced on the already great TVS2300 rotors and made the 2650 rotors 15% larger (2300cc vs. 2650 cc), requiring 18% less power to drive the rotors, 25% more air flow at 18,000 RPM and 14 psi boost (2.0 Pressure Ratio)
72% isentropic efficiency vs. 68%, and overall 4% more efficient. So you will still see an advantage on stock ci over the 2300 variant, however the real gains will be achieved on larger ci engines. Of course all this data still has to be put to good use and it takes an intelligent mind to make a suitable housing for these rotors and mate up to our cylinder heads. A challenge im sure Magnuson will have no problem with....waiting for the release

From a flow standpoint:
TVS2300 (1600 CFM) ~ F1 Procharger or 2.9 screw
TVS2650 with Magnuson "Race" housing (2500 CFM) ~ F2 Procharger or 4.0L screw

But from a usage standpoint, air delivery from a PD SC is linear so the sizing is not nearly as critical is it is with a centrifugal. A 2650 will run just fine on a street driven low boost engine, granted at low speeds the 2650 will be a bit softer (less boost) than the 2300 will deliver.

TVS 2650 will be more expensive and really not provide a ton of benefit compared to the TVS 2300 unless you are looking to go over the 800 RWHP mark.

Remember that the EATON posted numbers are based off an OEM style housing designed for low speed performance and NVH, a couple things that aren't really quite as important to those of us in the aftermarket world.

There are multiple versions of the TVS 2650. It will be available for the LT1/LT4 Corvette and Camaro as a completely under hood solution for these vehicles, but due to tooling and casting complexity they are a but further out in the timeline.

The jackshaft 2650 for Hemi, LS, and LT will be earlier to release but will not fit under the stock hood of a Camaro or Corvette.

Mike, thanks for your input. I didn't want to say too much because I wasn't sure about any time lines.

Thanks a mill to the both of you for the very informative posts! I was kind of right and kind of wrong haha. I did figure the TVS 2650 would be more pricey than the 2300, let's see how much of a difference. By grabbing the new TVS 2650, at least you would have a higher power ceiling if you do choose to pursue it in the future and not be blocked at a certain hp range by the TVS 2300 since it sounds like both will be just fine for street use. But then again, it really does depend on the price difference...

Another thing to add is that even though I do see and appreciate the quality and top notch work of Magnuson and TVS, the current TVS 2300 is such an extremely well established system now, especially for our 6th gen... For me, it would be really hard to just grab the new one before it has been established for more than a year like the current TVS 2300 is. Haven't heard a single person complain nor have issues about it which; sadly, I cannot say for ANY other FI system out there.
