Default Eaton 2300 vs Eaton 2650 engine dyno results (Video)

Hi guys,

I was talking with Bob (3 Z06ZR1) the other day he told me about this engine dyno comparison video of the 2300 versus the 2650 supercharger. Even though we probably won't see these exact Harrop supercharger manifolds over here in the States I think this gives us a good guesstimate of what the 2300 and 2650 rotor packs are capable of whether they are in the GM housing, Magnuson housing, Edelbrock housing, etc..

The supercharger housings will obviously make a difference, whichever housing that has the most efficient airflow and intercooler design will likely make the most power.

Enjoy the video!

FOr what itís worth...
65mm upper is a 2.55 and the lower appears to be factory, so itís roughly 8.0

that puts blower speed around 20,300k at 6500.. sweet spot from what Iíve seen out of a 2.3 is 23-24k, so a little more power could be made

I thought the bigger throttle body would have made more of a difference power wise. Maybe the velocity stack they used is that much better than any CAI available?

I wonder what kind of drive parts you'd need to turn the 2650 that fast. More ribs for sure. At some point, that thing will become an eater of a lot of the driveline parts behind it. I guess it's a good problem to have. It's not like it will be a slug at moderate boost levels though.

Are you spraying meth when spinning those rpm's?

I agree though, if you can spin that blower to 23-24k and keep the IAT's down there is certainly margin for more power.

Great vid that has been posted around for a while now! Harrop only released some of the info though I'm sure! It would have been nice to have seen the IAT difference at a fixed power level.

Either way if you can get the 2650 to fit it's going to be a beast of a blower!

965 vs 1069 Only 100 more from the 2650.
Then that max effort would take a lot of supporting mods.
I'm looking for 720 rwhp or 800 hp or so

I have the 2300 on order but was still researching the 2650.
So I called Edelbrock today and the Supercharger tech guy said sorry but no plans for a 2650 coming from them for the Z06. Too big It will not fit and would require a different hood.
He said to use the 2300.

Whipple saying the same thing but someone got their 2.9 to fit (with cutting).

Like you say if the 2300 is in you goal range then great go for it! It's bolt on and will offer more cooling as well as more power than the stock unit.

The max power of the 2650 was over 1100bhp... think you might have missed the last pull with the smaller SC pulley...

TVS 2300 is a great setup for up to 900 wheel, its what I have on my C7 Z06 and it's perfect for that setup.

The Maggie TVS2650 is a whole different animal, made 1153 RWHP yesterday on our 6th gen 416ci LT1 Camaro SS, it's at the low pressure fuel system limit again with about 20% more left in the blower. Should go 1300 wheel once everything is up to snuff.

What fuling mods have you don't to the above setup? Take it that power was on E85 or was it race fuel?

We will be at the track over the next couple weeks to start getting the car dialed in. It went [email protected] with 730 RWHP, but I'm sure its gonna take some time to get the chassis to deal with another 423 RWHP.

Awesome build, this car sounds amazing.

E85? What compression ratio is that 416ci? 12.0-1?

Thanks Eddie, Compression Ratio is 10.8:1 and it's currently running on VP109. I had hopes of running corn, but we ran out of low pressure side at the 1153 level. Once we get dual intank pumps we'll revaluate the E85 option.

Since we drive the car on the Hot Rod power tour we'll be doing a pump gas cal as well - would like to add the E85 sensor and see where we can go to with an active flex fuel system.

Be nice to see what the beast could do on all 3, ie pump e85 and VP109!

Oh and I hope Magnuson, and Eaton for that matter, are sponsoring the F'ck out of you! Lol you are the best advertisement for both I have seen in a long time!

We have a Fuel Line Pressure kit with a Flex sensor we are running on Ben's compound boosted '17 ZL1 with direct/port injection, if you would be interested in one of those? The standard one is rated for 1000-1200rwhp and our upgrade version is rated for 2000rwhp. (LOL Because there is no such thing as overkill.)

What controller are you guys using for the port injection? Is it Flex capable?

Holy mother of god, that double-barrelled blower looks fukin Gangster!
What a monster.
And itís still gaining power through 7,000 RPM! Whereís all those centri-centric folks that say PD blowers run out of breath at high rpm??
