2011 5.0L Coyote Power Adder Comparison Dyno Chart

1- run005= Paxton Novi 2200 - 8-10 psi (cutting off early)
2- run009= Hellion Turbo - 8-9 psi
3- run011= Roush TVS - 7psi
4- run062= ProCharger D1SC - 12-14 psi

All were on 93 Octane

All manual

All on 80+ degree days with same humidity

Factory boost levels and pulleys that come with the kits.

After playing with the tune to make it more aggressive, we are adding a BOP to make it more fun!

too bad they are all at different PSI


can you tech this up with some spec/explanation of why the power is different

Why was the Hellion car shut down at 5.5k?

The first 3 are at least close in boost but the D1 is obviously running a lot more and not really a fair comparison. I like the chart.

On the hellion what rpms does the pull stop at? Hard to tell with all the lines.

Are all these cars manuals?

Just a tease. Get a BAP on there and get back to us.

600 ft/lbs of torque !!!!!

550 rwhp at 5,000 rpm on 8psi - :naughty1:
Should be interesting to see what it does at 7,000rpm

ts amazing to me that the turbo make the most torque at the same boost levelsby far too

Nothing amazing about it. All the missing torque on the s/c dyno graphs is being used to turn the blower. Just shows how much real power a super charger does consume.

Not trying to be an ass, but why does that amaze you? Which power adder did you think would make the most torque?

Turbos have and alwasy will make lots of torque in the mid range when using a properly sized turbo.
That is why they are so fantastic for street machines

That's not it at all. It's that the turbo is the most efficient, and that it hits full boost at peak torque, where the centris are still building boost.

And it looks like PD > Centri at stock boost levels.

Should have all been at the same boost 8-10 is quite a range.
but turbo's always make more torque.

Turbo>supercharger

Not for all applications. Just look at the torque and power curve on a whipple or KB supercharger, constant power, all RPM levels. Every s197 ive seen with the stock block the twinscrew superchargers have gone fastest in the 1/4. once you upgrade it to handle the added power then a big turbo or twin turbos take the cake, mostly due to effeciency I believe.

I dont agree that they should be at the same boost levels. Boost does not have a direct relationship with power or the load on the engine.
The flow characteristic of the compressor play a key roll. Like for instance, there is a big difference between 10 psi on a gt30R and 10 psi on a gt40R.

Plus, an engine will take more boost from a supercharger without failure due to the high exhaust scavenging, which is reduced greatly with a turbo. A centrifugal compressor (either turbo or super) will allow for more boost due to the higher thermal efficiency.

I would be more inclined to see dyno plots where all the setups have had the boost fitted to a particular peak power level, as this is a test of the shape of the powerband, not how much power will be made overall. ANy of these units are capable of making more power than the bottom end wlll take.


Also, Im disappointed that you didnt get the Hellion cars fuel system up to par before posting this information.
