Installed my PPE Engineering header - Page 4 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Our Mustang dyno reads approx 20% lower than the Dynojets in our area. I have compared our Mustang to the load dyno used at HG Motorsports and our numbers are always within 5whp. We are also running CAN91 fuel, which is the worst piss water available in the Con US. Pull is also 4th gear (5th is too tall and takes too long to load up on the dyno) so gear ratio is not 1:1. More power in 5th.

A stock BRZ/FR-S usually makes between 130 and 140whp on our dyno.

Numbers aside....there is still a significant drop in torque over the 2800~3900 rpm range. I would have thought the headerback plus tune would have at least flatlined the dip area?

I could have the graphs mixed up. I am not pulling them from the dyno workstation/database but from a file on my desktop. I dont have all the notes on my desktop file. I wont be booting up the dyno workstation again until Saturday. I have 1 more graph on my desktop that has a nice flat TQ curve (for a N/A car) and I could possibly have the two graphs mixed up. I have A LOT of BRZ/FR-S dyno graphs, lol.

If the flatter curve is indeed the PPE headers, they are the only headers we have dyno tested that actually flattened out the TQ. All others have FAILED to do that. S/C or turbo will flatten it out.

Here is the other graph I might have mixed up.

We'll find out on my car just how well this header does with an SC/IC.
