I did not have dyno before these mods. However, Ed told me they;ve dynoed stock M5 and M6 around 385-395.

That's on our DynoDynamics dyno though. That's not going to translate directly to Mustang or DynoJet.

Last week when I talked to dyno dynamic guy who working on dyno at RPI, he said dyno dynamic read similar to dyno mustang and 10-15% lower than dyno jet.

It seems the difference between SP Engineering's dynojet
and RPi's dyno dynamics is around 5.4%. This would put a run of
424.3 at 401.4hp on the RPi dyno. That seems in line with
what we've been seeing. I'd also note that the fans they
have at SP aren't as strong.

My guess is that you'd probably be around 407ish (things being
nonlinear). That seems to be what the M5's are doing over
there with the scoops (excluding Gabe's freak). I think Eloy
is doing a meet and greet in January sometime.
You should come out and test your luck on the RPi humiliator dyno.

Would love to. Spoke with Eloy couple times, seem to be a really really nice guy.
