Highly underrated

Long story short -

FPV quotes 335kW (450HP) for the blown Coyote (codename Miami).

They were referring to the power at the WHEELS! Read on!

Three weeks ago a local Ford-dedicated magazine, "Street Fords", had a
press car for a few days. Their first stop was the strip with a time of 12.92
@ 114MPH (2.1 60'). With the 120kg driver it tipped the scales at 4277lbs.
Traction was an issue.



They then took it to a performance workshop, threw it on the rollers to
record 353rwkw (473.9rwhp)!!!!



They were dumb-struck, off course, so they took it to another dyno the next
day. That reeled off 328rwkw (440rwhp). *Bare in mind, driveline loss is
more than what you're used to in the U.S.; it's (calculated to be) closer to
25% here in Oz.*




The internet arguments started - many were skeptical that this is pulling
over 550 flywheel hp with that Trap Speed.

UNTIL.... This morning, when another reputable workshop got the exact
result. No, not a press car, but a customer's. Bang on 325rwkw. Second run,
tightened down even harder, the GT's ecu pours more boost, fuel and timing
as more heat is detected. It pulled 333rwkw.

One of the skeptics was there.
He did the extra tightening.
He was gobsmacked.

This tuner explained why the MPH was down. The gear changes come with
heavy torque truncations, thus inhibiting the power during shifts down the
strip - obviously won't come into play on a dyno.

A very slight play with the SCT flasher resulted 355rwkw (over 600HP!!!). Not bad for a non-intercooled 1.9 tvs.
