I'm basing my hesitation to believe the 2.5 #s based on his mods.
98 2.5 liter SVT:
MSDS
SHO-shop Y
2.5" catback
xcal2
63mm TB
K&N 3530
Quaife
SpecII
UR fly
Nima UD pullies
Mustang dyno:
Max Power: 211 hp
Max Torque: 174 tq
vs.
As a basis for comparison, the day the dyno on my (former) 3 liter was done, several other SVTs dynod and put down typical Mustang dyno numbers.
Here's an example of a dyno of an SVT from the same day as mine:
11/13/04
2000 2.5 liter
MSDS Jet-Hot coated
MSDS y-pipe Jet-Hot coated
Bassani exhaust
Extrude Honed Power Flow UIM
K&N intake
Mustang dyno:
Max Power: 171.6 @ 6750 RPM
Max Torque: 145.3 @ 5500 RPM
vs.
Date: 11/13/04
3.0 hybrid
Ported & polished heads
SHM long tube headers
Extrude Honed Power Flow UIM
65mm throttle body, optimized
AFE 8" filter w/ heat shield
Bassani cat-back exhaust
Torsen LSD
SPEC Stage 1 clutch
SPEC flywheel
Mustang dyno:
Max Power: 202.4 @ 6500 RPM
Max Torque: 177.0 @ 5750 RPM
I'm not calling this bs or anything, I'm just having a trouble believing that a 2.5 with much fewer mods put down more than a heavily modded 3.0.
