Well, my tuner (modular powerhouse in Alpharetta) just dyno'd an '05 GT...
This FUGGIN thing just laid down 279 rwhp, 300rwtq STOCK ... a/f was way rich 11:1 ... says with a tune (more timing, less fuel) this beast will hit 300 rwhp... STOCK!
Guys, the '05 GT made more hp than ANY stock Mach1 he's ever dyno'd... O...M...G
Unbelievable. Ford seriously undertuned and underrated this mustang. With a REAL tune this is a mid-low 13 second car with drag radials.
I stand "somewhat" corrected... although untuned its still no where near a mid 13 second car on street tires... a 13.9 would be impressive. This car, afterall, is like driving a semi down the track with that extremely un-aerodynamic front end - but the power... for reference a stock 99-04 GT lays down about 225 rwhp
