Dyno Numbers and Video Finally

dyno'd Jan12th 05
70Km's Legend Lime Mustang GT
272.9rwhp at 5100rpm
307tq at 4100rpm
A/F was 11.5:1

BONE STOCK! Really awesome results! thats a 01 Cobra dyno # and there is room to grow at 11.5:1.

These will be quick cars even N/A!

This is great news.

my 99 Cobra Dyno'd at 291 and 296tq Stock (after the re-call)
I'd say those numbers are bang on to a stock Mach1 though.

ya 291rwhp is quite high for a 99 even after the fix... actually thats insane!
01's average 275. 99's after recall about 265rwhp. Saw as low as 258rwhp.

Regardless 272. with only sixty Km's and rich at WOT is a great place to start from! the TQ is up there too

sorry it did have a K&N on it...but I also had a very good mechanic that had it tuned right in...once i put the timing adjuster/pulleys X pipe and exhaust it hit 305 RWHP where it capped out. :bang

Those are some nice numbers to start with
the aftermarket on these cars is just starting to blow up now...imagine a yr from now. Very nice...when do get the blower...lol
