That's about what people I know are getting from those mods, damn impressive. A big h pipe with cat deletes gets about 430 too.

Re: 2011 Mustang GT 414 RWHP / 391 RWTQ

I was shocked when it made 414 rwhp it started out bone stock with 366 rwhp
after the mods I was thinking 390 - 400 at the most.
Have to thank Pat Steeda.ca's owner/tuner for the work the shop did on my
car, feels like a whole new beast !!!

Wow that is a nice gain for the items you added.

What is next to be added I know you will want a high number now right?

Re: 2011 Mustang GT 414 RWHP / 391 RWTQ

Axle backs have shown little to no gain in power..

Them numbers are kinda high,. Alot of cold air/tune/LTs/full exhaust have only made 415-420. A lot of it is all about the dyno used and making there dyno's to read a little higher.

With that number are just number. What counts is what it runs at the track. With 420whp you should run a mid 11 pretty easy. I know a bunch t hat have did with that power. Track times show if you really making that power.

Example. Friends car made 450/404 on a dynocom and 429/397 on a dynojet. Its mods are custom tune/Steeda cold air/Boss intake/Headers/off road x pipe/Magnaflow catback. With that power he ran a 11.6@118 in DA of 3100. His corrected time is a 11.2@121.

Density Altitude.



Some one in cold is lower then some one in heat. Or some one in The mountains running is a lot higher then those at Cecil.

Also why you can see two cars with same mods run two way different times at one track in TX and one track in PA for example.

If you can run some where with negative DA it is always better.
