I just got back from the dyno. I was hoping for some better numbers. But i guess this is probably pretty normal. I have just been seeing so many high HP numbers with people from the same mods. I was thinking it would be around 260rwhp.


Here is my info:

1st dyno last year with Borla cat back, welded in X in place H on stock pipe, Underdrive pullies----> 236/278 hp/tq

this week i added: Accufab 75mm TB/Plenum, Demolet CAI, Catted magnaflow X pipe, and XCAL 2 mail order tune by MPH.

Todays results: 250/290 hp/tq

So obviously all the claimed no's by companies are no where as high as they claim you will get on a N/A 4.6L car.

I read on here somewhere, that you shouldnt go right after you install new mods because your computer/car needs to re learn and get the max out of the mods. Any truth to that? Think it would get any better?

That sounds about right. A full bolt on GT will be in the 260 range. You are doing pretty well.

Actually, most hp claims by companies are for supercharged applications, i.e the 03/04 cobra. You did about expected for the mods you have, just makes you want to mod more, huh?

thats about right i've got the same mods you have and i dynoed at 254rwhp and 302rwtq.

i'd say if you got some long tube headers you would be close to 270rwhp or alittle above that.

Yeah those #'s seem about right. Looking pretty good, better than my puney 225 at the wheels [:@]

Did you get Tim's N/A tune??? if so how is it because i was seriously considering ditching my hypersuck chip and getting the N/a Tune from Tim at MPH with the xcal2

I should have those mods by the end of summer. Hope I get 250...

not really. i got a whopping 6RWHP from the claimed 12+ for a tb/plenum combo

So much for people arguing about TB/Plenum getting you upward of 20-30hp. HAH
