I was wondering if anyone could give me a good guess on what kind of horsepower my car has. I have a K&N cold air kit, diablo tuner, andflowmasters. Thoseare the only performance parts I have. I do have 20 inch rims which weigh more then stock (each rimweighs about 25 lbs).just wondering if anyone have their car dynoed with this set up or know a could estimation.

A cold air kit and tune will yield 25-30 rwhp. This is very common for that kind of mod.

You will have 285-295 RWHP.. Thats what my 06 had and the wifes 05 with the same mods...

Going off other cars I have seen on here I'd say you were in the 280hp range. But depends on tune.

Caution

That's kind of a hard question to answer as our stangs are all different not to mention the tunes being different as well ... if I had to guess then I would say about 280ish give or take -- mine dyno'd at 265 bone stock[:-] .

The canned diablo tuner wont add the same HP as a tuner from bama or brenspeed, hell i barely noticed anything with the diablo tune...and the K&N isnt the best CAI......you are losing HP with the 20s and the exhaust will add nothing.

Honeslty you might have 15 HP over stock but maybe not even that, but those arent the stongest mods you have...

I have a 07 gt,manuel tranny and 3;73 gears.C&l cold air,brenspeed 91 tune,pypes cat back with violator mufflers.I have been on a dynojet,mustang dyno,and last week a new dyna pack.The a/f is 12.8,314 lbs torque,300hp.I am looking at the charts as we speak.max rpm was 6250.I am running 20' tires,and have time slips at 12.6@107mph.

If you want to improve your performance in reality the 20 inch tires are a no-no.

Looking good White, Like Dan said, the only negative I see in your Sig. would be those 20 incher's.

Yes,the 20' tires took all summer to master.They have no side wall or grip.I was running the same times on 17' drag radials,and wanted a new challange.My first pass was a 15.2.Car spun bad in the first 3 grears.Our club hits the strip almost every weekend.Lucky to have a good strip close to home.and one that is open every fri.,and sat.night.Only 15 bucks to have lots of fun,and keeps the streets safe.
