HP guesstimate...

[cedp83]

Hello everyone, I'm new to the site. I'd like to know if somebody can estimate how many horses (crank and rwhp) my car has with the following mods, I know the gears nor the clutch gives me any hp but how about torque?

2003 Mustang GT:
K&N CAI, King Cobra Stage II clutch, Power Programmer III, BBK shorty headers, MAC O/R H pipe, Flowmaster American Thunder 40's catback, 3.73 Ford Racing gears.

Finally, how much more will tune, BBK TB/Plenum, MAF, UDPs, cams, nitrous 100 shot will add?
These are some other mods I have in mind for next year... any advise?...opinions?

Thanks,

Carlos

My guess would be 240 ish. Those shorty headers dont do much

I have virtually the same mods you have (K&N CAI, Flowmaster American Thunder 40's, and an SCT tune) and my car put down just shy of 240rwhp/280rwtq through an auto.

Your headers are worthless (maybe 2-3rwhp, if that) and with an O/R H I'd say you're around 245rwhp.

With the addition of a TB/plenum and UD's you should so around 250rwhp. My advice would be to not mess with the MAF. The stock piece is fine for now.

Cams = 280-290rwhp

100-shot of giggle juice = 340-360rwhp/450+rwtq
100-shot w/ cams = 400rwhp/500+rwtq

240/280 through an auto with those mods is great

on a more serious note , the hp would hugely depend on how the cams of choice , but i would say mid 240ish without the cams and touch mid 270 with one , 100 shot would put you around in the 360-380 zone depending on the nitrous kit since some kits rate at wheel and some at the crank , torque would be hard to predict but i would say high 400s , hope this helps.

A stock motor with a 100 HP shot will produce torque of over 425 @ 4000 RPM. The lower the RPM you spray at the higher the max torque.
