Default True Horsepower gains for popular mods.....

Part vendors make unsubstantiated claims. Other improvements move the horsepower way up in the rpm's so the car may actually feel slower around town. And since your engine is a system you may not realize the full potential of a particular upgrade until you do something else. All that said, here's a shot at estimates of horsepower increases for some popular modifications:

Underdrive pulleys -- 5 to 10 hp
Cat-back exhaust -- 10 hp
Headers -- 10 hp
H-pipe -- 5 hp
K&N-type air filter and remove air silencer-- 5 hp
Throttle body -- 5 to 10 hp
Intake manifold -- 15 hp
Don't forget about gears. No HP increase, of course, but the most performance bang-for-the-buck

Agree with most of the above with the exception of:

Throttle body: No more than 3hp unless it's a 331 or 347. Maybe nothing on a near-stock 5.0.
Headers: Shorties ~5hp, Long Tubes ~10hp.
Intake manifold: Depends on the replacement unit. GT40 good for ~10hp.
Underdrive pulleys: Crank pulley only ~5hp, complete pulley set ~10hp.
1.7 roller rockers: ~5hp.
C&L 76mm MAF: ~5hp (~10hp with cold air kit)

^^^^^ yeah you are probably right

but the purpose was to show the comparison of real and advertised hp gains...

just a very general post.....

Absolutely right. We know that the claimed HP gains from most parts manufacturers are grossly overinflated (the claimed 20hp from the Helix Power Tower probably takes the cake). Fortunately the 5.0 has been around for a long time so the myths have been busted by real dyno numbers.
Maybe the moderators could stick this thread so that Mustang newbies can have a reference when it comes to starter mods. I think it would be fair to say that you would gain about 40-45rwhp from a package of traditional basic bolt-ons consisting of CAI/MAF/TB/pulleys/LT headers/midpipe/catbacks/1.7 roller rockers on a previously bone stock 5.0.

HCI would be better and not a huge difference in cost with greater gains in power. Or do all

Very possible it could be stuck, what other examples can we all add to this?

Heads/cam/intake are certainly cost effective but you still need the basic "stage 1" bolt-on stuff to make them work. You could consider H/C/I as "stage 2" either after you've done the basic bolt-ons or do the whole lot at the same time if money allows.
Eagle, I'm sure I could dig around and find some HP gains for heads or H/C/I packages.

not a true horsepower gain

you can pick 1-3 rwhp......

Might be sliding off topic here - What about a reduction in chassis flex and better weight transfer?

once again very good this doesnt give u more power but this allows more power to get were u need it by applying pressure in the right areas allowing for better tracktion and less wheel slippage

before i did anything big, i did the suspension. i noticed a huge difference. I went from losing to my friend from the start and by 6-7 carlengths by 3 gear to being in front through 1st and 2nd and only losing by 2-4 carlenths depending on the race. I also did the basic bolt-ons at the same time at the HCI combo, but I picked up most of the parts for very little. It worked out great for me.

Very good idea. I'd start by posting some of the proven dyno test done by MM & FF. They've done the heads, intakes and various engine combonations (sizes and levels of builds).
