Looking for a list of mods that yield the most improvement per $$
Example:
1. exhaust, $300/30hp
2. cold air intake, $200 /25hp
3. headers $800/75hp
4. supercharger $7000/300hp
I'm not saying any of these are right , I'm asking what is your (all members) priority?
Thanks

Use the search feature, it has been discussed MANY times here. It really depends how radical you want to go and how much you want to spend. NOS will get you the most HP for the cost.

If your looking for bigger numbers look at a supercharger, moderate you can do headers, cam (nice rumble) and tune. Good luck

Yep... you cannot add all that up and come up with a sum total. The first 3 you mention, will not net you near 130hp. Maybe 45-50rwhp with headers/CAI and cat-back exhaust and tune which is about 75-80fwhp max.

It is how much do you want to spend. I'd consider a cam, full exhaust, CAI and tune... you can gain as much as 100rwhp easily, and even more if you go with a more radical cam. Still not cheap, cheap...but its a great start.

Cold Air Intake, Larger Throttle Body, Cat Back exhaust and a Dyno tune yielded me Approximately 480 HP...402 HP at the rear wheels.
Then I added a Vitesse throttle control.
Next I will get headers hoping that might take me to 500 Hp.
If you have an automatic transmission a cam will require a stall converter.
Hope this helps!
Cheers.

Personally I would start with the headers since if you do any of the other stuff particularly a supercharger you will want those any way

Thanks to all for the suggestions.
