2003 cobra power numbers?

Second off the poster above me is correct. If you get a ported TB/Plen and decent cai and exhaust system that flows well, and a 2.76 upper and tune you will make in the mid-high 400s to the tires.
I would not go with a aftermarket tb/plen. The stock one flows really well once ported and the money you spend on a aftermarket piece can be used to port your eaton instead which will gain you another ~50-60 rwhp instead of the 5-6 from a aftermarket one.
If I had 4-5 grand and a stock term I'd grab a used exhaust and intake off the forums, get a used kb or whip for a few grand, get a used bap & 60# inj and tune it. You'll make ~600 and can call it a day. (the price is factored in the fact you'll sell your stock stuff as well)
I've had almost every setup you can have on this car, sept a twin-screw, and the only reason for that is I can't with the turbo as well.
If I had to do it again I'd go twin turbo or a twin screw and nitrous.
Everything else is a waste.
If you swear to the holiest of powers you want no more then 600rwhp a port and nitrous will get you there easily but it's so much easier doing it with a twin screw. Everyone tries to be a hero with the eaton and a decent amount end up upgrading to a kb or whip anyways.
Don't touch the fuel tank, get a BAP and big *** injectors. If you run out of fuel sell the BAP and drop 2 grand on a return setup. I speak from literally trying every returnless setup on the market and still going return.
Don't be a hero with the returnless system. It'll only be a money pit. Some get it to work but more have problems then don't.
In closing with these cars power is SO easily had for such a CHEAP price that you should always upgrade big. Don't upgrade to just barely do what you want, always spend extra so you don't have to re-do the whole thing when you want to make more power down the road.

My numbers are in my sig and that is pretty much with every bolt on including longtubes, I do not have a tb thou. Alot of your power also comes down to how well of a dyno tune you have. I am hoping by changing my intake and adding a tb/pl I can make 500rwhp with no port, twin screw, or n20.

I found this site and it has just about every mod and horsepower figure you can dream of. http://dynofacts.com/category.php?ty...b82f84955d1e30
Having said that I have a stock plenum that has been ported. Who, where, and how much does a ported throttle body run?

I would send my blower and tb/plen to posi, he'll give you a great deal and you'll see max gains, prolly around 60-70rwhp once you're done over stock.
Can't go better then that if you plan on running eaton. Then spray it with a 150 shot and call it a day.

i agree with timpspony...i have many buddies that have kb and its a very good supercharger but i find myself hearing less horror stories with whipple then kb...and people will fight this all day i wouldnt be upset with either set up but i would choose whipple specially cause it a direct replacement and kb you have to do a couple things.
