what does an intake thing or manifold do?

feeds more air to your engine. it's connected to the throttle body, which in turn is connected to your air intake.

cool.... i could use one in my stang when i get one... most likely wont use it because i think an air intake and new throttle body is good enough but its still an awesome idea. currently i cant afford a supercharger but any other ideas for mods to enhance performance are welcome

The plenum and throttle body are only really useful once you've already modified your engine, but the thought of opening her up more is definitely a good one

When you're talking about forced induction, after it's all said and done, it comes down to your tune.

What kind of car do you have? If it's a 2v or 3v mustang, DO NOT buy bolt ons (heads, intake, cams, etc). You will see very minimal gains. Only way to make those fast is some juice or forced induction.

i dont know what you mean by 2V or 3V im planning on getting a V8 mustang (8 cylinder) and putting on some nice exaust nice headers, an intake, a new throttle body and lowering springs.

what do you guys think of this engine:
ROUSH Performance - Engines

Well what year are you planning on getting?

2005

It's a SOHC 3v. Throttle body and exhaust are fine. Just don't expect great gains from bolt ons..

2V and 3V are the number of valves per cylinder head. I have never owned a Mustang myself but I know the one to get is the 4 valve, it allows for more efficient flow and ultimately more power potential.

what do you mean dont expect great gains from bolt ons... what stuff would give me good gains? besides a supercharger

Ford has different levels of greatness when it comes to the Mustang. 2V, 3V, and 4V engines are all offered throughout the years, but yes, the 2005 is a 3V.

3V means 3 valves per cylinder, which there are 8 cylinders.

3 valves x 8 cylinders = 24 valves.. so on and so forth:
2 valves x 8 cylinders = 16 valves
4 valves x 8 cylinders = 32 valves
yay math!

When talking about Mustangs, more valves = more hp and potential. The ones with 4V are Cobras and Mach 1s. The newer GT (05+) is 3V, and older GTs are 2V (like what I have).

The single over head cam 3 valve motors like in the 05 you want do not respond from boltons very well. Which means you won't get very decent gains. Get some gears for the rearend (3.73 or 4.10), exhaust (headers, midpipe, and catback), and leave it be. Everything else will be a waste of money, trust me. Now if you had a real mustang things would be different

The main thing you need to look at, is NOT how much MAXIMUM power you can put out. You put any car to their max and they don't last. You need to look at the fact of what type of driving style are you looking for. The hard thing is you can't argue which is better a super charger or turbo, they both make power only in different ways. Both require some time with tuning, fabrication, installation, and many others. The claim about super chargers taking power from the engine, LESS than what your alternator would take to turn. If the setup was designed for maximum efficiency then that would be the perfect setup. My personal opinion, I could go with either, depending on the vehicle. The later mustangs have so many aftermarket kits for them, it's hard to chose. If you have either one set up right, I have seen both on the Mustangs, and both were fast cars. You just need to look at what type of driving do you want, cause it can't be a drag strip and a street car to pick up groceries. The problem you will find with Fords, they have designed their engines, intakes, exhaust, all to be MAXIMUM EFFICIENCY not power. Meaning many bolt ons or add ons will not give you the power you might expect. Some may just make it noisier and sound like it has more power. Find a dyno and run it before anything, then after you are done run it again to see the real results.

how could i modify my engine to have 4 valves? im sure something like that could add more power
