Where are the good 2V 4.6 manifolds?

Anybody who has spent the money to make 500 or 600 rwhp is not going to hesitate to spend the money on an intake to make another 30 or 40 rwhp. The only intakes I am aware of are the P51, Bullitt, and Reichard Racing. I think there may be others in the works. For a normally aspirated application, it is questionable if the expense is worth the gain. For example, I think the Bullitt intake is worth only 5 rwhp n/a or something like that. I have a ported Bullitt intake, but it is coming off tomorrow for a Kenne Bell 2.2

So Jim, your finally switching to the 2.2? Good luck, and man i dont understand how you guys can switch setups like I change my clothes lol...does tim give some sort of kickbacks for the old stuff or do you sell it? But for you with everything but the 2.2, intake, pully, and HE...its shouldnt be too much.

"I live in a nice neiborhood with a big house, im a member of the local golf club, and do you like my car? Its supercharged and im changing setups again...How do I do it? IM IN DEBT UP TO MY EYEBALLS....SOME ONE PLEASE HELP ME!"

My point to this thread was to see if there was anything else out there that maybe my 100 searches of the internet overlooked. There are a boat-load of 99 to 04 GT's out there. If a consumer will "pony" up $1300 for a chunk of aluminum, there is A LOT of money to be made to put out a good design for much less money. $500 is realistic for 15whp, and would be on par with comparable modifications. Something pre-tapped for direct port nitrous and enough material for port matching. Something like this. (It's for a DOHC - but you get my point). I do plan on gears, cams, ported and polished heads, long tubes, aluminum drive shaft, or whatever will get me to my horsepower goals. It just seems that there is definitely room for improvement in the manifold area if someone can dermal one apart and glue it together and get almost 10whp. Any entrepreneurs listening?

this guy is giving it a try, he posts on corral frequently and drives a 96gt i think.

one of the other posters bought one for his nitrous setup, still waiting for a install/dyno write up

reichard racing is using pulse technology to 'ram' air into the opposing runner, just like a ford nascar intake. a supercharged 5.4 4v has made 1300 hp with one of those intakes.

10 hp is not worth my time to take it apart. the factory is good enough. they made it right. besides, what rpm are you planning to alter it to work ? 6000? 6500? are you going to cam it and compression it to work there with 2 valves? all that money? for what? unless you are trying to do a 2v only thing, get a used lincoln 4v and use the heads and intake. they are all over E-bay. starting at $900.00. up to $5400.00.

that's my story and i'm stickin to it.

If you don't have serious mods. I would stay with the stock one. But for a heavy modded car Reicard Racing's Intake performs awsome and delivers serious horsepower and plenty of torque yes torque. ....and looks good too. They cost around $1350.00 depending on where you get it.

If you read the mag's you'll find out that they all agree on one thing. Any aftermarket manifold for the 4.6 2v is designed to really show a performance increase if you have forced induction. Look at the designs of them, notice that all of them leave out the air chamber that is required for low end torque on a n/a engine. Now, if you were going to force the air in, then spend the money to do it right. S/C with a new manifold (for high boost), Roots or Kenne Bell type blower will replace the manifold, OR, this is what I'm getting, do a twin turbo set up. With the turbo, you can tune your boost to match the stock, or go all out and spin 900rwhp (hope you can afford lots of tires). Sorry people, Ford did too good of a job on their composite intake...keep it for an n/a engine w/o NOS. Hell, keep it for a moderate blown engine.

You can always save your money on all the mod's, use that plus your car to get the new SVT Shelby Mustang...500bhp stock and warrantied...we should all be so lucky.

From what I have heard, the RR isnt that streetable. A lot of people have drivability issues with it. Its mostly a race only intake and it does work great.

P51, the price scares everyone away. Scares me to. Sadly it would put me over the 340rwhp mark but the price to HP ratio isnt worth me spending 1500 dollars.

spend the money on cams and head work. Most of the aluminum intakes are still not going to give huge power gains , only an aluminum intake that can be ported. Still better for FI applications.

Basically, it's this simple. Your engine is a large air pump. The more air you let in and push out, the more horsepower you can make, by adding fuel. In a n/a application, the stock intake is not that limiting. That's why most people only gain 5 to 10 rwhp with a Bullitt intake. However, once you do enough mods that the intake becomes the limiter, you are going to want to spend the money for an intake. Either that, or it's time for a power adder, or both.

So with some P&P heads, cams, exhaust and all other bolt ons completed...A P51 will be beneficial? I love the look of it and don't mind the cost as long as it doesn't hurt my performance down low? I'm totally on the fence on this I read articles of both satisfaction and some not so satisfied?

Well, yes. The more you get the air flowing, the more beneficial an intake will be. Whether it is beneficial enough to justify the expense is an individual decision, I suppose. I don't know if, in a n/a application, you ever get to the point that your intake is that restrictive or not.
