professional products intake manifold 4.6 2v

i personally want the p51 but i havent seen many numbers on that yet either.

i know there is a guy on mustangworld that had it and got rid of it because he swears he lost power. i think its mustangworld....maybe it was here.:shrug:

anyway he had cams too. thats bad, i really dont get that. the only things i saw is that guy complaining and the fox website claim numbers.

also with the bullet's dyno numbers. it cant possibly do must to a gt stock.

however it might give me some power. either way i never see any dynos for any of these.

am i gonna have to buy that heavy ass p51 early just to see for myself, and post up here?

i wish i could but the addes weight before the blower will slow mw down even if it does boost me over 300rwhp.

The manifold itself didnt make 25hp, it was the manifold, AND 75mm TB/Plenum over STOCK manifold, tb/plenum on a car with a built block (unknown compression ratio) Fox Lake Stage 2 Heads, Cams and a butt-load of bolt-ons. There's no way that manifold ALONE gives you more than 10 hp on a stock GT. Im guessing 3-5, if that.


I agree 100 percent. I bet closer to 3 on a stockish gt.

for a stock GT I think it's a waste. But this intake and some of the other aluminum intakes coming out have one huge advantage in a modded car..

they can be ported.
 
The best thing about it is.... If you have an aftermarket shaker for your GT... you finaly have an intake option...

But I'm waiting for the other 2 to come out before I buy some non US made stuff.

I am getting it beacause i want to cheap manifold that will withstand nitrous, and not have to worry about puddling
So spend what you save on not buying that overpiced intake on a dry shot kit and you'll never have to worry about fuel puddling or nitrous backfires. :)

how is it better than a bullitt? and if not, then how much is a substandard manifold worth?

I dont think it is better than the bullit but it shure looks cheaper. just the manifold is the price of a bullit and it works with your stock alt, throttle cables, factor intake ducting, etc.

this is definaltly not somethign that is nesseary for a stock car but if you had at leas cams it seems a cheaper alternative than the other options and seems to raise the power band right where you need to be for some of the 2v cams.

I cant see justifing this pare with out at least cams. I bet the gains of it over just a plenum and tb on a stock car would be very minimal just cause you don't rev a stock car high enough.

nope instead youll burn a piston lol.. but if nitrous was my reason for getting the intake I would just spend that money on a direct port system.. no worries then.

only if your a assclown and run a 100+ shot dry kit on the stock injectors. One of my friends just did that to his LS-1 :lol:

a well setup dry system with proper injectors and supporting fuel system mods is a safer nitrous setup than a dry kit.

you are calling both kits dry kits in this post.

No, then you just have to worry about going lean and blowing the ENGINE, not just the intake. Anyways, the P51 intake is like $1200 and it gives you maybe 10? Wow. I would rather pay $600 and get 8-10 w/ plenum and throttle body.

If you don't want to run it lean, don't get greedy. If you're going to start running a healthy dose of gas, then make sure you've got the fuel system to back it! The only way you're going to blow something up with a dry kit, is because you were being reckless (see stupid) with the giggle gas.

….and if the P51 is making 10hp on a stock car, then this POS P/P intake is making about 3hp…if any at all. You keep forgetting that this thing made a best of 25hp with a fully built engine with ported heads, cams and all of the intake and exhaust bolt-ons. P51’s have been responsible for as much as 30-50hp on an engine with the same amount of work. No intake is going to perform well on a stock car. Truth be told, the stock PI composite piece is already up to the task.

not only that, it wasnt JUST the manifold. It was PP Manifiold + 75mm TB/Plenum all together over the stock manifold, TB/Plenum. This thing wont make 5hp on a stock or bolt-on GT. Put the stock TB/Plenum on this manifold and watch the numbers drop. Like GB said, the stock manifold is up to the task. The only other reason I would buy this thing is if I wanted to be super safe while running boost or Nos.

WOW, the old mechanics tales are hard to kick sometimes.

WITH PROPER FUEL SYSTEM MODS <---- that is key.

People don't setup a dry kit right and then bash dry kits. 9-10 engine failures are due to stupidity, running untuned,stock injectors, not using the right plugs, RUNNING 87 octane on a 125 shot.

plus where do you think all that plastic goes when you have a nice little nitrous backfire, or how about the ones that burned to the ground. Had this happen to a friend of mine. his nice new Z28 went up in a fireball after a nitrous backfire.

direct port is the best hands down. then after that pick your poison with dry and wet kits.

ok perfect example happend just a few weeks ago.

freind of mine with a 99 Z28 installed a dry NOS kit, he also installed 36 pound injectors and then went and beat on it. he got up to a 100 shot and blew it up. I spoke to a mutual friend who was there. he ran it get this EDIT earlier i thought he had the stock injectors a mutual friend called me and told me he had 36 pounders but never had the car tuned, not even a canned tune for the injectors

1. never swaped to colder plugs.

2. never had the car programmed for the 36 pound injectors.

3. the system was jerry rigged and installed for free by a person who once tryed to use a electric cooling fan motor to power a turbocharger somebody gave him. let me make this clear. he tryed to install a real garret turbo from a buick GN in his intake tube of his cherokee and power the turbo with a fan motor.

when you have people like that install your nitrous is it a surprise it blew up. now if he paid somebody knowledgble to do the work he would have been told to get colder plugs and the car would have been tuned properly.

Sounds like your friend was going for a Super Turbonator :D
