Should not effect your F/I at all...if anything, it will help becasue it will flow better.

IMHO, these intakes are eye candy with maby a few hp gain on our engines. For these intakes to shine in n/a we would have to rev our engines way past 7k, even then I would much rather have individual throttle bodies with short runners. As for the price, still seems steep considering its basicaly a big old plastic piece. $300-400 is tops I would ever pay for that. Even with Fi, I would rather not have a intake manifold at all and go with a edelbrock SC.
Out of curiosity, how fast have some of you guys reved these engines? The shop I recently visited and talked about going high rpm n/a said the 4.6L 3v has oiling issues with high rpm. Witch seems to be supported theory as most short blocks come with a ford racing high capacity oil pump to try to remedy the issue.

I think that was the hope with the majority of the people that spent the $$$ on heads, cams, intake and were still shy of 400hp. I don't know that I've seen one person (without a stroker or bottle) that can claim 400 or more on a N/A. It would be nice though...

I rev @6500 with stock everything except tune. Ive seen some guys do 7k with stock internals. But from what I gathered was that even with forged parts and a valvetrain that can handle the stress the oiling system is unable to keep up with demands for much higher rpm leading to starvation problems. I am unsure if it has anything to do with the variable valve timing or actually the design of the engine not supporting much higher rpm.

There has been some study done on the previous 99-04 GT motors that indicate that the rods stop snapping back into shape around 6800 rpm. We're talking consistent rpm where that would manifest into a problem however.
6500rpm on the stock mill (parts wise) isn't a problem. The VCT does suck up quite a bit of oil however, and so again sustained high engine rpm can cause a problem.
Adding half a quart or a full quart to the pan if you know you're going to be on track may help with oil starvation slightly. It seems however that the oil pump simply isn't up to the task however.
One thing to keep in mind though is that this shouldn't present much of an issue unless you are the type of driver that spends the life of the engine at, near or past the effective rev limit of the engine. For those of us that drive our cars and only occasionally shoot up to red line then right back down to speed, this isn't going to be inherently a huge issue. Over time it may limit the total effective mileage the engine will run, but we're talking 180k instead of 200k with good service intervals.
The 3v is the last iteration of the modular family and it's also the best in terms of volumetric efficiency and synergy of working parts. No it doesn't have all the forged goodies, but where mistakes were made in the past, they've been corrected. It's a testament to people running around with 500rwhp out of the stock components. Things like upgraded bearings, main cap design and importantly piston wrist pins, which tended to be the 99-04GT crutch.
I'm getting long winded here, but basically unless you're driving the car on track all the time where rpm's may never drop below 4000rpm, you're not going to have an oiling issue so long as the car is maintained properly.

Structurally the engine is pretty close to that of the 98-01 Cobra motors. The parts can take up about 7000rpm pretty easily. The pistons and rods are pretty light which help facilitate that.

Thanks for the info. What I was planing actually is a forged rotating assembly and balanced as well. Then some high lift cams & a redline between 8.5k -9k, providing they make springs that can still be considered reliable after taking that type of punishment. Toping it all off with ported heads and short runner ITB's. Obviously I would eliminate vct & install the "upgraded" oil pump. I am somehow sure that this would not survive long. Projecting around 500crank or more with 11:1 or better compression. Would love to be able to tune that setup for 93octane and go raping. Obviously the exhaust would have to be fairly free flowing with long tube headers & possibly no cats.

Your just full of info ain't ya? Maybe you would care to break down how it would need 50k worth of work?
Expensive yes, more costly than FI? Possibly. But 50k worth, strongly doubt it. maybe in the 15k range, its entirely possible. In any case, what is it to you what I spend on an engine?
In any case, I see this type of post as spam. And it seems like 90% of your posts are geared that way.

that's not spam. I would've said the same thing! You can get an engine built for less than 15K, stroke it for less than 5K, or FI for around that on a brand new setup or used for 3-4.5K. At the end of the day, you will pour out a ton of cash, and someone with a supercharger might just be showing you his plate for a 1/3 of what you spent. Would you still think it's worth spending that much? I wouldn't...
It's nobody's business how much cash you want to burn on a project like that, but just like you want to write on this forum what you want to do with that, we can write on this forum that we think you are nuts. It's not spam, it's freedom of speech.

I agree with what you say, however there are always two sides to the picture. And he is just that, a person that thinks his route is the best route. Sorry dude, the world is not built the way you want it to, and at the end of the day comments that truly do not add to a discussion are spam, or useless.

edit:
And I just re-read and saw that you want individual throttle bodies too. Throw the check book out the window because you're going to need a ton custom fab work for that. 50k was probably too conservative.

11:1 cr is quite possible on pump gas. Some engine builders have built engines with higher compression and still run on pump gas.
Oiling is what I was mearly asking about. Then again a dry sump system for mod motors can be had for about 2500bux with pumps. As for any oiling issues after that, gotta pay to play.
9,000 rpm is well within the specs of a good forged set of pistons & rods.
ITB's are arund 3k.
Now as for fuel system, a full return style fuel system can be had for less than 2k with triple pumps in the basket.
Now about that 50k?
My point being is that you do spam. You post & try to look smug about it. If you must even waste your time repplying to a jack *** like me. Might as well throw in some good info, the whole reason this is called a forum and not a jack *** fest is because people sare thier information and opinions. However you seem angry at the world & the only thing that satisfies you is posting single line repplies and acting like your the end all be all.
Im done. Thanks!
