And how was I wrong? For carb setups, I may be, I'm not familiar with them. I was totally thinking fuel injection setups when I posted just because that's all I know of personally. But you even stated that you can't just put a filter on the TB and make power. That it will lose power over a good intake due to turbulence and so on. That was pretty much my point. Some other posters basically stated that an intake just frees up hp, and I was trying to explain that they can make power through proper design.

Same with the exhausts. If we subscribe to the theory that they just free up power, then there would be no point to design. Just take it all off, I was trying to refute that point. I just didn't do it as elegantly as you did, so maybe I wasn't clear. You are 100% right in your answer. But my post didn't really disagree with anything you said.

Anyways, people, just read what Quicksilver said. It should make things more clear

You were basically right...but SXN and I were just post whoreing

The design stage is the most important part of anything that will produce or free up HP in our cars.

post whoring AND making fun of you. our car is really touchy, along with most modern cars. A lot of tunning is needed. especially because of the little things, ecus, knock sensor, exhaust/intake sensors, etc

I really don't worry about n/a power, so intake design and so on is a moot point to me. I was just trying to answer a question. I prefer boost, so that's my method for adding power(and that is definitely a power adder, to keep this on topic). Trying to free up or add 2-3 hp through better design is just fruitless to me when there are other options.

And if you really feel the need to make fun of me, well, have a good time I guess.

well in some cases, no FI mods can be enough. for example the order 5.0 mustang. they had horrible intake and exhausts. with new headers and exhaust, you can get almost a full second in the 1/4 mile. cold/ram air gave a lot of gains too...its ridiculous

Yes, but the mods that help N/A cars are even more of a positive difference on boosted cars like yours (or like yours will be...was...whatever). Take for example porting the heads, doing valve work, and massaging your combustion chambers...
This does wonders for N/A vehicles (I could see 15-20 WHP in a N/A VQ35DE). But in a boosted engine, that number could easily be 30-45 WHP for the same exact thing...maybe more! It just depends on whether you want to extract every available ounce of energy from your combustion process...

FI is a tricky topic in itself. forcing boost down the throat of your engine CAN make power (lots of it)...is it worth it? usually yes. but the functionality, and daily usage of my maxima is still important. im not building an all out race car

Oops, I guess I was vague again.

I definitely plan to do things other than the boost that will hopefully improve flow/combustion and all that. After I get the boost setup complete, I'm working on all the peripheral stuff, intake manifold, exhaust stuff, and so on. My friend is a good fabricator, so we're going to try some other stuff that may work better or maybe not than what we have commonly available now.

And my car was boosted and I'm almost done getting it boosted again, hopefully by the middle of next week all of the basic fab work will be finished and the car will run.

Boost definitely does have it's problems and takes some getting used to. If all someone is looking for is a little kick, then boost definitely isn't worth it. But if someone is going for a lot of power, then often times boost is a better solution than all motor. At higher levels of power, a boosted car is probably more livable than an all motor car due to fewer tradeoffs. But that's just my opinion, boosted cars can be made very unpleasant to drive too.

yea, an all motor engine is hardcore. hopped up b18 motors, have high compression, rev high to make its power, have horrible idles, etc. they can die quicker than boosted engines that make more power. then at the same time, boosting an engine can make it die just that much faster...low PSI is generaly fine, but i think you need a moderate combination. lower compression pistons with a low dish top, new valves or cams... THEN boost it. you want the engine to be built for the boost

That's exactly what I'm doing. My 8.5:1 pistons and Pauter rods are off getting Swain coated right now

I'll probably kill myself within the first month of being turboed...
