Intake ideas?

[onehalfasia]

I'll be making a 2.5in exhaust and need ideas for a powerful intake setup. Its a stock BG with advanced timing. Here are some ideas:

Custom Ram Fatty- Get a K&N drop in filter, mount it in a box towards the front of the car(replaces the headlight, or mounted in the bumper)...direct the clean air into the vaf, and then 3in or so piping into the manifold

Stock Ram Fatty- Use the stock air box and piping with K&N drop in, and route pressurized air with fatties into the stock box.

Out of the two, what would work better with the new exhaust, or what would you use? Intake and exhaust advice is helpful. For the exhaust I'm going full 2.5in mandrel bent from the manifold back, and a glass pack muffler (cherry bombudesu). Thanks for your ideas. Feel free to post your setups too, and how you like them.

Umm....velocity stack FTW!

poweful intake setup= leaft blower

i'm sry i know i'm useless

The velocity stack is basically what I linked you to earlier, it would reverse the negative air pressure (vacuum) that it has inside the engine compartment and turn it into positive pressure (boost) at high speeds. Velocity stacks are a tapered tube that causes air to speed up as it travels through. It allows more air to enter the beginning (widest part of the taper) then the air is forced back into the narrower part of the tube, increasing its velocity and adding more boost. Boost is relative here, it's not like a turbocharger but if you're going fast enough it should net a few HP. The bumper, like I told you earlier, has the most air pressure on it (it's the most protruding point) as the car is moving, so ideally you would put a velocity stack fluch with the bumper, it would then taper a few inches behind the front of the bumper, and run to a tube that goes to your air filter, which would be enclosed. This would probably require you to move the VAF so you can point the tube towards the bumper, and that might make it necessary to relocate the battery so you would have room to do so. Wal mart has battery enclosures for pretty cheap, you could mount the batter in your trunk, just make sure to re-ground your motor, ground the battery to the trunk, and run the + alternator wire back to the battery, and basically keep it wired like it was before. 4 guage should be enough, and consider wiring a few fuses throughout the system to avoid an electrical fire, which probably wouldn't happen. Once the battery was out of the way, you'd have significantly more room to experiment with an intake system, and it would help your weight balance a bit and generally make the engine bay less cluttered. Sorry I didn't tell you all of this on aim, I had to think about it for a bit plus I was doing other stuff.

he hit the nail on the head!

the problem with the stock airbox is the really tight radious narrow bend that goes to the VAF, now if you can reshape that alittle to serve the same purpose as a velocity stack that would be the biggest gain IMHO.

all i did was i bought a 90-93 accord short ram intake, then cut it in 1/2, then i made the VAF sit facing towards the front of the car, then i dropped the other 1/2 of the intake downwards. its a freaking awesome set up. i had it all facing where the stock one went before and i bogged bad. now its sooo freaking loud and peppy, and you dont have to worry about it getting hot:) because you have your rad fan blowing right on it ;)

If you plan on using a bigger AFM(the RX-7 AFM or a hybrid) you won't be able to use the stock airbox.

Pics? :rant:

But doesn't the radiator fan draw air through the radiator, hot air, from the hot radiator that's being used to keep the car from being hot?

It definately does, and i bet the air in front of the radiator fan will be warmer than the air outside when the engine as at temp.
