Aftermarket Intake Horsepower Guess Poll

[Myxalplyx]

I just wanted to get a head count on opinions on how much horsepower a fully custom made intake could yield on an SVX with the exhaust already done. When I say exhaust, I mean with a custom made exhaust from the exhaust port back. Pick the exhaust configuration that you think is perfect for the SVX. Once this is installed, how much hp do you think a custom (Meaning that all the piping before the throttle body has been modified) can make. It does not matter what the intake setup is (for those that don't think it matters), just assume with the best made intake possible (besides the stock one).

1) Less than the stock intake,

2) 1 - 5hp,

3) 5 - 10hp,

4) 10hp +

You and your intakes

Is this poll for the intake AND exhaust hp gains compared to stock, or is it the intake gains after custom exhaust. If its the first, ill say 5-10, if it's the second...1-5. Numbers id put my money on are 10 and 2

now...remembeing that chike's car has had the cams, and presumebly fuel pump, injectors, and an ecu chip done...an intake and exhaust could possibly yeild more on his engine that a stock one, due to the increased time the valves are open, ect. But once again, I dont think the intake and exhaust are overly restrictive

When you say no paricular exhaust configuration, please specify weather the car will be street legal or not...Seems to me straight pipes with MABEY a muffler would be "the best", but it'd probly have a hard time passing inspection

After custom exhaust....any exhaust...of your choice that you think is best fitted for the SVX.

And thanks for your responses so far.

Street legal!!

i think you will loose power with any intake setup other than maybe a true ram air setup if you were to create it.

How can an unrestricted straight piped intake make you LOSE power over a curvy thin plastic box contraption?

Figured I put my 2 cents in and say 10+hp. This is only based on previous dyno's with other subarus of mine with aftermarket vs stock intake. Yes, they are different models but still.

I am looking for a stock resonater to install with the stock intake and will be purchasing a new stock air filter for testing (Currently an STI air filter is installed).
