According to the SVX FAQ page, cone filters in the engine bay are not advisable: SVX FAQ - Air Filters

UNLESS you build an airbox or separator for it there was a pic somewhere in the lockers that somebody had done to keep it drawing from the fender and not the engine bay.

If your intake resonator is not currently connected, removing it can't possible have any performance effect whatsoever.

Unless you count it as "weight reduction"- about 2 lbs, right Chike?

Correct.

2.5lbs on my digital kitchen scale for all of the hardware including every last bolt and nut!

I have an intake from my old del sol that i could mount it in place of the resinator then conect it to the top of the filter so it sucks in air from the fender. Good idea or bad idea?

Rob:

You said you use a cone filter, right? The way these are usually installed is that the airbox is removed and the cone filter is put in its place. The air is drawn through the cone filter from the air in the engine bay. That would leave the intake resonator disconnected as well.

There are mixed opinions on this setup. Some people swear the cone filter increases HP. Others say the air in the engine bay is warmer than the air in the fender, so the engine is now pulling in hotter air for a net HP loss.

If you are a believer in cone filters, the alternative is to extend the piping between the filter and the engine (using PVC, metal tubing, etc. etc.) so that the cone filter is located in a cooler location, like inside the fender.

The problem with this setup is that if the cone filter is located in the fender, it will be difficult to access. This will likely lead to poor maintenance (it may not get cleaned/ changed as frequently as needed). If this happens, it will definitely lead to performance problems (or worse). Additionally, if the piping penetration of the fender liner is not sealed, you will still have some hot engine bay air getting into the fender, and you will not have as good air draw as the factory setup, because of the pressure differences.

When extending the piping to locate the cone in the fender, if you eliminate the intake chamber (the plastic bulge in the piping at the back of the engine between the throttle body and the firewall), most people agree that you will have a net HP loss.

My racer SVX uses a stock airbox with a drop in K&N filter.The intake resonator is removed and the piping is extended down to a funnel shaped ram air box cut throught the bottom of the fender liner. I believe this give me good filtration and an increase in cool airflow at the same time.

Hope this is helpful.

I'm not dropping the filter down into the fender. The filter is staying in the engine bay with a sheild on it and there is a pipe running from the fender into the engine bay through the resonater port that has a rubber peice that can fit into the top of the filter. Air is sucked in from the surrounding cone, but most of it is from the top. I'll try to put some pics up tomorrow to explain it better. Thanks for the advice because turning it into a cold air intake was also an option.

I never did a factual measurement. (dyno, drag time, etc.)

It "feels" a lot better. That doesn't mean that much!

I just tried something to seal the gap between the fenter and the airbox when the intake resonator is removed.

I took a piece of hose and slit it down the side. I cut it to the proper length to correctly fit around the hole in the fender. The hose I used is thick enough that when I put the airbox back on that it seals the gap perfectly.

Can anyone on this site send me a junk resonator piece that they no longer have any use for? I need to install it with a stock SVX intake air filter for testing. Thanks!

BTW: I can pay for the shipping, no problem. I'd like it overnighted to me.
