Stopped by the shop today to get an update on the progress of the intake. Main guy was not there so I talked to another guy to get some feedback. He called the main guy on the phone (who was on the road) and got back with me.
He indicated that it 'seems' that having two tubes coming from the throttle body is 'almost' an impossibility due to the amount of room needed for both intake tubes to occupy. This was based on the measurements that were taken. He told me that the main guy was working on a modified version of the dual throttled opening box of sorts that would be similar to the stock intake. I told him that would not be acceptable. I want dual intake tubes coming from each throttle body that would join further down the intake path towards the air flow sensor. If they can not come up with a solution, I will scrounge up something myself to testing. They have the flexibility to use stainless steel, silicone tubing with bends and/or aluminum if they must. Even plastic bends is acceptable. I just want two tubes merging to one. The tubes can be no less than 1.5" each. I looked around their shop and have a couple of ideas if they do not move on this. They are pretty busy and have other priorities but I don't want to wait months for something that can come together in a matter of a couple of weeks. I'll give it to Monday before making any moves myself. With the piping/silicone hoses and such they have, it can be done. So this is where I am at for now.

Does anyone know who I can talk to about making this piece up for me? The shop I stopped at is still scratching their heads. Thanks!

Kevin,
Find a local shop that does roll cage fabrication. What you've got in the picture is fairly basic roll cage fabrication work.... If you can't find a "cage" fabricator, try finding a shop that does custom headers.... -Bill

I know of such a shop. Actually, Xotic Motorsports (Where I get my dyno runs done at) has a older gentleman there by the name of 'Art' who has partial ownership of the shop. He does the welding work there. I'll hit him up to see what he says. Thanks!

im not exactly sure why people are thinking that the intake plenum is restrictive. I do know that having 2 pipes that are not designed correctly could cause a bias. This is of no concern to sam as its obviously pressurized. I dont see you doing anything but loosing horsepower with an engine that pulls a VE of 98% stock.

You have a valid point. Are you willing to put $$$ on my losing power with any intake design that I make up? My Paypal is thomasck@comcast.net. I am sure you are right but I am a curious person and have to test these things out. $5.00 bet! Lets keep it simple.

After reading this thread I have one thing to say.
Your stock intake is not restrictive. Everyone can throw around ideas that may seem usfull but the engineers did it right the 1st time around. The MAF is set in the position it should stay in and everything behind it should not change. Also, Phil. My money is on you. What size SS tubing did u use? Tom |

unless you are throwing a turbo or supercharger in there, there isn't much to be gained (possibly even a loss with some crazy design). keep a clean filter in the stock box, and divert the brainstorming elsewhere....

FYI folks, as most of you would know, the SVX has the same sized airbox as the STI and WRX. I asked a few tuners over on nasioc and clubwrx about the power level you would need to reach before the stock airbox becomes a restriction - I was told 300+whp!

sounds right to me....
Shifting from the usual "more is better" state of mind to what intake will allow us to flow and keep and resonance through out the band is required when working with our engine. It is extremely efficent, and meticulously worked through. I don't need a dyno plot to tell me you arent going to improve on a 98% VE engine without loosing power someewhere else by modifying the intake. phil

Keep up the good work Kevin, someone has to do the pioneering work "restriction" or not. Someone has to change and experiment on their own car, no matter how much others say its not neccesary, in the 3 years I have been a member here, people went from being negative about the 5-spd, and saying the 4.11/4.44 swap was impractical or impossible to them being well used and commonplace, and not to mention the great work that LAN has done with the ECU and MAF. I needn't even mention what people previously thought was possible with superchargers/turbo setups...so just keep going!! 'Sides you can always return it to stock if you have to!!
