My ****'s a DD. What's wrong with wanting civility coupled with performance?

Last time you were on track, there were separate lanes for whites and coloureds.

What i should really say is the guy on m.net who think it's "omg so loud that everyone hears me coming and it screams I am doing something illegal!!11!!1"....the intake isn't all that loud outside the car, you can't hear it 50ft away unless you're at full-tilt over 5k rpms. It's simply not al lthat loud even when goosing it at mid-rpms or from a stop light.

My BOV on the other hand....get's looks from 100+ft away

I found that when i fitted a obscenely larger filter, the intake noise went down dramaticaly. I did have to french my hood to accomadate the 400+cfm static flow filter though.

turbulence is noisy ... hence why large filters, large diameters, and horn flares reduce the suck noise.

As for the turbo hiss, Keith @FM has posted about home depot foam around the filter to quiet it down.

You can make a cool air box out of coroplast. It wont melt. I swear. Free material (election sign) and easy to work with (scissors). It is a win win.

What's coroplast?

I used to be of the same opinion re intake noise, and have ribbed other members on it, but I'm older now and the noise has gotton old and annoying now.

I don't use mine on my turbo.. lol. Umm, coroplast is the plastic cardboard from election signs. Useful at making Ducting and RC planes.
