Throttle Body screen removal

[ryuhito]

I'm still a bit hesitant to start taking stuff apart. I disassemble my computer without a moments thought but I need my car running well on a daily basis. The plan is to either wait until I can get a step-by-step description of the process or get out the shop lights Tuesday night after I've been at the bar for a few hours.

you can find a easy description of the process on www.zzperformance.com - but I doubt it's going to be a scary job.

I have not done it yet for reasons stated in my last post, and my description is just what I remember from the ^^ website

the way I understand it - you just disconnect the "tube" going from the airbox to the engine's throttle body, and the screen is right there covering the hole on the throttle body. You need two screwdrivers to squeeze the clips which hold it in place, but that's it...re-connect the "tube" and you're off!

Removing the throttle body screen is a good idea if it does not throw a code. If you find after removal it has thrown a code, you should replace your f-duct (the rubbery accordian piece) with either a straight shot fenderwell intake or a piece of pvc pipe with clamps (ghetto style). This will insure that the air being sucked into the throttle body will remain straight. The stock f-duct piece tumbles the hell out of the air, mainly to reduce the supercharger\intake sucking sound noise.

The two manufacturers that build or built worked throttle bodies for the L36 and L67 both remove this screen to increase flow. Just be extra careful never to have the engine running with that throttle body entrance exposed. If a leaf or some kind of wrapper gets sucked in there say goodbye to your engine. If you have a proper filter assembly in place you should never have a problem with it and it will probably offer you an extra horsey or two if your running a smaller pulley.

If anyone is considering the zzp stage 2 throttle body and has a few mods on now that would make use of it, I'd go for it. I have one and they just rule. Increased performance throughout the rpms everywhere

When I removed the screen from my TB it was totally clean. The car is a '99 with 47K miles. With my 9" K&N and 3.4" pulley the car is noticeably faster. I guess I couldn't really feel a difference in power when I first removed the screen, before the pulley upgrade. I just want maximum flow so I'm gonna leave screen out.

I pulled the screen out of mine today. A 2001 GTP, 29000 miles. The screen was clean as clean could be. Boy what a difference! Nice clean shift's, and more power. Now the guys who said it's a little rough on the idle are right. It's a little rougher idle at a stand still in park or "D", but once you hit the gas she's smooth out. I used two of my wifes sewing pins to get the screen out, it worked very well and didn't damage the C ring or screen.

I have been told that the screen is there to reduce the turbulence of the air entering the PLenum. Turbulence is friction but applied to low density fluids. So if you take it out more turbulence thus less air speeding thru the TB, but, if you check http://www.zzperformance.com/zzp/fre...en_Removal.htm they say they made bench tests that showed at least 15% increase in flow so you be the judge. The only downside they mention is roghness on the idle, but, besides that nothing else.
I have not done it but reading the 2001GT testimonial what the heck would give it a try.
