On both the 3800 series 1 and 2 there is a "screen" in the throttle body which I belive is for smoothing out the airfow into the TB. Has any one removed this? Compairing before and after differences in power and MPG?

I removed mine by the advice from ppl from Bonnevilleforum.com and noticed no differance. I lleft it on the bench for a couple days and it ended up broke. so it is still out but no noticable differance in performance.
BTW mine is a series 1sc

I've played with them and leave them in. Some masses don't like the turbulence. My S1 and my TR like the smoothing. My S2 didn't seem to care. I also leave them there to avoid a bonehead mistake that sends some large object into the engine.

It looks to me that the turbulance is due to the factory induction tube(ser 1) from the air box which does not have a smooth inside surface, it is "rippled" for the bend to be flexable. I intend not to use this tube.

I used a crx intake on mine. So either way you take it or leave it I dont think you will notice a differance either way.

jb1: When you mention a crx intake, should I assume an aftermarket tube that would normally go to a Honda CRX? If so what years?
Thanks.
Now I just need some warm weather to start on this.

I wrapped mine with heat insulation tape from DEI to help keep it from getting really hot from the exhaust crossover pipe, The chrome looks better Ill probably buy another and leave it chrome to put on if and when I ever talk it to shows.
