flipped engine mounts....
unhooked the dogbone mount from the core support.. get 2 long screw drivers and some WD-40 or your lube of preference..if you look at the mount its solid up and down.. put a screw driver on each side, spray WD40 all over the rubber(dont be shy with it) and spin the mount so its solid horizontally.. this is basically a offbrand solid mount.. will take away half if not more of your engine rock. good for people who have problems with dp rubbing on sway bar or people who wanna break them loose 10mph faster then what they already do lol....

MAF Descreen... please put it back in.
a. it helps channel the air in right direction
b. it helps to keep any debris that may get passed your air cleaner out of your supercharger and engine.

yes BUT it slows the flow of air by 10 to 15% in the process, (aka slower air means hotter air) as tested by ZZP , which i trust considering they hold the world record for fastest fwd 3800 with a 9 sec 1/4. and ive done it now for a while with no ill effects so idk....

But, without the screen you get a very turbulent flow into the intake. The screen is in there to create a more laminar flow. You will see that the screen is built in to the LT1/LS1/LQ4 MAF sensors, and for a good reason. I would leave it in.

my LT1 didnt have one.........but my LQ4 does

leave the screen in, it is there for a reason. you will really notice the difference at idle.

I had mine out for the longest time and after reading some of the debates, I decided to put it back in and it did seem to make a difference in the idle.
That said, Ive read from some that it helps with tuning as well as the MAF reads better.
01-07-2008
yea i know about the idel thing but wot sposedly it helps, do u mean the maf reads better with it in or out?
01-07-2008
the debate thickens… I had mine out and two MAFs died. It got killed when I pulled it out, so I don't have it to put back in (though I probably would if I had it).
How about removing that rubber weather strip at the base of the cowl?
01-07-2008
You mean the thing that runs along the back edge of the engine bay and keeps the hood from rubbing?
01-07-2008
I assume so. Mine was off for a looooooong time and I never had any adverse effects from it. Seems like it'd trap in a lot of heat.
01-07-2008
i take them off every grand prix with its hood open lol
its like a free cowl effect, and you can actually see the heat coming out on a cool day. i also have 2 washers between my hood and hood hinge.
