I performed the air box mod on my Olds LSS - supercharged over the weekend and was impressed with both the SOP improvement and sound.

You can sure tell the car has a blower now. Its not Cobra loud, but when you get into the boost it wurls nicely.

Can't wait for the 3.4" pulley

Thanks everyone on here for the info and pics. I use a dremel tool and it took about half an hour. Great free mod in my opinion.

get an intake on that thing and here it scream

The LSS seems to respond to everything. That includes K&N drop in filter and 30* temps. This somehow brought my 0-60 from 6.9 sec. down to 6.6 sec. The 6.9 was taken with an old nasty filter and 85* temps.

Just remember, when you get that 3.4" pulley, you are gonna want more than just a gutted airbox.

i have a 2001 sle, i dont know anything about pulleys but can i get that for my car or does it have to be supercharged?

tony

Sorry, has to be supercharged.

you could always put underdrive pulleys on and free up some HP

Do they make an UDP kit for the 3800 series II?

yea there is one for the WP and the Alt.

Once you get the 3.4 on there it will whine a LOT more, not only that, but the car will pull a lot better too. Better get a couple other mods on that thing first though.
