Underdrive pully
Dual 3" Cutouts
Free Mod on the Ram Air (Stock WS6 Ram air right now)

Car has 3.42s in rear and is M6.

I have a VRE 383 with LE3 Package. Pacesetter LTs, CSR Waterpump, Full ported Intake, 58mm tb, 1.6rr.

Just aiming to see what other simple little mods I can do to squeeze out some more ponies and maybe break the 440rwhp mark. :-)

 

No one?

 

The cutouts will do more than the others. Put a switch on yous ALT and turn it off just before ya stage. If ya got a fully charged bat and no headlights it will be fine.Then turn it back on down the return road.

Put a 4.11 in it and some real sticky tires. On the dyno AIR them UP UP to 32-35.

 

I wonder how much I could gain from the cutouts? Right now it's... Pacesetter LTs, Pacesetter Y, SLP Loudmouth Catback (LMII Muffler). 3" all the way

 

Also the cutout/s in the right spot is worth something as well.... right behind the y-pipe is a good spot since it's far enough away not to hurt the tuning of exhaust lengths.... but then again the f-body system isin't the most ideal in that arena.

To me tuining is worth the most to get every little last drop out of a motor. Lots of dyno time and just trying things is really worth it.

But what about the UD Pully and Ram Air setup?

 

I've seen a guy pick up 12 rwhp and 8 rwtq by removing the belt. So that shows there is power lost by the belt driven accessories. The pulley may only net you half that but if every bit counts go for it. As for the ram air mod you could remove the top piece on the dyno and see if it makes any difference or not.
