Im thinking of ordering these the same time through Brenspeed. It says the underdrive pullys are good for 10HP. What are the delete plates good for? Are these hard to instal with basic tools or am I looking at a professional install?

 

You'll need to take of the intake plenum to install those delete plates.

Heres some instructions to show you how much work is envolved to install the UDP...

tacobill has a great write up about the plates.also i'm wondering the gain on the plates as well if anybody can infor me more about these delete plates i hear so much about.

 

u know how before u enter the 2005-2007 section it previews the most current topic. all i saw was "underdrive pulleys/delete..." for a minute there i thought someone was gonna attempt a UDP delete.

Hmm...thats proof enough for me. I think I'm going to look into getting a UDP and delete plates before the end of the summer. LT headers will probably wait till next winter or summer.

 

UDP 2-5 rwhp
Delete Plates 5-12 rwhp

UDP usually give more gains than the Dyno shows. They free up power from "spinning up" the accessories in much the same way you get gains from aluminum flywheels and driveshafts that are out of proportion to dyno results.

 

Delete plates > UDPs

 

UDP's > Delete plates

I'm quite happy with my UDPs.
