WRX 2003 GT35R Plus Kit Upgrade - Seeking 800hp - 'The Monster'

This was a Youth Group Project, headed by Wayne Mumford. Xcceleration provided the highly modified engine and most of the upgrades, along with technical support. Wayne provided love, guidance and funds for the group project. The boys in the Group range in age from 14 years to18 years old and they learned alot about Subaru and to have patience when building. This experience will last them a live time. Special thanks goes to the best Subaru tech Wayne knows and his good friend Clay Ledbetter.

This project took almost one year to complete, with the attention to detail being AWESOME!

Justin, Carl, Jacob, Robbie,

Michelle, Jered, Josh

and Wayne (Center)

Josh was at work, we will try to get him in some pictures later.

 

Wayne called and said his unofficial 1/8 mile top speed is 120mph.

He also said he roasted the Exedy Twin Plate Clutch that day, clutch below.

We're now out looking for a stronger clutch....maybe a Triple Plate?

New Triple Plate Clutch

Now we'll see what happens!
