    951 DI what can I do to improve performance

    As the title says I am working on a 951 DI in a GTX the guy wants it to go a bit faster. What can be done to these motors impeller etc to help. I had really good luck with Bens secret mods on my carbed 951 so I know there are some really knowledgeable people on here.

    Check out the PPG link that Airbornexp posted. That is what they do as part of their Level 1 kit. Be prepared to break out your wallet though. $949.00 +ship and to run high octane.

    Bolt on .5 to 1.5 more top end plus stronger midrange and less cavitation on take off. All without touching the motor.
