Performance Kit . . . Designed by WBBrian
Topic: WBBrian came up with a performance package that consisted of the following:
- Aluminum Velocity Stacks
- Modified Exhaust Diffuser
- Tall Exhaust Can
- Powervalve - welded to end of exhaust pipe
- Speed Plug - Fiberglass
- Scoop - either a modified Super Scoop or Pro Scoop
- Thru-Hull Exhaust
Details are found here - Velocity Stacks
And here are a couple of the pics:
Details are found here - Exhaust Diffuser Mod
And a pic showing what the modification consists of . . .
If you already had a tall can, this modification is not necessary. If you have the short 50hp stack, or the intermediate-length stack, then this modification is necessary if you do the Exhaust Diffuser Mod.

Here's a couple of pics of an Ultra Scoop and Pro Scoop
This is an idea Brian came up with that combined a powervalve and a thru-hull fitting. Worked great but I believe he said "it's so loud you can't hear yourself think". I also remember him saying that it didn't add much noticeable improvement in power over powervalve in the exhaust pipe. Meaning . . . the single exhaust baffle in the pump was not robbing any power.
