Green Hulk's supercharged FZR build up

[Green Hulk]

Glad you enjoyed the thread guys!

Can't wait for the movie!!

Did you get any measurable performance with a Waterbox? I'm looking at one now.

Yes, most people get 80-100 RPM gains with a waterbox not to mention the sound is way better. This Riva waterbox is the way to go. Don't forget using the coupon code greenhulk in the forums store will save you 10% off the listed price http://www.4-tecperformance.com/inde...oducts_id=1491

Will do, I have mostly RIVA everything thanks to your incessant nagging. How will it help on the drone of my Riva FF exhaust on my FX SHO?

[Green Hulk]

Free flow exhaust has a terrible drone. Waterbox will just make it worse. Best solution is rear exhaust. No drone and sounds 100x better.

Hmmmmmm, I'd love a through hull but I lack the funds at the moment and I already have a Free Flow. I can't see spending that much cash for zero performance gain. Looks like I'm stuck with the drone.

For those wondering why a Turbo makes so much power on less boost; efficiency. A supercharger simply climbs in boost with RPM's while a turbo will spool up to a target boost range, say 15PSI, and hold it from spool, on these 1.8 engines you can EASILY have 15PSI by 4000-4500 RPMS and then it holds 15 PSI to the 8000+ RPM's, a Super charger cannot do that, it has to climb it's boost in lock step with the RPM's. The power under the curve is increased dramatically. Turbo's rule.

while you are spooling up with your turbo the SC boat will be at the finish line

How long is the race, ten feet? Maybe, you have to understand that it isn't RPM's that spool a turbo, it's load. The more load on an engine the faster the turbo spools. Go rev a turbo car in neutral, you'll struggle to make any boost.

I dont believe I saw any pics showing off the whole ski. Lets see the whole thing. I like the mods/ideas that you have done so far. Wish I could do something like the air ventalation, but I ride in some heavy surf at times.

Check out the first post on this thread.

Here's a pic of the whole ski the day i got it home

How did you rig the red handle Valve on your gas container hoses ? Is that a 3/4 inch PVC valve ?
Please advise - I am tired of people spilling gas on my ski

Sorry I am just seeing your post. Yes they are just regular PVC ball valves.

Great info here on how to do things the right way. As a newb to watercraft, this site is a real blessing.

wow that was a long read. can you expect similar numbers out of an 09 sho with the same mods? Thanks for the inspiration Jerry

Removing cowling foam.

The cowlings come off very easily. You must remove them to get the foam pieces out.

Hey Guys,

Can anyone walk me through how exactly to take the cowlings off? I don't want to break anything. Does the whole side panel of the ski come off first, or just the black cowling? didn't see any accessible bolts in there.. After reading though 67 pages of this thread, I gave up. Any help would be great

Thanks ,
