R&D or Riva Performer Kit for SHO?
Looking at improving the performance of the SHO i have just purchased i do not want to tamper with the internals of the motor. I am looking at the R&D or River Performer kits. I Would like a non supplier opinion on the kits as which would be better both claim 68-70mph is this accurate as i have used parts from both supplies and there claims are not quite accurate in previous instances any help from someone who has had experiance or used the parts would be helpfull.

Manufacturers descriptions not accurate...prob has someting to do with them being written by their marketing depts. I don't think anyone has posted results on the R&D grate but I use the Riva and it works great. The R&D ride plate adds some speed & better handling but loses hookup in the chop. Riva has not released theirs yet. I got good results with the Riva filter but haven't seen much posted on R&D's. Some of us decided to stay away from it because we do a lot of offshore riding and where it mounts there might be more possibility of water ingestion. R&D's CFM kit will outperform Riva's manifold piece but needs a prop repitch to stay off the limiter. I'm guessing the exhaust pieces will perform about the same. I use the Riva sponsons and have mixed feelings on them. They make the boat more responsive but set full agressive are a bitch in the chop. A couple weeks back I was standing up watching someone do a speed run & hit some chop at ~50 and got launched. My advice is to use the search button & research each part individually from others experiences and pick the ones you feel will work best with your application. There's no need to pick one company and buy their package.
My speed results to date:
Stock - 67.0
+ Riva grate/R&D pump seal kt - 67.2 with better hookup & reduced cavitation
+ Rva intake - 68.4 with improved throttle response

Uh oh. I bought one of those too after several people told me they are a POS. If mine leaks boost like that I hope they will still take it back after 30 days.

BTW, did you install the cooling kit yourself? If so, how hard was it?

Sorry, football update, lol. Ya, that Surge Valve sucks yo. Needs an adjuster or somethin. Um, the Intercooler cooling system was installed by DP (aka The Wizard). He da man!! I wouldn't have a clue, haha

Thanks for the update. I already have the adaptor, so I'll have some results next week as well.
