08 RXT-X mods opinions
Yes I searched before posting this and got some background knowledge. I'm different than most I think since I'm almost strictly a bay boat with some ocean trips, not a flat water queen. I routinely take long rides so I'd like to not kill my efficiency. Most of my driving is just cruising from location to location.
I have an 08 RXT-X with 68 hours on it currently. (Example of what I mean - I put 8 hours on it this weekend).
It's stock right now but am curious your opinions for mods given my constraints.
Seems like the R&D X grate would be the best for me?
fill ride plate holes
Riva free flow exhaust (probably not thru hull)
I'll probably see 71-72 out of those mods and they'd be the basis for anything else I do so I could grow into them.
Those are definite mods unless anyone has better suggestions. The next set is more theoretical.
My friend is selling a 137 wheel. Thinking of possibly picking that up along with an ECU valvetrain mod, and rrfpr so that I could make the most of the 137 wheel.
What would I see out of that and/or what would I need to support they?
Or any other suggestions for mild yet effective setups?

Oh yeah, and ask Scott how to remove that intake screen in your manifold
A wedge would help too

Anyone else have opinions?
Sounds like I'll be rebuilding the charger at the end of the year, probably putting in the 137 wheel. As well as grate (still waiting for people to weigh in on which one), intake, fill plate holes, maybe exhaust. Oh, and prop...15/22R maybe?
I can get by on the stock ECU or injectors with that wheel?
That'd be great, to do all that, keep stock ECU, then maybe end of next year do valvetrain kit + ECU so I can make better use of these mods.
How are flow rites for water ingestion?

Keep it simple and maintain your fuel range - 4" Air, R&D grate ride plate holes 72 to 73 and you can still ride all weekend without worries.

et 137 with supporting mods (stock ecu) should be around 74-77 mph on the stock plate with supporting mods. MAKE SURE YOU DO THE TUNNEL!!!!

Second, remove the supercharger, add the Viton front seal, check the slip on the clutches, and clean the Intercooler of oil residue.
Third, free mods: remove the flame arrestor, trim the reverse bucket, fill ride plate holes.
Forth, install an R&D intake grate or the Worx intake grate
Last.....Solas 15/22 impeller....send it directly to Erik at SpeedFreeksRacing for re-pitch and setback mod.
If you're not interested in top speeds like the rest of US flat water queens then you're Done.....and enjoy.

I was involved in a radar run with a boat racing club Sunday which made me more interested.
Worx vs. R&D grate?
Also would like opinions on better intercooler for long rides/mods as well as a BOV

The stock intercooler is very good......but its efficiency can be improved by separating the incoming waterline which T's off to the exhaust manifold and IC and downstream T's again to go out.
The prevailing wisdom here is to NOT use a BOV......
