70 MPH today
well today after I installed the intercooler I hit 71 with 3/4 a tank of fuel at 8050 RPM`s the acceleration is awsome
my air/fuel reading was 12.6-12.7 WOT still with the stock injectors my boost was 9.2 at 8050 but my gauge has a short in it as it would work then not work I could wiggle the connection then it would read again, after riding about a hour my RPM`S went to 7950 I need to figure that one out as I have the RR thermo so I thought I would not have much heat fade but I was still running over 70. I would like to try a 4" intake and see what that will do but I am happy with the results so far it is cool to be running 70 on my couch
my mods are
RR motor mount
Riva thru hull
RR SC with 06 kit and metal washers
filled ride plate but not grate
Dynotune air/fuel and boost gauge both have problems

Sounds like the prop was just about perfect for your setup.

Nice!!! I think it's going to start getting cooler. I can't remember where I posted and if you replied but I might be hitting the water next thursday if you are going to be out cruising anywhere and want to meet up.
WOOHHHH just realized YOUR RUNNING THE RR SC WITH STOCK INJECTORS!!!
and it's working!!!
hmmm think the 4" might make you lean? guess one way to find out.
If you wanted you could pop my rear intake on without a seat and see what it does

I think I can make it Thursday Old Hickory? Percy P? or the River/
yea I would like to try the 4" and see what the gauge says and if it changes the boost numbers if I can get the gauge to work right

I'd like to scope out Piercy Priest. I haven't been out there on the ski and I'd like to go out there for labor day for the show.
I think I have your cell in a pm I'll call you on thursday, if it looks good. I can probably get out to the water at like 5pm maybe 3-4. work.....

Shhr, you need to raise your peak rpms a little more to get more speed out of that couch i bet that if you try a tweaked 14/17R pitched to run @ 8150 rpms @ WOT with your current set-up or tweak your 14/19.5 to gain at least 100 rpms more, you would find more speed, good luck

I always see 8050. SOMETIMES it might pop 8100 but it's because it's skipping or pulling hard.
I'm curious to see shhr progression on the tweaks. He basically has a stage 2 with RR wheel like you but with a 500ft elevation and in the same heat. It gets 95+ if not 100+ around here with the water at 85+ because it's just sitting lake water. Humidity around 60%.
Rodney said he was 2 ,almost 3 mph faster in the new orleans climate/location

I will be in some cooler water this weekend so I will see how it runs I may try to talk Jerry into taking a little out of my prop when he is in Nashville if not I will send it to him I would like to be at 8100 I have never seen 8150
