MD you got mail

Phillip the CDI is different because it does not monitor the cat con temperature, a far as timing I could not tell you if it is the same or not, all I know is that the Advent and RIva cdi's will swap in place.

Just to throw my two cents, in € of course
My friend has a stock 2000 US gpr and I had a stock 2001 Euro GPR. While mine was still stock we did several back to back runs and swapped rides for our tests. We both agreed that the Euro boat has better holeshot and inched away from the US boat at WOT runs on glass. Didn't have any radar or GPS but it was obvious from side by side comparisons that the Euro model pulled harder.

Thanks again for your help. I find because there are so many variables with this stuff it takes a while to get it all straight.

This increased perf is probably due to the different jetting allowed by the use of the D plate.

So I guess I should be happy I live in Canada and have a European spec boat. Now only if we could get that dollar problem fixed so everything wasn't so d*m expensive.

Cool

Oh yeah there was one difference.... the euro boat had sponsons in the down position. The US boat had them up.

Philip, don't talk to me about the prices - they make me sick
Here's a few examples of how much my hobby costs me:
02 GPR: $11000
92 octane super plus: $4.20 per gallon! (so please tell G.W. Bush to stay out of Iraq )
Riva Stinger 2: $732

Here's the question of the week, what is the stock jetting sizes on a Euro spec boat? It would be nice to know if we want to run the D plate and this would ensure the warranty would still be good I would think, not to mention they should run stronger!

GPeiRe...Your gas prices are high because of the TAX that YOUR GOVERNMENT puts on it.
If GW goes to Iraq oil will be $10 a Barral...
Kick there azz and pump there oil.
Oh the He11 with it...just nuke Isreal and all this bull will be over with.

Voodoo,

Stock jetting on european boats is
92.5 pilot
135 main
1.2 n/s, 115 spring (I think)
Accelerator pump feeds all 3 carbs.
Not sure if it would be a case of a straight swap due to the US accel pump only feeding carbs #1 and #3. Perhaps this is why the euro gpr has a slightly leaner pilot. But I AM NO EXPERT on this stuff.

JetEd,
Yes I know my government is the cause of the high price I pay for gas, they stick it to me up the azz for lots of other stuff too...
I didn't say G.W Bush dictated the price of Irish petrol (gas)
But instability in the middle east pushes up the price of oil for everyone, before my government gets their turn to shaft me..

2001 GPR...

Using Riva D plate in a stock boat it turned 7260. This is with only a pump plug kit installed. It turned 7270 before installation (with CAT). Benny says he feels more throttle response especially after a period of running 6 KNOTS. Thats probably because the under hood operating temps have been lowered. He also says more mid range pull.

Testing was done on cool dry days (65 air 50% humidity)

On a 95+ % humid day it only turned 7140.

Austin you would need to feed more fuel if you install the D-plate.

The real world back to back US vs EURO GPR test is the real deal here and everyone who has done it agree that the Euro is faster.

This has all been great discussion to read .........but have we answered the question yet. Does the R&D D-Plate yeild more RPM's than the "traditional" D-plate. I'm about to install the R&D and this would be nice to know. Anyone????

I am running the R&D D-plate but did not do a back to back comparasion

Faster where Fernando???? Side by side!!!! If so that’s no good because two boats set up exactly same still don’t perform EXACTLY the same. Sorry but the only real world proof I would accept is to move the carbs and stinger between the same boat and then still that would be tough because of all the other variances. Heck, look at the difference in the 2000 verses the 2001 as far as performance goes. Bots are exact though, Correct! I don’t think so.

Anyway…

I was not talking about the Euro verses USA GPR I was posting results for Bennies boat with a D Plate so I could answer part of the original question for this thread.

As far as jetting and the position of the screws go I disagree. I am running stock jetting with stock air box with out the elbow, free flow, R&D D plate 13/19 washer removed, 2 Bar, 50mm nozzle, stepped sponsons. Lows are factory and highs are 1 1/16, 1 and 1 1/8 with excellent piston wash and no loading up for extended periods of idle or 6 knot zones. That’s less fuel it was fed with a CAT and the boat pulls 64.4 @ 7150 before the low fuel buzzer. The lower R’s are due to Rivas top loader, stock compression and the washer removed.

As far as the 2001 being faster than the 2000. The only explanation would be the stock impeller, because the hull and pump components with the exeption of the liner are the same. The carb improvement was only made for rigidity and the waterbox change was made to accomodate same parts for differente ski's

The different jetting will not show results on top end speed but on acceleration time

Fercho,

my 01 was at least 1.5 to 2 mph faster than my 00 when both were in stock form.

So when you compare a Euro 01 to a cat-con 00, your not really comparing equal GPR'S.

Everyone is indicating that the cat-con GPR has higher operation temps in the engine compartment, and again I ask has anyone done the following???


take a stock gpr with a cat installed.
remove the seat and run at wot on glass.
Feel the exhaust chamber near the cat for
temps with your left hand while running at WOT.. then do it with the d plate.

I think you'll be surprised about what you'll find..
