ÄMNE:

we start building a new boat for the 2012 season here on Orust west coast sverige, i write the tread in english , but no problem if some one write in svensk .

the season starts with the UIM World Championship 2-3.3.2012 in Doha /Qatar , Lars Åkerblom has win the last 2 years the SM in Open Class and we are hopping for a good result.
the UIM worldchampionship is a 2 heat each 30 min race on the sea side.

the UIM jetski world organisation pays the airfreight transport of the jetski and the Hotel , as well as the Race fuel

some infos on the boat:

we have had a few option for the new 2012 race boat , after testing the 2012 RXP-X RS in october last year Havasu /USA , we decided to go with the new RXP-X ergonomie for the topdeck . we made the seat ,hood, topdeck in carbon fibre to get better acceleration and lower the gravity center for better handling

the bottom hull is from a GTR, as the straight-line stability is much better then on the new RXP-X RS (keep in mind we are running close to 400 real HP on a boat that is 90 kg lighter then a original RXP-X RS )

we have tested the GTR hull on the end of last year with a 330 HP test engine and competed the last SM race , but now we cut down the old topdeck to replace it with a carbon fibre one

( the new RXP -X is by far the best turning and handling boat ever build, but thats only up to 300 hp )

the bottom hull has been reenforced with kevlar and carbon, the ride plate is original , the Intake grate is a custom CNC machined piece of art from Seadoo centre australia ( its over 1000 USD, but it does not have a chance of breaking at high speed like the RIVA or RnDs

the Engine is a complete lightweight ROTAX RACING factory offshore spec. engine , that we will run with a bit higher compression and a Supercharger from SEADOO Centre.

we will run a target RPM of 9200-9250 ( RPM Limiter will be 9400 ) we have tested the complete last season with 9350 Limiter and had no problem at all in more then 15 heat races.

off course we have the engine sitting on ROTAX RACING solid engine mounts

the pump unit will be the ROTAX RACING 16 vein setup with a SKAT TRAK 14/20

we buid 2 engine with the same internals , so we will run in all training s and tests the spare with a more conservative mapping.

the ECU will be the 2012 IGNI Power from ROTAX RACING , with the new Digital touch screen.

we have only 14 days left to send the boat with airfreight to the first race :-

thats the basis GTR, that we tested allready with a 330 HP engine and original hull and carbon seat )


carbon topdeck 17 kg, (original weight 66 kg)

the engine parts


ROTAX RACING lightweight crankshaft , with lightweight gear ( pin locked), balanced



ROTAX RACING connecting rods , much lighter as original or Carrillo rods
M9 ARP bolts, ( Carillo rods are only M8 ) but the Carillo rods are also not bad at all

ROTAX RACING 2012 MAHLE Pistons lightweight & high compression , much better Ring design then original SEADOO, the 2013 SEADOO engine will have the same Piston OIl Ring design as the original Pistons are also made by MAHLE

Lycka till Lars! Vi håller tummarna.
Ska JJ också åka med?

Nice boat Malte!!

Lycka till Lars Åkerblom

Lycka till i Doha Lars och se till att inte slarva bort JJ på någon konstig efterfest.

we got ready just in time with the boat last night, they are now on the way to the Airport for the shipping to Doha, here some pictures




10 min later the hull was glued together with the carbon topdeck , we use a light marine construction compound



full color screen with real carbon frame, u can see the small warning LEDs for Oilpressure and Detonation warning



the 90 mmm exhaust system is custom made and ceramic coated , the mid pipe ( from engine to waterbox) is a high flow twin wall masterpiece

the battery is a 2 kg lightweight Li unit from ROTAX RACING

Bra jobbat mycket snygg maskin Malte ser helt galen ut.Hoppas allt går kanon i Doha och att Lars kör riktigt bra, lycka till nu och vissa vart skåpet skall stå. :clap:
