Ultra 250x StockClass offshore mods
I recently bought a new 2008 UlTRA 250X. Planning to do some offshore long distance racing = lot of WOT driving in 1-4feet shop.
I ride in pretty cold temperatures as I live in Sweden. The mods I am planning is the following:
6* timing mod
TBM upper steering system
RD Deep fuel pickup
1 degree wedge ( Stock leagal? )
What rideplate, intake grate and sponsons do you suggest:
RD Rideplate ore the Adjustable TBM plate?
RD Intake grate or TBM?
RD Sponson or TBM?
Is it worth for me to do the Intercooler mod when the temps I am riding in are between 50f water/50f air to 75f water/85f air?
What more mods do you recommend that are Stock Class Leagal?

who's this DUBZ guy, does anybody know if he can even ride a ski??????????
ley me guess he rides a green ski too
Yes Do the intercooler mod, any assistance in reducing the air temps are benificial
offshore riding is a lot of WOT riding so heat will build in the cooler ( do the twin bottom mod, out at the top )

Thank you for the help
Will go with the RD plate, sponsons and the TBM intake grate then.
We are racing under the IJSBA Stock rules. And its a bit unclear what is legal or not, do anyone of you know it the mentioned mods are legal (wedge, BOV block off, etc)?
What lifter wedges do you recommend saw that hydroturf sells different types?

bov blocked is not legal, but you can put a small shim under the bov and be sneaky sneaky, best to get the r&d adjustment kit if you wish to race clean then you can check it regularly. see skips site for the method.
ic mod is a must for long wot, I would think even in the icy land of blonde babes you would benefit from it on long runs, we found after racing you can put your hand on the ic and its warm to touch not real hot like before.
get long wedges you can always cut short if you no like.
I use the full r&d package as they state the parts complment each other when put togther and I would agree, I loos little to no speed on a high speed turn and stay hooked up heaps better than other modded ultra's.

What about airfilters is there any benefits to by these? Witch is better Riva ore RD?
Are you shore the 1deg wedge is legal?
Regarding the TBM steering system what is recommended for a 175cm driver CC ore Offshore tubes? They are quite pricy so I don't want to buy unnecessary products...
Again thanks for the help
