80 mph FZR/SHO 'recipes'
There are some very fast skis out there now, and quite a few setups have been tested. We have put threads together on how to achieve 80 mph on RXPs, GPRs, etc in the past, and it would be interesting to do the same for the SHO engine skis.
So far it seems like the least expensive route to 80 mph is something like:
Good rideplate - VX or R&D or Riva later
Grate - R&D or
SC wheel (many choices here, how much boost is needed?)
ECU or reflash
I am curious what is the cheapest, simplest way to 80+ mph? My guess is that R&D R2/Powershot, plus a low boost wheel ... is the C3 close to the same as the Riva B1? Is an upgraded SC shaft and BOV both necessary?
Is an upgraded intercooler required, or do the cooling mod updates help enough with a low boost wheel?
When do you really need to upgrade to 160 mm liner and impeller?
Exhaust mods? Is there an aftermarket waterbox yet, or has anyone had good results modding the stock box?
Are there any setups that run 80 and don't really need a Powershot, that just the R1/R2 provides safe fueling?

160mm liner and pump vane mod is primarily to reduce launch cavitation.

The Speed and Mod Database is an excellent place to start looking for the 80 mph 'recipes' your seeking.........as you'll be able to see what the different hulls run speed-wise with the various mods in variant conditions.
So buy that Yammi already so we can add ya to the family! You know you wanna.....

Running one of these motors lean...in the pursuit of more power......can be a very costly mistake.....

Bottom line, you might get away with running a C1 without a better IC since you're in a cooler climate, but anything bigger & you'll be leaving a lot of performance on the table without upgrading.
