Thread: RPMs Comparison
02-27-2008, 12:26 PM #1
When trying to trick out a 05 GTX SC (185 hp) and trying to get the most out of it...Everyone seems to discuss top speed and rpm. When I mod my 185 with a Stage I, I know I have to be adding hosre power. Is there a formula or an educated guess as to what horse power a 185 hp with a stage I, free-flow, and iridium plugs would get? I have read here where someone wrote his 185 hp could keep up with (or even perform better than) a RXT. Obviously the 185 was modded, so what's to give?

A lot of viewers seem to be interested, but only one reply...and a smart ass comment at that? Anyone else? If not...any more jokes?

Nobody knows because the average joe doesn't have a dyno and HP numbers aren't given with Stage 1 kits.
If i had to guess, 180 HP tops. Your ski isn't really 185 HP as advertised. RXP's that are advertised as 215 really dynoed at 197 at Rotax Racing.
The stage 1 kit is not all about HP. It's about making the ski/pump more efficient.

Fair enough explaination...only took 3 days to get. Thanks Jerry.

S-D has usually been under rated 98 xpl.... triples...130hp VS 160hp. Even though The xpl is still raced in a modded form and the (raider?) is in the scrap heap. Pump effieciency and hull drag have to match the hp...it seems as though S-D is very good at that. That is why hp is almost insignificant.

I get that noone has the damn dyno. It doesn't take a rocket scientist to know that...What i am looking for is the SeaDoo scientist that would know this, or at least know enough about it to say, forget horsepower and concentrate on tope speed/rpm.
Maybe I could have rephrased my thread to something along the lines of...Are there enough mods for a GTX SC (not intercooled... since stating 185 hp means nothing now...185 hp is/is not not 185 hp) to mimic a stock RXT/RXP whether 215 hp or not?
Can a GTX SC (non intercooled) with mods fair with a RXT/RXP? If so, is it fair to say the horsepower could be equal or better to say "performance" is equal?
Maybe I should start digging my way out of the confussion hole???
