Anyone done the 215HP to 255HP upgrade?

[Carboncow]

I'm due to rebuild the SC and note it will be approx. $500.00 when I'm done if I pull it myself. I saw the forum supplier has a new SC kit with bigger injectors and different SC. I'm curious if this is the only difference between the 215 vs 255 and thus the internals are safe with this upgrade.

If you had it done was it very noticeable especially for pulling a tuber or high end speed?

Tell me about your experience.

We can do the rebuild for $425 or you can get the bundle. You will most definitely notice a power difference with the injectors and the X Charger. Well worth the money if you are looking to upgrade performance esp since you are due a rebuild anyway. Another thing is we will give you a core credit for your current SC if you choose to send it in to us.

Thank you. I know I"ve read this before but don't have the answer here. Does the $425.00 including shipping back and forth? I think that's where I came up with my (almost) $500.00 theory.

Also, I can assume from the discussion that the X Charger/Injectors are the only concern with the extra HP. No other internals need upgraded to handle the additional stress?

$425 includes return shipping, and yes, the injectors are the only thing you must upgrade to run the xcharger.

This is interesting. I thought the 255 had a different intercooler as well? Or is this just a different SC that adds some HP but not as much as the 255? I will be due for the rebuild the end of this season and will be starting to gather info.

From what I have gathered it appears there was an intercooler upgrade as well as a software upgrade for the OEM. Maybe hfgreg can comment why the X-SC upgrade doesn't require (but could benefit) from the intercooler and/or software.

I've crossed the project off my option list as I've read two forum posts that said the upgrade consumes a lot more fuel, a lot more!

Thanks for staying tuned into the post....do you know if this X-SC is the same as the 255 SC or just another brand of SC that happens to offer more power? That also seems crazy that it would consume that much more gas.

 

[Carboncow]

No clue about OEM vs aftermarket but I'm sure Greg will chime in since they sell them and he's quick, polite and knowledgable!

I wish I could find the post (another forum) but I don't see it in my history. The guy made it sound like he even removed it because of the consumption! Maybe he just want back to his old SC when he was due for the next rebuild.

My SC comes off tomorrow (weather permitting) and I will be documenting it with photo/video for those interested simply because all info I've found on the intertubes shows a ski...and hoses in the way look different (to me) on the C180s.

OK....so a quick breakdown:

x-charger is same for 255/260....it's an OEM supercharger that produces more power due to larger wheel. http://www.pwcmuscle.com/sea-doo-x-charger-and-42lb-injector-combo-1077.html

The external intercooler is needed to get full power from the xcharger, and instead of OEM we recommend using a fizzle intercooler. http://www.pwcmuscle.com/fizzle-f1000-intercooler-complete-kit.html

Add a v-tech tune and you'll be making more power than a 260 and really flying on the water. You'll need the tuner and a tuning credit. http://www.pwcmuscle.com/v-tech-tuning-ecu-flash-credit-for-sea-doo-4tec.html
http://www.pwcmuscle.com/v-tech-hand-held-map-tuner-x.html

Just make sure to get an appropriate jet pump impeller to take advantage of the extra power.

That's some great information I will have to use at another time. This stuff is above me but I at least know who to talk to when I am ready.

 

[Carboncow]

Price went up astronomically too! Going from a X-SC and injectors for $1200 to a supercharger and more makes it a silly build for sure!

 

[XP 787]

Replace the supercharger wheel with the ET127 and make more power. It's cheaper.

Good info. I see the item under the performance section. What is this about needing another fuel regulator then? I see only one listed for $370 so now we are at $350 (sale) on the wheel. So we are pushing $800.

What do you know about the fuel regulator requirement?

EDIT: I see it needs bigger injectors too. So are we back to needing an intercooler to handle all this extra hot air?

 

[XP 787]

Yes you still need bigger injectors or you will run lean and ruin your motor.

External Intercooler is not necessary but you will gain rpm with an external one vs the internal one you have now. +1 on the Fizzle Intercooler btw.

Fuel pressure regulator is also not necessary at this time but with some more engine mods you will deff need it.

Upgrade your impeller or you may be on your rev limiter.

Since you already need a sc rebuild, the x sc and injectors are the shortest and easiest route to a little bump in power without changing much. Slippery slope after that....

Sounds the safest and easiest route. Seeing to much conflicting info on the drop in wheel and what is needed to utilize the benefits, plus I have a brand new wear ring and prop so I don't want to upgrade at the moment. . Maybe next season I'll spend the $2K and do it right!

 

[XP 787]

Weather you go with the Xcharger or 127 wheel you will still need bigger injectors.

Also unless you are buying a brand new oem xcharger it is still going to need a rebuild IMO.

Im pretty sure [MENTION=1]JoeZ[/MENTION] installs upgraded wheels at no additional cost while doing a rebuild. You can purchase the wheel from their online store PWCMuscle.com

 

[Carboncow]

The SC is in transit to Joe.

I just did the math and it looks like my cheapest option would have been todo the X-SC with 42lb injectors combo as Joe gives a core on the old SC which would make the injector portion feel free. This would have been cheaper then dropping in the rebuild, ET127 & Injectors at this point...of course if the ET127 is a better wheel then there is an argument.

I guess I got till tomorrow to figure this out!

My goal at this point is just to make sure the boat doesn't feel under powered. I'm only using it to have fun and pull a tube from time to time. I'm coming from a Center Console with a 225HP Yamaha outboard that would do 50MPH but we seldom needed all that power.

At the moment I'm feeling I need to run the boat this summer and see what I think. If it needs more then I'll upgrade next year and I'm only out $300'ish on the rebuild.

I"m still curious if the X-SC/injector combo or the drop in is wasted money w/o the right prop, fuel regulator and/or intercooler. I just bought the boat and have spent about $1500 to get it looking new, pretty and dependable. I may have to let it ride on the fun factor til next year!

 

[XP 787]

Awesome!! Enjoy the boat!! The most important thing is that you are getting the supercharger rebuilt. Joe did mine a few months ago and my ski is running great!!

Since I got your ear and you are being very help with my information gathering (and indecision) I'm wondering if I should go with the cold air intake setup Joe sells. My only question is what do you do about the oil return/catcher system?

Figured if I go with the X-SC it sounds like this is all the more useful.

 

[XP 787]

You can either get the Riva catch can setup which is about $140 or you can build your own. Just do a search for a DIY catch can setup. FYI I gained about 200 rpm by just installing my intake (4" Kanaflex"

Thanks. I just found the DIY and it's great! I'll assume this all just mates up to the hose that comes off the existing air box (that goes to the crankcase located above the SC)?

Correct....

 

[Carboncow]

Correct....

Not seeing as much DIY in the air intake arena. I'm sure I'll get the kit but why do most of the kits move the filter to the front of the engine...is it cool air or a keeping it dry thing for the jet skis?

Are you speaking from experience on your RXP or did you do this to a C180?

Yes I am running my 4" kanaflex to the front to help keep it out of engine bay. It still does get warm up front but nothing like being in the engine bay. Also, this is on my RXP. I wish I had a Challenger lol
