mr.seadoo

i am new to the forum. i do not own a honda, but i own a 3cyl rotax engine that makes 460 hp @9000 rpm @33 psi. here is what i have done
lightened crank
lightened pistons special for turbo
cnc ported head
leightweight valves
custom intake mani
autronics sm4 updated version
antilag
launch control
cdi multispark "autronics"
knock control
racepak dash
walbro fuel pump
83lb inj
bored throttle body
garrett water to air intercooler
garrett turbo "custom lightweight inducer and exducer around .60 .63
stainless exhaust housing
34mm turbosmart wastegate

probably other things i forgot to mention.

i would like to know about running e.85 on my setup. is it worth it what will i gain. just curious

OH ITS ALL ON MY JETSKI THATS HAND MADE BY ME.

mr.seadoo

here is a quick vid only running 16 psi@8000 rpm's

mr.seadoo

ski idles @1750 when in launch control it will rev to 2500 rpm and build 14psi

Boosted-EH-804

This thing is nuts I want to see some vids of it at 33psi that must be some fun **** there. So if your seado is this fast what the hell do you drive on a regular

mr.seadoo

i dont drive fast cars. just drag race jet ski's.
someone on here knows of someone that i can speak to about e.85.

mr.seadoo

please lead me in the right direction. someone know of somebody to talk to

I believe that e85 would work great on your setup and really can not think of any reasons why not. An engine is an engine and as long as it is fuel injected, has pistons, and is powered by combustion, then the same theory applies. The higher the octane of the fuel, the more power that can be extracted safely from the engine. I am assuming you are on unleaded pump gas so my thought is go for it. You will see a better torque curve at the boost level you are at and may be able to squeeze out a little bit more power out of it. That thing is sick and would love to see some more videos of it no matter what the power level. I have personally never seen any high horsepower jet skis.

seriously i am really interested in how you did this and how it is tuned and what not.

This is amazing. Please post more vids. Link to a build tread.
Thanks

It's really interesting and i think it will work great if u choose an accurate water pump.

rs250nut

**** that thing is crazy, I thought my friends rxp 225 was fast. Just to add, the higher octane fuel will be more resistant to knock.

mr.seadoo

ty for all the compliments.i felt kinda funny posting up on a board that is around hondas and here i am with a jetski.

i am not afraid to ask questions so thats why i just started my thread.
the guy who designed my setup is a world renowned jetski builder in melbourne australia. i spoke to him awhile back about e.85 and said it would be a good idea but we need more data from my engine to see how its handling boost now. i increase boost 2 psi at a time and send him the data files. so far so good running @22 psi with **** pump gas and no signs of knock.

for now i will give you some ideas on how fast my ski accelerates @ 16 psi in that vid going off my data logger without a stalker radar.
from dead stop with ski in launch control @ 2500 with 14psi ready it does 0 to 80 in 3.5 seconds on pump gas.

Do a search on here for e85 and do lots of research. There are gonna be a few things that you will have to change when making the switch as you will need to flow more fuel. I absolutely love that thing and am willing to help the best that I can.

Another thing to add would be to make sure that where ever you happen to get your e85, you need to make sure it is a proper mixture AND is consistent.

Here is one way: http://www.brackettech.com/showthread.php?t=1059

You can always search for more.

Basically e85 is a cheaper alternative to race gas, and burns cleaner. It can also be easier to get a hold of (depending on your location).

As for anyone who says it does damage to various parts or the fuel system, you will find many supporters running stock systems with zero issues (only consistent thing that seems to happen is white, non-harmful residue on certain parts). I've yet to see any real evidence of damage due DIRECTLY to e85 (besides when people have used improper mixtures). There are even people on this forum who have been running tests to see what e85 can do to parts.

Again, you can search and draw your own conclusions. Good luck with your setup though, that seadoo is BAD! I don't know that I'd have the ***** to ride that!

blackie204

i bow to you haha this is purely awesome

boostedeg302

For the record, when I said you might have to switch a few parts around I was meaning to support the higher fuel flow that e85 will require. Things like larger injectors and such.

E85 will work much better than pump gas as long as you have enough flow to support it, your fuel system will need to be 25-30% larger with E85 than if you were running Gas. I am sure the rest of your system will be just fine running it. The blends do vary some from station to station so an ethanol content meter might be a good investment for your motor.

mr.seadoo

where do you get a ethanol meter

LOL! I'm laughing because that thing is B A D A S S!

crucian

Check out www.zeitronix.com website about the meter. Like others were posting above, you will need a fuel system that can flow more. If you already have a high flowing pump you may only need to upgrade injectors. But ofcourse we don't know what fuel pressure you're running or your injector duty cycle. I had some engines that needed 50% more fuel added to the tune and some that needed less.

TurboK

Awesome..

mr.seadoo

I HAVE A WALBRO PUMP GSS 342 RUN AT 60 PSI NOW WITH SIEMENS 83LB INJ.
I HAVE A RISING RATE THAT IS A 1 TO 1 NOW. USUALLY RUN AT 27LBS OF BOOST. MY SET UP CURRENTLY IS A BIT RICH SO I MAY TRY THE MAP I HAVE AND TEST E85 ON THAT BUT I NEED TO GET A AUTRONICS FUEL ANALYZER.

OUT OF CURIOUSITY WHAT HAVE YALL NOTICED FROM USING E85, LAGGIER,LESS LAG. QUICKER REVS.

crucian

What have I notice from using E85? hmmmm.... pure happiness! For me it was quicker revs, and better response. Take note that I add timing while using E85. As for you running a bit rich now on gas doesn't mean that it's rich enough to run E85. If you are going to test it out, make sure you keep an eye on you AFRs and dont just go out and floor the throttle. Ease into it while checking AFRs. Oh another thing is, don't mix the E85 with the gas you have in the tank already. My gas analyzer was always my nose (yup, smells like E-something to me). lol....

Schister66

E85 can offer a higher octane than pump gas (~107oct), but it comes at a cost. The engine will require rougly 30% more fuel than with gasoline. Since you're already making good power at fairly high boost levels, i dont see what you would stand to gain with an E85 tune vs the current setup. You've practically reached the limits of your turbo and since your engine is still in one piece, the switch to E85 may not be worth your time; HOWEVER, if you plan to run more boost or change the setup in some way to utilize the benefits of E85, its a great idea. I run the corn juice in my daily and love it. I would recommend it to anyone as long as there is something to be gained by its use.

mr.seadoo

just a recap...

e85 = lower engine temps
less resistant to knock which equals more timing,= more power
105 octane pure man made.

what else did i miss
