yea baby...i gots 2 aquamist water injection systems on my tahoe...
everytime i punch it...the cyclinders get a nice steam cleaning...and allows me to run more boost with the fuel mixture i gots without ping.

but like the company name...it's a mist...like a fog...not like a farking hose mang...it's so hot in there that it gets turned to steam real quickly too!

as far as bike tuned for 87 pinging...yes...you can use higher octane...but it's just a bandaid..cause in reality...What's really making it ping when it shouldn't???? aha!!!!!

 

I understand all about water injection, but if you don't spell it out there's that one person who really messes up. Kind of like pouring paint in the exhaust can

 

Ya Tahoe -- the aquamist is a bullet proof little unit in my book. I betcha I ran 300 gallons outta it with zero problems. On mine it started squirtin at 5# but I had it mounted on my uptube right near the turbo so it would atomize as much as possible. When it's fightin positive pressure it tends to stream instead of mist.

 

i ran alcohol/water mix for a bit and my exhaust smelled so good...but now it's breaking everything...
truck still runs but engine mount keeps busting...
i gots 1 unit coming on at 3lbs and the other at 5lbs...i'm running lower boost cause mah truck can handle that much as my injectors are all maxed out.
i love the thing but it's so not streetable it sucks for commuting and it's so hard to keep it in great shape to run well all the time...

it's all about bikes now baby!!!!!!!

 

Alchy is a bee-yatch ... will cool the **** outta your intake charge (and add a couple ponies to boot) but is highly unpredictable. My motto -- drink alcohol / spray the water

 

Ok guys, let me start off by saying that I understand and totally agree to use fuel of the proper octane. Anyone saying that 93 octane fuel is cleaner burning, higher quality, blah blah blah is full of it. My F3's manual states to use 86 or better octane fuel, so I was planning on running regular 87. BUT, I removed my tail fairing last night to wire up my trunk kit and saw a factory sticker on the frame/tube under the fairing. It stated, among other things, to use 91 octane... WTF?!

 

Well that's an odd place to be putting a sticker. Try running the 87 and if you have some knocking then move up a grade at a time.

 

haha, yeah that's what I thought. I'm going to stick with 93 right now since I'm running a lot of carb cleaner through. For those of you that don't know, most fuel system cleaners lower the octane a bit.

 

A rule of thumb, higher compression the higher the octane, with proper fuel mapping or jetting.

 

Have you read any of this thread? All of our bikes are high compression, however the manufacturer has built them for lower octane fuel. As a general rule of thumb, I suppose you're right... but that applies to cars moreso than bikes. Larger/heavier internals lead to more friction area, leads to more heat, means a higher propensity for pre-detonation.
