hey all I have a question- first check out this berg on E-bay[web]http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=4509911228&category=6719[/web]

notice the seller states the discoloration of the tamk due to Octane booster.

I was under the impression that Octane boosters will actually decrease the power in modern four strokes. is this correct? also...

would octane booster do that to a tank? :shock:
 
Hi Risky1,
Stagnant fuel and plastic exposed to sunlight = nasty discoloration of opaque tanks.

Regarding Octane Boosters:
Concentrated over the counter boosters are for the most part junk. Statements refereing to one or two point increases are in truth speaking of tenths (ie 2 points ~ .2). Can you say MARKETING! Sorry, am I bad or what? :D

In concentrations ranging from 10 - 30 percent, Toluene and / or Xylene provide for a substantial boost in Octane and increase power levels. Such Hydrocarbons are readily available over the counter as paint reducer.

Hope this helps.

Sincerely,
Dale
 
over the counter octane boosters

Hi Dale,Another myth discredited!We wont be able to see the mirrors through the smoke soon....nsman
 
HMMMMM.... Toluene.... so, speaking hypothetically of course, what would the proper ratio of said reducer/pump gas be to perform said increase in power. AND, how much if any damage can we expect to occur to our beloved machines once they have tasted this chemical concoction

EDIT: DUH :roll: 10-30%

I don't think i will actaully try this as i do not have the man parts big enough to use all the power it gives as is.....

Dang that tank looks BAD though. the rest of the bike does not look like it has sat in the sun enough to do that. Anyway- the person who buys it just need to pick up that tank that is for sale also....
 
i was going to say risky-don't let that stop anyone buying the bike: i was on the USA e-bay last week having a ganders and i spotted two tanks for sale then and bidding had reached a mighty $20 for one of them.

i would worry-not as you might say over there!

Hi Risky1,
It is possible that the opaque tank is simply stained from heavy metal additives which are abundant in cheap fuel and many boosters. However, it is most often a chemical change which takes place between the fuel and plastic.

Toluene:
R+M/2...114

Mixed with 92 Octane Premium:
10%...94.2 Octane
20%...96.4 Octane
30%...98.6 Octane

Remember:
Common metallic ingredient boosters will only raise octane 2-3 *points.
(Example: 92 to 92.3)

Hope this helps.

Kind Regards,
Dale
 
I thought that toluene mixed with gasoline at concentrations above 15 or 20% would not be too good for fuel lines, float needle valves etc...

Hi DaleEO,
Not at all. As a matter of fact both Toluene and Xylene were once upon a time (Pre EPA) favorable pump fuel ingredients. However, Methyl and Ethyl alcohols are quite a different case indeed.

Sincerely,
Dale
 
don't look ethyl. too late-she already got a free shot!

Your premium fuel is 92 8O holly crap it sais in the manuel to not run them on less that 96 i use 98 shell optimax ot bp ultimate with no problems

And dale about the octane boosters i have a magazine review with a few over the counter octane boosters achieving nealy 3 octane boost from one product and about another 2 or 3 common brands giving gains of around 1.5 to 2 being common for them i will try to find the articale and post it

cheers doug
 
Doug,

Here is an excerpt from another forum that I'm on:

"NA use pump octane ratings which is the Motor method plus the Research method divided by two. RON is the preferred rating method, the MON is older and not used much. I think NA is unique in using the average of the two and caling it Pump Octane (PON).
95 RON is roughly 91 Pump octane."

-Tim
 
I was told that as altitude increases you don't need as high an octane to prevent detonation....or maybe it was a way to sell us mid grade gas for premium prices.
 
BESIDES THAT, THE MODEL IS A 2001 AND NOT A 2002 AS THE SELLER ANNOUNCE
:lol: :lol: :lol:
 
R+M/2 = Research + Motor / 2 = Pump Octane Value.

As a former Chevron Research Technician in charge of L48 variable compression test engines I can assure you from first hand experience that current off the shelf octane boosters in proper charge ratio will not increase pump fuel ratings by one - two octane. However and as mentioned in an earlier post said products will likely boost octane by one - two points. A single point being equal to .1 octane.

Research and Motor octane numbers are derived from different tests with Motor values being of primary concern regarding the recreational motorsport enthusiast. Unfortunately Motor numbers are generally lower prompting many suppliers to tout Research values instead. (Indeed, marketing once again shows its ugly head). Overall the best method is that of using R+M/2.

Note:
Many European distributors state minimum requirements using Research or Motor numbers. An R+M/2 Octane value of 92 is more than sufficient regarding a stock Husaberg.

Aviation fuel introduces yet another set of variables including vapor pressure and fixed throttle / supercharged testing. Octane values do not directly correspond to that of conventional gasoline. In short order the use of aviation fuel will likely result in less power and reduced throttle response as a result of fewer BTU's per gallon and increased Reid Vapor pressure. (The later of which being to insure against vapor lock @ altitude)

It is indeed correct that all else remaining equal as the air density is reduced (High altitude) the octane requirement is also reduced.

I Hope this helps someone as it has exhausted me. :)

Sincerely,
Dale

in europe dale they mix the fuel 50/50 avgas and super unleaded.

Hi Taffy,
This is common practice in the US as well. Unfortunately the provided boost in octane is shadowed with an overall decrease in peak performance. (albeit slight)

Blending aviation fuel and pump gas does prove of advantage if vapor lock has proven to be a problem (ie High ambient air temperatures and / or slow going air cooled engines).

Kind Regards,
Dale
 
i've heard of this toluene but i'm not sure i didn't look for it years ago in a paint strore and it wasn't on any of the tins by that name.

is the mix 20/80 dale?

my friend now gets black box units that can modify the ignition curve in increments of 800 revs at a time. taking advantage of the extra compression available. on't suppose these after-market units ever fitted an old SEM or the new kokusan ignitionunits did it?

i use shell optimax as i think it's about the best going although i have to say BP has a very good reputation over here!

regards

Taffy
 
Hi Taffy,
Toluene is also known by Methyl Benzene.

I am a true advocate of the Vortex adjustable ignition, even going so far as to purchase software rights to said product. To date Vortex does not offer a unit for the Kokusan Husaberg ignition, however, I am indeed working on such. :D

Best Regards,
Dale
