I figured the local Meth junkie would fill us in.:wink: Thanks Dave.

 

Cause you get less BTU'S per gallon....it is a less energy dense fuel...
So not only do you need to pump more, but the PER MILE COST (you get less miles out of a gallon) is HIGHER than straight gasoline...true for everything i have read/seen....it must be priced around 35% less...so about $1 less per gallon to break even!!!
On a flex fuel car, you can buy either...
But a MINI, must be tuned and modified to run e85...and you must reflash to go back to e-10....can not really do a random mix either....computer cannot do it...but if you have 2 gallons of e85 left and add 10 or so e10, car should do OK on the e15(ish) mix.....
So when you find you cannot get your e85 on a roadtrip (even the masspike, out usual e85 supplier in mass can be out for DAYS at a time), you would have to get your tank near empty...fill you tank, then reflash at the pump...:crazy: when I lived out in Joplin, I knew of one or two chains that sold e85...but get out of the farmbelt...it gets rare and MORE $$$.
So let's say you get 340 between fillups with a regular mini...you MIGHT get 250 miles between fillups with e85...kinda sucks...
Guess for a track only car kinda OK...but no long road trips unless you want to find ultra rare (in my area)e85....

 

I've used octane boost before. Not in my MINI. The super charger makes fixed boost base on rpms. You need a car that can use it, benefit from it and is tuned for it.

I used it in my Talon and WRX. In the Talon I could raise the boost to use the advantage of the increased octane. No real CPU control for the boost on those cars. For the WRX I had a switchable tune to allow more boost.

By itself octane boost won't do anything but waist money. Like people running premium gas in a car that doesn't request it. There are better octane boosters than 104+ also.

 

I'd agree with not using it all the time. If one did I'd guess it would be costly. Maybe use it when you are going to track your MINI. As far as it working, a lot of products have a strong placebo effect & that can cause the butt dyno to go out of spec. I'm not saying it does or doesn't, because I just don't know.

 

Depends...
If you had to use a tank of crap fuel. You might...say 90, with a tune for 93/94..
But if added to 93...very little change..if you read the directions on the bottle...you need Much more Than ONE bottle to make much of a difference....
Not sure which product 104+ adds...MMT (DIRTY STUFF..will make you plugs a powdery red/orange)) OR BASICLY dissolved mothballs(one of the 3 common chemicals anyway)..the two most common additives used as a octane index improve...heck many folks buy chemicals at home depot...and make their own mix...same effect...lots of homebrew formulas ...

 

Those octane booster don't do crap. They say the raise your fuel octane 4 or 5 even 10 points. Most people would think 93 + 10 = 103 right ?
Nope ::nonod: it's 93 + 10 = 94 they trick you with the marketing not telling you each point is .01 so 10 points is really 1.0.

It's just like wax marketing NOBODY makes s a 100% pure Carnuba wax because 100 % Carnuba is hard as a rock and you could not spread it on a cars paint.

 

.01 x 10 is .1 not 1.0 lol

 

Have Fun with E85 but its not worth it in the end. You need larger Fuel injectors and a better fuel pump.

I have Meth and it easy as the Aqua Mist system does everything for you and it runs off the duty cycle of the injectors which in my car are 450 cc.

I can run any fuel I want and its always available everywhere at every gas station so I don't have to find and overpay for E85.

 

Youve got to figure, those are mostly turbo cars where they can also raise boost pressure or add CFM with a larger turbo. Not to mention they have more tuner friendly ECU's.

Being an R53, the only way to raise the boost is to spin the S/C faster (smaller pulley) going smaller than a 17% reduction doesnt make much more boost, but a ton of heat. So that would be very counter effective. So you would spend probably $4K to get everything so it can be done right, but you would only probably gain 15-20 HP if you could get a good tune on it.

Dave, E85 keeps the engine internals clean too, just because of the volume of fuel you would be using. You are right about meth keeping everything just as clean though, and meth keeps the manifolds clean too, not just the intake ports and combustion chambers.

 

I'm not sure it is snake oil, but does your MINI really need it? Where I live it is no problem buying 91 or even 93 octane.

When I still had an MG I used 104 octane boost with real lead. My MG did not have hardened valve seats so the lead was needed, the octane boost was a plus for me.

 

Yes the MINI can adjust timing to compensate for the octane of the fuel being used. My thought is that it is there more to retard the timing in case you buy a tankful of carp gas. It will advance for higher octane, but I wonder how far it will advance on a stock tune.

 

It's awaste of money. Only buy Shell or Sunoco 93 or 94 fuel and you will be fine.

If you really want to make a real boost in your octane add a Meth kit fill it with 100% VP M1 Meth and have Jan tune your car for it.

For bonus fun run a tank of race fuel 102 with Meth.....:devil: whoo Hoo and the smell is awesome.

 

So how many octanes does this carnuba give one???

 

Try a gallon of Xylene or Toluene and a capful of ATF . Back in my turbo VW days, I often heard that adding this to 3-4 gallons of 93 octane would yield a substantially increased octane rating.
Was too chicken to try it though.

 

Yup you are correct nice catch, my bad. :frown2:

Fat fingers on and iPad and old are my only excuses. :lol:

 

Guess they never talked to RMW, aka, Jan....
Pretty much says the opposite....

 

^^^ yup, my car runs great on race fuel 105 + w/ VP M-1 Meth and I have been told by people behind me it smells great also.

 

I wish I could get 93 octane gas but only 91 octane is available in my area of California. I have frequently thought of adding 104 to a half tank of gas for an Auto-X event with the idea that might get the octane up to 93 so I would get full power out of the car.
Does that make sense?
Anyone experimented with 104 with the thought of just getting from 91 to 93 octane?

 

Whoa there, its my understanding that E85 has to have a specific system to run and trying to run it in our cars would be quite catastrophic. I seem to recall something about E85 messing with the fuel systems of cars designed to run on it. I may be misinformed, but I don't think I would even risk that stuff in my mini.

 

Just go to any speed shop and buy a 5 gallon can of VP race fuel and add it to your tank and that will give you a REAL boost in octane.

104 and other additives really do nothing and are a waste of money.
