Yeah i found how it technically works but i was wondering in how much time does the methanol run out,how much of it contributes to the total fuel used...It just seems impractical to drive 200-300 km to another city with the methanol injection kit(having to fill up the methanol every 100km?)...this is what i don't understand...

L.E:I just found something...that you can put windshield fluid in the injection kit tank because some of them contain almost 40% meth,is that true?
And how are the other supra owners doing it?Do they just buy pure methanol and mix it manually or just buy windshield fluid ?
I'm confused

I've read a few things and it seems to be about 3 quarts of methanol - 16 gallons of gas, but I don't know where to get methanol in the first place. As for the window washer fluid, some of it does contain about 35% methanol, but I have no idea if it's safe to use in the injection system. I'll keep digging, though.

With a separate meth injection system you can make at least 650rwhp (6spd) on 93 (r+m)/2 pump gas.

You can get meth direct from gasoline distributors - the same place you get pure race fuel in barrels. You can also get 1-gallon tin containers of denatured alcohol from home supply stores that work in alcohol+water injection systems too.

Omg, please don't use windshield washer fluid! It contains soap - something you definitely don't want running through your alcohol injection pump. Also, (in case you were wondering) don't ask about the pints of octane booster off-the-shelf in auto parts stores because they don't work either - if you read the label carefully, it talks about raising the octane by "points". When you see "raise octane by one point" think 93->93.1, NOT 93->94.

The alcohol injection only sprays when you're boosting. If you drive your car like a granny, your alcohol supply will last forever.
Here are your (proven) choices:

1. Run enough a high enough octane of race fuel to match your boost level. Note you can mix high octane race fuel with pump gas for mid-level horsepower needs.
   This is by far the most popular choice for high horsepower Mkivs. Every Mkiv owner I know that runs pure race fuel 100% of the time (and doesn't formally compete with it in serious drag racing) has never blown their engine.
2. Invest in an alcohol injection kit (again, alcohol is easy to find!). Don't plan on more than about 650rwhp (6spd) with this option, since the pump flow and nozzle sizes are limited.
3. Run E85 (this choice is growing in popularity, as more and more gas stations are offering this fuel). It's a very good option since E85 is much less expensive than race fuel (its not much more, mile-for-mile, than pump gas). On the downside, your full tank of fuel gets you half as far.
4. Run 93 octane fuel and never boost more than 16psi. This choice is your easiest one, of course.
5. You actually can mix a few gallons of pure Toluene into your 93 octane pump gas for a small octane boost.
6. Propane injection will probably work too, although I don't have personal experience using it in an Mkiv Supra.

All other roads lead to melted pistons. Don't say you weren't warned. Lots of other folks will tell you this and that and whatever is okay. If you follow my advice, and the components are expertly installed, well maintained, and regularly tested, you'll never need to buy a new shortblock. If anyone offers you less conservative advice, I advise you to ask them if they'll pay for your new shortblock when it doesn't work!

Again, don't mix the alcohol into your gasoline. Here are your (proven) choices:

Firstly,thank you for taking you're time to respond in such a manner
Secondly,I don't plan to take my supra higher than 700 hp(~600 rwhp).What would you recommand for this? w/m inj kit or alcohol inj kit ?
The windshield washer fluid is supposed to have ~60% water / 40% methanol...

Glad to help.

By "w/m inj kit" I assume you mean a water/methanol injection kit. Methanol is one type of alcohol. So a "w/m inj kit" is the same thing as an "alcohol inj kit".

For 600rwhp I recommend pure 100 (motor) octane unleaded race fuel. A "w/m inj kit" should work fine too, as long as it's properly installed, well maintained, and regularly tested. If the turbo you choose is capable of more than 600rwhp (which I hope it is not), your boost control will have to be rock-solid.

Again, you don't want the soap and the bug-melting chemicals in windshield washer fluid running through your w/m inj pump or your engine.

I recommend 90% alcohol/methanol, and 10% water for your optimal horsepower & octane boost. 60% water & 40% alcohol is cheaper, of course and perhaps slightly higher in pure octane boost. However, octane does not = horsepower. You loose too many BTUs of heat with 60% water...and therefore too much horsepower is lost along with that reduction in heat! 60/40 might be fine for some ricer honduh or 'billy rustang owner (no offense) trying to put a hitch in his giddyap, but for an Mkiv Supra Turbo running 25psi+ of boost, it just isn't anywhere near optimal.

Wait,this makes me confused...so if i run JUST race fuel,can i drive without the water/methanol injection kit(is it no longer necessary?
By race fuel what do you mean?Pure race fuel(found near the tracks) or fuel with high-octane number?

Yes, yes, and yes.

For example, refer to "MotorSport 109™":

Here's a local supplier of race fuel in Romania:
