What's the best mix?

[Dave]

I've done a lot of searching but came up with nothing. I have a base DevilzOwn WI kit on its way. Should I use just Winter Blue washer fluid? Is its mix 70water/30meth? I am not sure how much boost I'll be running, whatever it takes to break 300, so atleast 20psi+. Is there anything with a 50/50 mix? Or would that be too much methanol? I'm not sure how methanol is affected under combustion and compression at the same time.

washer fluid is 50/50 you can run straight methanol like i do,seems to work great but i started adding 15% water

A few questions for you then. Why did you start adding 15% water? Does the mixture need to be diluted for other issues or are there gains with a dilution? Also, where do you pick up straight methanol and for how much?

[Devilsown]

I recomend starting with a 50/50 mix and going up down from there and see how the engine reacts to it.

I use a 50/50 mix on 29psi and it works great!

That is of course until you raced that honda and ruined your engine :/

[southkurtk]

lol my engine isn't ruined.... yet!

You won't break 300 with a stock head and stock T2 turbo if this is a chassis dyno and were talking WHP here. The turbo simply doesn't flow the air, or let out enough....and the head certainly doesn't do that either LOL. I've seen 334 WHP on the stock head but that was at a whopping 34 PSI boost from a 50 trim stage 3 .63 turbine turbo, a turbo that flows like 5 times over what a stock T2 can on the intake and exhaust.

EDIT- Bryan, are you talking about the engine in your profile with the ported G head? If so that will help, but the stock T2 turbo will really put you down. I made 270 WHP at 19 PSI with my G headed 2.2 setup but that was with a super 70 and .63 turbine and I also had a few more mods than you. I think with a stock T2 turbo I would have been more like 240 WHP at 19 PSI. And this is with a 2.2, a 2.5 is gonna be even more restricted by the .48 turbine. If I were you I would slap a .63 turbine on that stock T2 turbo and then I'd say you have a MUCH better chance at breaking 300 at boost in the high 20's.

I run straight methanol. Why add something to the engine that does not burn? The meth has awesome octane and cools great. We have ALOT of methanol injected cars we have built and we run 100% methanol in all of them.
P.S. washer solvent is rarely 50/50. The last one I checked would not even burn. They change the mixture depending on the time of year.

The reason water is added is because it drastically cools the intake charge. Cooler charge-more power. Yeah of course straight methanol is the best, but guys run alky injection on daily drivers....that could get expensive!

[EvilcowRoland]

Do I understand you correctly that you're injecting straight washer fluid into the engine? I'm with turbometh, I can't get that stuff to burn at all. Of course, it could be the cheap Wal-Mart fluid I'm using too. Are you guys cutting it with something else and are you using these with an extra gasoline injector or instead of the extra gasoline injector?

Why would it get expensive?
YOu cant drive around constantly in boost.
Its what...maybe 2% of your total driving time???

If you really are boosting that much then you are going to use a lot of fuel obviously and there is no way to avoid that cost. Its not like your gas tank is going to be any less empty and people here are spraying tiny amounts of methanol anyways....on the rare occasions they are able to blast away at higher boost levels.

I floored my daytona around everywhere, 300 WHP setup with +40's 3 bar 22 PSI and I averaged 21 MPG which I think was excellent for 75% city driving. All highway I would get 27-28 MPG. This is all in a heavy fully loaded daytona.
2%??? LOL, maybe you should ride around with me a little you will have a lot more fun! It's more like 25+% for me, WOT every chance I get. My BOV works overtime! I stay out of main traffic and go the back roads. Methanol is not cheap, it would get really expensive for me anyway!!!

[turbometh]

What are you paying for methanol? It is about $2.20/gal here. We stock a 55 gal drum for all the cars we install methanol injection kits on.

[moparzrule]

What! It's twice that here. 4.XX per gallon, can't remember the current price. You get a business discount? Or a buying in bulk discount?
