Plumb it all under the TB and stuff, then put some vacuum hose over the feed lines. Nobody would have any clue about it unless they really knew what they were looking for.

i plan on putting the meth on the intake and then just covering the hose with wire loom. now with the dual stage it will be a bit trickier to make it blend in. but yea if u dont know what you are looking for it will be hard to find. but the engine bay is going to be a bit more cleaned up than a stock bay so it might be easier to spot.

Thomas was using a 14gph nozzle - 70/30
I'm running a 10gph/7gph -100%, soon to be 14gph/10gph (90alch/10wawa).........

how come most of the kits warn about going over a 50/50 mix?

is it because there components can't handle that much meth?

50/50 isn't that bad right? i mean its alot cheaper.

70% meth by mass here went from 292whp without to 314whp with meth, once Sam sends me my 3.2 pulley back i will head down to innovative and get re-tuned for 14gph (up from 10gph) 11psi and a better flowing exhaust
shit...forgot man. I'll get on that today.

so you went from a 50/50 mix that netted 292whp and then just switched to 70/30 mix and netted 314whp? if so that seems to be a significant gain in power just due to the meth percentage.

Yeah idk. But, considering that it is 85% alcohol, I don't think there would be any issue.
I realize that all of this is flammable, its just that gas as quite a low flash point and would hesitate somewhat to use it. I would love to be able to use it as my main fuel source though.

ps- my very brief testing, 2 datalogs yesterday, shows me that 100% alchohol does not cool as well as the 70/30 mix I was using. I was showing a total of 50 degrees added to the ambient, where the 70/30 only allowed 25 degrees tops.

no 292 was without any meth 314 was with meth i can do a few pulls to show the difference between 50 and 70%, i did a ton of reading on the gtp, ss, srt, tc and much more forums that Google mother fucker would bring up, all had more experience with meth than we did came to the conclusion 70% was the sweet spot provided more octane and still provided the proper cooling we needed then went to work and did some measurements to come up with this

I found on positive displacement superchargers its helps to have a small percentage of water in the mix. 10-20% water. With it we found slightly better knock control over pure methanol. Keep in mind pure methanol works great too and we are only talking about minor differences when comparing the two.

went somewhere in the middle not too crazy but also against the grain i believe Thomas went 70% after i did, we were working on a calc for you guys its done but he is a busy man and will eventually put up a polished version on his site. :)

Example:
.5 gallon = 64 0z
lets split it 32/32
32 fl oz meth = 32 x 0.05159 = 1.65088 lbs
32 fl ox h20 =32 x 0.0652= 2.0864 lbs

now add 2.0864 and 1.65088 = 3.73728

divide meth lbs into total lbs 1.65088/3.73728 = 0.441733
giving you a 44% by mass mix ratio

meth is at room temp and h20 is at fridge temp (distilled)

Examples:

By mass 50% meth 1 gallon mix = 56 fl oz distiled h20 & 72 fl oz meth
By mass 55% meth 1 gallon mix = 50 fl oz distiled h20 & 78 fl oz meth
By mass 60 % meth 1 gallon mix = 46 fl oz distiled h20 & 82 fl oz meth
By mass 65% meth 1 gallon mix = 38 fl oz distiled h20 & 90 fl oz meth
By mass 70% meth 1 gallon mix = 32 fl oz distiled h20 & 96 fl oz meth
By mass 75% meth 1 gallon mix = 26 fl oz distiled h20 & 102 fl oz meth
By mass 80% meth 1 gallon mix = 22 fl oz distiled h20 & 106 fl oz meth
By mass 85% meth 1 gallon mix = 16 fl oz distiled h20 & 112 fl oz meth
By mass 90% meth 1 gallon mix = 10 fl oz distiled h20 & 118 fl oz meth
By mass 95% meth 1 gallon mix = 6 fl oz distiled h20 & 122 fl oz meth
By mass 100 % meth 1 gallon mix = you got to be kidding me, you fail


above percents were rounded but i can give you exact if you want :beerchug:

H20

fluid ounce (fl oz) 1 = U.S. Weight/Mass pound (lb) = 0.0652

METH

fluid ounce (fl oz) 1= U.S. Weight/Mass pound (lb) = 0.05159


shit...forgot man. I'll get on that today.
thanks bro, when i come down for any meets ill get some 5gallon jugs of meth for anyone that wants me to get some works out to be like 5.25$ for a gallon of 70% mix much cheaper than buying heet

Interesting information there...however I have to wonder what was the TRUE reason for 70/30 making more power. Obviously I have tested that added ignition will not net much more power, so the added power had to be from the added cooling. I know that meth will cool FASTER but not MORE than water. Maybe this is why the 70% methanol works so well. :dontknow:

I was unable to get to the post office today...however tomorrow I should definitely be able to. I dont ship stuff very often so its kind of a new thing for me:ugh:

My tank is almost empty so when I get my new 3 gallon tank I will probably go with your 70/30 suggestion and see how it fairs.
