Well I would start here.
FJ = Fuel Jet
MJ = Methanol jet

(FJ - (FJ x 0.15)) x 2 = MJ

Start here and adjust (down size) from there. The right jet size will depend entirely on the whole system design (all pressures and restrictions involved), so they will vary.

 

Thanks for the formula ...

Where did you get that formula from? I would like to read some more on this ...

 

ttt - any new results. i am interested in this for my DP kit on my goat.

 

i do know that it takes 2.2x more meth than gas to run a car.

 

Why haven't you tested out that truck yet?
I'm sure a lot of folks are waiting to hear the results.

 

Currently waiting on getting my ECM back from BS3 having a couple of upgrades (3 weeks now) but it will be soon... very soon..

 

bump for update ...

 

any word flipper?

on my goat i am having a fuel supply issue at activation of my direct port setup. since there is not a good fuel pupm solution for the gto's yet, i am going to go to an external pump for the fuel side of the setup. since i have to do thta, i would rather go methanol/ethanol etc....

 

I have had several delays (imagine that) but again I think I am getting close..

I am also working on a fuel supply issue.. I have an external fuel pump (more than adequate) however I am having issues with the pickup bucket so I converted... Now I am using a high flow diesel pick up and it is running out of fuel also... I am working on a baffle system so that I can use a bulkhead fitting in the bottom of my tank..

I have vowed to make sure everything is perfect before I hit the juice.. My meth sytem is completely functional, pressure is set, nitrous is jetted correctly everything is ready for me to just hit the button, so hang tight I assure you it wont be very much longer..

 

is it having problems delivering the methanol? if you have not hit the juice, how do you know you are having a fuel delivery issue? just curious. i am trying to learn all i can about this. i am actually pretty excited about this setup.

 

The problem is not the methanol its the main fuel system of gas.. I upgraded everything at the same time so there has been a lot of issues to iron out.. Just been knocking them out one at a time..

 

i got ya. do you think that the pump you have for the methanol can push it thru fast enough to avoid that initial lean spike caused by the n2o reaching the cylnders before the fuel?

 

I do believe it will.. it is a return style setup and total overkill.. I am prepared to run a .1 sec digiset time delay on my nitrous if I do have lean spike..
