Running a dual fuel system for a build and trying to get a idea of how much fuel i will need for the meth for 700whp.

Have 750cc primary system and 210cc secondaries.

 

I'll be honest. You're one of the few that would use a primary/secondary fuel system and not be a rotary engine.

We usually run a turbocharger large enough to make about 700whp anyway. We just use enough to keep the AFRs low enough to keep detonation at bay to make that power. Sometimes it may mean using 1 gallon or 5 gallons. Depends upon the size nozzle of methanol, and the concentration of methanol used. Some use washer fluid, others use Liquid Heet, isopropyl alcohol (propan-2-ol), or just damn near anything that makes up the formula (CH3OH – is four parts hydrogen, one part oxygen and one part carbon).

Unfortunately, unlike E85 or VP fuels, there's no real consensus as the exact formula to use with a two stage fuel system.. So, all I can say is YOLO.

 

Lol i figured it was worth shot, maybe no one just talks about it and its a big secret. If i had e85 local i would go that route, but this this is my best option.

 

Oh no. It's not a big secret at all. It's just that there are so many possible combinations, that it's really just not discussed all that much in detail to create any big standard outside of the "bolt on" versions from Snow Performance, AEM, Devil's Own, or Aquamist. Especially for Honda guys. You go to a SRT-4, DSM, Turbo Diesel, Rotary, or Ford Focus/Fiesta ST forums, and they get into more detail (you're still the only one that would use primaries/secondaries on a piston street car, no kidding).

But it's no secret. It's just that most young Honda Thundercats (especially nowadays) just get on one bandwagon (called E85) and ride that bitch 'till the wheels fall off!

 

Im going to go check the evo forum and see how 20gph works then. Just trying to get a idea for a starting point as well as figure out what im going to do for a fail safe.

 

Im on the same route but to save the stock b16 from exploding.But using a simple single nozzle setup with 50/50 mix with water.
Pure meth gets a little bit difficult to make a kit. If you want to run 4 nozzles reliable lines must be manufactured
because the fluid will be flamable.The problem imo is controlling the spray.
There is a kit 30-3350 that controls the amount of fluid sprayed by injector duty cycle and not just by boost and i asked aem for some extra data.
They unswered that this kit is for NA setups.Ill send them a second mail today to ask them if eitherway can be used for forced induction setup witrh the correct nozzles.
So ill report back.

I HATE the idea that the same amount of liquid will be injected once you hit full boost till the redline on the normal kit.

 

Whether it's 100% methanol or a 50/50 mix, the kit is still essentially the same. Most of the "50/50" kits that are used here in the Upper Midwest are running darn near 100% all the time. Like you stated, the progressive controller is what seems to make or break a system.

 

My Mustang and I do not like methanol. My honda and I are securely on the E85 band wagon.

 

My honda LOVES methanol. Like I said. many ways to skin a cat. Just because the mustang died, doesn't mean it's from its use of methanol. LOTS of factors have to be taken into account with any tuning fuels, even E85.

 

Just saying most people use a kit like AEM or snow etc... If the pump locks up like in my case etc.... it sucks.

 

I'm using a edelbrock performer x secondary fuel rail setup with a 044 and 1.5 gallon fuel cell in the factory batt location.
