Okay, not to be any one manufacturer specific, but there are different versions of progressive kits, meaning the signal used to determine the amount of meth to inject. For example, MAF based versus pressure. What are the pros and cons of the different methods?

 

What kit would be best for a SS/TC daily driver with full boltons and occasional highway pulls and runs at the drag strip?

 

What size nozzel are most people running on the ss/tc?

 

I have ran both 330cc/min or 5gph as well as 550cc/min or 7gph nozzles on mine before.

Im built with full bolt-on, pte 5857 turbo, e47, and devilsown meth injection on a 7gph nozzel thinking about upping it to a 10gph

 

I have all the usual bolt-ons (dp, Ic, cp, ex, It, stg1+tune). I have a stage 2 AIS kit I'm installing and just noticed the nozzle that came with the kit is a 2gph. Should I start with that or just order the 5 or 7 now to start with. Seems a bit small...

 

What about running E85 through a meth kit? I think it would be beneficial for the fuel system as it wouldt be maxed out like it would be running full E through the injectors.

 

go with at least a 5. if i were you a 7gph

dont do that as the system isnt designed for it nor would u benefit from the cooling aspect as meth. Either 93 and a meth setup or E85 in the tank period

 

Just ordered the 7!! Thanks

 

7gph will be fine, thats what im running or was running im pulling my progressive kit off going to purchase zzp's 5th injector kit... Anybody interested in a devilsown progressive kit hit me up

 

What the advantage of the 5th Injector kit if you already have a meth kit?

 

You can run more timing on E85 and it still has similar cooling effects to Meth, how is the system not designed to E85? Would it not be enough fuel volume?

 

Because I need more fuel... Im running a 5857 right now I have no issues but im going to go full e and I would need the extra fuel from the 5th injector and I want to turn up the boost

 

Oh yeah I forgot you were big turboed

 

I would think a Meth injection system would run better spraying E since its a little less aggressive than Methanol on parts like lines, gaskets etc. Costs more though.

 

Ethanol is also a dirty ass fuel. I would not run it in a meth system

 

Yes it has similar cooling effects and meth as far as combustion and egt temps are concerned. It however will not cool your intake charge down as its the water in the meth mixture that does that. A meth system and pump isn't designed to run e85 through it. But he if u like be my guest

 

Please explain this comment.

Also, it's the atomization of the liquid in the charge pre throttle body that cools the intake temp regardless of meth, ethanol or water. They all posses the ability of decreasing temps. The water is in the meth mix for safety reasons as well as to decrease its extremely corrosive effects.

 

I just did a little googling on it and some of the more common answers that keep popping up is the fact that e85 is more corrosive and could eat away at the pump seals and such. Also another good post was on ls1tech which posted this.

It would help some, but not nearly as much as pure methanol. Gasoline is stochiometric at about 14.7/1, ethanol at somewhere around 9/1, and methanol at around 6/1. This means MUCH larger quantities of meth can be sprayed without overly richening you fuel air mix. The larger quantity of meth means more cooling effect, which is the whole point to begin with.


The common concenses is to stick with spraying Meth and running e85 ( or mixture of ) in tank.

 

That's what I have been getting at this whole time if u guys would listen.

 

Ethanol pure e 85 is known for clogging fuel lines injectors filters etc. Esp since our cars were not designed to run it. Go ahead and put that in a meth tank setup with smaller lines, smaller screens and nozzles and see how well that works for u. I have also experienced with 100% meth and with more of a water mix. 90% of your cooling is coming from the water not the atomization of the meth or other fuel.

 

If that's what you were trying to say, you woulda (shoulda) just said it.


I'm not gonna pretend to be a chemist but I have probably a lot more experience with Methanol than your average person. We use it in extremely large quantities (along with tons of other solvents) in the chemical processes we do at work.

I will tell you point blank pure methanol will cool far better than water. The stuff boils at room temp. Faster evaporation means that it is consuming latent heat energy at a higher rate than water as water evaporates much slower. Now perhaps you experienced better cooling with water bc you could not pump the methanol fast enough for it to work better. I dunno bc I don't use it but that could be why in a meth injection system where over spraying is causing tuning issues. Again, I'm no chemist (or tuner) so I don't know.

If you ever find methanol pure, squirt some on your hand, let it evaporate and them use a temp gun on your hand. You'll be surprised.

I have never experienced any problems with E85 clogging anything. It's held to the same regulations as gasoline as far as I know. What you may be referring to is the fact that people have been experiencing precipitation of solids in their fuel system after using E85 mixtures. That's not the E85 being dirty, that's the higher ethanol content reacting with crap in the gas tank of some people's cars. I believe a lot of DSM people have experienced this.

Either way, I agree, should obviously spray meth in a meth system but you *could* spray E85 and it would benefit in some way.

Lastly, whomever said Ethanol is more corrosive than Meth was definitely smoking the good stuff that day. Ask any chemist.

 

I also want to add, just to clarify, that without any atomization your system would not work. Period. It's the fact that the water is atomized that allows it to cool at all otherwise you would be wasting your water and hydrolocking your motor.

Kinda like how at football games they have those fine mist fans behind the players in the summer. Same idea. They aren't showering them bc the mist actually cools much better bc it evaporates so fast.
