Alcohol vs. Nitrous vs. Propane vs. Water

Not many worries about propane back firing, I did see a post a while back where a Noz tank blew up and took out a guys garage. But that is very rare.

Propane can help, but Water-Meth injection will lower IAT more and is safer, IMO.

Water-Meth is octane on demand, more HP on pump gas. With our new Injection Fail Safe, IFS-10, it is very reliable.

water/meth/alchy is definantly reliable.. but with propane being a compressed gas, you really don't have to worry about things like pump failures to begin with. Just running out of propane...

also a nice thing about propane is if you want to add more you up the pressure its being forced in at. No need to go buy a bigger pump or nozzels ext.

There is a big difference between the barbecue tank used by our propane system and the tanks allowed for vehicle fuel storage --- eg. fuel flow shut off if the valves are compromised. In addition the tanks are required to be isolated from the passanger compartment as opposed to sitting in the back seat.

what turns on and off your ISG-10 kit? (without using one of your controllers?)

[92stealth15g]

aight, so approximatly how much boost can propane allow you to add? is it safe to run on a stock motor?

[DCIV]

yes safe to run on a stock motor, boost depends on intercoolers, turbos, tuning, and how much propane you want to add. Search up old results from this because there was a following for a good little while.

The ISG-10 is the basic pump system (hose nozzles tank fittings and such)
You need one of the controllers to drive it.

We do it this way so the system is more modular. With all the different mods people have it is difficult to have a complete system. This allows for the selection of the controller that is right for the engine. It also allows for lower stocking requirments for your dealers.

For example the VC-25D is a design specific for the Mitsubishi. But if the MAF is removed for a Blow Through setup, the VC-25 would be all that is needed.

As far as boost I was running 17psi on my stock 9Bs with water-meth. Others on here have run much higher boost with the systems.

Couldn't you just turn the kit on at Xpsi with either an AEM (it has outputs to do whatever you set it for) or a hobbs pressure switch?

What does the controller do that On/Off doesn't?

I am asking because I am starting my engine build to finally mod my VR4 and going EVO3 I want to run high boost (mid 20's) on pump and I figure a good meth kit would allow me to do that. And I am using an AEM so I can configure an output to do whatever.

Its not just an On/Off switch. It gradually adds in meth from x psi to X psi. From what I understand, it adjusts the voltage to the pump.

The amount of intake cooling and detonation control needed at low boost is not the same at higher boost levels. For example: Lets say the car is running 26psi and makes 450rwhp. For water-meth you would need about 570ml/min with this set up. If using an on/off switch you will get full flow at the onset, lets say 10psi activated with Hobbs switch. But at 10psi hp is lower say 300 at that point, so you only need 300ml/min. Injecting 570 at 10psi would be to much fluid and hp will drop some from combustion quench.

The variable controllers regulate the injection amount based on the load of the engine. This allows for maximum hp gains across the entire RPM band.

The controllers actually send a PWM signal out to the pump to regulate pressure. Min pressure is 60psi to get good atomization of the fluid out of the nozzle. As the engine load goes up, so does the signal to the pump to increase pressure. More pressure at the nozzle results in more flow.

Our controllers have been designed to account for the non-linear characteristics of the pump-pressure-flow dynamics. This provide the best possible injection curve for the controller resulting in flatter A/F curves, and easy tuning.

We keep our systems simple for wiring, install and tuning. The basic design is set and forget. Once it is set, forget about it and make the power you want without expensive race gas.
