Injecting Totulene with Extra Injector

[smokehouse_83]

I kinda have an idea. What if you took a small aftermarket fuel cell, put a stock fuel pump in it, and ran a fuel line to a single injector lets say in the throttle body elbow. Then injected Totulene, a octane boost that is very safe(ingredient in gas), into the engine using a pressure switch set at like 12 pounds of boost. It would be almost like water or propane injection, but much safer since its kinda part of gas. It would allow you to run higher boost on pump gas since it would be like running higher octane gas, you would also save money by only using the totulene under boost instead of pouring it in your gas and blowing it all in one tank a gallon jug of totulene would last awhile. Of course you would probally need an afc to lean it out and a dataloger to watch what its doing. I am guessing most people already have a stock fuel pump and an extra injector laying around so all you would need to buy is a fuel cell(get one of ebay cheap) some fuel line(which you might have too) a pressure switch($25) and some other assorted parts. You could probally throw this kit together for well under 100 bucks and its much safer then water injection, the worst you can do is run way to rich right? What are your thoughts?

I would use a water tolurrine mix that would be best. Great idea though, many tt mustang homemade sytle use an extra big injector hooked up to a pressure switch to activate extra fuel since there is no piggy back computer that is affordable for them.

How are you planing on regulating the amount injected? Or are you just to turn it loose wide open.

At some point you should think about being able to turn up the boost efficeintly. Some ideas might be a more efficeint intercooler, a turbo with a compressor map that efficeintly makes the boost pressure you want, without adding to much heat. A fuel management system that allows you to control your air fuel ratio more precisely. Just a few ideas.

Since the AFC alters the injector pulse width at certain preset RPM points, and you have your AFC set to lean things out( for your tolurrine injection system) say above 4000 or 5000 RPM. What is going to happen when you are at 5500 RPM and not making 12psi of boost?

one thing you need to worry about is puddling in the intake manifold. the same problem on a nitrous setup can result in explosive fires. i think there are better uses for toulene, such as adding it straight to the gas already in the tank. water injection or a small nitrous shot might be an overall better solution for you.

Wow talk about bringing an old post back. Anyways, I have a meth kit and was wondering why toulene would puddle in the intake manifold more than methenol? I believe toulene has a higher octane rating than methanol so would you be able to make more power with a toulene mix as opposed to a meth mix? Just wanted to know if there were any more pros and cons to running a toulene/water mix instead of a methenol/water mix. Thanks!!

Toulene certainly has a higher octane number than Meth and is MUCH less prone to detonation. However, it does not do even half as good as water in cooling the combustion chamber and intake air down prior to the power stroke. Meth does the best in cooling for the alcohol family (as I've researched; there may be something I missed). This is the advantage to water or water/meth injection over injecting just an octane booster. Water injection alone has been known to raise pump gas octane levels to 110 (indirectly, as it slows down the burn to the same speed as 110 octane gas). A meth mix seams to lower this final octane number but has the advantage of cooling the air charge better becasue it breaks into finer mist particles. This gives it more surface area to absorb heat fast. Even though it absorbs less heat, it absorbs heat more rapidly. 110 octane: do you need a higher octane number??

An on top of that it has a much higher specific heat, or the ability to absorb the heat; most importantly taking it out of the combustion chamber and, in addition, taking it out of the air charge goin into the combustion chamber.

Water and Tolulene dont mix. They separate. Water mixes with methanol.

and as for "safer" than water injection? How is that possible? You get a leak ANYWHERE in the toluene injection setup and you have a possibility for a huge fire.

Get a leak in the water injection setup and well, you have a puddle.

If you are referring to making a the engine hydraulic, well, thats just not going to happen, if you are even close on nozzle size and setup. With a crack pressure valve in line, its almost impossible. I have dual nozzles in my setup and its like 2 plant misters, not that much water really.
