has anyone use toulene instead of alky in the smc?

[NICKG]

just wondered? this should really add some punch to your engine?

Xylene and Toulene

I'm sure they work fine, they should function about like Methanol. This is the way I look at it.

Methanol: High Ocatne, Less Cooling
Denatured Alcohol: Moderate Octane, Moderate Cooling
Isoprophyl Alcohol: Low Octane, High Cooling
Distilled Water: No Ocatne, Best Cooling

If I goto the track I run race gas with distilled water I have plenty of ocatne to run high boost so I use the water to cool the engien off and act as an intercooler, for street use I just run rubbing alky, because it gives enough alky and cooling effect to run high boost on the street. Xylene and Toulene will in affect give you the octane but not as much cooling. The less water you have in an injected fluid(alky wise) the less cooling effect. So they will be like running methanol.

Both those chemicals will kill the pump in less than a week.

Don't ask me how I know this.

I'll bet you a new pump and bottle from Steve C. if you don't believe me.

On top of that, xylene or toulene are EXTREMELY flamable

i went to a paint store and asked for xylene once, and the guy told me about someone who used xylene to clean something in an apartment with rags. The rags were left in the building, and it self combusted and caused a fire to the building.

so what is the best kind of fluid to run on the street for maximum psi? methanol, denatured alcohol, ispropyll alcohol, or distilled water. if water gives the best cooling wouldnt it be the best to use to run the highest boost levels? everyone i knows uses alky but distilled water is cheaper and you can make it right. when i get an alky kit i want to run the fluid that gives me the best performance and psi.

Water vs Alky

Water is great and yes it cools great! But when you are running 93 octane pump gas and over 20 PSI boost I would make sure u have some octane to back it up, Denatured alky works best for most. If u richen up too much try Isoprophyl alky...

 

[salvageV6]

50/50 water and Denatured. Tap water too.

A squirt of WD-40 too.

 

[blackbuick87]

I believe straight water is a bugger to tune. Too much and instant fouled plugs. Most run somewhere between 50/50 and 70/30

Had any problem with the crud that precipitates when shooting WD40 into water stopping up the screen?

 

[salvageV6]

Maybe. Never looked at the screen.

Had the nozzle plug thought it was due to the trashed pump and some serious crud precipitated out of the xylene problem and pump meltdown.

I'll have to double check the new ones.

 

[Steve Wood]

well, hurry up and go check! I wanta know if that is what is wrong with one of mine!

 

[salvageV6]

You mean a$$ I thought you actually knew something.

Shoulda known better.

My WED40 kinda floats on top like the marvel mystery oil used to.

Never did get that $23 bottle of alky. lube. Prolly cause they never returned my email whether it worked as well with ethanol as methanol.

Go check your own nozzle!

 

[Steve Wood]

I see jelly floating thru the mixture....I figured it was not doing it any good....

actually, I did check the other day and it did not look restricted....

 

[Steve Wood]

the alky lube will mix with straight alky but will not mix with water...have to use something water soluble like RMI-25 or the Prestone waterpump lubricant, I think.
