I'd go water injection, you hook it all up, and bada bing, you've got free injecting fluid (water), b/c tolulen isnt cheap, but neither is alcahol, but at least with alcahol the spray unit will only be actuated when you are above a certain boost level. Howevwer, water is the cheapest way out of it.

 

You know, I really like water injection .. the only problem with me is its failure variable.

If you tune for having WI necessary, and something fails on the WI, and the fail-safe systems don't know about it, I better have about 3Gs in the bank account to replace a failed motor.

Sadly enough, the $500.00 WI initial cost, plus tuning, plus some extra in the bank, just isn't quite feasible right now.

I'll pay a bit extra for toluene right now, but still tune for 91.

hmmm, haven't heard of it failing before, maybe if you run w/o water in the tank, but most sophisticated versions have warning lights. Also you might want to take into account that on a long period basis tolulene w/o addatives will eat at your fuel lines/pump/etc... that is going to be a certain cost issue, but much more just a pain in the butt to replace all those hoses, and your pump and etc.

 

Looking at this from an engineering prospective, there are about four main variables in a water injection system,

1.) the Water itself
2.) the Pump
3.) The Electronics, and
4.) nozzels and tubing.

If any one of those would have a failure, you'd get no water in the system, and may have such an agressive tune (for the reason of getting WI anyways) the motor could get enough hard detonation and go boom.

But that's the risk we all take when we mod the EVO (or another HPerf car) anyways.

Without risk, everybody would be doing it, and it wouldn't be any fun.

So back to the critical thought avenue:
1.) Is solved easily enough with sensors for visual indication
2.) Could be detected with well designed electronics
3.) Could really hose things
4.) You'd never know unless the electronics were smart enough to try to figure it out.

So .. in all you really do get what you pay for when you purchase a WI system.

On Toluene:

True about being corrosive ... Toluene is a solvent for a reason. The combustion trick is to run it lean enough to keep it outta the oil for any length of time.

I'm sure a 10:1 to 8:1 mix is probably still safe enough to let the additives already in the gas keep things nice. Also, gas, if left for a long time without Stabil or something, will rot stuff as well.

Ahhhh .. the nice smell of terpentine.

Good thoughts dood.

P.S. I've got one supercharged friend with Wi, and he's run about 40k miles with absolutely no problems. Then again, he bought a Jackson racing version and really got a nice setup.

 

cool, yea I was thinking BR, since his products are really paramount for our cars... It is meant for alcahol injection, but I would guess that you could run water, or at least with very few modifications. I would think that with this type of injection system (with sensors that let you know everything that is happening in the tank) in combination with tapping into the knock sensor in order to keep that monitored, it would be as safe for me as getting my dyno flash was. I agree, both have drawbacks, but to me it seems more intelligent to blow 500 once rather than 10 every 2 weeks, plus the trip to and from the store (time and gas) Not to mention the alcahol/water inection system has gives way for future growth, say if you up the turbo (boost) and want to take her to the track under say 27 lb, your still ok, rather than trying to figure out if you need to bring 10 or 20 dollars worth of tollulene. anyways, I like tol. for a quick jolt when I know something is comming up, but for daily purposes, I'd go injection because of the expandability thereof. Good stuff from you too bro.

 

You know, with all things considered ... for a daily driver, I think you're entirely right.

Another political factor in Toluene / Xylene sales is I know if you start buy large quantities of it you can get the heat on ya because they may start thinking you're producing meth. That sux.

It almost seems that the fun chemistry sets of yore, when I was a kid in the 80s, need an chemistry association license or something.

Random thoughts,

I am a paint contractor, and when I bought my gallon (mind it was the first one I've ever bought... you dont really use tolulene for anything practical) and I have had an account with sherwin williams for a long time, they know me well there, but guess what? When I bought this gallon (all by itself, no other supplies or paint) they said that they were bound by law to ask what I was gonna use it for!! They told me about how much of a thing it is around here and trying to stop crystal meth production. These guys saw me every day too! heh, oh well, I told em it was for race gas for my car and they looked at me funny for a second and said eh, ok. So yea, it does definately attract attention.

 

anyone know where to buy fuel cans... and anyone wanna do a group buy in southern california for this stuff?

 

I went to shernan williams and bought just a gallon of toulene to play with. Do I mix the pump gas before pumping it into my tank or can I just pour it in on top of the gas I already have in the tank?

 

Bump

 

pour right in. btw if anyone ever wants any... pm me i'll be getting a 55 gallon drum of toluene.

 

Thanks. How much for each gallon?

 

if you want to buy from me? i'd prolly sell for 3-4 dollars a gallon which is cheaper than anything you can buy at the store... (except a 55 gallon drum)

 

Sounds good, Im going to play around with the toulene this week and get back to ya.

 

yea man, Ill keep you listed... shipping is pretty impossible thou....
