Why no alky?

[vacuum 6]

Dont get me wrong I love race gas but two reasons I will never go back...

1) too much $$$$ these days

2) I'm using the stock ECM and leaded fuel and O2s dont mix

I got a source for alky...about $2.75/gallon.:smile:

I'm an alky now and forever!

Where's your source at? Is it Meth? Let us IL. guys in on it.

Anyone that sells VP racing fuels, ie C16, should carry the 5 gal cans of Methanol for around $25. HTH

We had Julio's kit installed in Bowling Green and after a few "shakedown" runs on the street, we ran a 10.71 without adjusting anything, running it just like I drive the car on the street! I ran 21 lbs of boost and had zero detonation. When I get familiar with the system and crank up the boost I feel solid 10.40's are realistic on a good day. My car is a street/show car with closed exhaust, AC, DOT tires, and it kind of looked out of place with the race cars in bracket 1 in the staging lanes. Thanks to Julio!

I know where to get meth. But he said, a source for 2.75 / gal.

Well, I would up leaving a message at PGH Raceway and the track manager called me back, said I could stop by anytime. Frank Tedesco, real nice guy. I ran up on Saturday and picked up 5 gallons at $4 a gallon. Beats the Hell out of $14 for denatured !!! This should last me the rest of the summer. I only drive the car on weekends for the most part, so I suspect 5 gallons a year will do it for me

Back on topic...I kinda figured there wouldn't be a lot of people posting about why they don't choose to use alky. It would be like provoking a Bee hive with a stick without using body protection. :wink:

Very nice times, that has to be a fun street car. :biggrin:

Julio installed the dual nozel on my car friday morning @ the Nats in like 3.5 hrs. After that we more or less made 3 runs on I-65 re4cording with the DS and on the 2nd run took out fuel and on the 3rd it was dialed in with no knock all the way across the screen and 02's 770-780 @ 26 lbs of boost . No kock on scanmaster or on casper's visual or audio gauge or DS.

To say I like it is a understatement. I bought a drum of VP M-1 for 140 bucks.

Of course then I boughthe new 4" maf pipe and my tune went to hell but thats another story and was fixed by putting my old set up back on.

I too put off buying alky for years. I did not mind paying $4 for 110. But now that it is close to $6/gal now, I bit the bullet and got Julios kit. I got a TT chip too. The car was pretty much dead nuts on as soon as I installed it. I hit 26lbs of boost and no knock. I liked it so much I bought another kit for my GN. :biggrin:

 

[Adam Connell]

Im broke... does that count for not buying the kit??

Also the car always needs something else... Seems like everytime I scrape together 3 or 400$ to spend on the car something needs fixing or is bugging me enough to fix it instead or I find a good deal on something else... last month I had the power antenna shaved because I got so sick of it breaking and jamming.

This months $$$ is going to a new down pipe because I found a killer deal on it... Alky will be on SOON though. Im still learning these things so Im still nervous about the install and tune... Im happy running at 15lbs on pump gas right now, but yes I have felt the difference alky makes and how much better everything works at higher boost w/race gas... I can only imagen 25lbs of boost

The primary reason for alcohol injection, which nobody has mentioned here yet it is cooling, not the air per sey ( which it does ) but for cooling of the cylinder temperature to prevent detonation. When running high boost on pump gas the cylinder temperature gets high enough to light the air/fuel mixture prematurely ( which we all know is detonation ). When alcohol is injected in that situation, the alky lowers the cylinder temperature to keep the fuel from flash igniting allowing you to run more boost than you normally could on pump gas. As far as alky being an octane booster, that might be semi right, but most say that 93 and alky together would be the equivilant of 108 octane. One thing that alky does not do is add extra oxygen content. You could say that alky/meth injection could be thought of as a knock/detonation suppressant, which is exactly what it does. If you have alky and an EGT meter ( not the dial versions but a digital handheld or if you have EGT hooked to a TPro or so ) watch the EGT's next time you get on the boost and the alky/meth comes on and watch what happens before and after the alky comes on. Or hit the test button while driving. I've seen my EGT's go from 1200 or so while cruising and push the test button and the EGT's will drop 350°

So alky allows you to run more boost cause it is a cooling agent where running say VP116 allows you to run more boost cause it is a higher octane of fuel. Not to say the both are the same but we are doing the same with both. Well saying its equivalent to 108 octane kinda mokes me want to turn the boost bacl a lil bit !!

Thats the whole thing, they basically ARE doing the same thing. 116 suppresses detonation and so does 93. The reason the alky has a higher resistance is that it just does not want to combust... the energy alcohol puts out is about half that of gasoline when combusting. The stored energy in the alcohol is MUCH less so it really does not want to pre-ignite as easy... The reason why alcohol engines put out more power though is because they dump a TON of fuel in there... thats why a methanol injector may be 165lbs where a 65lb injector may get the job done for gasoline. It takes less gas to produce the same energy.

Kind of unsafe but go take 1/3 cup of gas and 1/3 cup of methanol and pour them on the ground and light them at the same time.... feel which one puts out more heat... thats the same thing thats going on in your engine.

I wish I could put it into exact terms but here is what alky does:

-raises the theoretical "octane" number
-majorly cools the cylinders(egt shows this)
-also cools the air charge because of evaporation
-cleans the top end of the engine

all of this together REALLY suppresses detonation as shown by everyone's results... Alky does not do ONLY one thing, it does many.

I wouldn't worry about pulling the boost back, the 108 isn't written in stone considering you can always crank the pump speed up spraying in more and add more fuel which would throw the 108 out the window. I mean you can literally drown a motor down with alcohol, so you could run it right on the edge as far as that goes. I run 26psi and 23° timing on the street at all times with just a SCM progressive kit, no telling what I could run on Julio's kit.

But to what you said first, yes. The akly/meth acts as a cooling agent to reduce cylinder temps keeping them low enough to not flash ignite 93 octane under higher boost, which of course is why you can run higher boost with pump gas. And 116 being higher octane makes it harder to burn and harder to flash ignite. So eventhough alky/meth and race fuel are different in their own right their purpose for the end result is the same, just going about it in a different way. Like the old saying goes, there's more than one way to skin a cat.

Well somehow Julio thought of that and installed a switch called "On/Off" so you could actually turn off the $5 a gallon expensive methanol injection system and run you 8-15 lbs of boost.... or you could makes adjustments so it doesnt spray untill a certain boost level, and you could control how much alky it sprays at what boost level. Thus increasing the alky as boost increases. But alky does have a few draw backs no one really mentions.

For example. You are able to run more boost (around 18-25lbs) which means you will probly waste more gas too and increase the chance of getting speeding tickets. That sucks!

Also it causes excessive smoke and noise coming from the rear end when accelerating hard. I think it comes from the tires breaking loose all the time but I have yet to prove it.

Another thing (might be related) is the rear tires wear out a whole lot faster than before. Im guessing cause the added weight of the alky system but Im just speculating.

Last, just like drugs, its addicting. The more you hit the gas and the more you want to do it over, and over again. It freakin sucks! Then when you accidently install a BstC Boost controller and run as much boost from the seat of your car as your want, forget about it. Makes you not want to drive the car anymore!

Installing alky, worst decision I ever made!....... did I mention I might be dislexic?....

Dude dont get alky! Let the rest of us have all the fun!

LoL, best post ever

Crap I missed that post. That is a good one LOL.
