whats that qt container that comes with kit, that is pictured on br website

 

Its a lube additive you add to the fuel on oz per gallon to lubriate the pump - it goes a long way

 

I think the conversion of water from liquid to vapor is endothermic, the conversion of liquid r-oh to vapor is also endothermic (yes delta t of the two are not the same), but...the oxidation of r-oh is highly exothermic therby increasing cylinder pressure. It just seems like quelling knock and adding cylinder pressure is going to make more power then just quelling knock. I have been wrong many times in the past is this could be just one more case.

 

That assumes that they convert to vapor equally, and they don't. Alcohol changes state from liquid to gas much more readily as compared to when water converts to steam. The water to steam coversion takes more energy and has a higher latent heat of evaporation. Thus, the amount of heat it being pulled from the cylinder head when water turns to steam is signifcantly higher than when alcohol vaporizes.

Yes, that is what I was thinking (whew it's been fifteen years since physics)! My point is IF you are able to quell knock and add btu's with the alky (as apposed to just quell knock with the water) it has to add cylinder pressure. Now, if the water can remove enough heat to allow additional timing (over 100% alky) then it is possible to make more power with water, but if all things are = then the alky HAS to add power (which water can never do). I think

Also, adding more octane (which is effectivly what water does) only adds power if you can decrease knock, increase boost, or increase timing. Latent heat of evap for h20 is 970 btu/lb, r-oh is 385. So yes it is higher and will cool more, but if you don't need that much cooling and can get by with 100% r-oh I still think it is going to make more power.

 

There is no doubt that the alcohol makes more whp because with it you can cram more fuel to be burned at a richer a/f and making more power. If you try and run 100% gas at that rich a a/f it will loose whp as the ideal a/f ratio for boopsted application on straight gas is 12.5 / 1 a/f. With a hybrid mix of 20% alcohol the ideal a/f is much lower - prob somewhere in the 11 range allowing tyou to run into the 10's and still be making peak power.

 

Enough theorizing. Someone get on a dyno and compare water to alcohol! That'll be the proof. And that's coming from an **** engineer

 

As a **** engineer do you work for Real Doll? Do you use finite analisis modeling software?

 

I don't quite get your "Real Doll" comment, but yes, I do work with FEA software almost every day. Not sure why you ask.

 

LMAO !

 

 

Apparently, my mind isn't in the gutter as much as you guys.

 

Hey 4ring...u get a chance to run the car yet? Im still waiting on the new numbers!

 

As an **** engineer,Could you please comment on the quality of the lube provided with the alcky kit???? LOL

Also how often do you recommend we use this lube???? LOL



he said **** LMAO

 

LMAO!!! Alright lets all grow up now LOL
