Searched H-T, didn't find anything on it.

Official press release from VP here: http://www.vpracingfuels.com/s...6.doc

Here's what I've gathered so far from other forums:
Slightly cheaper than C16 but you need to run more of it so no actual cost-saving.
Biggest hp gain claim so far is ~100hp:

Someone else posted somewhere that someone melted the motor running the stuff but it sounds like the person simply replaced one fuel with the other without retuning. Duh!

For those unfamiliar what oxygenation of fuel means: http://toxics.usgs.gov/definit....html

Most obvious first question: Anyone on here have experience with this stuff, either tuning a car running it or running it in their own car?

Similar to switching to E85 from regular pump, the idea is that you need to run more of it because it has a lower potential energy value but the benefit is the motor pumps out more exhaust which helps spool the turbo. The tech press release from them states that Q16 has superior burning speed and makes more pressure in the combustion chamber (as compared to 116 octane fuels)... but is more resistant to detonation because of the extra fuel in the cylinder. So with even more rapid expansion due to heat and faster flame front travel, this to me sounds like EGTs would be higher with this stuff compared to C16. On the other hand, you need to run more of the Q16 (5-6% according to them) and running a little on the rich side is a general preventive measure used to keep combustion chamber temperatures below XYZ threshold (dependent on piston design, CC design, etc.) Next question: Is the general rule that the more oxygenated a fuel is -> the faster it burns -> the more of it you need to keep the temperature in the combustion chamber below the melting threshold?

Moving on... in a thread from back in the day, the following discussion took place here on H-T:

I've never seen the scaling that the above is measured against but I'm pretty sure it's not on a fixed ratio of: "take out so and so much timing for every so and so much boost." So how does it work and from there, how is the scaling changed with an oxygenated fuel that burns faster?

Last question: How is this going to affect people who are maxing out 1600cc injectors and are prohibited from stepping up to twin rails and/or even bigger injectors and/or mechanical fuel pump, etc. Take for example a SFWD B18 setup that clicks off .30 and .40 passes all day maxing out the 4 1600s. Obviously any more fuel isn't possible because the injectors are already maxed. Is Q16 not the answer since oxygenation of the fuel, as I understand it, lowered it's energy density/potential?

Any insights are appreciated

 

Q16 is awesome. Been running it for a while now. It takes a little more fuel than C16, but nothing drastic, nothing like an alcohol based fuel. I know for a fact you can make almost 950whp with 4 160lb injectors on it.

 

same here, i love it. The only thing is the smell. It makes me want to throw up.

 

What's it smell like? Toluene? Race "E85"? Umm, JP-8 Cessna fuel? E98 doesn't smell nearly as strong as some of the "E85" I've smelled, almost brought me to

 

Seriously? I love the smell, smells sweet, almost like candy.

 

how does the Q16 compare to import? i still have mixed feelings on the smell of import. we had a 34? chevy roadster on the dyno today running some odd VP fuel that smelled really good. my clothes im wearing still actually smell like it haha.

 

I've never used Import. Got 5 gallons here i've been wanting to test, but still haven't.

That old roadster probably had a cherry additive or something in the fuel, them good ole boys like to use that stuff.

 

i dont know man, the first time i opened a can of q16 i shoved my nose in the can and almost hurled all over the place. It seems to burn my eyes also, maybe its just me.

 

from what i understand import likes to be ran real lean. going from c16 to import on a custom car i didnt really see any justifiable amount of power gain with increasing timing, and didnt really feel the need to test the lean theory. more or less just did it for the extra safety margin.

unfortunately there were other changes done at the same time, so i cant really say if there was a power gain simply from changing the fuels. i'd imagine there had to have been a little bit.

import seems to be pretty forgiving. friend of mines talon lost an alt. belt going down the track at 50-55lbs of boost. went DEAD lean and survived. who knows.

 

That might partially explain why Import, Q16 and a couple of others have an octane rating of whatever number followed by a +. As I got from the VP tech press release, they have some added resistance to preignition that can't be explained just from the octane rating.

 

we used q16 for IFO this past sunday...made awesome power and it smells awesome!!!!!

I hope thats not how you guys pick the rest of your fluids! "I use corn syrup for engine oil, its tastes like candy!"

From the sounds of it, I'd almost guess they're taking C16 and adding a little nitromethane to the mix, possibly even hyrdazine. A little of both will add burn speed, and help reduce charge temps, and the tetra-ethyl lead does the role of anti-knock. The stoimetric mixture for nitro is 1.7:1, to give an idea of how little is needed to make it a heavily oxygenated fuel...

Whats unusual is the MSDS lists this as 4 for flamability, where the 'usual suspects' like gasoline and methanol are all at 3 or less. They list their additives as 'motorfuel antiknock additive', so no help there. Its also listed as &lt;1% additive, 99% hydrocarbons, so its definately not mixed with eth/methanol.


BTW running oxygenated fuels usually has that trade-off if you're already maxing out your fuel system. But I would suspect that the cooler IAT's and faster burn speed would be a good exchange for volume, since many SFWD cars are going over 40psi of boost and most likely have very high IAT's as it is. They're also spinning past 10k, which the faster burn speed would help. If you complete combustion faster in a fast-moving engine, you can possibly get that much more power.

 

it smell like candy but how does it taste? lol

 

I tasted it the other day when I took off the cap after the can was sitting in the sun, as kinda of erupted out of the can. Pretty good smell but toxic, damn eyes were burning.
