Agree.... I think q16 burns a lot hotter in the pipe...... but the plugs dont show much heat.... You better not be scared in october 50 degree evening qualifiers, if you dont run better than you have been, gonna be disapointed.....

lol, i surely wont disappoint.

So it is corrosive? What's the maintanance like? I noticed that it burns a lot more fuel as well. Wanted to know because I haven't used C16 and was on Torco's 118 last year. I did notice a difference in power this year with the Q16.

I been sticking with my 7$ a gallon 112 Sunoco.

Buddy of mine runs q16 in his evo... loves it and made more power on it than c16 on kill. The only downside he saw was you have to run it through pretty quick and not let it sit a whole lot like everyone else is saying here. Price was same as if he ran C16 basically so why not make more with the oxygenated fuel.

Yeah , I run my under 6.00/gallon sunoco 112, mixed with some 91... for my junk.

[eg:R]

what is the target a/f for e85?

[bads2k]

so with id1000's or id2000's should we stick to c16 or is there a better fuel to use then c that we can use with those injectors without worrying about the corrosion that the q has

[Bugermass]

We run Q in the RSX, AFRs are 12.8s.. I'd go leaner and see if it picks up power but we still have 25 more PSI to go and were already breakin the 26inchers loose in 3rd @ 30PSI.

Q16 and VP Import causes the valve to swell, restricting flow. They car compatible with every other fuel we've tested to date. If they are run on either of those fuels, they come back to normal after airing out for about 48 hours.

We recommend C16 or C23 for really high hp applications.

Let's be clear if you are going to quote something....

That ONLY applies to the ID2000's

NOT the ID1000's

I run 8x ID1000cc's in my car on Q16 and have not had a single problem. The car hasn't seen full power yet, but it will soon.... that shouldn't matter though.

I don't know if the Bosch pumps like it though.... I guess only time will tell.

[jdm inc]

yea i forgot to put that. it only applies to the id 2k

[B18c1turboedEK]

What happens if you mix c16 with q16? but you where tuned on straight q16?

[locash]

Dont mix fuels, if you change fuel, retune. Simple as that..

[bads2k]

i don't even know if i can get c23 around here. How much is it for a 5gall container?

Damm i guess that was what was making my car miss really bad on Sunday... Guess ill drain it all out now...

[miller]

If you are going from q16 the only way to go is up and that is to import. That is if you are willing to spend the $25 a gallon for the import fuel.

In going from the q16 down to c23 you will gain some octane rating but you are losing the important part and that is the fuel being oxygenated. That helps in keeping detonation down. The fuel being oxygenated helps in the atomization/vaporization of the fuel.

agreed, but then again, a fuel with a oxegenate in it, in reality is a octane booster, which in theory raises the octane to, in lab terms 125-126 octane, so i guesss ur not neccessarily stepping down to 116 octane lol

I see what you are saying but SG (specific gravity) has a major play in alot of how well a fuel does also. I would probably most likely go with the c16 over the c23 seeing as how both are non-oxygenated fuels but the SG of the c16 is .73x and the c23 is .70x. That is a huge difference in itself. That is most likely the major reason as to why c16 was such a succesful blend before the q16 came along.

[GT30EK]

Where is everybody getting there Q16? I live in NY so they dont sell it here. I call like three places in NJ, and they all said they were sold out and it would take 3 months to get. This was in the summer, thats why I still run c16.

[vtekthis]

they lifted the rule about 3 weeks ago for the sale of MTBE fuel in NY, i know SK speed has it in stock, and im sure any other VP dealer should be able to get it aswell

[miller]

Darren(gt30ek), I have it in stock but not in 5 gallon pails. I jsut recieved 2 55 gallon drums late last week.

What affect does SG have on performance?

[miller]

Are you ****ing with me or do you want to see if I know the answer? Either way. Here is my answer to your question.



Fuels that have a higher specific gravity number have a higher resistance to detonation.

Import has a sg of .744 and is oxygenated, q16 has a sg of .716 an is oxygenated. C16 is not oxygenated and has an sg of .735. Now c23 is not oxygenated and has an sg of .713. C23 is the lightest of the group in question and is also not oxygenated. I am in no way saying that c23 is a bad fuel but why would you choose c23 over c16? Based solely on the octane rating?

The reason for this is that the fuel will i guess you could say "fall" faster, the faster the fuel falls the quicker the fuel gets away from largest concentration of heat which is the the top of the cylinder or other wise known as the combustion chamber.

In turn cold is denser than hot air so it falls where hot air rises.

[tony1]

I'm not f*cking with you. I have never seen a correlation between SG and resistance to detonation. I thought octane rating was a fuels resistance to detonation?

What about C10? It's SG is .763 and octane rating is only 104.

There's more to choosing a fuel than octane, but i've never heard SG being one of them unless you're trying to maximize fuel flow through a given injector/carb jet.

Good to know miller, I'll just bring my jug over. Looking to make some small changes this winter.
