I have been thinking about trying some q16 fuel. From what I have read, the more air starved your combination is, the bigger return you will get from it. My motor is probably about as air starved combo you can come up with. I am looking for tips, tricks, etc. to get the most out of the switch. Currently I am running c16 which is probably overkill for the motor (all cast iron, 13.5 comp), but the cranking compression is around 250psi so I just want to be safe. I realize I have to jet up, but read conflicting information on how much to start with. What is the target a/f? Same as normal gas? What about timing? Does it HAVE to be dropped? My motor likes pretty low timing but getting it so low kills bottom end tq (may put on a programmable box). Sorry for the long post. Thanks guys Work In Progress- 71' Duster F.A.S.T.- 10.36@130 Smallblock Record Holder.

No way is it the correct fuel for your combination. If you wanna try oxy fuel.....with your CR, VP113 may be a better choice, possibly C12, or C14 in non-oxy.

I've tried it in lower compression engines without much luck. In my 514 it worked pretty well, but that engine has 15.5 compression.

I guess I won't know which one works best till I try them. Too bad you have to buy it in 5gal cans. Wonder if you could mix them?

Well that's encouraging. It would awesome if it would give me a tenth. Of course, the more hp I give it, the harder and harder it is to get it off the line.

It works...Aside from being a VP fuel dealer, I have many dyno tests to prove the fuel does whats its supposed to..I have been using it since it first came out and worked with a VP engineer on getting up to speed on running this fuel safely and effectively. I have also recommended and worked through several other combos for friends and fuel customers that have run their best times on the Q16. These guys swear by it now.. There is special handling invoived..Jetting is important as is timing. Also some other more mundane stuff. It is an IDEAL fuel for FAST type engines..Many of the records set might not even have been possible without the oxygenated fuel. Call me if you want...I have a lot of experience and R & D with this fuel. It will work for you. MB

Trying to break the 10second barrier in FAST form. That is so cool I can't stand it!!! If the Q16 can give you a tenth+, that would be sweet. Good luck with the hunt for 10s.

There is NO Magic jet number for making the switch. VP will tell you 5% more is a good starting point. We have found some combinations have taken up to 10% more. IN my car it was about 8% more jet and a lot of bleed work. As for A/F ratio we have seem to make the best power at 12.6 or so in my B1 and the Pro Stock 99 Hemi I have. That has also been close on every car we have worked on. It will take quite a bit more fuel to get it there over a conventional fuel. Another option might be C25, it is expensive but it makes power too... "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

You don't have the luxury of adjustable air bleeds and unlimited jet sizes like a Holley. Be sure to drain the carb after every race. That Q16 might turn the TQ into jelly if you leave it in there too long.

And draining it out of the car is a must. Eat up my accellerator pump in about 4 hrs. One thing that did happen when using it is at about the 1000' the engine would feel like it was running out of fuel for a split second and then come back to life? This happened every time with the Q never with c16 I don't know if anyone else has had this issue. Maybe HP Mike can make a track visit we have not seen him in a while? Ed Cook

As far as the running out of fuel situation, I had the same thing happen and the cure was changing to a bigger needle & seat to allow more fuel into the bowl.
