The comments from other racers range from, very happy to cautious. Everyone seemed to gain horsepower or got quicker times. Everyone had to jet up (approximately 4 %) in order to take advantage of the benefits of the oxygenated fuel. Timing does not have to be changed.
Some people experienced deterioration of braided hose when they failed to follow VP’s instructions to drain the fuel after each day at the track (These instructions are on the drum or can that the Q-16 is shipped in from the refinery). Others have flushed their lines and left C-14 or C-16 in their fuel systems, if they run every week.
In the past, I have had to replace two set of braided fuel line when I left them dry over a 4-6 month period. And that was using regular racing fuel. I have been told that braided line does not have a shelf life until it is used. Then it starts to deteriorate, and sitting with nothing in it will accelerate the problem.
There are warnings about storing the Q-16 fuel in plastic jugs (like I just purchased). The Q-16 loses it’s potency when stored in plastic jugs or fuel cells, which are vented by rules. Most racers feel the extra work is worth the effort (and cost) to get the quicker times and higher horsepower.
So, be very diligent about obtaining all the information you can get before using VP Q-16. Follow all of VP’s warnings and recommendations.
In my case, since I have slowed down to around 9.13 – 9.18 in the quarter (Summer heat), and I need to run 8.99 to get into Top Doorslammer. It may be a good solution for me. I think 20 – 30 HP would get me there.
On the other hand, I have a lot of time and work tied up in the AN#10 braided hose that runs from my fuel cell to the fuel regulator at the front of the engine. It would probably eat up the foam in my fuel cell too (if I let it sit with no fuel in it). Tough choice. I can always run Super Pro, Super Rod, Hot Rod, Super Street or Super Gas. I will have to wait on the <72 degree weather to run Quick Rod or Top Doorslammer.
This reminds me of all the work that Jr. Dragster owners, running Alky, have to go through when they get home. Jr. Dragsters, running Alky, are more work than the big cars, in my opinion, but it’s worth it for the kids.
