Default Did some testing on our DF-5 valve.

Well we did some testing on our DF-5 valve in response of a question from a member on one of the forums that we support, so I though that i would share it with y'all.

Would only be worth it if it were a jet limited class or you were out flowing your current valve. (no one on this site will out flow there valve)

Wayne, I run these valves.

Biggest benefit is that with the DF5 youre not going from a small orifice, to a larger ID hose. The only areas where nitrous expands (and goes from liquid to gas) is the head space in the bottle, and at the end of the nozzle. Also, when I add a second gun, I will have more flow with less pressure drop

Yep-, you can see straight though the -8 end to bend in the dip tube.

Thats big.

IMO, its more than most guys on this site will ever need.
Splitting hairs with the more flow less drop deal.

You want to make the extra 35hp this valve makes over the others put another $5 jet in.

the point is you will not see a gain until you out flow the current valve. unless you want to make the most you can with a specific jet its not helping anyone here thats not in the 7's....

Did they ever get the leaking valves issue figured out. I have a friend with two of these and both leaked.

If they are leaking they are rebuild-able if he would like to send them in we can rebuild them for him, but we have not experienced any that were leaking.

He already sent them to you awhile back, not sure how you say you havent seen any that wernt leaking. A few others on other forums had the same issues with the valves. Its a real pain when you switch your car over to run a df5 valve then have a problem, you cant just borrow another bottle from someone.
