The dual nozzle kit is 369.00 if my memory serves me right, I run the single myself...havent made any pass with it yet..but on the street 23 psi..no knock(only a little bit on the punch and it disappears in the next frame on the scanmaster)..
Just want to move this to the top because I'm curious as well and would like to see some pics. I ordered a new SMC kit on the GP and wonder if the duals would bennifit me. Car ran 11.73 with 009's and FM. I should be able to turn it up a little more with the 50's.
I do believe that the nozzles are of the same design, just two smaller ones which equal greater total volume than the single. Steve recommended to me that anyone in the 11s or faster would want the dual nozzles. I have them on my WE4 which has the potential for 11s, and on my GN which isn't an 11 second car and they seem fine.
You can bet the duals will be on my T-Type, too, when I get the bugs worked out!
