Brandon Lawlor and myself spent all weekend testing.
I tore down his dasa 1k and installed a PHP light weight crank, MSD, and made a few test pipe changes to go with 3 different water box designs.
As of right now with a different stinger design we went from a 7-13 to a 11-16 prop and we are still spinning the 11-16.
Have a couple more engines to test the new stinger design on before we can release it to the public.
But as of first tests it looks like we have found a large gain in the v2 and V3 pipe.
The new stinger also makes the different water box designs very difficult to notice any gains in all three designs even with TL and 230psi comp.
you can also run the pipe warmer for better mid top with less bottom end sacrifice.
But like I said we have only tested this as of know on a TNT SETUP DASA 1k.
Motor specs. Standard DASA port timing, all the port tunnels have been heavily modified and epoxied in places, cycle cross drilled for better cooling on intake side of the cylinder, TNT reshaped domes and squish angles.
MSD with 34 deg static timing retard starts at 4800 pulling back to final of 13. Running 80/20 pump gas c12 mix at 32to1.
Stock 46 carbs with TNT mod transition ports and back bored. 130 low, 125 high. 2.3 needle seat, 115 spring
H20 155 pump 92mm reduction nozzle 96mm steering nozzle
RRP scoop grate in a FFF HULL
