Finally got my WS6 #3392 on the dyno today. Below is the list of power mods rest of mods in sig. Before the D1X it put down 440hp, 399tq, after 625hp, 499tq. That is a gain of 185hp and 100tq with 8 to 9 pounds of boost. I am running Snow performance stage 2 Water/Methanol Kit. Also is has a very safe tune on it.
We changed out the Snow performance boost juice today for M1 methanol. Picked up another 20hp and 8tq. Nothing changed in the tune. Timing is at 19 degrees. New numbers are 645/507!
What fuel system are you running? Lonnies dual pump and stock lines? What injectors?
That cam works very well with the D1X... nice tabletop flat torque curve with the centri-blower.
If you don't have upgraded lines and you do those, you can def push to 14-16 psi... stock block might take that for a while and get close to the 800s. Looks like you're making about 20hp per PSI... so you should be able to extend that out to 14... so another 100 to 16... another 140whp. I don't know what the blower speed looks like... but you might even be able to get to 18-19 psi. Which would add about 200whp over where you are if you wanted to push it with a forged block down the line.
I am running Lonnies twin high output fuel pump kit with Hobbs switch, with stock lines and ID1050 injectors. Everything has worked together better than I thought. Below is the last dyno chart running the M1 methanol, and no other changes.
I like the build!! Great numbers! I have a F1A I am installing soon hoping i can turn it down enough to make the power you are making and later do a forged short block and turn it up.
