John and I got the NX direct port kit working awesome for spooling the turbo at the staging lights. We may increase the jetting but for now here's what we used.

NX 8006-EFI - 6 cylinder direct port setup. Used smaller 18 jets on all 6 lines (equates to around a 75 shot). The kit comes with 26 size jets in it which is around 150 shot which I felt may be a bit too much. We set the nitrous to come on when transbrake is pressed and 90% throttle from 2400rpm to 4600rpm. 2 step is set at 4900rpm.

Time to hit the 2-step rev-limiter at 4900rpm went from 4.5 seconds to 1.7 seconds. This will work awesome on a normal tree, but may still be just a hair too slow for a pro tree depending on how fast the guy working the tree is. My torque converter is from Virtual Works and is terribly slow getting up on boost so the nitrous will really help.

Any feedback or questions, let me know.

Take care,
Chris.

Are you saying the VW converter is not what you expected or wanted? Is the stall too low or not correct for your turbo boost RPM (like you make boost at 4200 but a 3800 stall so a 400 rpm lag difference?). You make it sound like the VW converter is at fault, but I'm curious if you really mean the turbo is a big lag monster. Please clarify.

Correct, the turbo is not making enough power down low to pull through the converter. But the converter will stall to 8,000rpm once power comes on!!!

Do you have a video of you spooling, I would love to see it. I was told it is not good to two step on nitrous, you might get a nitrous backfire. Is this true, and if so how are you NOT making this happen. Thanks

We have the nitrous spray from 2,500rpm to 4,000rpm only when the transbrake button is pressed and the throttle is at 100%. Then the 2-step kicks in at around 4,300rpm.

No videos at the moment.
