Hi, I have a TT GTO making 880 to the wheels on boost only,

Now I'm installing a Wet Nitrous system with a HSW plate I get some time in the past with a 150 shot,

At the dyno I get only 60whp more on NOS, I don't know why... I make a lb/hr test to the plate with the 150 jets and it seems to be OK

My question is, do I need to move to a nozzle set-up instead of a plate or what other things I need to check?

A plate is good for FI?

I would like to have your opinions, thanks...

 

What jets do you have in it?
What pressure is everything at?
Bottle should be in the ballpark of 900-1100
Let's start there

 

How are you doing the PPH test? Also, tell me about your setup and fuel system. How where the AFR's on the dyno?

 

I'm a fan of nozzle setups in general, but it may not be needed yet for you
