Where to go next? Low 11's high 10's??

No, no idea. Yup. You got me. Sorry man, Just not impressed with any car running nitrous. Never have been, never will be. Boring no matter how built the engine or complex the nitrous setup is. Do it on motor. More impressive. :icon_fU:
It's no different than any other power adder.. forcing more air&fuel into the same space...
Boring is your personal opinion and I'm not trying to change that or what Impresses you...
Maybe educate you that it's nowhere in the naborhood of "slap a kit" on it...
Mindsets like that generally end up as a catastrophic YouTube video...
