A couple local guys run carbs with nitrous and e85 they did drag week a few years ago never had any issues and were running low 8's and 9's it's more of your tuning capabilities with a carb both are good and bad.
E85 is awesome. And it's good insurance so long as you're not using winter blend.
I'd be interested to see if their systems were direct port or using a plate. I trust TPI with a carb and using kits that are +500hp. To me, plates can be sketchy above that level. That's just my experience.
There are plenty of guys going 8s with nitrous and a carb. Tons. But I've been doing this long enough to know that big horsepower kills parts. EFI allows the mill to live longer because I'M telling it what I want it to do. I can manipulate almost every function with the touch of a button and data log everything. I can also program it to shutdown in the event of a lean condition or a knock to save itself. Traction and wheelie control. The benefits far outweigh the negatives.
Technology is our friend in this case. It just costs more and there's a learning curve.
