I like the nelson racing setups, 1600hp, twin turbo, bigblock, 2 injectors per cyl, one for pump, one for race gas, car runs on pump untill boost gets to a certain psi then the race fuel kicks in and stats making way to much power. Expensive as hell but you can have a 1000+ hp thats streetable, gets decent mpg untill you get on the boost. Check out nelson racing engines on you tube, if I ever hit the lotto thats where im going lol.

Whos shop do you work at? I also race in NMRA in the SS/O class. So im pretty well rounded in DFI as I use to be sponsored by FAST. While there is nothing wrong with DFI, its just a waste of money for me in a street truck that is will never see 1000+hp. So a nice CSU carb and a 88mm turbo will do just fine.
I have switched gears from racing and looking for more of a fun challenge then whos got what and how fast does it go. Because none of the classes anymore are what they use to be.

Much easier to get right with fuel injection. But to each their own. I would much rather a couple keys on the keyboard than pulling a carb apart and messing with jets. But that is just my personal preference.

DFI must not be what I thought it was. I thought DFI is a brand that manufactures aftermarket EFI systems.
EFI does not have to be expensive. I have an '88 Firebird and I have to tell you, the late 80s, early 90s GM efi systems are very tunable with the right hardware, which is not expensive. It would not be too difficult to adapt one of those to any engine. I can plug my laptop into my car and see exactly what is going on with everything in real time and record it for play back at a later time. While it's not a powerful vehicle by any means, it will burn rubber, and consistently gets 28.5mpg on the highway. You can get most of the parts you need for this from a salvage yard if you really wanted to.
And you really want to take the diy approach, there is megasquirt which, again, does not have to be expensive and people have done amazing stuff with it. I know of a turbo efi Y running megasquirt in Finland.
It does have a lot to do with cost, too. There are more people willing to spend $3-400 on a carb than those willing to spend $2000+ for injection. For some, injection simply isn't in the budget. I really think that if carbs are the absolute best, then the oems would still use them. Even powersports vehicles are moving to injection.
