They are easier on parts, and they don't have belts like blowers, or turn into cutting torches like nitrous. A turbo LS with mild camshaft and stock rocker gear can make 1000hp, same with a gen III hemi. You can make a lot of power with a mild engine.
One year on drag week there was a guy who won the sealed hood award and it was a turbo corvette than ran low 8s or high 7s. I don't think you could do that with any other power adder.

Turbos produce their power in a gentler area of the piston p/v trace so they're going to be inherently better on the bottom end, and they're also more efficient than a supercharger in terms of parasitic loss. That's why there are so many stock block turbo LS's making 1200+ to the wheels. If they were N/A or nitrous motors they wouldn't live. You lose VE with a turbo because of the backpressure increase, but they don't require physical hp to turn like a blower. Prochargers make good power, but are fragile in comparison plus put additional load on the crank, and they are both easier on parts than nitrous.
If you are willing to embrace EFI and can fabricate a turbo kit, they're the best power adder out there, especially for drag and drive type events. Many of those cars have bolt on turbo kits available, so you don't even have to do any hard fabrication to do a turbo LS in a Mustang or Camaro.

Turbo is the way to go for the reasons mentioned above. My next build will be with twins as I keep gathering parts.

Just got back from last day of Sick Week. Tons of great cars, beautiful day. Seemed to be more 8sec cars than 10s, impressive. From what I saw in the pits, roughly 75% of the cars were turbo.
Is it cheaper power, more reliable, consistency, or other? . This might get interesting,din't think there's many Turbo guys here.

Is it cheaper power, more reliable, consistency, or other? Turbos are al of the above except "cheaper." Not that they are more expensive- its probably equal between a complete sorted Paxton type and a Roots type when all is said and done. Computer controlled port fuel injection has really made turbos much more feasible than back in the carburetion days.

The carb tech has come a long ways also but a good blow through carb that can support power is really expensive.
I keep going back and forth on turbo stuff, I have a 6.4 Gen III core on the stand I would love to turbo one day.

The down side is looks and sound though, the classic supercharger type of install always looks and sounds better. Definitely agree with this too. N/a, nitrous or blower cars sound better. A typical junkyard LS turbo setup does not sound aggressive at all. The only other drawback to turbos is they're more difficult to tune, you have more degrees of freedom with it and they're intertwined pretty heavily. Blowers are an easy transition for a nitrous or N/A guy as it's just making sure the fueling is correct and you then manage the power with timing. With a turbo car you have to juggle boost and timing at the same time, as pulling timing typically increases boost. However so many are running them now it's easy to get help, especially if you're running one of the more popular fuel injection setups.

The turbo stuff is great for good power & nice for a driver. My son & I have been hanging out at a local race shop that builds turbo kits & roll cages, they have a weekly hang out night to bench race & do quick projects that night for the ones hanging out. After checking out various customers projects, seeing the shops no prep 1/8 stuff they race & watching how easy it really is, my daily ‘67 C10 now has a turbo with a terminator X & my son’s FB RX7 now has a turbo with a blow thru Holley 650DP & MSD controlling timing. My truck, I got it together 1 week before RMRW 2.0 2022 & I did the whole week with 0 issues & now have about 25k miles on the set-up with only a O2 that I’ve had to replace. I am planning a turbo for it ‘67 Barracuda & it will be blow thru. The main thing I have seen is using quality parts & planning out the routing, it really makes for a nice driving set-up vs a high compression, big cam NA set-up

AKA, what does it weigh and how well does it handle It’s heavier than you would think, 2750# but it’s got a Viper T56, full interior, glass top & heavy old 16” JDM mesh wheels & I t’s the last year of that generation & they added 500# over the 6 year run with safety & stiffening reinforcements. It’s a riot to drive though, approx 600hp & 4.10 posi with a factory true 4 link.

The energy in an IC engine is roughly divided between shaft horsepower, loss through the cooling system, and loss through the exhaust system. Turbos recover some of the exhaust loss. It's all about overall efficiency.
