So what about the 5-second Top Alcohol engine? "Only" 5,000HP on Alky (instead of nitro) and they go the whole race (3-4 qualifying passes, then 4+ elimination runs). Or what about Super Stock? 1,000+ HP N/A V8's going an entire season without a rebuild (24-25 races at 8-12 passes each). You're still not seeing that the ENTIRE F1 engine made the same HP in race trim as ONE piston in a Top Fuel motor!

Look, I love F1 (a LOT), but it's apples-to-grapefruit here. Engines are soooo hard to "compare" to each other, and when you hit race-specific engines it gets even more so.

That's why a 400HP boosted 13B and a 400HP N/A LSx mean so little to one another. Throw that same turbo on the LS and tell me what happens. 600+ HP is what, with no loss in drivability.

You guys should be proud though. The LSx is pretty much the only sane swap for a 13B. Any other V8 is going to be way too heavy, and way too underpowered. Sure you still see SBC's and SBF's into FB's, but they become drag cars only. Even a stock 12A can run rings around those swaps on an autocross course! The LSx is still the world's most advanced V8 engine. It didn't hit the streets until 97 (Corvette, 98 for the f-bodies) and the basic 13B was available when, 84? So it took 15 years for the V8's to "catch up" on a HP/$ and HP/weight setup.
