I have cars of both types (well, not a 500hp stroker, but a 440 tnt 4-speed anyway) and they're both fun! Instantaneous torque is great, but so is the rush of an engine that just pulls harder and harder as you wind it out. I'm not sure which would be less dangerous in a 2 ton cruiser, though I'd think the torque monster would be safer. With a torque monster you run the risk of loosing traction and control on launch or shifts. But with a turbo, you can loose traction once you're already moving when you hit full boost. Also a turbo encourages you to go faster because you will always want to wind it out to get that adrenaline hit :D

I've ridden in my friend's supercharged 09 Mustang Cobra and I'd say it has the best of both worlds. A turbo setup can ultimately make more boost/top end, but if you're limited by knock or other engine factors, to a modest boost pressure, I'd say a super charger would be the way to go.

I see your point as a supercharger makes the engine act and feel like a larger displacement engine and still no lag. The 09 Mustang Cobra you mentioned is 3920 LBS similar to our C bodies weight. To move weight from a dead stop torque is king not hp I would think and the Supercharger has lots of grunt down in the lower rpms like a stroker. Turbos benefit from a manual tranny as you can down shift to keep the turbo spooled for the next straightaway. Aggressive launching my Omni was /is difficult as you can easily blow right through your traction limitations. I tried to get around this by taking the control of the wastegate away from my computer and have 2 adjustable boost settings ,one part throttle and a second full throttle and that gave me a fighting chance.

Yes, I've had a 525hp 440" and it was fun, but came with 4.56's...a stroker doesn't need the gear
Turbos, like diesels, like load, sitting against a converter and against less gear

That's a low gear for sure. Was it a drag only car? My stroker will have a 3.23 rear and a custom 11 inch converter made to the same specs and the same shop that made MEV's for his New Yorker.

yes, that was a setup in my Coronet. Very snappy! It had 30x10 slicks on it and I drove it around a little bit, with those tall tires you could run 55mph on a 2 lane but with the 3.5" header mufflers it was not a quiet ride!

Well we're way off topic now... But no because I never had the right converter in the car

It seems most of the time those sorts of tests are running really good gas unless they make a point of telling you they are on pump 93.
In the real world e85 isn't something you can count on for a street car without a flex fuel efi, there's no consistency for it at the pump from e50-85. At the track is different.
I've only used water so far but might eventually tip in some methanol.

All those guys on Youtube are scarce on specs usually and least of all octane rating to do what the engines do. They should at least say that. Hell they may blow it up and we wouldn't know it to get their numbers. Or lie.
