Engine Masters Challenge 2013

I don't know how many of you guys follow it, but its pretty impressive what they can do with these engines.

This year, they were 400+ ci engines, scored from 3000-7000 rpm's. New for this year is allowing 4V heads. Ford Mod
 Motors were there and man did they represent. All the engines made lots of power; a few Chrysler motors, a couple Buicks, an Olds, an AMC, and of course Chevies and Fords.

In the end, it was down to the top 5; two LS motors and 3 Mod Motors with Jon Kaase coming out with the win. One modular was making 775 HP N/A and 600+ ft/lbs. ! This should be a big deal to the Mod Motor world, seeing how 90% of the combinations out there are supercharged or turbocharged.

There is no substitute for N/A power. Period. Glad to see more people are starting to embrace this.

I believe most of us are near (or near enough) to sea level for N/A to be ample. A kompressor makes more sense for anyone living at altitude.

That was something else which helped Granatelli / Studebaker while at Bonneville; they had an impeller grabbing at more of the thin air.

I am an all motor guy all the way, I will always prefer a built motor over turbos and blowers. With that being said, I couldn't disagree with you more.

Forced induction has allowed many engines to produce for more power than ever could have been possible before with near stock driveability. Not too easy to accomplish N/A.

Perfect example: 2013 Shelby GT500. 662 HP stock, with a warranty, no lumpy idle, no harshness or other quirks that come with a built N/A motor.

Not my point. A 700HP N/A motor is far superior to a 700HP whatever-charged motor.

Think of it like boobies: Real > Fake.

I'm with stalker all the way.   I love a N/A gas motor through and through but folks in places like Mile High in Denver would much rather have a Turbo/Supercharger setup.   All depends on the application.

Super/turbo chargers will still be affected by the altitude. They won't generate as much boost, since the air can be compressed more.

I'm with ya. N/A is my thing, its more appealing to me and proves more to me than something with FI.

FI costs a bit more up front and has more tuning involved, but bottom line is that FI will make more power, easier, and more reliably.

You're correct Sim, though kompressors give 30 to 50+ percent more power (varying amounts of HP & TQ) over their naturally aspirated siblings closer to sea level, and they lose ≈15% of both at altitude. It's true, they aren't making the power they could be, though I'll take the ≈22% power increase (% gained, altitude corrected) over what I'd have at altitude with an N/A engine.

Air density side note-
Coors Field (Colorado Rockies) is using a humidor [storing baseballs at a controlled 70°F, 50% humidity] because it was noted the air resistance there is circa 9% less (first, third, and fifth links are good), which is why so many home runs were being hit prior to the humidor's first use in 2002.

I totally agree with Sim.........on the boobies.  I stopped reading after that.

I like both!  Generally speaking though I lean towards NA motors.  As long as it puts a smile on my face I'm happy though.
