V6 versus inline 6.

[CRISTIAN]

Say you have two 6 cylinder engines, both have the same displacement, technology (# of valves and things like that), and are built of the same metal.
which one would produce more torque,? more hp? which one would rev hitgher? Does the shape even matter?

[jetjaguar]

The straight 6 would produce more torque because of the way the pistons are connected to the crank shaft.

Straight six is also better if you want to go for big dyno numbers with a turbo due to all the cylinders dumping into one header making it easier to spin a huge turbo (like the supras and skylines.)

Short answer:
all things being equal (bore x stroke, flow into engine, etc...) an inline 6 would make more torque, and probably more hp.

long answer
If 1 has a longer stroke it might make more torque. One of my teachers are UTI said that Inline-6's are great for torque because of their long and heavy cranks shaft, they have a lot of inertia, compared to even a v8 or v6. An Inline-6 for the most part is a better engine, it's supposedly perfectl balanced, is great for torque, and can still rev quite high given it has a short enough stroke. A v6 is only better because it's not as long, but it's also wider. Otherwise a v6 is pretty much a bad design, they are unbalanced, to run smooth they have to have a weaker designed crank (split pin cranks) but companies have made them plenty strong anymore.

If u want the greatest it torque it seams u want a long stroke inline 6. My dads dump truck has a 854ci Turbo charged Inline-6 diesel. it makes plenty of torque to accelerate a 23 ton truck to 30 quicker than my beater (80hp nissan sentra). If you look at many semi trucks, dump trucks, and similar they all will most likely have an inline 6.

so this may sound dumb but then whats up the slanted 6, i know they were pretty powerful too even in trucks

Slant-6 is just an inline-6 with the motor pivoted twards 1 side of the car, for better hood clearance. I believe bmw's have the engines 30degree's to the passenger side rather than Perpendicular to the ground.

The slanted six is just a straight six slanted over 30 degrees. For a little history i found this site, http://www.allpar.com/slant6.html

no for real tho it does

[RotaryWeapon]

I like the sound of the Inline 6 better also. Like in the skyline or supra.

Slant Six ..... Nicknamed the Leaning Tower of Power. not because they had some snap but because you cant kill them. rocks in crankcase ...... chews'em up and spits them out. no oil pressure ahh its good for another 10000 miles

lol my brother drove from Campbell River B.C. to Parskville B.C. ( about 100 miles or so ) at 90 - 115 mph average with no oil pressure in his 1975 Duster that had a 265ci Slant-Six and it didnt die lol didnt even over-heat. lol he needed a new oil pump but we cant sweat the small stuff

yea my mom had a 1970 duster she rebuilt with my dad ( yep im just liker her lol) and that thing was sick...she sold it years back tho

[Traction Issuez]

thats the only motor i haven't been able to kill. i'v killed 4s 6s 8s but never my strait 6. that poor old 64 acadian took a beating and kept asking for more. i miss her.
