I've seen where some Japanese tuners have used the VQ in a r34 to lower the center point even lower then you could of with the rb26dett. I know this doesn't really pertain to the tq debate but just another note to add into the debate. I like my L28 in my Z and inline engines better just being alil more easier to work on instead dealing with two heads to deal with. It may be a taller engine but ease of working with it is a big deal with me. Just one reason why I would never buy a z350 or a sube or anyother v type engine. :)

Re: I-6 Vs. V-6
ARRRRRRGGGGGGGGGGGHHHhHHHHHHH!!!!!
Stop writing stupid things, just stop. You need to have the gas velocity in a certain range to manage to fill the cylinder properly, make the ports too big and your torque will suffer. Same applies to valves and cams, go too big and your performance will suffer badly. |
Re: I-6 Vs. V-6
The rod rotates on the pin on every engine, because if it wouldn't, the engine couldn't even turn over...

i dont know anything about engines :( |
Re: I-6 Vs. V-6
uhh.. the rod is what should tell you where the force is being placed inside the cylinder; on the compression stroke the angle faces one direction, on the decompression it's angled the opposite way. Simple as that. My inline 4 cyl doesn't have pistons that magically hop up and down, it does have a crank and some rods that rotate and exert force against the walls in the same way all piston engines do.
The only difference between inline and V designs would theoretically be a sort of gravitational droop for the V style since it's own weight is pushing itself into the lower cyl wall, but that's just a laymens guess as far as it really becoming a torque limiting factor. |

im sorry but you're both wrong, please understand i said cylinder walls not pistons. please notice that when a V engine rotates it is moving into the cylinder wall rather than straight up or down. and on the power stroke the piston is moving down at an angle thus putting more stress on the wall rather than moving down in a straight line https://www.homemadeturbo.com/jbliss/ex.jpg The cylinders are also not off-center. http://www.we-todd-did-racing.com/we...ZkMzF5NTQx.jpg you can see that on a i6 the static gravity pushes straight down towards the crank. On a v6, its pushes the piston up against the cylinderwall. |
