So I did some further research. Looks like a big part of why 2 valve's make more low end torque vs 4 valve per cylinder DOHC heads is due to air velocity at slower engine speeds, which makes a lot of sense now.
2 valves per cyl allow for higher air velocities at low RPM, but ofc that comes with...
You can, but they would make the power very differently, no?
The engine with the longer stroke would make the power at a lower RPM with a higher peak torque figure, vs the shorter stroke making the power at a higher rpm and lower peak torque figure - assuming everything else is exactly the same...
How does stroke not effect torque? It makes perfect sense to me that it would, and I've never seen anything refuting it. There is simply more leverage on the crankshaft with a longer stroke.
Its really all to do with air flow. DOHC allows a more controlled air flow at a greater valve angle, along with less losses across the entire pushrod system.
As much as I love pushrods, they're sort of shit at higher rpms. Theres a lot of tricky engineering to make all the components stay...
Not as refined, but also better to drive in a lot of ways.
Atleast for the manuals, the Mustang has a better transmission (both Tremec and MT82), more breathable motor that likes to rev, and better gauge cluster setup.
Its arguable that the Torsen diff is also better in some ways, but worse...
This is a really great explanation of how it all relates.
Horsepower is, more or less, just an imaginary number that represents the amount of work (torque) is being done. The more torque at a higher speed, the more power (theoretically).
Its why old Honda's with low torque were able to make...
It might be pulling timing. Are you using 87 or 93? I'm pretty certain that peak power isn't made with 87, even though the car can run that octane without issues
Late C1 'vettes are probably one of the nicest classic sports cars, next to XK120's. Theres very little to dislike. Even the three speeds are totally serviceable. Thats one of the few cars of that vintage that I could say are totally something you could daily. That V8 is so butter smooth when...
You are very difficult to talk to, man.
I have given plenty of examples of first two model years cars having issues that were either later addressed, or could very well impact someones desire to own a car, as well as providing an example for our very own S650’s which show that, yes, early model...
Not to drag an old talking point on, but the exposed wheel well hole is a very small example of one of these first/second model year issues that are now resolved
I do sort of fear what these giant screens will be like in 10 or 15 years. I never sell cars I own, and drive them until theres nothing left to drive, so I do sort of worry on the longevity. My mind immediately goes to the fact that 10 year old Iphones are horrifiically slow and have many issues...
Its not an urban legend at all.
Just off the top of my head: Honda 1.5's were found to have bad oil dilution issues,
Toyota GR86's were found to have oil starvation due to factory fujibond/RTV being applied incorrectly.
Toyota Tundra's had metal deposits found in their motors, leading to...
