Piston Velocity
Can anyone tell me off the top of their heads what the stroke of the VG / VE motor is? The numbers should be very close since we are talking 181 vs. 183 cu. in.
I knowledgeable coworker was telling me that running a motor for a long duration at over 30 m/s accelerates engine wear (pistons / cylinder walls). This may or may not be entirely true, but for fun I wanted to calculate the piston velocity which I could, in turn, use to find out the speed / rpm at which my car / motor starts moving at faster than 30 m/s.
Just something I thought I'd do for fun...

Almost forgot about posting this...It is actually 30 ft/s and not m/s.
The results I found are that our motors are moving at 29.95 ft/s at 3300rpm.
I am not validating my colleague's claims, but based on his logic your motor sustain less wear if you cruise at 3300rpm or less.

Yeah, lower piston speeds wear less. but driving slow sucks more.
drive fast, live happy.
Now for some fun.. Here's a VQ35 in a 300ZX turning 8000rpm.
How's that for some piston speed?

Also notice the Lexan windshield starting to bow in at around 100mph. scurry.

Looks like 3300rpm in my car with the VLSD 5-speed tranny is at 83 or 84 mph...That works out perfectly because that is a good cruising speed on most Houston roadways.
