OK. Now, knowing that I said that when I would notice that I was doing 4K RPM I would back off. I usually run a little past 3500 RPM in real life. I also run watching my oil temp, whick to me, is the more important reading. I back off if I hit 220 degrees. Thanks for all the math. When travelling long distance i do believe I average around 68 MPH. I guess tha Murray wanted to get home. ----- Original Message ----- From: sammie smith To: tcb@xxxxxxxxxxxxx Sent: Wednesday, April 23, 2008 10:10 AM Subject: [tcb] Re: Home OK, you big math heads I got the 76.4 using 23.5" tire diameter. You must have used his 24". But whatever, it's too darn fast for a bus, even if he does have a sway bar. evilscientistboo@xxxxxxxxxxxxx wrote: Assuming a 3.667 final drive at 4000 RPM I get 78 mph (77.9) The dog's motion is relative to the bus however if you measure relative to the road it is moving at 78 mph. -----Original Message----- From: Denis Dodson Sent: Wednesday, April 23, 2008 8:57 AM To: tcb@xxxxxxxxxxxxx Subject: [tcb] Re: Home OK, you big math heads 23 1/2" to 24" ----- Original Message ----- From: sammie smith To: tcb@xxxxxxxxxxxxx Sent: Wednesday, April 23, 2008 8:51 AM Subject: [tcb] Re: Home OK, you big math heads Denis: We can calculate if you will get a ruler and go measure the diameter of YOUR rear tire. Tire diameters vary by brand even for the same size So measure your tire.
