Re: 90 mph in a 600 sedan

Greg Hahs · Post by **Greg Hahs** » Fri Nov 09, 2007 10:38 am

Just got back from a little drive to see what it does in all four gears.
1st up to 20
2nd up to 45
3rd up to almost 60
4th didn't try going any faster as I was in a 50 mph zone.
This car really runs great! I'll take Garmin with me next time to
double check.

Hi Greg,
You mention that you get to almost 60mph in 3rd gear ...... is it feeling like the power is dropping off at 60? You might be interested in seeing the rpms you are running. Since a tach is not stock equipment with a sedan, you might try hooking up your tune up equipment tach. The firewall has some plastic plugs which can be popped out and you can run a wire from the distributor to your tach.
When I hooked up a CD Ignition system to one of my cars, I used an Exacto knife to make a narrow slice in one of the plastic plugs in the firewall. I then ran the wires for the CDI through the plug and bolted the CDI inside the car against the firewall and under the glove box.
thanks for running the performance test on your car,
Dale

Hi all;
    I have to wade in on this one.
    First, I drive my Honda 600's at 65 to 70 all the time. Then too, I have and use oil coolers on my cars.
And, I have no problems. Yes, there have been people that chose to drive across parking blocks and done some off roading (I think) and knocked the hose off, causing all the oil to come out. But this has never happened to me, and I know of a number of others that have not had this problem. The best part is that you add more oil to the system, maintain constant running temp and you can attach oil pressure and temp gauges to monitor your engines operating temp.
    Second, the Honda 600 has two transmissions, a full synchro and a constant. Each has their own speedometer gear. The full synchro has 16 teeth, the constant has 15 teeth. Either will fit in either transmission. So, if you want your Honda 600 to look like it's going faster by the speedometer, then put the Constant gear (15 teeth) into the full synchro trans. Your speedometer will display faster speeds at a lower RPM, without going any faster.
    Third, 90 Mph in a stock Honda 600 is a dream or the hill is very steep and you have the clutch in. Even if you have 1.0 mm over pistons, reground the cam and put the larger carb on the car using the angle port head with dual exhaust, your Honda 600 will not pull 90 mph. The physical requirements are not available at the points. Both cylinders fire at the same time, this makes it physically impossible to make RPM high enough to move the full synchro transmission with stock wheels and rims to do more than 85 mph. The points only advance so far, which is when the RPM's reach around 7200, the points move past the rotation of the advancer assembly (lobe) causing the points not to open.
The engine stops running at that point not reaching 90 MPH. Do the math, and I don't mean the new math.
   Now, if we could get one of the more enlightened Honda 600 owners to make up some electronic ignition systems for us, the dream will be reality.
Bill

ok--NOW i have to go and try it again--THIS time with a GPS--(and a sundial) to see if she will do 90 plus---it's raining today, but should be clear tomorrow (sunday) ---i'll keep you updated--(unfortunately, it's been my experience that when someone uses logic, knowledge, and math---thanks, bill and miles---i'm left looking like an idiot, but it won't be the first time--)
more later--
