Re: WOW... 90 mph in a Honda 600

Post by zinc2u »

Hi Paige,
     The next time you are doing 70 mph in the Z600,  would you take a look at your tach and let me know what it is reading?   I am expecting it to be at least 6,000 rpm.
      I am suspecting you and Greg do not have stock engines.  Greg mentions going 75 mph in a Mini and having a 600 sedan accelerate away from his car by 10 to 15 mph.  And then you mention going up to 95 mph .... how long did it take to get to that speed?
     The stock Honda 600 takes about 22 seconds to get up to 60 mph and you can feel the acceleration as you go through the gears until you shift into 4th gear.  Once in 4th gear (which is an overdrive ratio),  the car has slow acceleration.   If these cars are stock and they are going 90 mph,  I would expect them to take at least a minute to get from 60 to 90 in 4th gear.   The Honda performance documentation is showing the torque curve (and therefore the horsepower) has peaked by 60-70  mph.  According to Honda,  a stock 600 should not be able to attain a speed of 90 mph.
      My personal experience has been the cars have lots of zip until they get into 4th gear and I never intentionally run the cars past 6,000 rpm because it is a red line condition.  If I break it,  I get stuck fixing it and the damage is seldom minor.
      But I am curious how many people are getting speeds in excess of 70 mph on a stock engine.
thanks,
Dale

sure--no problem--i'll remember to look at the tach--i think it took at least 45 seconds to go from 75 to 95--could have been a minute--wouldn't have surprised me--my car is very clean and is showing 8,000 or so miles--have no idea if that's original or not--i'm pretty sure the engine is stock--also wouldn't be surprised to learn that the speedo isn't 100% accurate, but i WAS flying by traffic--didn't have a chance to see the expressions on people's faces as i whizzed by --- i was watching for cops and listening intently for the motor to explode (actually sounded pretty happy) i'll keep you posted

I grew up from the age of 4 yrs. with a Honda N600 for a brother. My
Dad got his new from the Honda dealership that he ran the parts
department for. He drove the wheels off of his and I got to
participate in the fun from the back seat. His was slightly bling'd
with a custom instrument panel, the tach of which showed an 8500RPM
redline for this car. At 90 MPH (downhill with a tailwind) the tach
would be in the neighborhood of 8000 or so. Being a long time ago I
can only offer an approximate on the tach. I don't consider myself a
true 2cylinderhonda citizen as yet as I still have yet to get a
little Honda of my own. I called my father for this information and
am quite certain of its veracity. The OHC motorcycle nature of this
small wonder of an engine should and probably did support revs well
into the redline range in short bursts. I remember slightly modded
versions of these cars competing alongside the mini-coopers and
Longman special minis on the Carribean Racing Circuits in Guyana,
Trinidad, et al. Yes damage was done to this car but it was more
along the line of body, suspension... I am certain that the engine
never sustained any damage (only wear and abuse) it never required
parts other than external stuff like alternators and such. That's my
two-cents worth.

Driving these cars at sustained high speeds (in exess of 75) will do detrimental harm to them. This is not an opinion, but a fact I have learned from working on the results of such behavior. 72 MPH puts them into the redline. Crankshafts are not cheap and are few and far between.

Just this morning.
My speedo:
70mph = 5800+ rpm. flatish interstate.
65mph = 5500 rpm (this is where I live.)
1972 AZ 600 W/new rings and .25 mm overbore.
This is on your basic khumo 10" tires and wheels.
And yes it takes forever to get to 70mph unless it is downhill. On
downhill I have to hold back to keep out of Red land.
I am toying with an electronic ignition, will let everyone know as
soon as I save up some $ and rig something up, have a really strong
lead on a source of parts to canabalize.

Did you check out my photos of an optical ignition? In the photos
section - crane optical pick up and MSD box. Wound real high real
clean. No points to bounce . . .
