Ha Ha Ha for Bolivar Speedway it would have to be turned the other way. Just switching lanes while taking a picture. I had the winter car blues questioning why I had them. It was a beautiful day went for a spirited drive...oh yeah thats why, all good.
Is it Auto or manual? Just musing - speed is 110mph (being generous considering the precision of the Ferrari speedometers), 1000 revs before redline - what's the indicated speed at redline, can you go back out and give a report
The speedometer showed about 5 mph less than the gps on the phone . I was as curious about the accuracy of the tach. Rounding down to 110 and rounding tach up to 6000 rpm would give us a 128.33 at 7000. The car would easily pull redline in 5th and I believe beyond. Did give the knock offs a good wack before I left, but I should have checked the pressure in the 12+ year old P6000's. Greg I don't know if you ever go to Wheatland, but if you do let me know, bet they would give us good parking. Give me an excuse to sort on my rather dim instrument lighting.
For the enlightenment of the rest of the members: the Lucas Oil track facility is larger than the town of Wheatland, MO. in which it is located. It is a dirt circle track complete with Grand Stand seating. I'd bet we could do a couple of laps any night as the pace cars, or maybe as our own class! Greg
Was your odometer reset at one point, or are my eyes deceiving me into seeing that your car only has 70+ miles, or?
Good to see you out having fun. I miss our open speed limit. What gear were you in at the time of this shot? My auto changes from 2nd - 3rd at 100MPH under full acceleration. Cheers, Al
Your eyes were not deceiving it is showing less than 100 miles. When I rebuilt the car and engine I replaced the KPM with a new o mile MPH speedo. We put about 40 miles and the cable gave up the ghost, so drove it maybe a few 100 miles with no speedo. This was my first drive with it operating again.
Wow, I had no idea those cars were geared that short. I thought they were 140+ mph cars, at least on paper. So how slow can you go in 5th and still have good tractability?
The auto's are no where near that short. I've had mine maxed out to 160MPH on the speedo (252kph on GPS) & it hadn't hit redline.
The autos have a very tall diff - it's one of the things you need to change to convert to manual. I think it's in the low 3:1 somewhere, and the manual is closer to 5:1 - I'm sure someone can chime in here with the actual numbers.
Interesting. Thanks for the responses. I'm still really surprised at the revs vs. MPH in that pic. I was guessing that the OP was in 4th based on the revs. I would have expected a higher (actual) top speed from a 5 speed car.
I always thought the 5-speed achieved its top speed at redline ? 128mph at 7000 seems off. Do you have original tires ? The 400 has a 6500 redline and when cutting that to 3250 I have 120kmh/75mph - so proclaimed top speed of 240kmh/150mph seems correct. 365GT4 2+2 has same rear ratio as the 400GT 5-speed - 4.3:1 with 10/43 stamped on diff and 400Auto has 3.25:1 - 12/39
Just perusing the manual - 152mph for the manual, 149mph for the auto (also has 15" wheels mentioned in the manual, so might be some slight variation). Diff ratio 4.3 in the manual, 3.25 in the auto Edit: I see Arvid beat me to it! I should type faster.
Manual cars have a 4.3:1 ratio. From contemporary road tests fifth gear gives 22.8mph/1000rpm which would mean 148mph at 6,500rpm. Maybe the tachometer in this car is reading too high ? Sent from my iPhone using Tapatalk
Astute observation. I trust my tach as much as I trusted a previous girlfriend. I have a bouncy tach needle at idle. When the engine is off the tach is registering 1000 rpm. I am not saying it is off that much I believe it anywhere from 10 to 12 %. Hopefully the sort will only reveal improper cable installation. (cable not seated in distributor or tach). When running on the 55 mph highways I will stay in 4th. 75 mph the engine is not lugging and feels comfortable in 5th. I am running 215 70 15's I believe are original sized tires. So nothing small in diameter which would show higher RPM than normal.
