0-60

Post by paulsv8manta »

Here's a question for you mathematicians.

The Rover sd1 3.5 weighs 1915 kg giving a 0 - 60 in 7.1 seconds.

If said engine is transplanted into a car weighing 1065 kg what would the 0 - 60 be?

Haha, a lot less!

I'm not sure you can calculate it with any degree of accuracy can you?

That weight is Gross laden, curb weight is approximately 1500 kg then add your weight.

Too many variables to calculate accurately but at a guess just over 5 seconds.

There's no doubt it can be calculated...but with so many variables, you'd need a lot more info, especially about traction available etc !

F=ma so assuming (big assumption) that force is constant

a= (mRover * aRover) / (mNewCar)

aRover=3.77 m/s^2 according to http://www.procato.com/convert/

1915* 3.77 / 1065 = 6.77 m/s^2

6.77m/s^2 = 0-60 in 3.96 seconds :D

Both my V8 Minors weigh around 1100kg. Rover 3.9 engined one with hurricane cam and edelbrock carb and inlet through a jag IRS and BW 65 box does a 14.7 quarter at 96 mph - around 200 flywheel hp. Probably equates to 0-60 in around 6 seconds. My other Minor with an LS1 5.7 litre with around 350 fwhp does the quarter in 12.2 @116 mph. GM 4l60e box and Ford 9 inch rear.
Both cars have a power sapping rear end - more so than an SD1 I'd say.

My 418hp SD1 run 7 years old road tyres witch are like stones. 2.7s/60ft and 112mph 13.9s 1/4 mile.
6.4s to 0-82.5mph. It will weight with driver and full tank 1700kg.
So 0-60mph would be under 5s. G-tech say 4.6s..

My 2800kg Range Rover sport 4.2SC make 0-71.2mph just in 6.4s. 1/4mile 15.3s and 92.5mph. 60ft 2.3s every time.

It is near as fast as Suprcharged corvette with semi slicks 0-60mph. Couple of tenth second slower.

My GT40 was1140kg at SVA and I added soundproofing and bits since then so 1200?

Shows a trip I did to Santa Pod and my timing sheet
Lots of wheelspin on street tyres, no special preparation drove it there and back, even had tools and my lunch /water on board!

Dino says 250 ish HP out of the 3.9, at the flywheel, and transaxle soaked up about60 of those!

The figure you've given for the SD1 is the gross vehicle weight. Showroom weight is quoted as 1440 max. That 7.1 O-60 won't be achieved with the car fully loaded.
