Safe top speed
Safe top speed
Hi guys,
I've been scouring the net and the forum but haven't really found an answer to my question - knowing me it's probably on the forum and i've missed it.
Anyway, I don't really believe the top speed supposedly being 80mph.
What would be a safe top speed for a grey and hydramatic? Given that mechanically it's bog stock with the exception of steel? timing gear. Tyres are 185/70 r13 (so a little smaller than standard bias plies).
I've had her bopping along at 60-65mph before, revs a bit but seemed to deal with it fine.
Was just wondering what everyone else thinks is safe enough that nothing will self destruct
Thanks,
Jimmy

Re: Safe top speed
I'd say 60 to 65mph. Anything above that and mine starts to moan and groan. With the tyres you have though, the speedo might be showing 65mph, but you'd be lucky if you were actually doing 55mph

Use this calculator to find our your speed differential when using non standard tyres -

Re: Safe top speed
Cals about right - she should do 60-65 mph all day up hill and down dale with just a driver in it. 5 mates and a trailer will slow things down a bit.
Depends a bit though on what state the old girl is in. Mine had been sitting for 10 years before I bought it... the timing gear didn't like it and gave up the ghost (despite having oil flow), as did the thrust bearings.

Re: Safe top speed
Hi all, made it comfortably sitting at 60-65mph (about 100kmh according to the GPS) ran like a charm:)

Re: Safe top speed
I stretched the legs on mine on the highway once and got it up to 85mph . It still had more in it but I wasn't game, to push it too far.
