New car

[greenisbest]

Just bought 1997 Cerbera from julesby. Thanks for your help Jules. Based in Southampton.

Bet you can't guess what colour it is-(hint not blue)

Initial testing indicates that a lot of smiling will be done

One thing I do need help with-does anyone know how to drive these cars at 30mph? Please help or loss of licence is possible. Does driving in reverse help?

Congratulations on your purchase. By all accounts you've got a 'good un'. As for driving at 30mph, if the throttle pots are OK, no movement in the ball joints on the throttle linkage then it shouldn't be a problem.
1st/2nd gear - apply necessary amount of throttle with right foot etc. Driving at over 30 in built up areas is just asking for trouble. Now if you're talking about 60mph on open A roads with good visibility I'm afraid I cannot help. Cerb's labour in 5th at that speed and in any other gear you're tempted to toe it!

Darren.

Congratulations

What problems are you having with low speed driving... drivetrain shunt at REALLY low speeds, or just finding the urge to press the loud pedal? Personally, my car makes a distinctive exhaust note at spot on 2000RPM, which is really useful, as...

2000RPM in 3rd = 30mph
2000RPM in 4th = 40mph

Really good for matching speed limits (just ignore my previous posts about getting a speeding ticket ), and there's not too much torque/engine labouring at those revs

Oh, and blue cars drive better at any speed.

Drive carefully...

Adrian, get yourself a radar detector like I had, at least then you know when to pay more attention and when not!!!!!

James,

Do you know the speed per 1000 revs in top.I'm speedo less at the moment and figured 90 = 4k revs ish?

[mart 1963]

Doing 90 today along the A55 90=3K REVS.

I think I get (a bit under) 50mph @ 2000 RPM in top. So that'd be about 3500-3600RPM at 90. Not that you'd be travelling at that speed.

90 @ 4k can't be quite right, or you'd be at 8000RPM at 180... I'll check it precisely tomorrow for you. What an excuse for a quick blast.

I definitely don't get to 90 @ 3k. That'd gear the car to 6700 @ 200mph, which would be nice!

[_DJ_]

thinking about it, I think I guessed 4k was around the 100 mark so stayed below it (on the private test track etc etc).

[mart 1963]

It must have been 90KPH

Or 80mph?

Sounds about right. I'll let you know for sure once I've been on the very same private test track tomorrow.

[mart 1963]

Tried again today on test track 90mph 3k revs. Red cerbs must yust be faster.

[j_s_g]

How curious, I tried today - 79mph @ 3k RPM. "TADT, sir"...

Same size wheels/tyres? If not, could just be the 10% speedo differences...

Probably not, as I'm running 40mm profile tyres on the 18" spiders. But that wouldn't affect the reading unless it's actually being taken from the front wheels (35mm profile). Surely there'll just be a sensor on the diff/rear axle that it's multiplying to get the MPH, though?

[GCerbera]

Congrats Adrian but sorry you had to let it go Julesby.

It's taken from the rear wheels. I would imagine your speedo will read differently from a car running the standard (I think) 16", 45mm though.

julesby - make up your mind. one minute selling it, next minute not selling, then sold...

good to see its gone to another local owner though.

GPS 90mph at 3500rpm on the way up to derby this morning.
