Vibration at >140mph

[chrisdadd]

Don't ask where. I did have a big smile on my face when I took the TuscanRR to 140mph...but g*d did it vibrate. The noise I love. The vibration I can do without. So...do you think it's the wheel balancing or is this beast supposed to do this?

By way of driving contrast I get none of this excitement/stress when doing the same speed in a GhiaX 2.5 Mondeo.

I can't see how the Tuscan would reach it's top speed without shaking joints apart :-)

Keep your foot in, it'll soon disapear, not as quickly as the horizon mind you!!

Interested in any answers as I get the same in my lowly Chim, from 125 / 130 I would say. Also seems worse some days than others, no idea why.

Could be a bent wheel, the TVR spiders arnt the strongest. Get then checked out. I used to take my Tuscan RR to 170+ on many occasions, with no problems at all. The wheel may have a flat spot, or, something as simple as wheel balancing.

Oh, be warned, take some time to learn the Red Rose. It took me 3-4 months to understand the car. They stick like glue, but if they let go in a big fashion, you will not catch it, and you dont want this to happen at 140 +. The problem is becuase they stick more, the let go at higher speeds (in refrence to your other thread)

Just take some time to learn the car is all I would say...

I agree with MrFreefall, wheel out of balance or more probably not round anymore.

Chris,

Worth a trip to Silverstone TVR, I learn't so much about wheel balance and runout I could win any pub argument , they use trick balancing gear that has zero tolerence when spinning the wheel up. Plus if that doesn't cure it they apparently have the use of a closed road to diagnose high speed problems such as yours (and no it's not the circuit!)

Just to add to the previous posts, the Red Rose will happily exceed 140 without vibration, so I would suggest getting your car checked out, also the Spider wheels were changed in design to strengthen them, so while it is tru to say the early spiders were weak, I am not sure it is true of the later cars

Suspension geometry slightly out, or maybe some part of splitter or front under tray missing?

[Graham66]

Red Rose doesn't have a front splitter or under tray, the S has a splitter, not sure about the under tray though

Suspension geometry or bent wheels sounds most likely
