SRV8 Rises

[robert]

For those SRV8 owners, the SRV8 is to be re-introduced into the market. The ownership etc has been bought by Madgewick cars and will be based on Bognor.

The only reason i ask is because you say "on Bognor" and not in Bognor!
:P

I read up on the history of my SR and the original design was design to pass the German TUV and 650hp was a figure quoted for power capability, and looking at its traditional ladder frame and and steel panelling around footwells floors and transmission tunnels looks strong but a heavy car. Also the rear link radius arms? are angle towards the centre and not parallel, is this good?

Question, How come Racespec (Jay Leonard) claim to produce all parts for SR V8 (Sussex) as advertised in Snake torque? me confused.

Angled in radius arms is good. Parralel is completely useless unless the axle pivots along the top shock mounts and the diff

Hi (I'm back from the North)

Dave, so could you explain why angled radius rods are good and explain more basically what you said on the straight ones I am interested (and still learning) cheers.

Hi Graham.

First let me say that some manufacturers do not use radius rods at all on Jag based cars.This does not mean that their cars are inferior (GD run 560 BHP through their race car without radius rods...and win)

It's all to do with geometry. The Jag rear suspension pivots along the fulcrum pins that are mounted in-line (front to back)at the side of the diff,so if you can imagine as the wheel bobs up and down when you drive over bumps in the road the wishbone arcs from that point, so if the movement was exaggerated from the side of the car the wheel would appear to move up and down perfectly vertically and if viewed from the rear it would flap like a wing.so with the pivot point being a line running front to back and at about 6" from the centre of the car anything used to strengthen this set up would also have to pivot along the same pivot line,which means that the radius rod must be angled from the hub into this line otherwise the whole system will bind its self up, and as the wishbones on the Jag axle are bearing mounted so must the radius rod and a rubber bush would serve no perpose other than to impede the action of the natural movement of the suspension.
A radius rod that runs from its fixing point on the wishbone straight forward will run in a completely different arc,If it is fitted to the chassis with a rose joint or similar type bearing and bolted solid to the wishbone the suspension will not move,and as i said before to use rubber mounts will serve no perpose except to destroy the mounts in record time unless it's as soft as a bath sponge.
An easy way to test this if your car has radius rods is to jack up the car remove the wheel and shock absorbers then move the suspension up and down, the suspension will freely move through the full range with correctly angled radius rods.But with straight ones it will tighten up after minimal movement,if the straight rods have a rubber bush fitted watch how the rubber goes from being stretched at full suspension droop to being compressed when horizontal back to being stretched again when the hub is pushed right up into the wheel arch .
It's a similar problem to bump steer...to reduce this some kit manufacturers used to make the front suspension very stiff with the thinking -the less it moves the less the problem...but this still doesn't make it right though.

If all this doesn't make sense...cos i'm having trouble following it myself ring me 07785 702005

P.S. the owners of these cars know who they are... so if i'm wrong about some or all of this please explain it to me and restore my faith in what is otherwise a very nice car with some stunning examples out there.(this is why i have mentioned no names)

Cheers Dave,

I thought I read somewhere that the original designers of the SR chassis originally spent time at Dax and Ram, is this so? it would add up.

Thanks for your help again.
