420 SEAC restoration begins

[Transmitter Man]

Hi Jason,

I'm afraid I cannot answer your question other than the fact the Tuscan racers were noticeably lighter than even the SEAC and probably had similar fully rose jointed suspension.

I'm sure other more knowledgeable people here can answer your question.

Phil How different is your chassis to a tuscan racer ?

I think the chassis on the racing tuscan was created they used a modified design for the griff chassis and then the chimp, it was lenghened for the cerb too.

Also the man that designed the wedge chassis worked on the tuscan racer, he was also a ex lotus man and followed there design ideas at the time hence the way the back end was designed.

The racer chassis is fully rose jointed top and bottom wish bones and the joints to the hubs.
I think this is correct...
Hope this helps

Very. The only common point is the use of steel.

At least it was steel and not what the factory had on the shelf at that time.

This comment is due to what I found on my car after we took off the body.

Latest update, taking a little longer and costing more than first thought (where have I heard that before);





I wonder if any of you can guess what I'm doing to the rear end?

Don't let the cat out of the bag Henry.

Would they be Tuscan rear hubs with outboard discs to be fitted?

[pwd95]

Won't handle very well without wheels mind Phil.

[Transmitter Man]

Can't afford wheels.

Designing it to run on rails:



Yes, outboard discs using Jag hubs.

The drive shaft on the Jag is to long so we will have adjust the length.

Can’t use your old shafts as they have bigger uj’s and will not fit inside the hub.

Lower arms will not fit inside the tyre or rim. Also the fixing on the Jag hub is not the same.

We will end up with too many mods to the lower arms…so it will be better to make new arms.

Why?

[adam quantrill]

Because it's there??

Don't like the sound of smaller UJ's - the existing ones are on the limit. Then the outboard discs add to the unsprung weight. Then there's the brake pipes. Hmm, sounds like a job and a half!

Good luck with it anyway.

[Henry Harris]

Phil, no cat and no bag, but what are you doing about fuel tanks? Will there be any?

[rev-erend]

With those tyres .. Strange / Dana axle with leaf springs.

Up front - SBC with NO2.

Hi Phil

That rear tyer looks sick under the back of your car, hope its going to look as good up front too.

If your going to use tuscan hubs in the back there should be a prob with the size of the UJs, are you installing top with bones and having a telescopic drive shafts?
As far as the existing drive shafts on the SEAC if they are the larger diameter as they are on mine they will handel more than enought power, just look at SH purple monster and the power running through the back end with little change to bearing or drive shafts i think.

I gess the cost of all this work is adding up then you have the gali to get done, you could paint the chassis to cut the cost of having the suspention geometry sorted, looking good Phil keep us updated

Adam,

I'm aware of the unsprung weight issue/argument but would just like to follow the route of all the later TVR's. I also don't like looking at fresh air through the rear wheels

Hubs are Jaguar not TVR.

I do not intend going mad in the power department and will only be using the car on the street so do not forsee any drive shaft issues.

New ali front hubs being machined so will end up with Jag pcd all round.

Stay tuned.

Henry,

New design fuel tanks will allow room for the 285's and at the same time will increase capacity.

A win win situation.

Alan,

Strange axles are very nice but really not needed considering the weight of a Jag saloon with V12 power, I'm sure the IRS will be fine- just need a proper job on the drive shafts.

Several guys at the Pod with Jag IRS running 9's with 800+ horses and no problems.

Cannot wait to complete front & rear suspension so we can strip back down and get the chassis galvanising out of the way ready for the rebuild.

Hi Phil

Dont suppose you are getting rid of your old driveshafts, if so would you be interested in selling them to me? Mine is the wedge that i dropped a 5 litre into.
cheers, John

[Transmitter Man]

Hi John,

I have decided to sell all left over stuff after the rebuild rather than as I go basis, that is other than the SH tie bars which I promised to Shaun if he still wants them.

Stay tuned.
