We have now started development work on a moulded carbon fibre Monocoque version of the TSC GT40.

The design work is being done by an F1 chassis design engineer who has worked for both Lotus and Lola.

Monos and cars will be available hopefully before the end of the year.

Pricing will follow our usual pricing format.

I will post more details as and when available.

Thanks

Andy

Its the ultimate chassis. Light, strong, and stiff.

We are going to build the ultimate GT40 reps.

Thanks

Andy-
Do you have any idea how many pounds the carbon will shave off the weight of the car? What would the old weight compared to the new weight be?

Thanks,
Steve

No idea yet. Our spaceframe only weighs 249 lbs plus panelling.

The preliminary design work on the carbon mono is done and we will find out soon.

Thanks

We had chance to get a few weights today. It looks like we will save approx 200lbs off the weight of our normal spaceframe car.

Thanks

Wow Andy!

That's a significant saving. Very impressive. I look forward to further updates.

Cheers

Yes I know. It means a standard car in road trim should be less than 2000 lbs or 909 kg.

I may build a super light weight for myself with carbon body and aluminium everything.

Could weigh as little as 1700 lbs or 770 kg.

Good point CZAN,

With only a 440 HP SBF the car should have a power to weight ratio equal to an ALMS P2 Porsche RS Spyder. :stunned:

Less than 4lbs per HP.

It is shaping up to be one wild ride!

Cheers,
Scott

Hey, nice effort on the Carbon mono! It has some nice touches.

The box section body hangers at the back, front, and the roll-over bar are these of steel or alu construction?

After reading the details on your aluminium version it states it weighs 1/3rd the weight of other aluminium monocoque chassis currently on the market. That is quite a remarkable feat, are there any specific areas you have managed to save large amounts of weight over theirs and of course the run of the mill tubular spaceframe chassis? Are both the aluminium and carbon mono identical in construction? How does the torsional rigidity compare to your spaceframe chassis?

Regards,
JJ

The front/rear subframes and roll over bar are all steel on both versions and bolted into position.

The rear subframe is bolted in to the tub and contains all engine and suspension mountings in order to spread the load evenly into the Monocoque.

The reason its so light is because both carbon and aluminium versions are constructed with an aluminiumn honey comb core material like F1 cars.

We have invested a substantial amount of money into this project in order to offer our customers the absolute best products at the most competative prices.

Designing chassis like this is very specialist and we have two ex F1 design guys on board just for this project. Load spreading is the name of the game.

The Ford J car had a very similar chassis and it only weighed approx 130lbs.

The skin and core materials used are measured in thous and not inches yet the combined strength is much higher with a massive weight saving.

Every time the overall panel thickness is doubled using the same thickness of skins and core material the strength is increased 4 times.

Stiffness figures are not in yet but its safe to say it will blow all other GT40 chassis out of the water.

Thanks

Help me to understand what I'm reading...

The tub is carbon fiber
The front and rear sub frames are steel

Do you have steel plates bonded in the tub to which the components attach?

Thanks

There is a choice of tubs. Carbon fibre or Aluminium.

The front and rear subframes are steel to accept point loads.

There are inserts bonded into the tubs to accept the mounting points on the subframes.

Thanks

Andy
 
Thank you Andy.

Since the the tub and front/rear sections are dissimilar metals, isn't there a concern that galvanic corrosion might appear? This is a concern since the frame is used as a ground which enhances the galvanic reaction.
