I agree- I love the creativity and engineering that goes into doing this. The Originality Police have lots of posts they can look at (in fact their very own forum!).

Cheers,

hey this looks familiar... is this an old cobra frame? Perhaps the best use for it.

how much easier/quicker will future frames be?

I have made jigs for every thing as i have gone along and my partner peter has been drawing everything as we go so we are ready to go into production straight away , but we want to get some test miles on this car before we start.

Cool. It would be great to have some real world hard data to quiet the naysayers (cornering G's etc)

saw this in the flesh on the DAX stand at Stoneleigh Sunday/Monday gone (I assume it was this one Gary? - don't think DAX had any other works of art on their stand

)

And as mentioned ^ , it really is a stunning piece of work to see. The rear wheels are huge.

Awesome work Gary, keep us updated.

been locked in the workshop doing the internal panals geting the shapes the same as the body is taking longer than i thought and then making paterns

Beautiful work, no carpet!, hell I don't think I'd put the body on it. Fantastic.

Regards.

I think that chassis deserves a unique engine- whats the widest engine that would fit? I'm thinking Boss 429 (about 29" wide I think) or 427 SOHC. Looks like there is room for the engine width as the upper frame tubes seem quite high, the valve covers might just slide underneath?

Edit: might have to move the one upright tube the exhaust snakes around?

we have built a simular chassis with a 454 chevy and like you said we moved the upright tubes and lostsome foot room but it was still very good for space , we can fit any engine as a one off for an extra fee .

the engines out again so i can line the trans tunnel with ally on the inside to show of the chassis

I have to disagree with you on this.

I have 275 18's in the front of my scratch built Cobra replica. I used C5 Corvette spindles and control arms with a custom manual rack. Also used C5 rear suspension and diff, (converted to take a drive shaft), C5 wheels and tires, brakes, LS6 with a T56 trans. It is VERY easy to steer. (everyone that tries it thinks that it has power steering), is 100% stable, even at high speeds on the track, and on the road at legal speeds and has zero tram lining. I use it as my daily driver as much as possible.

It is the front end geometry, correct parts, correct alignment, along with the correct wheel offset that effects these qualities, not the tire size.

is it possible to fit bigger tires if one wanted to? I.e. 265's or 285's? Any fitment issues?

yes bigger tyres can be fitted but they are not necessary

Gary

A couple of thoughts......"
What it would take to install power steering.......
What is your bump steer.....
What ia your Ackerman......

As you go to a larger tire and try to go fast with racing tires slicks......you will find that the steering gets very difficult ....

If you can move your rack back so there is a 10* degree difference from the steering arm on the upright......and ball joint of the rack..... the car wiil track around a corner with ease...

And on the rear ....can you rotate the upright a small amount to get the rear bump steer going in the right direction.
