I'm hurrying as fast as my little brain will let me :-)

Wow OP,fantastic project. I wouldn't know where to start. Would you mind tell me the origins of the engine, what has been done(will be done) to it. Did I see two monster turbos on it? Has it been dynode . And what quarter mile are you expecting. I assume this will be a 9 sec car/150mph?
Thanks. Engine built by Geoff Page many years ago. We discussed what I wanted to do and the spec was agreed upon that would achieve that. The detailed spec is outlined in the first post. Bear in mind that this engine is now over 10 years old (but unrun) and the spec would be very different if built today. However, 520bhp back then is still 520 bhp today :-)

Only one modified RS500 T4 turbo I'm afraid.

I have my 1/4 mile ambitions, but I am keeping them to myself so as not to be a hostage to fortune. However, it should be quite nippy :-)

Hat off to you! This looks like it's going to be something wicked!

You putting super wide drag wheels on or keep it reasonably normal?
Thanks

As this is being built as a UK street legal car, road legal tyres will be used. They will probalbly be Michelin TB5s, but I will be also be talking to Pirelli at the Autosport Show at the NEC this month as they are the control tyre for the UK Time Attack series. The rears will be between 285 and 305 wide. The rims will be 15" diameter.

Just come up against one of those little challenges that you expect on a unique build. Started to sort out the centre console whilst the glue cures on the firewall. Cut the hole for the handbrake which worked out fine. However, a problem I had in the back of my hand reared its ugly head. I can't remove the console over the lever as it can't be moved forward in order to slide the lever through the hole. The console can only be fitted and removed vertically due to dash and roll cage.





Two solutons come to mind. The easiest but messiest is to simply lengthen the slot and cover with a removable plate. Quickest and easiest, but I don't tend to do quick and easy :-)

My other thought is to modify the lever so it is detatchable.

Any thoughts?

Ah, writing this has given me an idea. Remake the handle out of tube with a threaded section that can be unscrewed!

Carbon angle came out OK. A bit rough and ready but that is fine as it gives a good key for the glue :-)

Absolutely brilliant build.

I went for a full rebuild and light modification on my old esprit. Given more money, knowledge and balls, I would have done something similar to what you are doing.

Thanks.

Full rebuilds aren't cheap!

Over many years money isn't such a problem. Knowledge is gained as you go (quite a few things have bene done more than twice!) As for balls, I had a quick check and there are still two :-)

OP and plans to make the carbon work you are doing more structural? Or are you happy that the cage will provide all the additional strength in the chassis that's needed?

We use T45 to build (parts of) bicycle frames, great stuff - and peculiarly British (overseas everyone else seems to use 4120).

That's because they don't know what they are doing :-)

The cage has made a hell of a difference. However, as a chasses can never be too stiff (there are probably situations where some flex is advantageous) all the carbon parts are bonded to the cage and chassis wherever possible so they contribute to the overall stiffness.

Glued the top section of the firewall in this afternoon. Using structural expoxy adhesive so this will, in a small way, add to the tortional stiffness, every little helps :-)

The wooden resin mixing sticks were a perfect length with just enough springiness.

This will get very hot so will be faced with Zircotec's Zircoflex III flexible heat shield material. Bloody expensive but bloody good.

As you are clearly a fan of fastest and street legal, do you know about Andy Frost's Red Victor ?
