I don't know what your background is, but I'm sure you are aware that this is a massive task to get this car up and running with the hyraulics, electronics and loom etc, maybe you should talk to Gould Engineering, these kind of projects are right up there street.
Good luck

a current F1 machine is certainly not a 1 man show to operate.So you need to get rid of most of the gimmicks methinks.

Just registered to say fantastic project, a man after my own heart :D

I bought a complete (less engine) Reynard 88D f3000 a few years ago to do a similar project.

As its a much more straight forward car, my issues are not so difficult to overcome. A DFV is slightly over my budget so mine is being fitted with a Cosworth RS500 YBD so it will have similar power to the original engine but easier to maintain. I am making F1 style sidepods and engine cover and already have a benetton floorpan and a set of F1 wheels, slicks and wets. I even have the daft idea of making it road legal once its shaken down.

Not long after I purchased my car Paul Stoddard had a clear out of his F1 collection and I still regret not snapping up one of those bargains, especially the Tyrell 019 rolling chassis.

I will keep checking back for updates as I have no doubt you will achieve your aims.

I have had a cradle made to surround the engine which then bolts to the gearbox adapter. My car uses a hewland FGB and the complete rear end bolts onto that, I am sure you could adapt such a gearbox/casing to accept your suspension pick up points.

I think without the engine and steering wheel and without the gearbox there are no gimmicks. Its basically a rolling go kart at the moment.

With a custom engine gearbox solution there should be no problems operating the car by yourself.

Good luck with the project. I have brought one (Tyrrell 017/4) back to life from roller status ( http://www.youtube.com/watch?gl=US&hl=uk&v=3HaYCqTrEQs ) seen here putting some temp in the tires, and am about three-quarters of the way through a pair of Tyrrell 018's. I can appreciate your task, though I stayed with Cosworth power to make the transition from roller to track easier. I was lucky enough to find a large cache of spares, so most of the unusual bits are at hand, but there is still engineering and manufacturing of small batches that gets done. No question, you dove in at the deep end, but driving these things will make you realize its all worthwhile.
I can recall the auctioneer at the Stoddard auction asking, when I bought the tub for 018/1, what I was going to do with it. I replied that I was going to put it back on the track, and you could hear the snickers in the room. What they didn't know was that I already had 018/2, and enough spares to come pretty close to putting this one back together. When we got the tub back to Southern California, there was evidence of repair. We sent it out to Boeing to see if it was structurally sound, and they gave it the thumbs-up (They have a test that's like a big sonogram for large carbon structures like, say, large parts of a fighter plane ). If it didn't pass, we'd have painted it up and hung it on the wall; it set fast lap at Canada in 1989, when not too many non-McLarens were setting fast lap.
So good luck and never give up. There are enough talented engineers out there to make this a reality for you, but chasing an original engine is the best (but hardest, I understand) route.

I'm in L.A., cars are in Orange. We really don't head for the historic meets. The preference that the HGP cars get vs. the newer cars is ...um.... well, lets just say we don't feel all that welcome and leave it at that. So I go out alone, where I don't have to please anyone but myself. The black 017 I've had up for sale; had it sold, price agreed upon, handshake, etc, only to head into late 2008 with radio silence from the buyer. Since then, the other 4 017's came up for from a racing school, and they have crapped all over the market for this car, despite it being absolutely perfect. (http://nelson-motorsports.com/1988_tyrr ... 20sale.htm ) Would like to sell the 017 to finish the 018's at a faster clip. The cars look like this:

But in the interim, we're doing what F1snake will be doing, which is fabbing bits that may be missing. In our case, its things like an airbox:

or front brake ducts:

There are a gazillion little things as well:

We'd be doing things a lot faster if a certain 019 owner let go of the 018 parts that don't fit his car.


As to where you could find a Honda engine, never say never. When poking around Peugeot or Renault-powered cars years ago, you could never get the engines or the electrics. Yet not that long ago, I had a fellow tell me that they might not be so unobtainable. You never know where or how you might get a chance at acquiring one, and sometimes it's just how you approach it.

Tim.Wright,

You are absolutely right, there's no gimmicks to worry about without the engine, loom ,steering wheel etc, and as you say, it's just a rolling chassis. The aim certainly is that we(me+better half!) will be able to operate the car without assistance.

Paul S & Ralt12,

Thanks for sharing your experiences with your F1 projects. Glad to see I'm not the only mad hatter out there!

Its going to be impossible to source an original Honda engine for my car. As metioned before, Honda retains or have crushed the remaining RA807E's. Even if it was possible to get one, I would not use it. Far too highly strung and awkward to live with for my needs. Of course originality would be nice, but for me, drivability is more important.

They will not have crushed the RA807E engines, the will probably have them in a sealed vault somewhere where they are in their sealed little boxes. Honda will probably have about 25 or more engines in that vault.

Just hope you can get the car up and running as quickly and trouble free as possible, whilst keeping it serviceable to your needs.

If you use the original engine you can kiss the simplicity of running the car goodbye. No doubt these engines are extremely tempremental with almost no flywheel and they need to be preheated with hot coolant before running.

I honestly think the H1V8 is the way to go. Its infinitely more practical, probably infinitely more drivable and possibly even cheaper than the F1 engine :wink:

As said before I fully support getting the H1 V8 as well.
I would go even with a modified turbo 4 cylinder from the said hyabusa if i couldn't get the V8. Same high rpm's so you keep your noise AND you can get the block on the street so it's cheap, and with turbo you can easily get over 400hp and much more torque than the H1V8. If the block breaks just get one off the shelf.

Even a honda 1000RR turbo might be fitting.

Right, enough talk time for some action.

I was bored this afternoon so Ive made a scheme in Catia with the H1V8. Looks like it wont be an easy fit so some 'engineering' is going to be required to implement this engine.

3DXML version of the CAD file;
http://www.box.net/shared/agnz2qq757
You need 3DXML viewer to see the file. Sorry I can't export as step since I don't have the STP1 license.

I have also made a short ppt file to explain the model.
http://www.box.net/shared/vdsa84q8qv

Bjorn, if you want me to make this model more accurate I'm happy to do it. It will of course mean some hours with a tape measure crawling about the floor, but I think it would be useful for your meeting with Hewland next month and also if your talking to Hartley. Let me know!
