OK automotive ADD is striking big time today (today I have asked about the MG Magnette vs 1300 and Triumph saloons) but I just watched the Shell F1 commercial posted in the off topic section and now I am wondering how hard it would be to build an old F1 replica locost style.

I've been pondering how much fun a single seat F1 style locost would be for a while myself.

Pretty easy as they were built in much the same kinds of shops as the average locost builder. The original builders would be really jealous of mig/tig welders though since most frames up to the 70's were brazed. Probably the hardest parts to sourcewould be the transaxle and the uprights.

Unfortunately, we have pot holes around here that'll swallow an F1 car up, tenfold.

wouldn't be hard at all, gearbox out of an old Audi, or perhaps a flipped Hillman Imp gearbox, if you can find one? the Imp 'box would let you use a Coventry Climax-derived engine, which were quite popular for formula cars back then. uprights, just use miata uprights or maybe rear uprights from a UTV? that might be a bit more beef than you really need, but I doubt that the cornering forces a '60s F1 car could produce come ANYWHERE close to stressing that upright the way off-roading would, especially if airtime and high-speed driving over the rough and chop is involved, so it's fair to assume you wouldn't manage to break it any time soon

As far as powertrain..

There is an adaptor to mate up a ford 302 and a Audi Gerag transaxle (90*) which an take about 400hp (which you could build a 302 for easily)

Add bundle of snakes header package and a velocity stack intake...

The No 13 car there uses a chevy 5.3/porsche transaxle

Like this? In New York it has to have headlights, turn signals and fenders. YMMV. There was a local that made a Modified Dirt Car street legal, I was coveting the car when he came out with a bag of groceries. It had to sit on the floor between his feet.

I want to build something more along the lines of this for the street:

Make it a 2 seater.

In the UK I've actualy seen old firmula cars with fenders and lights added then registered for the street. Not cars built to look like old firmula cars, but actual cars. You used to be able to register almost anything there as long as it had minimal street equipment. Things are a lot tighter and a lot more expensive now though.

Same here... although some sort of roof might be nice.

These just look so dorky/poser to me. Same way I feel about CanAm Spyders.

I'd rather just have the locost. There is room for a lady friend, or beer.

What specificaly is this? Looks like late 60's small boar sport proto. But it just has perfect balanced lines, very nice.

So how small a fender can I get away with? I guess making them easily removable would be a good idea.

Given the number of hot rods that I see without fenders, I'm guessing it'll depend on where you live.

In reply to Adrian_Thompson:

Forsgrini sports racer. Made by a couple brothers in or near Seattle back in the day. There is some info on one of the sports racer history sites. This particular one vintage races. I think there is just something so right about the shape of it.

I've always wanted to do this with an old Farmula Vee. It's all done except the fenders and lighting.
