The Project Singlecoil & Me Have Been Working On.........T

[TheDetailDoctor]

Well chaps, here's a rendering of the proposed design for a trackday kit car that we have been working on.

The design here is about 4 weeks out of date, but the shape is mainly unchanged, most changes are around the front mounted rad ducting as a result of some preliminary CFD I have carried out..

This is the first "whole car design" I have done and there are still a few areas in the coming weeks that will be finessed to make more elegant/address any CFD issues.

All CONSTRUCTIVE comment welcome.

I do have a slightly more up to date model of the body.

I'm also not personally convinced by the double-bubble fairing in front of the cockpit - apart from anything else it would make fitting a wind deflector more complicated (and fussy-looking) than it needs be (how about a single bubble with an 'aerojet' type venturi deflector, a la Lotus 49/Renault Spider?).

The intention is to be fully road legal yes.

I do also have some very rough ideas as to a body featuring a closed cockpit, Non of which I'm happy to share at this point.

That is one of the areas we have been thinking about. I've got many itterations of a single bubble, non of which I'm happy with to be honest, just tends to look like a blob.

Have you done the chassis and package design yet or are you going to work that underneath the body at a later stage?

There is a chassis yes, and suspension wishbones, even a basic engine/gearbox model.

Hi there.
You could break up the "slab sided" look with those curved vent arrangements, behind the front wheel and/or in front of the rear wheel. Do you know what I mean? Otherwise it looks fine to me. I like the idea of the Renault Spyder windscreen/ duct idea though.
See pic of SPIRE below.

Good god, that's the first time I've seen one of those, the two are quite similar.

The issue is due to the low top deck height & the height/width of the powerplant we NEED some width in the area of the air intake.

Here's a couple more ISO veiws. At least you can get an iead where we are heading with the rear end from here. The diffuser is a little crued at the moment & will be more elegant. The rear panel will be perforated sheet, similar to that use on the rear of an F360 to allow plenty of exit area.

There's going to have to be a small splitter up front too as currently there is an area of hig pressure at the front as a result of the air spilling under the nose.

The big issue I would have with buying that, as a road car, is the front rear overhangs. Whilst a big advantage on a track only car, on a road car it would be a liability in handling, road positioning, and damage terms. I suspect it would make a good track only car though.

If you look at any of the road legal mini Le Mans style cars, their overhangs are tiny. I think the design needs focussing on one area or the other. At the moment it seems to be too track focussed.

It is great to see another project though, I wish you all the best of luck.

ETA Is the design driven by CFD or is it a styling exercise / best guess currently?

First instance was to make a shape that was "visually acceptable". From there I have careid out some basic CFD, primarily to ensure there are no areas of high high/low pressure where we don't want them.

Certain areas, such as the angle of the front most part of the nose (was vertical, now laid back at a slight angle) are a direct effect of the findings of the initial CFD.

I'm afraid I have been unable to commit the amount of time I would have liked to commit to this project, I have a day job that I need to do to pay the bills. Initially I agreed to provide a pictorial reprsentation of how the car would look. I think I've gone way above that brief. Whilst I have been making some progress on the finer details of the project, it's been slow, but as it's apparently come to an end I'll waste no more of my time on it.

I'm sorry you feel that way, I wish I'd realised you were still working on it.

I'm not as of now, glad I was the first to find out!
