Just what the roadster needs

[spud69]

Got some pics below of a mold in progress for a new rear diffuser for the roadster. It's designed mainly to cover in the area under the diff cage area and stop the rear panel acting as an air brake. If it provides some ground effect then all the better.

It's got a bit more work to do but shouldn't too long.

[wylliezx9r]

Looks cool as, any idea on price and when it will be available ?

[Eternal]

Sweet i will take one off your hands when i order the rear tub.

Me too!!

[K4KEV]

Looking real good Andy;) ....might have to pop down and check that out, it's nice little details like that which will always keep SSC in good stead... especially ooop ere in N.E.R.D land:D

[Eternal]

Heh the next cool thing would be a fiberglass scuttle with window frame in 1 bit :D

kinda like this one. http://img862.imageshack.us/img862/4002/26953564.jpg

With an enclosed cockpit - i'll put that on the list......:eek:

Cheers......;)

[Eternal]

Lol not with the enclosed cockpit but just the window frame would be ace. Feel free to use me as guinea pig if you want :D Could also build a rollbar into the rear of the window frame same as in that pic. Would be kinda cool.

But on a serious note if you do make a window frame scuttle i would buy one. Also do count me in on the rear diffuser for sure.

[tkpm]

Impressive.

Me too!!

Me too in black :D,

was going to have ago at making one myself, not if someone else is going do it for me.

[Tatey]

Spud, will these work with an aluminium tub as well? If so i'll happily take one off your hands.

[leroybrown911]

I will defo be getting one of these when I get my bodywork, any ideas on price yet?

[vmax1974]

i will have one of them too

Finally something i know anything about

in order to get the ground effect you will need to break the airflow up by adding a vertical lip to start the air swirling towards the undertray then the fins speed the air up pulling the rear end towards the floor

[flyerncle]

Vortex generators,also fitted to aircraft wings !!!!;)

That could easily be added at this stage, i will look into it during having a few beers on Sunday.

[Deanno]

I was planning on doing a rear defuser out of carbon fibre.
any news on prices?

alsoSpud you have a PM

[vmax1974]

I was going to pop in this morning but instead i went to stockton to let real radio smash the wifes ornimental plates :eek: lol may pop in later

[cornishmaid]

Will this fit with the rear panel section that was made by Triton? Our car is fitted with the full Triton body panels which we purchased back in 2008, we had a few extras done at the time which Triton intended to put into production but don't think they did so it makes our car rather special.:)

This might sound like a daft question, but how fast does a car need to go to gain any appreciable effect from aerodynamic aids? I.E. Is there enough gain for road use, or is it more track related?

[vmax1974]

should have a small effect on the road but the real benefit will always be on track and on motorways and as spud said the rear panel will not act as an airbrake to slow the car down other things you could do is some vents in the top rear of the rear arches to unload the pressure build up in them that will reduce the airbrake effect too so should also help with fuel costs

Caterham spent a lot time and money in wind tunnels on this very subject a few years ago. I believe the model that uses the findings is the CSR version.

[cornishmaid]

So will the new panel fit the Triton rear panel?
Our rear panel is a bit different to the production version,we were assured however it fits on in same places and dimensions.

[spud69]

It should do CM, they are built to fit the same chassis dimensions and it will only need to tuck into the bottom return on the rear panel to fasten to the chassis with the rear panel.

You'll have to put up some pics of your car, it's always good to see other roadsters.

Andrew

[cornishmaid]

Thank you for that, we are in the process of putting a web page together showing off our toys and how we made our car so once it's finalised we will post the link up.

CM

[cornishmaid]

Just been on the phone to Mark who was Triton Products to ask him if anyone else had the modified panels like ours and he said yes there were two done in 2008 and both in Cornwall. He also said that the under panel will fit provided the mould has not been altered as he never altered that section of our rear panel.

We had a long chat about anything and everything, which was always the case while we were building our car.He always had time for a chat and helped with silly mundane things. I asked about his ban and the rumours he was getting back into the Kit Car scene but he just laughed and said yes on the car side of things and wouldn't say anything other than laugh about the other.

So I guess it's a case of watch this space really.

Me too, on both counts!:D

[cornishmaid]

You loose out too much having a windscreen fitted to this type of car, the wind buffeting is worse with a windscreen fitted than with simple aero screens. It's also like trying to push a door through the air as the screen tends to be quite upright and acts like a sail.

True, but tell that to my Mrs who's worried about her hair blowing everywhere and getting hit in the face by bugs! :D

Helmet, with a pink mohican on the top.

[Eternal]

still i def going the window way as want to get some wet weather gear made up. + with my engine i dont think the window will reduce the power much if anything it will probably help me.... :D

I certainly don't think power will be an issue in yours mate, you may need the extra stopping power! :D

[David_17]

Looks ace andy, well done and great idea. I too will be having one. Has the price been decided yet?

[spud69]

There is still a bit of work to do David, 2 weeks tops, but price won't be too extreme as it looks like they are going to be popular......:)

[Eternal]

allways good news! Keep up the great work Andy!

[flyerncle]

Fully enclosed CAN-AM style body next ?;)

[bobbyh]

Fully enclosed CAN-AM style body next ?;)

Sound like a cool idea. with f1 styel front wing?

have you thought about / making a fully flat floor and side skirts?

[flyerncle]

Will have to beat Andy with a stick to get him to do it and he is busy,I will talk nicely to him next time I see him .;)

No F1 styley just nice and aerodynamic with flat splitter under the front to give plenty of steering.

Dam you guys really know how to make a guy halfway around the world get really jealous with this extremely cool ideas and not being to get access to this parts lol

[Ricky]

Hi guys hi saturn would you have any progress pics on that rear defuser

[Ricky]

[Ricky]

Oops two posts my bad

[Richard Dryden]

rear diffuser looks awesome will definitly be needing one of those with body panels order

[cornishmaid]

Is the diffuser ready and how much are they?

[cornishmaid]

Any news on the diffuser?

[spud69]

Diffuser is nearly ready CM, had an awful lot on recently and it has taken a back seat but will be back to normalish next week and can crack on then.

[ozzy1]

I spoke to spud fri and he said they are in the process of producing one from the mold and should be on the website after the weekend for around the 90-100 quid mark.

It's finally complete Steve and we are quite pleased with it even though the fins where quite fiddly to cast. The diffuser description and some pics are here and also include a few guides to fitting:

http://www.saturnsportscars.co.uk/store/index.php?_a=viewProd&productId=94

The pics are of the first casting and show some signs of the pva release agent that was used to make sure it was free to be removed from the mold the next castings will be waxed for a better finish and the pics updated. The first casting is only 1 layer of 450 gsm matting and is still quite stiff when fixed but the remainder will be cast in 2 layers of 450.

All the Best.....Andrew

[rpjg1975]

Looking good there andrew, well worth the effort. Will go like hot cakes i expect. Just gotta see if i can fit one to an ally back end when i eventually get to that stage. Well done and keep up the good work:)

Good job Spud.

Don't take this the wrong way but you should correct the discription on the website, "to prevent are circulating in diff" now I know it's "air" but somepeople can be an ar**.

[shh120m]

looks awesome, il be having one, once iv got a bonnet!

[spud69]

J

Cheers Jimmy, the error of my spelling has been corrected.

BTW "discription" is spelt Description.......:p Couldn't resist it.

Took the car out last night and it seems to work as intended, the car seems more stable at higher speed and certainly pulls better from 60 to 100mph - quite noticably, and braking at speed is a bit more stable. Can't speak about downforce but it wasn't really intended for that will have to take it on the track - next week hopefully, Teesside track booked for race car setup......:D

Don't really want extra grip on the rear though as there is already plenty and would have to increase front quite a bit to re-balance the car.

Regards....Andrew

[rpjg1975]

Obviously the 60 to 100 test was on a private road as you wouldn't possibly be doing that speed on public roads officer! ;)

How would the open sides affect turbulence? Would it be an easy thing for someone at home to fill in the sides if it requires it?

CM

[bobbyh]

have you got a flat floor under the engine as this is another place that could give a not so nice air brake.

[spud69]

CM

If you read the description M it mentions the open sides and some people may prefer to fill them in depending on individual taste and pieces cut from side panels could be used. Tried mine last night and all was fine, it may circulate in from the sides a bit but it's 95% better than it was. Certainly more stable at speed since there is no air blowing around in the rear area.

Bobby the engine bay under floor is open but this could be covered in ali depending on peoples choice, the tray is not really to provide ground effect but mainly to enclose the rear area.

Andrew

[shh120m]

You wouldn't want to get air Bourne on the crest of a hill with a flat plate under the engine bay, remember all those old f1 cars flipping over backwards?:eek:

[K4KEV]

would probably suffer from overheating.... all that hot air has to go somewheres, both from the rad and block and possibly intercooler

[MarkB]

There are ways and means to skin a cat and keep it cool as well:D

[Tilly819]

hi all

spud, how have you resolved the problem of the rear lower wishbone being lower than the lower chassis rail, i was looking at making an undertray for the rear of mine and found that the lower wishbones were in the way, and as such when the rear wheel is in full drop it would hit the top of the undertray ?.....wonder if my shocks are too long?

[flyerncle]

Dont quote me on this but the travel is very little and there is no issue with it hitting if built to book spec but you need a 25 mm spacer as spud suggested.

[spud69]

Sorry Tilly i missed this,

Haven't found it to be a problem once you have your suspension and ride heights setup, the only time it is close is when the car is full jacked up. As Paul said a 25mm spacer is also used under RS3 to lower the tray to the floor level. If it is found to be an issue then the side can be trimmed to allow the lower wishbones to move past the undertray.

Hope that helps....Andrew

[flyerncle]

All we need now is a little chin spoiler for the nose cone......;)

[Tilly819]

^^

already on it, i made a small splitter for the front already but it needs lowering and a small diffuser putting behind it, made my own ally diffuser for the rear over the weekend, looks a bit Heath Robinson but bloody hell it works. il try and get some picks up soon

I had a good blast out in mine yesterday afternoon Tilly and the car now comes alive in 4th gear above 70mph, now gets upto the ton before you know it. Got a track day on Monday to so will give it a damn good thrashing then......:D

Well chuffed with it.....Andrew

[flyerncle]

I have seen some small wing type thingys on a nose cone at a race meeting on a seven type.

The idea I had was a spoiler/wing under the front of the nose cone.
