Spitsurfer65 Posted May 27, 2014 Share Posted May 27, 2014 New topic, new thread: I now have the Wheels aligned and the spoiler from Yorshire Triumphs fitted. The question is for even more down force: Is it an idea to fit carbon finns on the sides of the front just in front of the Wheels or is in just plain stupid? I have a friend making all kinds of things out of carbon and he can make bespoke finns... Debate, please :-) Link to comment Share on other sites More sharing options...
pomwah Posted May 27, 2014 Share Posted May 27, 2014 Based on the image, I think a deeper spoiler, (dam) would be the go. Try the "fins" by all means but you're still going to get a lot of wind (pressure) under the car, have you tried dropping the front a bit? Link to comment Share on other sites More sharing options...
Spitsurfer65 Posted May 27, 2014 Author Share Posted May 27, 2014 Hi Sorry. This is and old Picture. I have the New spoiler from Yorkshire Triumphs that is a lot lower. Link to comment Share on other sites More sharing options...
JohnD Posted May 27, 2014 Share Posted May 27, 2014 (edited) A favoutrite subject of mine! The Late Silverback was an aerodynamic experiment, that followed on from my earlier Vitesse, Old Blue. I fitted that with a deep airdam, as deep as race regs would allow, and with side skirts, ditto. When I built Sb, the idea was to further limit the air passing under the car, by putting the radiator in the back. Less air = faster air = less pressure = Downforce! No front radiator, no oil-to-air cooler - I used a Laminova, oil-to-water heat exchanger. But getting a rear rad to work on the track was so difficult that I never fitted the airdam to SB, I was always working on mods to the cooling. Eventually after two near disasters when internal hoses let go of their connectors and the car was filled with cooling water and steam (I was scalded, but my track day passenger only got wet) I called it a day and went back to a front rad. So, yes, I have experience from Old Blue, and from Sb, and to be honest, I think it makes no difference. A VItesse really is a Flying Brick, and I fear that despite its nice shape, so is a Spitfire. Full skirts, along ths sides and behind the rear wheels with a rear diffuser, perhaps. The way to tell would be formal testing, but no one has ever had a Triumph in a wind tunnel. Perhaps you can be the first? John Edited May 27, 2014 by JohnD Link to comment Share on other sites More sharing options...
spitfire6 Posted May 28, 2014 Share Posted May 28, 2014 Hi Sorry. This is and old Picture. I have the New spoiler from Yorkshire Triumphs that is a lot lower. Hi, Do you have a picture of the fitted spoiler? If so please post. Cheers, Iain. Link to comment Share on other sites More sharing options...
JohnD Posted May 29, 2014 Share Posted May 29, 2014 "Fins in front of the wheels"? You mean 'dive plates'? See: http://www.formula1-dictionary.net/canards.html These don't generate down force, but a vortex along each side of the car, to inhibit air entry under it, when you already have the airdam, skirts etc. John Link to comment Share on other sites More sharing options...
Spitsurfer65 Posted May 30, 2014 Author Share Posted May 30, 2014 Ok, JohnD - so no point fitting actually? Link to comment Share on other sites More sharing options...
JohnD Posted May 30, 2014 Share Posted May 30, 2014 (edited) I did fit dive plates to the airdam, on the outer corners, no pics, I'm afraid, ina futile attempt to mke the whole schtick work, but ..... I'd hate to quench your enthusiasm - a fully aeroed Spitfire would be, er, 'awesome'! Other people ahve gone alot further with the Vitesse, get load of this...

JohnD Posted May 30, 2014 Share Posted May 30, 2014 Thanks, Millstone, hadn't seen that! And that project was to do to a Mini what I did on the Vitesse, plus a diffuser. The gains were small, but I'm interested and gratified to find that in theory anyway I was going in the right direction! I did read Simon MCBeath's book on "Downforce" avidly at the time. Ho-hum, Silverback's gone to the Great Garage in the Sky now. JOhn Link to comment Share on other sites More sharing options...

If you don't have enough velocity for the air to generate down force create your own with sucker fans. Edited May 30, 2014 by motov8id Link to comment Share on other sites More sharing options...
JohnD Posted May 31, 2014 Share Posted May 31, 2014 (edited) moto, I did think about that! But a major complaint about the Chaparral and the Brabham BT46 that followed it into F1, was that it threw stones at following/overtaken cars. That, and the major advantage it had over them. I would have loved the second, but not sure I could live with the first, and the damage it would do to my racing friendships, let alone the system when in F1 anything damaged can be replaced between races but not out of my pocket! Air intakes were on the sides, just behind the rear wheels. I also thought of extra fuel injectors and an afterburner: JOhn Edited May 31, 2014 by JohnD Link to comment Share on other sites More sharing options...
SpitKseries Posted June 9, 2015 Share Posted June 9, 2015 Here is the air dam Link to comment Share on other sites More sharing options...
egret Posted June 9, 2015 Share Posted June 9, 2015 It looks like you can see tarmac through the air dam. If so an undertray will help the splitter work by directing the air above the splitter through the rad/engine bay and the air below the splitter under the car. N.B. any major re-direction of air at the front of the car could cause front end lift if there is nowhere for the air to go so test carefully!
