Gaz Walker Posted December 6, 2006 Share Posted December 6, 2006 The Supra is circa 1500kg, what would the minimum weight you could get a Supra too for this type of thing, I'm talking fully stripped of any non-essential & carbon wings/doors/boot etc? I think 1100kg no problem at all... Gaz. Link to comment Share on other sites More sharing options...
Gazboy Posted December 6, 2006 Share Posted December 6, 2006 I think 1100kg no problem at all... Gaz. ...and if you put the engine back in? Link to comment Share on other sites More sharing options...
jevansio Posted December 6, 2006 Share Posted December 6, 2006 I think 1100kg no problem at all... Gaz. I guess that last 100kg to get it under 1 tonne would be a real PITA then Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 6, 2006 Share Posted December 6, 2006 So, to put it simply, it's not cheap then Chris! What do you reckon a good budget for the Supra would be in getting one prepared for something like this then? Top off the head figure I know, but any ideas? Thinking I could re-mortgage my parents house. Starting from scratch and paying someone else to prep an as yet to be bought car, about 50K Buying a car someone else has blown a big sum on, about half that. All out winning car with paid driver, from scratch, about 100K Link to comment Share on other sites More sharing options...
kosmic Posted December 6, 2006 Share Posted December 6, 2006 I can supply these fully adjustable suspension components for the Supra. If you'd like more details please let me know, they're not cheap but would allow you to fine tune the handling for your needs.

Lucifer Posted December 6, 2006 Share Posted December 6, 2006 I had more like 50k+ in mind Gaz. Thats about right. Link to comment Share on other sites More sharing options...
Gaz Walker Posted December 6, 2006 Share Posted December 6, 2006 Thats about right. We can easily spend 100k on a Supra no problem at all... there's just not many people who will! Gaz. Link to comment Share on other sites More sharing options...
Wez Posted December 6, 2006 Share Posted December 6, 2006 What a cool series, doesnt look like you need to do much to race either. I guess to be competitive you would need to spend a far amount on suspension and prob a small single. Link to comment Share on other sites More sharing options...
lucasl Posted December 6, 2006 Author Share Posted December 6, 2006 Right, thanks for the responses, nic those parts look good will be looking into them shortly. My knowledge of building something like this is pretty limited so any help and ideas would be greatly appreciated, especially from Chris Wilson as he looks to have very good knowledge over this sort of thing. I would love to finance a team to help me build the car but there is no way I can afford that at the moment, lol. As Wez said there is not much needed to compete so I will add to the car as my budget increases. As i said before the chassis and suspension is my main area to focus on and this is where im starting. Any ideas on how to remove as much weight as possible from the front, already relocating battery to rear and was thinking about relocating radiator to rear. Maybe removing power steering system, Ive heard of the alternator being relocated to the rear but I don’t know how it would work from there? The roll cage I am thinking of will be a 6 point cage with cross door bars as I have already mentioned and a cross rear bar, im also thinking of front strut tower bars connecting to the roll cage by going through the bulkhead, any other ideas for chassis strengthening? Depending on wheel size (width) I might need to ‘tub’ the front and maybe rear arches. Im going to try draw the cage design on solidworks ill post it up when it’s done. The Time Attack is a single lap run from a roll on practice run so setting higher boost for the run is an idea 400 to 500hp would be an ideal figure to start with I would guess.

Nick Posted December 7, 2006 Share Posted December 7, 2006 I was at the Tsukuba circuit in Japan today for the super lap battle, i.e. time attack. There were some impressive cars there, R32's, R33's, R34's (including the Mines GTR), RX7's,, NSX's, Imprezza's, Evo's etc but not a single Supra, except for one chaved up abortion in the car park. The Amuse Supra has proven itself on the circuit, guess they're not interested in competing. Christ did these things go, I'll post some pics up tomorrow. Good luck with the project, be really good to see a Supra compete. Link to comment Share on other sites More sharing options...

Why create your own roll-cage when there are plenty of off-the-shelves available from companies like Carbing? Link to comment Share on other sites More sharing options...
Thorin Posted December 7, 2006 Share Posted December 7, 2006 Move battery, junk aircon. Don't realistically think there's anything else easily doable to remove weight at the front. I wouldn't get rid of power steering. Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 7, 2006 Share Posted December 7, 2006 Why create your own roll-cage when there are plenty of off-the-shelves available from companies like Carbing? Because those cages won't have RAC MSA approval, if you are caging a car you might as well make it UK tace legal. Most of the Jap stuff is "bling" and not weld in. Bolt in does bugger all for structural rigidity compared to a weld in cage. Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 7, 2006 Share Posted December 7, 2006 For 2 laps just remote start the car off a big battery and have a Red Top 40 to run the car, no alternator needed at all. Rear rad is impractical as you would need wind tunnel testing to get air through it complex ducts, or a massive, heavy fan that draws mega amps. Stick with stock rad, stock viscous fan and stock shroud. I think no PAS would be too much, OK for a drag car, but even my Skyline (1350 kilos) is dreadful without the PAS, I couldn't live without it, even on track. You should be able to get 150 kilos out of the car if you try. More if you go for carbon doors, which will save a massive amount as the stock ones are hugely heavy. If you don't need lights just keep the lenses for appearance and drag reduction. Ideally the engine wants to go back about a foot, but that is major surgery and expense. The stock flywheel is massively heavy, you will make a big difference with a small clutch and flywheel. The diff is also hugely heavy, if the budget allows run an alloy cased diff, but again, it'll be quite involved. The electrickery and loom weighs a ton, bin as much as is not vital. If you want carbon doors that are indistinguishable from stock I can get them made, I have some for my Skyline and they are a work of art with full interior shells that take all the stock fittings, if required, and they weigh 2 kilos each, undressed, and 5 kilos with lexan glass in them and hinges and latch. Stock ones are 60 kilos.... Link to comment Share on other sites More sharing options...
Ark Posted December 7, 2006 Share Posted December 7, 2006 I assume your carbon doors are somewhat better than the Seibon offering? Probably costing a pretty penny too? Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 7, 2006 Share Posted December 7, 2006 Never seen any of the Jap ones, I got our carbon guy to make the moulds and do them, and even he was pleased with the results. I'd post a pic but my camera is knackered. To do more of these would be about 1900 the pair, but doing the FIRST set for a Supra would be at least double that, as the moulds are complex.

Angarak Posted December 8, 2006 Share Posted December 8, 2006 Not trying to do CW's carbon man out of work, but I think my mate could knock out a set of carbon doors (and at a push maybe the moulds too) for less than £1900. My mates website is in my sig - he's done doors for other race cars. His composites are not vac-formed/auto-claved though (like F1 composites), he uses the wet layup technique.

blitz supra Posted December 8, 2006 Share Posted December 8, 2006 I expect that everyone here has heard of the the Time Attack racing series, it might sound like a crazy idea but i want to build my supra and race it in this series, unless i can be convinced otherwise that the supra really isnt the right sort of car to turn into a race car. I know its not the best platform to start with but i believe with the right work done to it it could be a serious contendor + I have an ideal supra to start with 93 tt 6spd. What do you guys think Here is the time attack site. http://www.timeattack.co.uk/home.asp So you'll know Lex then ( but who doesn't !!) you'll have your work cut out keeping up with the big BHP Skylines involved in this Link to comment Share on other sites More sharing options...
