RobAndrews Posted December 2, 2005 Share Posted December 2, 2005 Hello Jay, just thought I'd say well done so far, it's inspiring. I met you quite a few months ago at Interpro when I took you out for a Sunday drive in my stock Sup and you took me for a roller coaster ride in yours. Top work you're doing. Rob.

Lucifer Posted December 27, 2005 Author Share Posted December 27, 2005 Here are some pics of my Internal parts I have purchased.

Lucifer Posted December 27, 2005 Author Share Posted December 27, 2005 Got loads of other parts, just got off the phone with a fabricator. I'm having a complete Ally underpan made in 3 sections. Yes you heard it right... A completely flat underside for the Supra. Was going to keep it under wraps but looks like it is a goer. Panel 1: An exact copy of the 2nd undertray below the sump. Panel 2: From the Cross member back to the Middle box area Panel 3: Middle to rear section. This will be made to take a 6" Exhaust and will have all the relevent cut outs etc and vents. After I have a prototype, ill look at the cooling aspect and get some vents and ducts stamped in. Got to get a few lugs made up to support it and keep it all flat. If I have time ILl also look into making detachable brake ducts too. Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 27, 2005 Share Posted December 27, 2005 A completely flat underside is nice, as long as it doesn't interfere with the airflow requirements of the various parts that depend on it. I see that some of the engine bay airflow will exit from the bonnet, so you can afford to lose some from down under. Will the exhaust be sticking out, or will it be shielded (and get hotter than expected?) Quote Link to comment Share on other sites More sharing options...

Will the exhaust be sticking out, or will it be shielded (and get hotter than expected?) Too true, the engine will overheat like mad without some radical cooling aerodynamic mods! Air flow from the water rad is part vai the front wheel arches and a mainly down the tunnel past the gearbox. Coolers WILL be needed for the gearbox and diff, too, as air flow past them will be neglible. You won't be able to run a road car low enough to get much flat bottom downforce, reduction in drag could be significant IF you can address the cooling issues. Under floor panelling needs a LOT of secure fasteners. IF it produces some downforce (correct rake and low enough and it will..) then it needs to be stiff and very secure.

Lucifer Posted December 27, 2005 Author Share Posted December 27, 2005 All well noted. I will have a look at the end result and keep you updated. Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 27, 2005 Share Posted December 27, 2005 Further on this theme, could I raise the general point that the supra's aerodynamics are neither primitive nor suboptimal, and if the Toyota R&D team could further optimise airflow underneath they would have already done it most likely. My appoach is first to make sure that I understand 100% why things are the way they are, by identifying and measuring them. Then study the alternatives that the designers had, and try to figure out why they chose the path that they did, what compromises they made and *why* So if I want to shift the balance in an other direction I know what to change and why (and how much perhaps) Studying the airflow of the supra's undercarriage at high speeds may be more complicated and resource-intensive than may seem at first glance. Fancy bodykits and fibreglass 'replacement' parts are fine for show-cars, but functionality is a whole different ball game. Quote Link to comment Share on other sites More sharing options...
Lucifer Posted December 27, 2005 Author Share Posted December 27, 2005 Ah well back to the drawing board, although teh first tray replacemnt should be goo though. Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 29, 2005 Share Posted December 29, 2005 I've said it before and I'll say it again. You really don't want to create downforce on a road car. Especially downforce that is particularly sensitive to ride height, such as that created by undertrays and "ground effect". You'll regret it when you go around a corner and hit a bump and suddenly lose a chunk of grip just as you're getting to the apex/exit. Remember, despite the extortionate taxes we pay, race tracks are generally a lot smoother than her majesty's highways. Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 29, 2005 Share Posted December 29, 2005 On the same note, sudden changes of road clearance could then lead to sudden loss of grip. That's how a certain F1 driver got killed (according to the Discovery channel at least) Quote Link to comment Share on other sites More sharing options...
