Rear Engine Modified Roadster Build

[saltfever]

Thanks, Tony. How come you changed your avitar? 

[maguromic]

I changed it again, I couldn't help myself.   

[saltfever]

I guess I'll have to add mine. Not as good as yours though.

Finished up the updated windshield configuration.  Gained a bunch more room by shifting the windshield forward. The windshield looks a little off set, but the driver is shifted to the left a bit off center to clear all the plumbing lines on the right side.Tony

Tony---that thing is going to be so so SWEET 


what all do you have up front that requires so many or big pipes that require that much off set

Sparky, The tub is shifted about 2”.  The engine water tank has two 2” lines and there is also the fuel tank and the intercooler tank along with the cool suit tank up front.  Then add to that all the wiring running down that side. Good thing is everything will be in modules so servicing will be very easy.  Tony

"...servicing will be very easy..."

Yeah -- that's what they ALL say -- before.  Then it comes down to servicing the car in the pit -- all of a sudden it isn't quite as easy.

Nice looking race car, though.  I look forward to seeing it in person.

I sure like those pictures ?  What kind of software was used to create them...

We layout our cars with  graph paper and a few pencils,,,,

Your way looks better.

If think it will be easy, it just might be.  Kind of like Alice clicking her shoes together.   But I think you correct in your assumption.  I have yet to work on an easy race car.

We use Solidworks for most of the work.  We have several files that go back and forth with several of us adding to them. Three of the guys are working on cars at LeMans this weekend and have been gone all month. Tony

        Can't get any easier than that Tony.

It was don intentionally to show how impossible it is.  Armond AKA Rebelce was the only one that caught on. Tony

Finished the first run on the under tray and rear diffuser.  There are two tunnels plus the center short tunnel. It should make several hundred pounds of downforce at a pretty low drag penalty (probably 1/3 of the drag from the same downforce from a wing).  Just in case we need more downforce the center is designed to add a double diffuser in the middle.  When we CFD the car with a flat bottom several weeks ago we tried all sorts of different wing configurations.  The best one it liked was our bat wing that Steve designed.  It will be interesting to see how the new bottom will like the bat wing. Depending on what the CFD tells us it may see a few more strakes in the tunnels also.  Tony

Hi Tony,

I've been watching your thread and design process and it's simply amazing!!  I can't wait to see you guys building the components and putting it together. 

I'd be very interested to see some how to's along the way, us ameteurs need all the tips and inspiration we can get!

Steve, Thanks for the kind words. Currently we are machining all the suspension parts and I will post them as they become available. I also asked for some of the CFD screen shots for posting as well.  Tony
