It's getting there - Rx-8 based roadster
 

Well its getting there, haven't had much time over the last month to get on with it but once i've decided on the rear hubs it will be rolling. Can get on with the braking system, hydraulic clutch, cooling and exhaust. Electrics last since this will be the biggest headache, rest should be pretty straight forward. Not sure where to get the bodywork from though.....;)

Quite pleased with it so far, engine fits a treat and will just fit under the bonnet once i've removed most of the intake gubbins.

I've attached some pics so pleasant looking........AndyH

Fantastic stuff there Andy
 

You look to be making good progress with that project :)

Going to be awesome when completed, I am a very big fan of the RX8 engine :cool:

Sure some bodywork will turn up from somewhere .... Might be a good excuse for a bonnet with a full length power bulge ;) :D

Very nice good to see more engine options :rolleyes:

What sort of power will you get out of that ?

Thanks Andy / Ronnie,

You can get 260hp from a remapped stock wankel engine but going for a conservative 240hp giving an ass kicking 460bhp / tonne - hence the RW460. Want it to be on the road by the new year, pro-plus ordered....

Cheers....AndyH

:eek: :eek: :eek:

Have you made any mods to the chassis to take this sort of power
I thought the chassis was only able of around 200bhp before it starts to twist?

Its got some extra cross bracing in Andy but also is made completely out of 2mm thick box section rather than 1.6mm. The 2mm box gives a lot stronger and rigid chassis and a lot better, stronger, welds.

You are correct about the Haynes chassis but this is more of a disclaimer for Haynes and when you compare the chassis to other cars taking similar power the Haynes design is as good as if not better than these.

Cheers.....AndyH

I expect you'll have some dopey old fossil from the far West of Cornwall wanting to visit Saturn for a ride once it is on the road :) :)

Better still, visit one of Saturn's track days :eek: :D

Be good for me and Handy to see you again Ronnie, don't worry though we've had plenty of dopey old fossils here over the year.....;)

Cheers....AndyH

That looks good Andy,

I will be over for a demo ride w2hen it's legal :)

:D Does that include us? "Hinge & Bracket" :D

The RX8 is looking great in the Roadster chassis, can,t wait to get it on the track :cool:

cheers
andy

You love a challenge ! Nice one :cool:

Looking good, front wheel alignment looks a smidge out though :p

It's looking good Andy! Looks much different to when I saw it on Sat.

A quick question with regards to the rear wishbones as I am currently welding my suspension brackets into place.

On page 73 of the book it mentions that the cross brace of the lower rear wishbone should point from the outside rear to the inside front on either side of the car. I was looking at your pictures for inspiration as to what this should look like. And from my interpretation it looks as if your wishbones are on upside down? Please correct me if I am wrong, as I am trying to get it clear in my mind while I go about putting everything together.

Right ive managed to confuse myself even more. My engineering sense tells me that the wishbones should be installed the way you have them as the force will mainly be acting to push the wheels rearwards, this agrees with the cad model in the front of the book.

However the picture on page 74 makes things even more confusing as it is the other way (the way I've interpreted the description).

Ahhh the rear wishbone debate....

I think the book corrections section has that in it.

I have taken the same approach and thoughts as yourself Tatey, the forces on the wheel traveling forward are transmitted from the front outer of the diagonal to the rear inward for the lower suspension arm. Seems to work fine for me.

Hope that makes sense......AndyH

I have seen them cross braced.
