Title: Rotary go kart
Post by: baloo on October 28, 2020, 06:43:29 PM
hi guys
    bit of a long story  but i inherited an Rx8  and dident really need another daily driver but wanted to do something with it, l like the way the front and rear subframes detach carrying all the suspension with them  along with the power frame linking the front and rear (almost) solidly
anyway it looked a good candidate for a  bit of a project soooo....   go kart for the back lawn was the answer   not really interested in making it road legal   ( well at this point anyway )    first thing i did was to drain the fluids then roll the car on its side and weld a length of box section from  front to back joining the front subframe to the back subframe making sure that they could not move in relation to each other, i relise the power frame should be doing that but if the engine mounts are shot then it will flop about like a floppy thing  :)    while it was on its side i removed all the nuts that hold both the front and rear subframes in place disconnected the steering etc   but left the top shock absorber mounts connected so i could gently lower  the car back on to its wheels with them all crashing out to the floor before i was ready,  once back on its wheels i undid  the shock top fixings   so i could just lift the body off leaving the complete drive train on the floor with the subframes locked in their relative positions to each other ....
so then the decisions start to have to be made......     looks very long    so should i should i shorten the wheelbase   etc etc

Ha ha love it
 I bought my 7 engine from a lad who used to race a rotary engined go kart
It was very quick .
Not that that’s relevant at all to what your doing

well its a bit of fun   and passes the time since work has vanished  for now


looked a bit long at the original 106" wheelbase

(https://i.postimg.cc/9XqfpbjK/rx2.jpg) (https://postimg.cc/jCtKqz24)

something around 89" wheelbase seemed a good idea   so i took 17" out of the power frame

so being new to rotaries  i have lots of questions ,   i see thee is an air pump that seems to push air into the exhaust manifold  whats this all about and can i delete it    dont need this cluttering up my engine bay  ?
what else can i delete there seems to be millions of vaccum hoses criss crossing the engine ?

and are there any other options for inlet manifolds ?   not looking for more power   i want to get my bonnet line as low as possible, altenator looks it  will relocate to where the air con compressor usually lives   but the throttle body still sticks up in the air     i have loads of room running back down the bellhousing and on to the gearbox   it would sit nicely there

 that power frame is  such an irregular shape its hard to shorten it neatly,

(https://i.postimg.cc/m2DXD8wg/fggg.jpg) (https://postimg.cc/LhcBQkwc)

its also full of lumps of steel, so whats all that about then ?  some sort of vibration damping ?

(https://i.postimg.cc/PJf614nK/ffg.jpg) (https://postimg.cc/TLSq6nwW)


anyway i removed 17"  from the power frame  and glued it back together temporary  as i am pretty sure its going to have to shortened again as when i sit in the seat the gear lever is to far forward  and wants to come back 6" or so

(https://i.postimg.cc/Vv7KgCYw/ffgg.jpg) (https://postimg.cc/MfQ0KXM3)


im going to run a manual steering rack so moving the engine back will help taking some weight of the front wheels reducing the effort required to turn   and also it will add  more weight  over the back wheels   which might be a good thing as i can see traction problems ahead
the other benefit of moving the engine and box is it buys me some space up front   should this engine give me any trouble i can switch back to a piston engine  ::) ::) ::)

You can get rid of the air pump and blank it off.
No doubt you can get a different inlet but it will be costly .
Not sure anyone has relocated the alternator but it’s done on an REW swap so would have thought so providing you can make a bracket

Hi Mr Spiller
                alternator looks easy enough   but unless i can get  get the inlet  manifold and throttle body lower  theres not much point,
will take the manifold off over the weekend and investigate, but me and costly dont mix well lol
air pump already in the bin ....

thanks Andy

Excellent project.. But i would once happy get that prop ...or get another properly shortened and balanced by an axle shop. If it come apart and flails around it will cut you in half. I shortened the prop in my rx8 powered westy and the prob job was done by chards in Bristol forcabout a £100.00.

agreed  im quite fussy about what gets near my butt  and the thought of a prop doing 10,000 rpm making a bid for freedom dosent appeal at all
will buy a new prop when i know exactly how long it is

so  can the mobiliser be written out of the ecu  and if so  who does it ?

thanks boosted  i should be on the wiring in a couple of weeks or so  will give you a shout...   i did play with an mx5  and was going to make a chassis but in the end just chopped everything i dident need  to make it run  off it,  got quite luverly with the lack of weight,  trying to keep it out of the herbaceous border and on the lawn was  testing indeed

how strange is it that the welding gas always runs out on a sunday morning when you cant go get a refill   :dontknow:
so that slowed things up a bit,  well a lot really but hey hoe its the way it is,   i cut a few pieces and tacked then in place and made some floor templates out of plywood so as when the time comes to make the real ones i have something to draw round   :13:

          can anyone tell me what the standard spring rates are front and rear ?    i have 2 broken coil springs and i may as well convert  the shocks to coil over so i can fiddle with the ride height,  ive done plenty of front struts     but never a rear    any reason it wont work on the  rear shocks  ?

   well not much progress this week, a few jobs appeared  so thought it best to earn some money while the chance was there as i can see it being quiet for sometime,


the standard RX8 rear silencer seems to fit ok just need to rotate the tail pipes round 90 deg    all doable

(https://i.postimg.cc/c4BVVWYz/qwqwq.jpg) (https://postimg.cc/Tph7DZtj)

can anyone see any issues with using an lpg bottle as a fuel tank  ?  its robust  and its adding weight  over the back wheels  which i think is good as i can see traction problems ahead   ::)

(https://i.postimg.cc/Z5h7t6zP/bbbb.jpg) (https://postimg.cc/nC0YqjzM)

i wasent planning on much in the way of body work   but i found some wheel arches that sort of fitted  and experience has taught me that you need front arches at least .....    the rear wheels will fling mud sure but its the guy behind who's got to deal with it lol ,,  where as with the fronts  it comes your way  ::)

Walbro 255 cheap enough. However...the rx8s fuel pot contain the pump and internal fuel pressure regulator. You really need that or you gonna have to fit an fpr and run a return line.

ok will investigate the  adaptability of the stock pump, its still in the tank which i kept  i discounted it because it dosent look deep enough to reach the bottom of my ( lpg ) tank   not having seen one out of the tank i dont know if i could extend the pickup pipe down another 8 " or so

Great that this is coming along. (love the mudguards)
You obviously have experiance from the other car, but seeing the tank, if its not foam filled you will need a swirl pot and then as Jon says just a Walbro 255 pump

did you use an RX8 pump in an alloy tank ?   if so how did you hold it in ?
Title: Re: Rotary go kart
Post by: boosted on November 23, 2020, 06:02:13 PM
You tank the hole fuel pot out so internal reg and filter remain..that can be seperated to allow suction on bottom tank by lengthing with piece of alloy or suchlike. Electrical wires lenthen and pipe to outlet .
Tricky bit is cutting whole and welding on studs and making a gasket. Holes can be drilled for said studs on outside rim of fuel pot.

so you drilled new holes in the top flange of the pump and bolted it to tank ?  thats what i was wondering about or whether i had to use the screw down collar which would mean i had to make  up a new screw thread to weld onto tank

hello  boys
             i had a bit of an enforced break  the workshop floor was needed for a real job and i was evicted while it was going on lol
still ive got my space back now  and pressing on, im setting up ride heights and need a couple of measurements off a standard RX8 sitting on level ground,  first one is the gap under the front subframe to the ground at the front edge by the steering rack ,  and the second is at the rear to some fixed point on the subframe so i can mimic it  ,  or  the diff input flange to the ground although thats a long way under to reach i guess

anyone ?

thanks andy

Difficult for me to measure my 8 as my drive is gravel. But I still have my 3D cad models of all my subframe suspension pick up points from ground level if that helps ?

Morning Andy, now ive ventured into the shed and the hamsters re spinning in the pc I can get some dimensions from CAD.

Just as well as its snowing here in Worcestershire, so dont fancy rolling on the floor.

Below is an overview of my chassis accepting RX8 suspension.

A similar concept to yours but for a different purpose.

Mine has been calculated from the floor using stock RX8 wheels, and has been set up so the centre of the diff shaft holes on the back allow the drive shafts to be completely horizontal at ride height.

Also the steering rods on the rack are set so they dont have any bump steer.

I dont know how critical to want to be but my CAD is set with stupid decimals tolerances.

So for clarity, Front subframe, bottom arm pivot point on the front mount, hole centre is 172.5mm

Rear subframe, rear bottom arm pivot point, hole centre is 172.25mm

I hope this helps?

Good luck with the build, keep the thread going  :13:

These days the beautiful people of lozells and the Black Country flock to stourport in the summer. Clogging up roads, fighting with the local gypos and then leave their chip wrappers behind.
The high street is a wash with kappa tracksuit bottoms, Burberry caps, and sovereign rings.

Nice place licky hills.
