OK seeing as SWAT is nearly coming to a finish, I thought i'd better get my next project lined up so I can start collecting parts...

If anyone saw the top gear episode where they tested off road machines they'll see what i'm after. A REALLY fast offroad kart!



I've begun by buying abasic chassis off ebay for 100

I'll then be needed a good sized motorbike engine to keep the power to weight ratio good

Hopefully will look like this when done:

I had one of these when I was younger on the farm, a hell of a lot of fun, but got rid of it in the ned as it was too dangerous, my cousin rolled it, put both arms out to steady himself and they both promptly broke...

We clocked it on the airfield one day with dads car and it would reach 90mph easily, a lot when you are that low to the ground and are only 14!!

Scouse Monkey
11-02-2006, 22:06
best get em made properly as you want proper bends that dont cause bore reductions.

then again it is not that important as you have too much power anyway and want something cheap and easyt o replace if you bend it!

may I also suggest some triangulation on your lower side pieces next to the seats and along your legs. And some in the front suspension box.

Oh and some small verticals in line with the ones about level with your knees in the lower part in the large side window triangle up to the top frame.

04-03-2006, 00:15
I know the model is a rough, but i just wanna add a few suggestions.

The triangulation at the side needs to go to the opposite corners so that it's in compression not tension then have one going down to the front lower suspension mount, put a piece between the rear shocks, and some more strength to the roof.

See pic

http://i23.photobucket.com/albums/b382/AndyA-UK/11.jpg

Other than that, it's gonna be fantastic :D

Scouse Monkey
04-03-2006, 01:03
few more changes. Halved the effective length of the side beams. it is now potentially a bit over engineered but any members in tension (eg the 2 side diagonals maybe) can be made out of thinner tube. also dont forget to fillet important corners on the roll cage. Roll protection is my main concern with your design. Also, there is a large unbraced rectangle behind the seats but i assume the engine sits in there. Make sure if it does break off then the engine doesnt hit the passengers in the backs of their heads.

I would offer to do a quick FEA model in nastran or abacus but i dont have the time.

If you sent me some dimensions and load estimates I could see what i can do but no promises. I have 4 hours of teaching FEA on tuesday so i may be able to grab a PC and kill a bit of time knocking up a model.

James
04-03-2006, 01:21
will it not accept a 3ds model?

thanks both of you - 2fast those were the changes i had in mind - and yes the shocks need a pole across due to the angle of them

I will obviously strengthen up the chassis with extra fillets as necessary - main thing is to get the bulk built and then see how to go from there...

James
04-03-2006, 01:39
OK which of these? second is obviously lighter but first has a nice look to it...

Scouse Monkey
04-03-2006, 02:00
i thought about your 1st design but i get a mechanism feel to the whole setup - ie if you land on the roof then that entire front section will flatten.

its all about making bars as short as possible.

I tell you what you do need - a short diagonal from the upright at the back of the ****pit to the top bars.

Scouse Monkey
04-03-2006, 02:00
dammit! i am not allowed to say co-ckpit! :lol:

Scouse Monkey
04-03-2006, 02:02
you may also find you need to bring the roof line forward. when seets start defelcting and heads with crash helmets bob forward you may not have enough clearance.

Scouse Monkey
04-03-2006, 02:04
oha nd 1st design will making getting in and out difficult. design 2 is a typical co-ckpit setup.

i cant see 2farts being able to get out in a hurry if the engine catches fire :lol:

James

winx
06-03-2006, 15:51
what sorta specs are you aiming for winx?

not exactly sure yet, need to get it home first... I can get an engine from a scooby wrx for it basically for free and apparently I can get that to fit fairly easily. The other option is a porsche gearbox and engine, which I also happen to have at the moment... I reckon 250hp should be enough for now, nothing mental:p :boxing:

Scouse, again need to have a good look first but carbon is certainly an option, headlights are staying as I like them, all other lights will be changing though. Green seats have already been sold to a chap at work with a caterham. There is a set of recaros at work that are going begging but not sure if tehy will fit or not... possibly too wide.

On the other hand, keep it for the summer, have some fun with it and then move on to something a bit more serious, possibly to complement my offroad racer:wink:

James
06-03-2006, 15:55
trouble is your wasting most of that power with the weight of engine + gearbox, whereas I can lift my 155hp+gearbox singlehandedly. I suggest you get a nice turbo busa in there, that would shift it!

If the seats are not suitable for you I might be interested! allthough I don't imagine they'd fit mine if not yours....
James

winx
06-03-2006, 16:08
well that is a thought, to be honest need some weight though for some traction. Had a go over the weekend in a mates rwd mini, had a 400hp cossie engine in it, and was completely useless, no grip whatsoever until we put 4 breeze blocks in the back, then you could get some semblance of grip!

Thinking about it want to try and keep to the 'family' a bit so looks like the porsche option...

James
06-03-2006, 16:22
sounds like fun - keep us updated :)

Scouse Monkey
06-03-2006, 18:34
Winx i approve of your plans.

the engine will be sweet and it will be quick. motobike engine have no torque - unlike the scooby engine. that buggy will be heavier than cloudys or a lotus 7 and it has pretty big wheels so you will benefit from the torque and tbh will have more useable power (as i am sure you already know).

Fingers crossed the seats will fit and as for the lights...bah..they are fugly. Go for some IR lights and use some cameras for seeing where you are going - stealth buggy :D

You need some cooler alloys. hmmmm what hubs are you using?

Scouse Monkey

you going with the original cars offset? probably wont matter for an off road car. i assume you are not getting this thing SVA'd so you can put it on the road.

yeah, bearing it in mind during the build - will turn a lot of heads being so small + damn fast lol

Scouse Monkey
12-03-2006, 12:46
sharp protrusions is a big issue on SVA. and you will need wheelarches. There is a nice set of carbon fibre ones at work but they belong to someone bigger than me who is fitting them on his lotus 7.

Scouse Monkey
12-03-2006, 12:47
oh, was walking home in the snow at 2 this morning looking at wheels....pug206 GTI alloys - the multispoke might look cool and be strong enough (pug alloys are damn near bullet rpoof).

2Fast
12-03-2006, 12:50
plus the lights need to be set within certain perameters, the engine will probibly need covering (comes within protrusions) and all welding needs to be top notch.

AJ
12-03-2006, 12:54
Welding needs to be top notch.... :( ohh well james ;)

Scouse Monkey
12-03-2006, 12:55
the lights is easy to do. YOu will also need a windscreen unless you leave helmets on the seats :D

And you need a compliant bumper - at least on the front for pedestrian safety. Oh and one more thing....if you want to avoid a Q plate you need certain parts off a donor car..there is a points system with so many for engine, gearbox, steering etc etc but i assume you are just going for a Q.

James
12-03-2006, 19:06
one of the base joints:

2Fast
17-04-2006, 20:50
i presume you've checked the needle valves for blockages, the float heights, if the engine has been sat for a while the fuel in the carbs will have turned to varnish and will need cleaning out, the spark is strong at each cylinder, the compression in the cylinders, the timing.

not possible, because cylinders 1 and 4 fire off the same signal (ie: together ) - so if 4 is sparking, 1 will be too

James

Confused
18-04-2006, 10:27
They wouldn't be firing together. They may go up/down together, but they'll take turns in firing (firing order is probably something like 1-3-4-2)

I new it was funny but got the order wrong :blonde: , it's 1-2-4-3

in case you have forgotten the firing order for the Crossflow it is 1-2-4-3.

2Fast
18-04-2006, 10:46

Yeah, but 1 and 4 should fire out of sequence, i.e. 1 fires and pushes the piston down, when it comes back up, 4 will fire.

Confused
18-04-2006, 10:49
In that case I was wrong too (I was basing my guess on what you posted as the firing order) :)

how about a little extra power..

see the small turbo (http://videos.streetfire.net/video/wm/9AB8E11C-B2B7-4D34-A23B-22272D9A953D.htm) on this beastie ;)

not possible, because cylinders 1 and 4 fire off the same signal (ie: together ) - so if 4 is sparking, 1 will be too

James

They probably do spark at the same time but at opposite sides of the stroke.

When 1 is firing 4 will be exhausting and therefore the fact that the sparkplug is getting a charge will not make any difference.

My terminology is probably not quite right, but you should get the idea :lol:

2Fast

If the GSXR's are anything like their older brothers the GS, you will have two coils, the coils will have two HT leads at one end and two signal wires and a power at the other (and maybe an earth).

If you look at coil 1, the two signal wires take a pulse from the crank at the relevent time and power the HT leads independently, one the first stroke and the other on the third.

James
26-04-2006, 00:23
no, only two connectors for each coil, power and the earth switching input

I may have been quiet but I have not been idle!!

I've had to get a few new parts for the engine, which is now running fine.

Also got hold of the hubs+discs+brakes and today picked up some new wishbones, joints and U mount's all fitted with new poly bushes

Still to come is the steering rack + seats!

I needed the hubs + wishbones to be able to design the next level of chassis so I can continue building that now...




I couldn't help videoing the engine run - both with and without exhaust, give it a watch :)

drools!!! If only I had the money :(

James
07-07-2006, 15:48
Well my shiny new quickrack arrived today, and although it's the correct overall length and thread - the pivots are way too far apart for the low position it sits in, meaning it pivots out of arc and will give huge bump steer :(
I have a cunning plan to swap the hubs and flip them upside down, meaning the track rods will bolt down from the top instead of from underneath. This should move the pivot up the arc and into zero bump steer - so goes the plan anyway....

http://www.digital-car.co.uk/buggy/36.jpg

2Fast
07-07-2006, 15:51
Good luck with it, it'll be a bugger for one important component to ruin it now.

Scouse Monkey
07-07-2006, 15:59
can you not just raise the rack up?

will flipping them mess up the castor adn what about ackerman?

James
07-07-2006, 16:21
castor can be adjusted by shifting the top wishbone mounts fore and aft(still not made thankfully) to get the required 5.5 degrees

all three items - top, bottom and rack all need to angle to converge on an imaginary point called the instant centre - so you cannot just move the rack up and down - you must move the track rods too to achieve this correct angle

Final solution is a cut and weld on the non pivoting part of rack to shorten it - allthough it's commonly done on seven's - I wouldn't feel too safe doing it myself.

Scouse Monkey
07-07-2006, 16:40
hmm. is the hub pretty symmetrical with reference to the top and bottom mounts and the hub centre? I am jsut having toruble imagining the hub flipped and giving the same behaviour.

James
07-07-2006, 17:02
no, there's a slight angle which worries me, it might be a case of the lesser of two evil's though...

Scouse Monkey
07-07-2006, 17:04
no, there's a slight angle which worries me, it might be a case of the lesser of two evil's though...
thats what i thought. hmmm.

make it out of lego 1st.

James
07-07-2006, 19:14
Sorted it - mounting rod end top down puts the pivots all in perfect line - just have to have the taper remade to properly mount into hub....
disaster averted

http://www.digital-car.co.uk/wr4/48.jpg



It looks very odd here due to the different sized wheels - and the lack of a back making it look very tall - two different variations of the back are below it - which do you prefer?

iniially the 1st one. but then the second grew on me. but the 2nd still looks a bit ghey (only way i can describe it and i think you know what i mean). the 1st is stubby but stubby can be good and when you get the exhausts on there it will be better.
