AGM WLR V12 - Arrival
StuartBJ - 9/8/10 at 10:23 AM

Hi Ladies and Gents,

Well I`m a very happy bunny this morning after Alan from AGM came and dropped off my custom chassis, engine, gearbox, diff, shock/spring....etc etc yesterday.

The chassis is one of the 500bhp types which has been widened to fit in the monster V12 from a merc SL600.

Now the work begins.........

Any chance you could retake those pictures, they are blurred AND 'kin enormous?


StuartBJ - 9/8/10 at 10:50 AM

Sorry, I don`t know how to resize the pics! They are big files!!....taken from an iphone....anyone know how to make these smaller?

Thanks

scutter - 9/8/10 at 11:17 AM

That looks fantastic, but i'd have to say that chassis doesn't stand a chance.

ATB Dan.


iank - 9/8/10 at 11:19 AM

Blimey, that's a big one

What's the white powder over the front, looks suspiciously like powder extinguisher residue.


StuartBJ - 9/8/10 at 11:24 AM

The chassis should be man enough for the job (fingers crossed)...its rated for 500bhp.

Well the white powder wasnt there before ....hmmm


carpmart - 9/8/10 at 11:27 AM

that's a bloody mahooosivveee engine there!


StuartBJ - 9/8/10 at 11:39 AM

and the really surprising thing is that its not amazingly heavy either.....Ali/Mg engine at a guess..... oh and here is the T5 gearbox adapted to suit the SL bell housing.

Isn't this engine a bit...euh....overkill ?


mrwibble - 9/8/10 at 11:45 AM

where do the wings and the propella go?

good luck you crazy fool


StuartBJ - 9/8/10 at 11:47 AM

How so?......

Size? .... not really when you remember its a lemans styled kit car and its NOT a seven.

Power?....plenty of kit cars have big power whether thats a mutant cossie lump or Whopping V8 prducing a million HP.

and when you get offered 500bhp for £450......who am I to argue....

That's a big motor...!

Out of interest...who rates the chasis at 500bhp (any torsional or stress testing results)?

...and what mods have been made over the standard (MK Indy based) chasis?

AGM had the original chassis and wishbones stress tested on a jig and then a report was produced (which makes a good read). The conclusion and suggestions were then developed in to the chassis you see in the pictures and the new chassis was re tested.

If you look at the the AGM pics it shows a few good pictures of the chassis for you to compare but basically there is extra strengthening and cross members etc + recomended panelling and widening to increase rigidity.

I Like this!


Irony - 9/8/10 at 12:07 PM

How will you see over the engine when driving it? Or is it not in its final position?

Nope, its on the deck atm and not nailed down, so no problem there. Amazingly it fits under the standard bodywork........ I was shocked!

with that motor under the bonnet I bet the sump is so low that the front wheels don't actually touch the ground

must admit i do like the shape of the WLR, looks like it will be a bit of a beastl
WLR chassis with a LS-1 V8 fitted


02GF74 - 9/8/10 at 12:47 PM

blinkin' marvellous. good to see something different being built.

do you know what the weight of the enigne is?

and how will you be fuelling it, using megasquirt/after market ecu ?


hughpinder - 9/8/10 at 01:07 PM

Wow - Impressive ... Can we have a sweepstake on how long the rear tyres last?

About 100m


StuartBJ - 9/8/10 at 01:15 PM

Well the hoist had no problem lifting it to full height on the 250Kg setting. Hard to define the weight but must be about 200Kg.

I have a Megasquirt unit for the engine MS extra with 2x v6 coil packs (ford).

The fueling is via the original merc pump (complete with swirl pot) but I havn`t run any lines yet and I`m waiting for a follow up pallet of parts to turn up.... including the fuel tank.

I have ditched the original TB`s which were stepper motors (drive by wire) for some shiny red ali 80mm cable operated ones.

I will try and detail the install at each step with pics. I`m sure lots of people will be intrested in the Megasquirt.


scootz - 9/8/10 at 01:17 PM

Sounds like fun... looking forward to it!

From a tanker!

Nice job!


StuartBJ - 9/8/10 at 01:20 PM

Hmm..... fair comment

But another good story....

I have a set of NEW Merc ML alloys 9.5 inches wide (Rear) for £160 (via ebay) from a specialist alloy shop in essex that couldn`t sell them

The mecredes alloys fit Granada hubs (5x112)......

What size tyres do you think are best for these rims 18" x 9.5" ....255? 245? 265? 275?

That's very encouraging to hear - often these things are claimed with little in the way of real evidence.

Looking forward to your progress, should be a beast and half!

Probably a little bit north of 200kg but the LSx engines are around that with the ancilliaries. However using the T5 will save a useful amount of weight compared say the T56 usually fitted to the LSx engines. I know because I've lifted one and it's big and heavy.

I also ditched the DBW (on a LS1 not a V12) and went for a cable throttle. They are good for emmisions plus economy at light throttle and can be integrated into traction control but often loose the pure response of a cable throttle.

I suspect it was built to fit but it does have the added benefit of both as Alan used an LS1 in the demo car and that can`t be exactly.....froogle lol


franky - 9/8/10 at 03:04 PM

Soa genuine 180 mph!? Thought real men turbo those engines

on a serious note, would it not be worth running a dta type ecu?

I don`t really know enough about them to be honest.... I counted my lucky stars when I found someone that could supply an ECU that would be wasted spark on a 12 pot. If it works I will be happy

As an LM prototype car, i would surmise that it was sized for 10 laps (or so) of Le mans!


kb58 - 9/8/10 at 03:55 PM

A chassis isn't "designed" for horsepower... the chassis only knows about torque, more specifically, the maximum amount transferable to the ground, probably be a lot less than what the engine can develop. So, it really comes down to what tires the designer worked off of. Hopefully he designed it for worst-case, racing slicks, and not all-season tires!

[Edited on 8/9/10 by kb58]


But if you said to Joe Public that the chassis was designed for 600lb/ft of torque, they wouldnt understand.

Horsepower in this case is a reference method methinks.


StuartBJ - 11/8/10 at 11:00 AM

Yes, I agree.

We all know that its actually torque that is the important factor but we all still "speak" in terms of BHP (or KW) when it really should be lb`s.

Agreed, but since we aren't Joe Public here, I'm curious what torque the designer built the chassis for. If he says "500 hp", I'd be concerned!


StuartBJ - 11/8/10 at 02:36 PM

You`ve hit the nail on the head... It is aimed at Joe public looking at starting a new kit aswell as the more "experienced" enthusiast... Even today I saw "a which chassis" question posted.

I agree that its not technically right..... but it gets the point across to the masses.

I wouldn't go by what the hoist managed. I used mine to lift my lathe on the 250Kg setting, only to find out later that the lathe was actually around 900Kg


James - 13/8/10 at 03:11 PM

I'm a little concerned by the absence of any tubes to stop the engine bay lozenging. They are missing on the MK too but it's very hard to get this vital chassis strength back.

I know it's hard to fit them in the engine bay with a big engine so the alternative is a 'Y' brace.

This is all outlined in Cymtrics' mods and documentation which you'd do well to investigate.

Cheers,
James

The chassis only sees the reaction force from the tyres. Torque at the flywheel means just as little as bhp when it comes to chassis design once you factor in diff's and tyre diameters.

Which is why I wrote:

I don't agree that it's all about tires, though. The chassis does see engine-reaction torque along its length, which does indeed twist it. Yes, it'll be less than the maximum torque that the engine produces, due to the tires "bleeding off" torque above some amount.

Ironically, mid-engine cars have far less of a problem in this regard, and transverse mid-engine cars have no chassis twist at all!

[Edited on 8/14/10 by kb58]


interestedparty - 14/8/10 at 06:02 AM

Always worth remembering that unlike power, torque is multiplied by gearboxes and CWPs.


StuartBJ - 17/8/10 at 10:49 AM

Well most of my first weekend involved some lengthy chats to passers by asking "What the **** is that ?"....but that asside I was fairly happy with progress this week. I installed the diff and driveshafts, the diff required some light trimming to fit perfectly but nothing a well aimed hacksaw couldn`t cope with. I also offered up the gearbox, steering wheel and enjoyed my "right of passage" from the soon to be cockpit.... "brum brum". The cone filters may cause some future concerns but I`m sure these can be accomodated via some means. The alternator will require relocating to allow the steering column to be positioned correctly but this sin`t an unexpected problem.

I`m just waiting on the bolt pack from AGM and the car will be in rolling chassis form (fingers crossed that will be this weekend).

You will see from the pictures that my propshaft will be alittle on the small side. Ha Ha......its not the size that counts

And yes.....i gave it a bit of a wipe too

kb58 - 17/8/10 at 01:24 PM

Have you sat in the car to see if the shifter location works for you? In my cars, the shifter ends up being nearly in line with the steering wheel for best fit. In the picture above it looks like the shifter's about two feet behind it. Just sayin...


StuartBJ - 17/8/10 at 01:48 PM

Yes I have and it "isn`t bad" but could be better with a gear stick mod...... to be brutally honest. Not a show stopper though.


StuartBJ - 23/8/10 at 12:22 PM

Hi Guys,

Well weekend #2 - The plan for this weekend was quite a relaxed one, get her on all four wheels.

Well, It was easy enough to attach all wishbones to their respective pickups but my coilover bolts were still in the post, but I did have enough odds to build one corner.....as you will see.

Then my next issue, my mushrooms didn`t fit well (becuase I`ve used Granada hubs). So... I have asked Talon Motorsport to turn me a couple of new ones to suit...which means a trip to the garage on Tuesday night to measure the Hubs up.

So hopefully this time next week I will have moved past the suspension on to another of my many jobs.

But

How on earth are you going to fit the steering column?

Unless you are planning on a rudder


StuartBJ - 24/8/10 at 11:01 PM

Good question......

The alternator is going to be relocated to the opposite side

StuartBJ - 13/10/10 at 08:19 PM

Well after two holidays (USA and France)..... I thought an update is well overdue......on a side note France may be one of the style capitals of the world but thats no excuse to spray a Rolls Royce Phantom in matt black.....

Anyway......the suspension is completely done, although I will have to re visit the IRS and change out the threaded bar in favour of some very large bolts (see other posts).

The rear brakes are on and ready for lines (in progress), I`ve opted for the vented cosowrth rear discs, pads and calipers (new) ...... ohh note to be mentioned here, I have three pairs of granada hubs and yet two pairs didn`t fit and had me scratching my head for hours.... the hub carriers from the cosworth granada and standard granada are about 10-15mm different in mounting points due to the brake disc width difference, so I`m now left with 2 sets of standard granada hubs..... (any takers???).

The engine is fully in..... and mounting it was .....hmmmm well ...... easier than I would have thought..... as far as aligning and lifting a few hundred kilos gets..... but it had been a job that I wasn`t looking forward to so a lot of satifaction now it is complete.

ohhh and I have fitted the steering rack with some solid style alloy mounts from eBay and the top part of the steering column are now in place.

The Front 8 pot caliper brackets are now slightly overdue .... but hey they are being machined up by a mate for the price of some beer so I can`t really complain.

The oil cooler, handbrake cable has been offered up ready for fitting this week.

Friday should see a delivery from Alan at AGM with the fuel tank and nose cone/radiator bracketry.

I've just ordered the tyres and wheel spacers for the car, when these and the fuel tank etc are on (and I have had a good garage tidy upsession)....I will post some more pics.

Still lots to do..... but looking forward to seeing the radiator installed and rolling rubber.

coyoteboy - 13/10/10 at 11:45 PM

I'll be fascinated to see how well this handles. I love the insanity of it, but I feel like it's risking being a boat anchor with no rear traction due to the frontal weight? Quite excited to see!


StuartBJ - 14/10/10 at 12:38 AM

I know what you are getting at.... its not a bike engined car and thats for sure (well mine isnt and I`m sure Alan from AGM will thank me for pointing out that it can be easily fitted with one) but my WLR is an ali lump and should weigh similar to a cast iron V8, so left to its own devises it should handle similar to something like an Ultima, but really its all down to the setup.

I will fine tune as much as possible, camber, toe, aero and pressure all round until I`m happy..... but you can`t go far wrong with DBL wishbones all round.

Where the WLR should shine is the swing axel lengths as they are near parallel, similar to single seaters, so im guessing im in for a sharp (turn in) but spine shattering ride...... but when I spent an hour or so in one on the motorway it seemed fine....so perhaps its a case of suck it and see with respect to the damper settings.

When all is said and done its a car for a LeMans style track (Long) and power comes in handy on the straights, in comparison it will be intresting to see how it handles on the B roads and short twisty circuits.
