Veyron beating mini?

[Squig]

Just got off the phone to the ex' (traffic officer for the Norfolk Police) and she has confirmed that twin engined cars are not road legal.

Not for any construction and use regulation, road traffic act, highway code, IVA, SVA or any law for that matter.

Ready for this......






....you'd better sit down......






....since the DVLA "upgraded" their computers in 1994 the V5 certificate can not accept two engine numbers.




The quango's strike again.

out of interest can you find out if they can use non alphanumeric characters and the maximum length of any given engine number... following train of thought could they accept an engine number followed by a slash then the second number?

Yes mate I was been sarky it'd be amazing to achieve that sort of performance

I'd deffo be looking at the GT4 as the base car though. With the potential power levels we're talking here I don't think weight loss would be so important, but of course every little helps

123456-123457 Could work I guess.

We were discussing this in the pub last night and my friend who's a bit of a genius (prat) decided to do a g-force calculation based on the Calibra fully stripped out and fitted with two 600bhp 400 ft/lbs of torque weighing aproximately 1500Kg. As most of the weight would be over the driven wheels the grip would be incredible and depending on how good the tyres are the acceleration forces would be more than 3.0G!


All alcohol effected estimates but sound-ish.

I like the sound of that! 3G's pulling your face off

My theory for cheapest twin engined effort, laugh if you wish, and you will wish to, but it would be cheap... Granada Cosworth hatch, original engine still drives rear wheels, second engine in boot drives front wheels using 4wd transfer box, and front diff from 4wd granada, and one big drive shaft... you would have to get rid of a 'little weight' but would be slippery enough through the air, and you could build it with your average credit card limit...

[Squig]

Seems thou that the, assumed, twin prop arrangement adds extra weight and power loss... plus the modifications needed to widen the transmission tunnel to accommodate. Or have I missed a trick here?

If I'm wrong please slap me back into my place as a newbie... but the twin "FWD" setup strikes me as simpler and less messing.

[TeamTotalWankel]

Squig, don't be so diplomatic. Just say it's a daft idea!!

[McVities]

regarding twin-engines legality......what would happen if they both had the same number?

[Squig]

Squig, don't be so diplomatic. Just say it's a daft idea!!

Okay...



It's a daft idea!

[TeamTotalWankel]

regarding twin-engines legality......what would happen if they both had the same number?

Then, they really would be twin engines

[mjslonergan]

Okay...



It's a daft idea!

Daft but cheap, you wouldn't have to modify tunnel, just have the thrilling whirr of a cheaply encased driveshaft passing through where the passenger would normally sit... I love a bodge...

The Ariel Atom that makes Jeremy Clarkson look in his 40's until he hurts is back only makes 2.2 G. For a 200mph attempt though both gear boxes would run out of ratio. So a reworked longer legged pair of diff's would be needed.

[Squig]

I know that using the vaux boxes (F28 6 speed), not that they could cope with the torque as they are rated to 280lb/ft, using F18 wide ratio final drive gubbins it takes the top end to a smidge over 200mph... however I'm not sure about the Saab boxes. In theory the same principle would apply, but no idea which boxes have the required ratio'd parts.

weird, double post after edit. see below

Hi guys, weighing in on this one at Squig's request. The FM57001 is good for +/- 170 at 6000rpm however the b234r with a .264/10 cam can do 7500rpm without too much bother. Giving a potential to gear for 212 on 16" wheels. The problem being, as you put much more than standard power through the thing, they tend to find themselves turning to shrapnel.

As a good Saabist friend once noted - much above 350bhp the gearboxes are pretty much consumables or service items.

However all is not lost, Maptun got together with Quaife and now there are 6 speed setups, case braces and choose your gearset options. On the thought of the 9999 challenge, you could build a 9000 that will do >200 with one engine. Though I am told a ratchet strap is required to keep the bonnet on at over 165.
For this you will need
1 B234 engine (any 9000 2.3 will do) buy the whole car, it will be cheaper.
1 Holset HX40 from ebay
1 Holset rebuild kit
4 800cc injectors
1 tubular manifold
1 set of cams
1 truck intercooler
1 spare oil cooler from another 9000/900/9-3/9-5/classic 900/99/gm thing
a selection of hoses from pirtek
a selection of hoses from airsupplies
a windows 98 pc
a cable for flashing dvd players from a guy on ebay in germany
a universal 15v 1A power supply
8 brass pins and a steady hand with the soldering iron
a mug of really hot tea
a packet of chocolate hobnobs
some 4" mild steel tube

1 month to wait for the gearbox to come in from the trolls in Sweden, unless you are impatient, then some tin snips and a roll of gaffer tape and some second hand bling wheels with phat tyres innit... (say some 22-24" with some reasonably tall rubber on)

sorted.

ps the gearboxes on Saabs really are made out of primula/philidelphia. Don't make me post pictures.
