What’s the cheapest way to build a car with 1000bhp per ton?
Discussion
How would you do it? I’m thinking more something to take to the track rather than drag racing, but something you could also use with street tyres on the road......not a daily driver by any means.....but I would want to arrive and drive at track days rather than trailer it....at least at fairly local places. Also I’d prefer 4 wheels putting power down I think with that kind of power on legal tyres on a road.
So what’s the cheapest way anyone can think to do this? With an end result that’s drivable?
I’m just about to embark on this project myself with a friend. The car is bought, the AWD drivetrain is bought, the engine is bought, and we really haven’t spent very much money at all yet. We will be doing any fabrication ourselves (myself and a friend). We will need to get our prop shortened, and probably some custom drive shafts made up, but pretty much everything else we intend to do ourselves.
So I’m just wondering how everyone else would approach this on a very limited budget? The idea being to get it up and running and make sure the drivetrain works before adding more power. But a very basic setup should be 400bhp per ton, and with a bit of boost 1000/ton should be very straightforward.....and possibly even on a stock block engine.

Would anything be drivable at that power to weight ratio?
If you're doing it yourself the likelihood is you're going to wind up with something very light. Everyone I've come across with things approaching that, like a Westfield with an AJP engine, made the owners cry and swear never to drive it again.

Project E55 ASL might be a good watch for you. Not 4wd, however the guy previously added twin turbos to an E55, and is now building a 900kg car to house a similar power package so I'd expect around 800bhp/tonne, and it's a track car.
ASL stands for "Actually Sports Lightweight", in reference to Merc SLs being lardy.

Rip the motors and battery out of a crashed Tesla, chop the battery down to 1/4 the size, stick in something like a second hand sports special chassis (ie full body 2 seat space frame chassis).
It'll only go 120mph, but it's going to get their pretty dam quickly (consider the std Tesla P100D manages 0-60 in around 2.3 seconds and that weighs 2.2 tonnes...)

There isn't many time attack cars running 1000bhp/ton let alone track cars. I run a turbo charged Mev Exocet running 250bhp and 450bhp/ton and on track not much apart from radicals and high powered 4wd cars keep up. The only thing I know running 1000bhp/ton is a supercharged atom running wings and slicks but its a track only car.
I would ditch the 4wd system get a kit car get it too 500kg and fit a engine that can take 500bhp but without serious money and set up it won't be enjoyable or get a prototype car but defeats the point of a road car.

Instead of going really lightweight which may prove very difficult, how about aiming for 1500kg with 1500hp, like a lightweight heavily modified Nissan GTR / Toyota Supra Mk4? Having some weight might make it more planted when using the power, aiding traction a little.
Can't imagine this is going to be done sub £100k though... I'm sure a 1000hp Mk4 Supra on Carwow recently was about £70k of mods.

Then you got a really heavy lumbering car on track that can only go quick in a straight line it will also destroy tyres and brakes for fun most gtr I've seen on track don't look fun or indeed quick. In reality the 1000bhp/Ton aim on a road/track car is not feseable or likely especially on a budget or that fun. Can't imagine this is going to be done sub £100k though...

Something light. It's easier to get 500bhp in a 500kg car than 1000bhp in a one tonne car. This thread prompted me to look at the Atom V8s. Still not 1000 bhp/tonne but look at the price - https://www.arielmotor.co.uk/used/used/#content3
As i said up there^^ it'll be relatively easy to do for short periods with a Tesla based powertrain. P100D ludicrous mode is limited to 605 bhp by battery durab limits, so if you sack those off, then you've got at least the motor rated power of 762 bhp (combined Front + Rear), so you need a vehicle that weighs less than 750 kg,which ought not to be too difficult with a lightweight space frame and the smallest battery you dare fit. Likely to be far more reliable, and way quicker round a circuit than any highly boosted ICE powertrain (but top speed and duration limited)
