Alfa Romeo 33 Stradale. It has a race-derived 2 litre V8 that sounds ridiculous. These days it wouldn’t stand a chance in the bhp/£ table.
It’s an 875bhp hybrid with a 599bhp normally aspirated 4.6L V8 but ok, fair enough.
991.1 GTS has 424bhp.

I don’t think the S54 would make the first 100, let alone the 1st 1000
The Atom V8 had the same 500hp 3.0l V8 and is road legalGuidoK wrote: ↑Sun Dec 29, 2019 4:36 pm The normal ferrari 458 is still missing from your list:
Ferrari 458 562 4,5 124,89 bhp/l
And from the 991.1 GTS there's a Rennsport Reunion Edition that has 430bhp so 113,16bhp/l (little difference)
And the mclaren F1 has a 6,1L engine so 618/6,1=101,31bhp/l
It might also be interesting to look at Radical cars.
There's an RXC (in street legal form) with a 2,7L V8 producing 430bhp (159,26bhp/l) and a 3.0 V8 producing 480bhp (160bhp/l) according to wikipedia.
They tune that engine to 550bhp@3,2L (171,88bhp/L) but I don't know if those are/ever been fitted to street legal cars (pretty sick though as that engine only weighs 88kg)
Have a look for the Judd E30 M3, awesome
It's cool but definitely a car engine! The RXC and Hartley V8s still use the heads from the Hayabusa (or very similar). I just love the whole garden shed hobbyist vibe with them.
Yes I've seen the E36 too, didn't realise the guy had died thoughMrPT wrote: ↑Mon Dec 30, 2019 7:01 pmIt's cool but definitely a car engine! The RXC and Hartley V8s still use the heads from the Hayabusa (or very similar). I just love the whole garden shed hobbyist vibe with them.
The Judd BMWs always reminds me of Georg Plasa now. Very sad.
EDIT - RedUn, did you mean the Judd E36 hillclimber? That was the car Plasa died in. Agree it's an incredible sounding thing.
And another here, I could listen to that all day.....!!
Torque is more useful on the road than bhp, bmw didn’t do a bad job with the e89 35is at 500nm as opposed to the e85 M at 355nm. Obviously larger turbos would increase the bhp output due to higher flowwspohn wrote: ↑Thu Jan 02, 2020 5:40 pm Nothing wrong with turbos per se.
My 2.0 (non-BMW) street car gets 188 bhp/l. To be equivalent, the new Z4M would have to put out 560 bhp. Sady, it makes do with a modest 382 bhp. They must have left a lot of potential power on the table when they decided to leave it at that. The previous generation (E89) barely matched E85 power levels using mild turbo.
I keep wondering what a current Z4 fitted with the top spec S55 engine (493 bhp) would be like. I expect that some well heeled owner will find out sooner or later, when they locate a wrecked M4 with usable engine - anyone know if it has been done yet?
True - and that 500 nm is just a bit less than I get from my daily driver GM 2.0 .
The Z4 M40i is faster (albeit marginally) than the detuned S55 equipped M2 Competition on the Nurburgring. Not to mention it has a ZF automatic gearbox as opposed to a DCT.wspohn wrote: ↑Thu Jan 02, 2020 5:40 pm Nothing wrong with turbos per se.
