The key here is longevity. You can get 1100 hp out of a Supra engine. But for how long?

  • 400bhp/L would also be way above what would be nice to drive on the road. Huge turbo with high boost threshold etc, totally intollerant of low quality fuels and probably not even happy on the best pump fuel etc.. just not realistic. 200bhp/L no problem/ 300 boarderline 400 not likely.. If it was possible loads of supras would be 1200bhp+ and simply there arent.

Exactly. Plus at those sorts of horsepowers you are talking about new pistons, rods, heads, block strenghtening etc. If you want a high horsepower reliable engine get a Keith Black big block and stick a couple of T88 turbos on it. Just don't expect fuel economy.

In news: snipped-for-privacy@individual.net, Fraser Johnston wrote something quite bizarre, possibly in an effort to confuddle the world. It went like so;

I know someone with a Keith Black Hemi, it's 10.6 litres of loveliness.

As for bhp/l, I'd say for a road car 205 bhp/l is the very maximum for driveability.

It's the same argument, isn't it ?

The little gold thing is the reverse box. The sequential bit comes from still having the bike box.

Most bike engine cars or BECs as they are now called, unsurprisingly, don't bother with any form of reverse. I know at least four owners locally - none have reverse. All MK Indys - two blades, one R1 and a ZX12. They only weigh

450kg though, so it's hardly a hardship. I could be tempted down that route myself eventually, but the motor will have to be dirt cheap of course.

I get more than that from my micra haha. But it is already quite choosy over fuels. I agree tho, a very realistic target to aim for to maintain the good things of a standard car..

I used to get 264 bhp / l from the Cossie, and it could be a bit... tempramental in traffic.

As in, mimble mimble mimble BLAAAAAAAAARP bang bang bang bang stutter mimble mimble mimble.

Not what you need on the commute to work.

And which do you think will be quicker for everyday driving? Problem is with a 1000bhp Supra it'll be a real pig to drive on the roads due to the lag caused by the huge turbo required. Don't even think about letting the turbo spool up unless the road's bone dry. The Veyron's engine is built to give production car levels of reliability, Supra's can easily produce 1000bhp+ but it's life will be greatly reduced. I'd rather have 125bhp/L and huge amounts of torque at low revs and no turbo lag than have 400bhp/L with no power below 5000rpm then a sudden boost and you're looking for the next gear.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Douglas Payne saying something like:

Oops Ken, you've been sussed again.

I can imagine! I helped build a 550bhp Evo I, that was the most crazy thing I have thus far ever been in, and that was not really happy in traffic either.

But the expert engineers at Bugatti could have used 2 (or 4 on V8) turbos sequentially like the Supra did in stock form. Should give nice linear power build up and good bottom end that Supra is noted for as it boosted from 2K rpm. Tuners dump the twin setup for lots of reasons

1 they can't get big matched turbos with the right housings. 2 they don't understand how to size turbos to work sequentially in series instead and can't take the time / cover costs to test setups and learn. 3 cost (hardly a problem on a £1m car). 4 customers only demand outright power and not street drivablity

The Bugatti budget ran to 16 titanium con rods, I'm sure 6 or 8 (for

2x 1.8T) wouldn't have broke the bank and would be well up to the job. The money saved on an excess of pistons would have paid for decent forged and coated pistons well able to cope with the higher loading

Thats more than likely the only reason. Customers wont pay the cost of development in stuff like this. Sequential turbos are not that nice anyway.

It's a £1m car. What sounds better, I have a quad turbo W18, or I have a twin turbo V8.

Me thinks you're somewhat missing the point :-)

Twin Turbo V8, 'cause that's not BS.

As Stock as Saab intended it. Which is plenty for a 13 year old car. Any closer to 200bhp through the font wheels and traction control becomes desirable (but not essential). And having a gearbox that implodes about

200BHP(weakend version of a 27 year old design meant to handle 120BHP) doesn't help much.

Good enough for 0-60 pretty damned quick and enough midrange poke to stop a 911 Carrera S closing when I had no gap to pull into and he wasn't playing nice.

You type with your feet and and wear leather for pleasure don't you.

can't you please name some of these spammed up elderly saloons Please. As you know so much, exact models please. You will be marked on accuracy before being shown the door.
