580bhp on a T4 a 2.0 bar is a physical impossibility, let alone 680......
With high compression (the Touring cars often ran figures starting with a 6!), my own car makes 543bhp at 2.2 bar and on 2.2 litres. Admittedly this is on pump fuel, and you could add an additional 30-35bhp with race fuel, but it is still way short of the figures being bandied about.

Its worth understanding that the porting of the rear housings would really harm turbo responce, but also improve engine VE through backpressure reduction, that is where they would gain, not through Compressor flow, through reduced pumping losses, but they arent gaining nearly 200bhp through it.

p.s Ha ha, Agar got into trouble
p.p.s In retrospect, thread of the week
#107
1991 , bathurst , the skylines clocked 299kmh down conrod , a record , at the time ( this was the last full fat gtr , all genuine 600hp for the top teams , 580 or so the lessers , before a 19psi restriction for 92 )
The sierras were definately in the mix with them , but nothing was recorded i believe , but few were
Courtesy of 'supertouring' @ tentenths , and his full technical artical of rouse's 500
440lbft @ 6000 570hp @ 7300 were the quoted figures
- To my eyes would bare fruit that , johnson may have meant 580 not 680 in that interview , slip of the tongue etc

Glen seton , also won rds of the atcc etc against johnson , had quoted his spec to be 580hp , @ 2.4 bar on 6.2 cr
to add further weight to the subject

And those rumours about nitrous, fuel stored in roll cage, well that's just bullshit. They never had such things and if you do some maths (for example looking at how much fuel you can store in a roll cage) you would see it makes no sense.
I have seen few times some Delta S4 with my own eyes and close enough to touch them, take pictures on the inside for example, and believe me they have NO fuel cell under the seats and these cars I saw were rally cars, not "stradale" (aka street version) converted. Why would they even need that ? The biggest engine at that time was the 5cylinders of the Audi Sport Quattro S1 and even Audi didn't need that to finish rallies.
Its a bit off topic, but I had to clear this up.

I think you are confusing LANCIA with TOYOTA ! Lancia has never been banned whatsoever. They were at the beginning of the group B era and continued through the group A era but they have never been banned.

And again they had no consumption problems. It was not nos either, be sure. I even heard stories that some teams may have used air conditioner compressor and cold pipes connected the the intercooler. Bullshit. You always hear wrong things to "make the legend", like the one who said Toivonen could have qualified 6th or 8th at the Estoril F1 GP in 1986. Again its bullshit, but there are things like this that are difficult to erase.

but there was use of nitrous in fire extinguishers in Delta as far as im aware and it is in literature and some of Duke`s media videos, (not S4)
honest im not telling porkies!

My T4 is a very modified touring car item and produces very good power....
1.0 bar is 392bhp (Area52)
1.8 bar is 498bhp (Area52)
2.1 bar was 562bhp (nobles)
Both rolling road pub figures but it makes good power

Turbo must be poorly - these should make 680bhp @ 2.0 bar .
I have to agree with Santa Claus, that it was likely a slip of the tongue, and he meant 580bhp (but still not at 2.0 bar ).
The power was enhanced by running toluene, allowing lots of ignition and big boost levels, so 580bhp is just about believable on these exotic fuel mixes. But I bet that would still be qualifying boost, and you'd turn it all down to 520-540 for the race to prevent risk of engine failure.... On the right gearing, that would still be good enough for 300km/h or 186mph with a long enough straight.

Mike my engine is on 97 ron fuel and on a rolling road.
Race fuel and perfect conditions in a dyno would see over 600bhp no doubt.
Plus race engines are normally built for that racing so on the limit....not 20,000 miles.

The mechanics were given special gloves to allow them to switch turbos quickly without it melting to their hands!
