Was i mistaken or did it say he wanted to make it 800+HP ATW?

The combo of turbo + supercharger is not a new one.
In 1985/6 the Lancia Delta S4 Group B rally car had both a turbocharger and supercharger...it is said that one of these cars in tarmac spec was tested at the Estoril (Portugal) Formula 1 circuit in 1986 and set a lap time which would have put in on about the third row of the grid in the 1985 Portugese F1 Grand Prix.... now that's impressive!

Slightly different config on the delta tho (besides the obvious).

The Delta was Twin-Charged I believe, running the supercharger for low-end power and then allowing the turbo to take over once it had spooled up. Rob is a compound setup using the supercharger simply to spool up the turbos - otherwise I believe it wrote that they didnt spool up until after 7000rpm.

But its certainly not new - was used in airplanes back in 1940's or something prior to jet development.

Hats off to the dude tho. Love to know how many engines got destroyed under testing!

as geoff and a few boys noted on irc, the setup is pretty flawed when u look at it closely. it's still running MAF, and the twin intakes joining into one pipe is a bit of a worry. he wont make that power if he doesnt address those issues.

The supercharger doesn't run in a compound setup to help the turbo's spool, its running on its own, and looking at the setup, has an actuator to then bypass it when it hits a certain boost point, looking at the pipework setup and the boost actuator on the super charger anyway. so its running in the traditional twin charge setup of supercharger down low, and then the turbos come in when they start to work..

you will find the reason it kicks the turbos in earlier than 7000 rpm, is because of the extra exhaust gas hes making by running the supercharger to create boost in the lower rpm range, which will mean theres enough exhaust gas to drive the turbos earlier, i wouldn't expect them to be working until around 5000 rpm tho..

I stand corrected then

I'd love a ride in it regardless!
