Rather, how high is high boost, when on “low” it gets 600hp

That’s my kind of low boost

Could someone explain to me how this works?
Also:
By day, you’re running the Paris-Dakar. By night, you’re cruising around Mayfair.

Sorcery.
But in all seriousness, I think it’s something like this:
While most 16V cars are setup like this.
They probably tested it, saw some performance increase, and because it was group B, they simply didn’t care about the complex exhaust and intake header design that were required to run that kind of setup.

Correct! using cross valves setup you dont’have a cold and a hot side of the engine, so there’s a more omogeneous termic expansion of head and engine block, this allow higher boost pressure.
Cross Valves also increase turbolence inside the chamber for a better volumetric efficency, and having two exhaust manifold allow to use a turbo feeded by all the cylinder for each side.

What have you done… Now I want this in Automation 
Ah, a little less complicated than I thought. I got the impression there were weird valve angles and timings. Still interesting though
Yes, because the RB-X, the GT500, and the N1 are completely unrelated to the RB26. They’re certainly not RB26s modified for the demands of racing. By modified I mean cast with improved cooling, lubrication, re-enforcement, including forged pistons, and having parts balanced to a higher standard, ect.
Calling the RB-X GT2 a 2.8L RB is apparently a sin.
I sincerely hope this asinine argument of ours is a terminology issue or something to that effect… but either way; I’m done with it.

That’s very interesting; I didn’t know of that Lancia engine.

Wow. The stance of some of those cars…top notch!
A legend of 50s and 60s GT racing, and apparently also a decent rally car too…

Me competing in a rally cross, some of the racing club members thought it would be funny to let us race our trucks not realizing our suspensions could eat the bumps for breakfast. Came in the middle of the pack despite having only rear wheel drive and half of the power.

Indeed… Mercedes always made quite the lookers back then.
@Zabhawkin Nice… that must have been fun. Is that Frontier a KA or VG?

So I found something odd. A rally Delica.
Now for my obligatory Nissan/Datsun post, I have a Sunny.

The short-lived Group B era may have given us the wildest - and most dangerous rally cars ever, but it was the Group A era that I remember most fondly; not only did the cars resemble their roadgoing counterparts more closely than they do now, but it also gave us icons such as these:
Remember the Subaru Impreza WRX STI, Toyota Celica GT-Four, Mitsubishi Lancer Evolution, Lancia Delta HF Integrale and Ford Escort RS Cosworth? They were all proper homologation specials created to give their manufacturers a means of competing in the WRC. Sadly there is no chance that anyone will make another homologation special, because there is no longer any need to do so.
