I believe it can rev to 9k rpm. The give away to me is the sound of the engine, it sounds just like a 4200 engine. I bet it's been remapped and delimited.
The GTS can be changed to 8250 (morebeans FD remapped car did at least)

Hence the name of the band, but its not true

Probably more like 5 ml based on their diet, hydration and frequency of relief!

Unless you're thinking that Mancs are somehow 'bigger' in the bedroom dept
5ml would still be a big average.C

Yes - retrograde step in my view.

Agreed. Flat plane sounds like two 4 cylinder engines in stereo, this clearly sounds like a proper V8...

Supercharger would be the better, easier and cheaper route to gain more than the F430 with its thicker headgasket to achieve 4.3 capacity or a skim off the top of the piston
In reality I believe it's a slightly longer crank throw to a acheive the minuscule capacity in crease.
4244cc vs 4308cc
Over 8 cylinders that's a massive 8cc per cylinder extra capacity hence my thicker Headgasket remark and to give you an idea of how much 8cc is, 10cc is the capacity of the teat in the end of a condom
Exactly right (about the bore, no idea about the teat in a condom). Stroke and an F430 is 81mm, Coupe is 79.8mm
The head gasket or piston would change the compression but not capacity. Swept volume is the amount of air/fuel displaced by the movement of the pistons, so can only be altered by the bore or the stroke.
At risk of reopening another can of worms, the 4.7 has a bore of 94mm and a stroke of 84.5. So a 4.2 with a 4.7 crank would give 4494cc... Maserati 4.5 anyone?
As Mike says, go to their website http://www.sportwagenprofi.de/ . No engine swap.

It certainly lacks the secondary out of balance forces in a cross plane V8. But the sound....

Thought this would create some controversy It does seem to rev quite high...

If could just be a remap on the ecu raising the limiter.

He's short shifting it for a Ferrari V8 - they all go to 8800rpm. The engine does not sound like a single plane crank. Remember the singe plane changes the phasing of the firing strokes so each bank fires every 180 degrees - sounds very different.
The 4200 engine uses cast not forged internals (can't speak for a 430, but my F355 engine has titanium conrods as std). Cast internals cannot take RPM 8k is about the max for any cast conrod, and plenty fail at this speed. I've even snapped forged rods....

Intriguing, I read the Maserati spec for the F136 engine and they say it has a "refined forged steel" crank. No mention of con-rod materials though, can't imagine they would go for a forged crank and then use con-rods made of butter but stranger things have happened.

I bow to your knowledge but I have to disagree with you; after DMS removed my red-line ignition cut I have (accidently) taken my (4200) spyder round to the (turn) dimmer switch without exploding. I try not to do it but, as yet, it hasn't complained. True, the power drops off above 8500ish but, as yet, there hasn't been an exoensive bang. IMO, these engines are as tougher than a rhinos chuff. Why it hasn't gone BANG it a mystery to me and several of my driving buddies but long may it remain so!

If Benny hasn't broken his yet the thats good enough for me.
This pic from the workshop manual shows a wide irregular line on the crank webs, my understanding is that cast cranks have a well defined line on the webs where the mould is split... Rods appear to have H beam design with ARP style bolts.
