Probably suffered a rod bearing failure before it even finished .

That's why no update

Scharbag · 07-16-2023, 04:28 PM

It's alive! Sounds awesome!

jp1984 · 01-18-2024, 03:04 PM

Finally!

Did I see 506BHP at 7500 rpm? Thats insane. I think I remember you (or someone) saying 9000 rpm may be achievable. what HP do you think you will be making there?

Also, is this a 4.0 or has it been stroked at all?

Yes, that's 506 @ 7500 on 93 octane (98 RON).

She made 527 @ 8100 on 93.

That's it for this dyno session. The next session won't be for a few more months.

It's either 4.4L or 4.5L. Nobody seems to remember. Haha. I think it's 4.5L.

Assimilator1 · 01-20-2024, 07:36 PM

Lol

Ditto what jp1984 said!
Wow that's quite some power from a ~4.5 ltr NA!

Especially when you consider that the M3 GTS's 4.4 ltr does 444 hp!

Was the power still climbing at 8100 RPM? Or was that it's peak?

Still climbing at 8100 with about a 10-degree slope.

Assimilator1 · 01-21-2024, 10:10 AM

Wow! Can't wait to see what it goes up to!

bmwfst1 · 01-22-2024, 08:55 AM

sounds amazing

serranot · 01-23-2024, 08:01 AM

This is spectacular.

M3SQRD · 01-23-2024, 08:48 AM

Damn!

m3s65b4.x · 01-29-2024, 02:06 PM

If dyno stend goes to separate bank 1 and 2 exhaust and reveal high power output plus amazing sound does it ever need x-pipe, front x/double x, rear x etc.

The firing order of a flat plane V8 does not need X-pipe because of it's scavenging characteristics. Powerwise at least.

bigjae1976 · 02-12-2024, 03:48 AM

Possibly close to 600hp at 9k rpm?
