Arrow Beastly 550hp Z4 by Manhart

Manhart has taken this Z4 and shoehorned the M5's V10 engine into it, something which seem to be all the rage lately, like this E91 3-series conversion.

Powered by its BMW V10 engine, the roadster is capable of 0-60 in just 3.9 seconds. Not only is its new heart from the E60 M5, but its 6 speed manual transmission and rear differential have each also been swapped out in favor of the one from the E60 M5. To help the car cope with all that power in the handling department, Bilstein PSS10 coilovers have been fitted, as well as a beautiful set of 19" black BBS CH wheels.

Quote:
PRESS RELEASE Manhart Racing – BMW Z4 V10

HEART TRANSPLANT – 550 HP in Z4

The M version of the BMW Z4 is famously known by nature for being anything but underpowered, since the chassis of the sports convertible already has a heck of a lot of work with the 343 HP and the forward thrust in the lower gears could last forever.

As is generally known however, the sport oriented motorist can never have enough power at his command. Sufficient cause for Günther Manhart, who by now has over 25 years experience in rebuilding BMW engines – a first for Europe – to transplant a brand new, much stronger heart into the Z4. The transplantation of the ten cylinder engine from the current M5 generation into the narrow engine bay of the roadster was anything but a walk in the park and it earned the Manhart Racing engineers quite a few grey hairs. Nevertheless: everything fitted in the end and now the fire of a 5.0 litre V10 engine with an impressive output of 550 HP blazes above the front axle of the Z4. A catalytic converter, a modified DME electronic control unit and the removal of the factory-set V-Max restriction up to 250 km/h are part of the rebuild. Consistent to the M5 V10 engine Manhart Racing has treated the Z4 to an original M5 E60 6 gear manual transmission which includes a Fichtel & Sachs clutch and a M5 E60 differential. An AC Schnitzer stainless steel exhaust system with four muffler tips which was fitted with HJS racing catalytic converters caters for a perfect V10 sound at the rear.

The Manhart Z4 M V10 goes like hell and thanks to the perfectly tuned Bilstein B16 PSS10 coilovers, the virtually unrestrained power of 550 HP can be brought under control to the tarmac. Black BBS Challenge wheels rotate in the wheel arches of the Manhart Z4 M V10 with 8.5Jx19 ET35 235/35ZR19 front tyres and 10Jx19 ET20 285/30ZR19 back tyres.

Conclusion: 550 HP ten cylinders, an acceleration from 0 to 100 km/h in 3.9 seconds, kerb weight 1450kg, 2.6kg per HP… who could guess that these impressive figures belong to a Z4? Hardly anyone, however Manhart Racing turns dreams into reality and does this with 25 years experience.

That fits entirely too well into the engine bay. Very cool.

I wonder what the new weight split is now with that much larger engine.

...not sure why they went with PSS10's when there are certainly better suspension offerings out there. But, then again, it ain't a bad choice...

Can't vouch for the Z4R, but I can assure you that with double the structural rigidity the Z4MC already is. I've been considering my current ride as a pet project in the future for an S65 engine, but and S85 would be crazy. I want to keep the car civilized, both powerful anf balanced.

That's my question, too. The car has a near perfect 50/50 and it STILL loves to rotate. With that much more power... oy... it might be a handful to drive fast on a track... (EDIT: to drive fast without looking like a stunt driver and getting yourself booted from CCA DE's for a year, LOL)

But that said, this couldn't be more accurate...
