Default New Rothsport crank pulley/balancer.

Saw it today on IG. I was on the fence when upgrading to single row crank pulley because of the "no balancer" possible problems. Now, not so much... can't wait to buy it! Hoping it's not like $2,000 bucks



Thanks!

I'm a buyer if it has A/C pulley for a 964.

This is really for big build motors. Like Roth builds. 4l etc

Beautiful piece of kit. It appears that belt tension is achieved by adjusting the idler pulley eccentric, rather than by a spring-loaded arm.

Interesting. The 4.0L monster Gamroth built below, doesn't happen to have that on it. Maybe the client did not want that setup.

Looks like it's on this monster motor.
Plus, look at that carbon airbox!

From speedhunters
http://www.speedhunters.com/2017/10/...er-werks-400r/
Hanging behind the rear axle is a hand-built Rothsport Racing 4.0-litre flat-six. With a minimum output of 400bhp and 330lb-ft, and a MoTeC ECU imposed redline of 7,800rpm, it isn’t your ordinary Porsche motor.

Extensive research and dyno tuning found that this Eventuri intake coupled with a carbon GT3 plenum provided the best power output.

The fan, while identical in size to the one found in Turbo models, features twisted vanes as opposed to the Turbo’s straight vanes. It’s another completely custom piece that was researched and developed to the nth degree.
