ProBoost is a company in Saarenkylä, Finland that makes turbo kits for motorcycles and snowmobiles. However they are also building a custom motorcycle. The custom chassis is built around the power plant, a 4.0 L BMW M60B40 V8 running twin-turbos. The 4.0 L V8 produces 282 hp and 295 lb-ft of torque from the factory so you can guess how much the twin-turbo version might produce.

“4.0 L BMW M60B40 V8 running one twin-turbos.”
Isn’t that a mistake? Because I havent heard about one twin-turbo.
Yes it was a mistake. Thanks for bringing it to my attention.
No problem. We all make mistakes, after all we are only human.
Well said, sir. 🙂
what size turbo´s? 16t?
All their motorcycle kits use a TD05H-16G. My guess is these would be the same.
