Testing and tuning underway for this monster. The manifold is an equal length twin scroll tube style kit. Currently running a water cooled 67mm garret turbo. There is no words to describe the exhaust note of this s55. Many people hear it and think it’s a v10 lambo. Gone are the days of the horrible sounding s55. I am posting this to get a feeler on how many people would be interested in purchasing this kit. Of course this is just a teaser shot of the engine bay and I will have full pics of manifold design including logs, dyno numbers and price lists posted in about a month. It’s already making 580hp on stock boost levels 18-19 psi according to the I drive display.
