Twin scroll manifold – dyno results…

Another part we changed this year was the exhaust manifold.
The car was previously running an HKS twin scroll manifold so we decided to prove what Garage Whifbitz’s new twin scroll version can do and you can see from the dyno sheets below its pretty conclusive. Remember all we changed here was the manifold and wastegate.

The difference is quite amazing, 150lb/ft extra torque at 4500rpm and around 500rpm quicker spool up….
