Resonator bung

[Niall]

How did you swap the resonator in seconds though jp? Surely it's a manifold off job?
And surely even back to back runs will cause heatsoak in parts of the engine which would easily account for a reduction in torque?

Well providing the engine was up to temp for both runs, it doesnt matter does it? Your not going to run the engine at standard temp with the resonator and then do your best to keep it at 40 degrees with the box back on!
