NC power limits with stock engine and fuel system

Postby magenb » Thu Dec 18, 2014 9:47 am

Hi Guys,

Just looking to get a bit more power out of an 06 NC, but don't really want to go changing injectors/fuel pump etc. Any one know how much power you can safely put through the stock system?

How much I can get out of the stock system would lead me down that path, for instance, if I'm going to be topping out at around 150 wrhp then there's no point in going forced.

A set of headers with full exhaust and a tune will get u between 110-115rwkw. That's probably the limit without opening up the engine.

Forced you are looking at upto 170-180rwkw. But you'll need to upgrade fuel system for that

modest changes will add modest KW- if you got 10% more you would be doing well I would have thought.
