So when you hit the redline, do our cars cut spark or fuel?

 

Both iirc, it is very abrupt and always scary to hear this happen on the dyno.

 

Well with a forced induction motor I thought that it would cut spark instead of fuel.

I'm thinking on running nitrous on the car so I'm concerned.

 

I know the redline/ rpm limiter in the XJ8 (all N/A 4.0s)
are 6800 and 7000 respectively,

What is the redline/ fuel cutoff in the XJR?

I know peak power is at 6150, I assume it
will rev past 6150.

(really hoping this post in an old thread gets noticed)
