Impressive stuff Nigel. Do I remember correctly that you were going for some boost control trickery too ? Did that come about in the end? Nice numbers

Yes I did fit 2 stage boost control and it works but in the end didn't leave it installed it as I have the adjustable traction control for in the wet scenario. The roller cam drives fine below 2k.

Good work

Excellent work Nigel!

My 5.5 seemed mental enough given its head. Yours must be outrageous!

Good move fitting traction control.

Very Nice

Wow..may I ask what compression ratio and max boost you are running?

[hoofa]

The engine compression ratio was built for forced induction so from memory around 8 to 1, boost pressure will be somewhere around 1bar

Any chance we will see you at a drag strip or maybe Elvington stretching its legs Nigel?
Be interesting to see if it tops 130 mph terminal in the quarter.

This is impressive!
You are going to twist the chassis every time you put some gas

[Zener]

Well our very own Derek as been regularly twisting them for years with similar HP and the car is still in one piece a NOS shot is far more aggressive than regular forced induction levels

[DangerousDerek]

Aah those were the days.
I now have a welded in roll cage which stiffens it all up.
