impressive so far - even if fuel limited at 5800rpm.

Where is the 40degC IAT measured?

So good :good:
Interested to see the outcome re hardwiring the pump.
Lmk if you need diagrams.

Is the standard jetpump a consideration?
It can cause a restriction on the return, potentially stalling the pump.

Radium make an upgrade kit with different orifice jets.
Is your system returnless at the rails end?

Just before the throttle body.

The fuel rails have been modified so the fuel now enters in the middle and the return is on the end of each rail. The company doing the mapping have carried out the mod so will have to wait and see what happens. The prop is off the car and being sent out to get the middle bearing replaced.
Apparently at 5800rpm all the numbers are increasingly rapidly so who knows where it will end up but i don't think it will get close to 500bhp probably still around 450bhp but with a greater torque spread, just want the car back asap as I haven't driven her since February.

Not been here in a while.

So at the end of all the mapping we still have 440bhp at flywheel 360bhp at the hubs. Have started building the next engine but the lockdown slowed progress down so still waiting to get some additional maching done. To get the max from the new SC i need a larger crank pulley and get a 75mm pulley for the Rotrex.

Have spent some more time on the bodywork getting the front bumper sprayed up and a lip spoiler I had lying around modified to suit, fitted a C West rear wing and finally got the modified bonnet painted and put on.

I do have a wide arch kit to fit at some point maybe leave it until the winter.

Surely you must need a CorgiWerx 12kg or 20kg centre diff?
Picture for attention.

That's a mean-looking wagon. Great stuff.
