Re: Cooling pipe work layout

Thats great, thank you.
Is there any reason i cant leave the hose on the bottom of the header tank connected to the heater return on the pump as the inlet is right next to the rad bottom hose inlet?
Im guessing it will perform the same function.

Re: Cooling pipe work layout

Stationary when the fan cuts in it has a job bringing the temp down and from memory won’t stop until your on the move again. It’s piped as below but I’m not sure this is correct, I ...

Replacing a tired 3.5

I’m helping a mate replace a tired 1973 P6 bottom end in his Westfield kit which has excess crankcase pressure. It has later heads fitted etc, it was re ringed when originally put in but I’m guessing it has bore wear. Thinking about buying a recon short engine in either 3.5/3.9 if all the bits will ...

Megasquirt Settings

I wondered is it possible for those with Megasquirt on a 3.9 to post up some settings, particularly the start up settings. Im particularly interested in cranking pulse and after start enrichments as im finding this bit of the tuning quite hard. Im running Ms2 which has the cranking pulse in % rather...

Tweaking stepper motor megasquirt

I have a fitted, running and mapped ms2 system on my Tvr Chimaera. I'm tweaking some settings for cold start. Stepper control is a little erratic, I've confirmed it's movement in the iac test section and am happy it's open and closed. My question relates to the base idle, which used to be set at rou...
