Since my last dyno session I've found that the old Weber 800 is too small for the Rover V8.
I first fitted a Weber 500 when the engine was carb + nitrous.
Then went up to a Holley 600dp for even more nitrous fun.
Then fitted the supercharger and needed more so fitted the Weber 800 cfm carb.
Now it seems that the new engine needs more still. Its a pretty well sorted engine and I've worked on engine VE of 90% at 5800 rpm. The new lump displaces 4.8 litres now. When i add in the boost factor calculation for the 13psi i want to use I need about 950cfm from the carb. So I've just got a Holley 1050cfm Dominator.
Its fookin huge !
I've just ordered the adaptor from the states to make it fit the blower.
No prizes for guessing which is the new carb
