When you want to make power and not worry about fuel delivery you need one of these bad mofos

Have a look on Powerflex website
They name all the arms on a diagram
Then speak with Clive or them I guess

I’d say 7 as it shows the arb going over it
And right hand side shows lower front wishbone on front

Just for knowledge...

Regular fpr on the left, mechanical pump driver fpr on the right

The mechanical fuel pumps work on vacuum so they will suck the fuel out of the tank whilst cranking the engine, puts a demand on the battery but I'm using a 16volt battery, as I'm not bothering with an alternator.

Iv seen a few drag cars wire an electrical fuel pump up with the starter motor so that the engine gets fuel pressure faster and as soon as it starts the mechanical pumps take over.

Mechanical pumps are so much better in my opinion as there's no electrical load and wiring to worry about and you should never run out of fuel supply

The amount of fuel flowing increases with rpm, mine can do 12.9 gpm at 8000 rpm at 100psi.

Fuel pressure will be the same same as any rx7, 38 psi base pressure? And then increasing along with boost I think so I should see70psi fuel pressure. Plus iv got more volume in the fuel lines, think I'm going for - 10 or - 8, can't remember at the moment
