Sorry for the hijack :oops:

Rob, you think a set of 800cc's and a walbro would supply enough juice for 450bhp ?

My 740cc injectors where at 95% at 1.5 bar.

I suppose it depends on your set up.

We've set up and run Scoobs with 400bhp using 550's and 4 Bar fuel Pressure (Same Walbro pump as you guys use - GSS341/GSS342) and never had issues - IDC's are about 88-90%.

Just built up a STi5 with a 2.5 block and MD321T running 450 bhpand 450 Torque, she runs 740's @ 4 BAR Static and IDC's are about 87% @ 1.7 Bar.

Surely it'll be easier fitting an Adjustable FPR and setting it up that way?

Remember that even th SARD and NISMO injectors need about 3.5Bar Fuel Pressure as a Minimum or else they end up with poor fuel atomisation and car will lose power.
