ive fitted a 1.3 rallye inlet and at full throttle it wants to cut out...so i were a tinking.

if i put my vts fuel pump in my vtr (as i belive the vts pump runs at a higher pressure) that it would pump more fuel in quicker, hopefully the cut out at full throttle would stop.

also have a pair of vts injectors but are they not the same size as the vtr?

anyone got any thoughts on this?

Doesn't really matter what pressure the pump runs at, as the Fuel Pressure Regulator controls the pressure (assuming that the pump is in a decent condition and is capable of getting the pressure higher than the FPR at high revs).

VTR FPR is 3.5bar, VTS FPR is 3bar.
