Hi Guys

My friend's 333i is only revving to 5000rpm. We can't find the problem and we are desperate to find a solution.

If anyone can help please, We will appreciate it.

Could be many things. Guys will need more info such as:

Is it running stock ECU and AFM?
Is it a drop in power or a straight cut like a rev limiter?
Doe it happen at any throttle position or only at full throtttle?
Does it happen every time or only when hot/cold/or when you reach a certrain gear?
If you are using an after market EMS, what is it?

You sure the motor isn't reaching the rpm limit but rev counter displays incorrectly?

Happy hunting.

the lift pump in the tank might be dying

with the right outside pump one can run without a lift pump rs is running his v8 like that
the lift pump has a 10mm line the in-tank pump ones 8 mm in the fuel tankitss basicly up to what one wants to do run a intank high presure one or outside one the choice is yours

I would prefer changing the outside pump to a more powerful one. Which pump is recommended and what type of modifications needed to fit. Thanks for the help Hennie appreciate it. :)

completely eliminates the external pump and the lift pump in the tank.

+1 - What model are these cars with the problem? Is the 323i the one with the dizzy still on the side of the engine> If so I suspect that it has the rev limiter built into the rotor, same as the M10 318i motor - it's a plastic grommet and spring arrangement sitting on top of the rotor if this gets old the revs can be limited as low as 4000 rpm. When you yank the spring and grommet out with a pair of long nose pliers the danger ... and fun is that the car will have no rev limiter at all :D

Update on the problem I had with my car, it was something simple and most easily overlooked - the fuel filter on the suction side of the external fuel pump was blocked/semi-blocked and therefore imitating much more serious problems such as a faulty Fuel pump, FPR, AFM, TPS plug wires name it!!! Fortunately I only replaced the fuel pump and the fuel filters when I found the very dirty in line fuel filter wihch I have installed before the fuel pump lnlet. Next on my to-do list then is to try and drain all the dirt out of the petrol tank.
