Fuel pump capacity for boosted Dc5

[Jonnyteg]

I am in the process of going for a rotrex setup C30-94 which should give near 400bhp, does anyone know if I will have to upgrade the fuel pump for the bigger injectors?

Yes you will need to upgrade it.
Most people go for either a Walbro 255 or a HRC 255 LPH

Yes you will. Oem fuel pump will reach its limit in the region of 320-340ish hp.

Thanks guys

Mine is 370 & has a uprated fuel pump. If you buy the kit it will come with it

 

[Jonnyteg]

What setup do you have?

Also building a new fuel set up to be sufficient to go boosted

What setup do you have?

The TTS DC5 Rotex kit (I can't find the invoice to say which pump I have but when I do I will let you know)

Yeah I have spoken with TTS, I will need a fuel pump. How quick is yours with 370bhp?

How longs a piece of string? Pretty sure it would be an animal

Depends if you have a return fuel line. With a walbro 255 and no return line it will max out at 360bhp. You need to get a 400 litre per hour to get past 360bhp. Also advised to run power direct from battery with relay so got a good power supply. If you have a return fuel line a walbro 255 is apparently big enough.
