RS4 FPRV on K03 - any point?

[sub39h]

as it happens i already have one fitted, but i was wondering if there was any point on a K03? i had it fitted when i didn't know any better

If your present map doesn't request 130bar then it's pointless...

i'm not mapped... yet.

but would a K03 map ever request that much fuel pressure? it has the same HPFP as a K04 car, and it'll never need as much fuel as a K04 as it can never get as much air in, right? so surely a K03 map shouldn't ever be requesting that much pressure?

Revo Stage 2+ k03 map requests 130bar.

Revo Stage 2+ k03 map requests 130bar.

So with Stage2+ remap he will need change to RS4 PRV(As I remember it crack at 136bar or 140bar) to get full from remap?

It's not essential but having the RS4 valve crack at 136bar vs 130 for the standard one may just give a little extra headroom for stable rail pressure.

On my original fprv i had a flat spot at just over 5200 rpm. Now the RS4 fprv is fitted the flat spot has gone. It is a well worth while mod when going more than stage 1.

Is there a fitting guide anywhere?

It awkward to fit yourself if you've not done one before being under the intake manifold. Some folk make special tools or use crows feet but IMO let JKM do it for you as it shouldn't take more than one hour max.

JKM said that an RS4 valve shouldn't be needed, but maybe that was stage 2 k04... they say for stage 2+ it's needed?
