hey folks i got my car remapped its pushing 410 with lateral modded >800cc injectors

the mapper said and showed me that at this power level the injectors were at 91% is this normal

i dont have an fpr

cheers

They should make more than that
Fuel pressure regulator would be good anyway
More importantly what fuel pump have you got in?
(Walbor 255l pump maxs out at 450hp)

 

thats what i thought

i have the 255 pump which came with the PPP

it is quite old could this be a contributing factor

 

My std. injectors were up around 93% to make 390-ish @ 4 bar static.

Worth a look, just to be safe, either FPR, pump, or ( filter ? )

dunx

 

Have you ever checked it was actually changed? Not all PPP cars are equal in installation

 

Modded injectors normally need an fpr to increase the fuel pressure, so they can follow what they are rated to. The 800cc flow limit of the injectors will be at a higher than standard fuel pressure.

Banny

 

Totally agree with both these.
Defo check the fuel pump, the PPP where fitted by dealers(exception of WR1) and some are real lazy *******.

 

cheers folks will defo have a look im going to replace anyway as if it was fitted with the ppp

that would have been 6 years ago so replace time

where is the fuel filter - ive heard engine bay do these cost much

Have a look in the group buys section "Anyone GB Walbro fuel pump" ish is the title .On the last 2 pages as Mark at Lateral as added a hi-flow fuel pump as I asked what the limit of the 250 lph pump was and mine has been in 6 years (not with ppp though). As I am at 416 bhp thought it wise to uprate pump.
