Power boost valve

[doomvolvo]

Just out of interest if I ever get my volvo back on track Has anyone fitted an FSE power boost valve to a 2.0? What kinda gains will I be looking at and what effect on the economy should I expect?
My friend put one on his clio 1.8 16v and it was quite impressive but MPG was disturbingly low

[bb54]

ive fitted one on a rover 600 turbo, saab 9000 2.0 turbo, saab 9000 2.3 turbo
and two 850 T5's.
i swear by them, just makes the car more responsive basically.

as you can see by the cars i drive..... good petrol consumption isnt one of my priorities ! lol.

ive been asking the same question about these for my 2.0, after reading your post saying you swear by them, im now going to get one, would it be advisable to get one with the preasure gauge ???

hi, an FSE power boost valve is an 'uprated' fuel pressure regulator, it has nothing to do with turbo boost mate if thats what you meant.

if talking turbo boost increases ??? maybe you mean an MBC... manual boost controller ?

ive bought 4 FSE regulators and ive never had an option of one with a pressure gauge.

can you turn the fuelling down with an FSE, i know BT's running rich so would want to adjust to to get the best mixture

many thanks Duane

Late response, but better late than never (sometimes?).

These guys supply the gauges:

Theres also a company in germany selling them on ebay with the gauges actually attached as part of the unit, about £40 i think but never heard of the make.

not a bad price for the valve either, i guess the GLT turbo is the one for the T-5

hi Duane, yes you can lean up or enrichen.
anti clock leans up the mixture.

the bumph with the advert in the link says they are preset for each application, but myself and everyone else i know that has fitted these have allways clock turned the adjuster screw to get the best throttle response.

the info supplied with the FSE says that a clock wise adjustment will be needed for best results, but in a limited no of cars, a anti clock adjustment will produce best results (no vehicle details).

my 2.3 9000 FPT is the only vehicle ive fitted one to that required anti clock (leaning) for best results.

ive found that there is two types of power benifit from these units, depending on the adjustment screw position (not lean or rich) , but say the screw is pointing to 15 minutes past the hour (minute hand), it will give rapid acceleration from standing start, move it to 16 minutes PTH and youve got normal acceleration from standstill but you can feel the extra pick up higher in the rev range.(very sensitive adjustments)

i always go for the low rev option on a turbo ,cos the turbo takes care of things at higher revs.

its a case of fit and play until you find the best setting.

on my phase1 the adapter fitted into the old fuel press reg hole with no probs, but when i swapped it onto my phase 2 ,the bracket interfered with injector #2 and i had to saw a corner of the adapter off to get a snag free fit.

if any1 wants a pick of one in situ or would like to read the info sheet supplied, let me know and ill try to load it up.

they are a swine to work out (fitting instructions are naff).

i cant work out why you would want a fuel pressure gauge myself, unless your running a very special piece of kit.

ps, the prices you found are very good, under £70 wow, mine have all been £100 and £110 for my T5.
