hi,

wich one would you prefer and why?

thanks for your help.

 

VF35

Because it gave me 333BHP!

F

 

VF34
because it gave me 348 bhp !!

with supporting mods the 22 would give you more bhp but its more laggy than the ONES YOU MENTIONED

or consider 1 of andy F's td05 18g

 

scoobydazza, can you write what mods do you have? and what's your scooby model?

 

none of the above.........TD05..16G,18G,20G would be a far better investment IMHO

 

And what boost your running to make the 348bhp.

i've got a vf34 on mine, but haven't had it rolling roaded yet, i'm running 1.35bar

 

1,35 bar? what mods do you have? I was thinking in 1,2 bar... it's what I'm runing with the oem turbo...

 

VF34
FMIC
3" full de-cat
Blitz induction kit
uprated fuel pump
Areomotive Fuel pressure Reg
Blitz Boost Controller
Forge VTA BOV
Andy F Tek 3 Remap.

 

with stock internals? you never had problems?

 

Vf 34
aps cold air intake kit and FMIC
Gruppe-s headers ( lagged of cause)
scoobysport downpipe, Magnex centre,Blitz Nur-spec back box
Walbro pump, FX fuel regulator
550s injectors
Motec pro M800 ecu
360+ bhp

ps still on standard internals ......and going stronge !
Clutch is the weakest link !

 

Apprantly stock internals are good for 400Bhp even on wrx/uk turbo, it's the clutch and gearbox that are the weak point's. I've got an uprated clutch ready to go in when mine goes. Gearbox's are at there limit at about 350bhp.

Thats why i went for the Vf34 over a TD05 18G, as i was told that would be pushing my luck.

Check out www.andyforrestperformance.co.uk there is some interesting infomation on there.

 

thank you for your replys, they helped a lot.
a remap is always necessary ins't it?

 

Not "always" necessary but would be recommended.

I ran a vf34 on an MY99 UK turbo at 1.4 bar on a standard ae802 ecu for 1 year 15,000 miles without a problem. This was with knock and wideband AFR monitoring, higher fuel pressure, octane booster and 2 degrees of blanket retard across the map (using deltadash).

Now have Power FC (AndyF mapped, continuously tweaked by me ) running 1.55 bar. It feels much better/smoother/stronger now, and I've worked a lot on the part throttle/boost areas of the map. Driveability is so much better than the standard ecu.

Be warned though, that sort of boost breaks gearboxes. I stripped third a few months ago, now have a MY02 WRX 5 speed which "may" be a bit stonger. We'll see
