can i get 350bhp on this set up

vf35 turbo
full 3" decat turbo back
un-equal length headers with up pipe
front mount intercooler
apexi air intake
walbro fuel pump
hks bov
and a remap
manual boost controller

all on a 2.5 turbo wrx hawkeye

 

The turbo may struggle to make 350bhp but it wont be far off, as a side note it will make for one hell of punchy A/B road car.

Banny

 

id be happy with 340bhp put just wondering if anyone has hit 350 mark on this turbo

 

I did yeah.

 

whats your set up?

 

Chris was yours on a 2 litre though? As a 2.5 will make less bhp but quite a bit more torque on the same turbo compared to a 2 litre.

banny

 

yea but i think id rather have more torque but have the 340bhp

 

Your right Banny. Apologise. Mine was on a 2litre.

I was running at the time:
De-catted 3" exhaust
standard VF35
standard 550 injectors
K&N CAIK
EcuTek


Probably not relevant though like Banny says.

 

yea i dont need to upgrade injectors cause 2.5 wrx already has 550's in it

 

id be happy with 340bhp/340 ft/lb torque

 

My 2 litre made 340 bhp, so with headers yours may do better ?

The 2.5 has much nicer bottom end torque tho'.

dunx

P.S. I know of a couple of 2.5's making 300/360 on std turbos.

 

im looking at getting a very good read out then of around near 350/350

 

With the equal headers and up-pipe I reckon it's entirely possible to reach your 350/350 goal.

As said, if anything it'll be the turbo asking the rest of the mods, "Hold on lads, slow down a bit - I can't keep up!"

 

haha yea. i think il acheive a very good result with them mods and a very sharp wrx

 

when you say standard vf35 ,does this mean its standard on some car...

on a 2.5wrx if the vf35 is used ,what else needs to be changed besides dwn/up pipe and reprogrammed...an uprated/sti tmic??? what power at the wheels/proven dyno

 

It's OEM fitment on the Blobeye STi v.8 (and Bugeye STi v.7), I think. The STi Hawkeye gets a VF43.


You prob. would only need Walbro 255 fuel pump, full decat system and remap (don't necessarily need uprated headers/up pipe/new TMIC) to max out the VF35. It should make south of 350bhp...

 

cheers joz,so which would be the best as regards 'bang for buck' in your opinion,the vf35 or the vf43 on the 2.5?what bout the vf39??
so ill be looking at :
200 pump
80 good plugs
1000 decat
1000 turbo
500 map
would the oem clutch last long??

 

is the vf34 a bolt on upgrade for the hawkeye wrx or does it only apply to the older gda/gc8 type...its just there seems to be a really good deal on this setup in some shops.

 

are they prices you have beside them? if so they dont cost near them

 

yeah im just after looking at prices in detail..its only bout half that and itll be around the same as an sti if not a liitle quicker!leaves more money to put into brakes and maybe an sti box/diff..

 

and this is id say threadjacking by now but all info is good right??so what about the clutch,no launches from stand just the odd pull thru the gears when the road permits and out of reach from the long arm

 

If at first you don't succeed, just try another dyno
