hi there just had the car mapped by duncan and very happy with it but all ready want a little more power. duncan said its making around 320 bhp but want it making near as possible to the 350bhp mark. its a 2005 wrx with,

japspeed fmic
3 port
pfr7b spark plugs
full miltek decat exhaust
pink injectors
decat uppie
walbro fuel pump
vf35 turbo

was thinking of a sti manifold with the tgv deletes but what else will i need to make the 350 mark ?

what headers have you got?
induction kit?
up-pipe?

would have thought the vf35 would make more to be fair

scoobywrxjoe

iTrader: (1)

standard headers
just used the japspeed induction kit they supplied with the fmic
not too sure what make up pipe is but its a decat 1

the shreksta

iTrader: (20)

maybe swap the standard headers for some havey/as performance ported and wrapped headers and maybe try a different induction kit like roger clark etc

have you spoke to duncan about it? has he kept the boost low?

scoobywrxjoe

iTrader: (1)

no not spoken to duncan thought i would get some info on here 1st before i bother him. so a good induction kit would change figures by much then ? where can i buy the havey headers from ?

the shreksta

iTrader: (20)

as performance (alyn) does them along with a trick up-pipe,probably wont gain alot more bhp but will certainly aid spool time

as for induction kits im not sure but i would have thought that the rcm is better than the japspeed.

is your exhaust a full 3" bore de-cat?

ive heard of vf35's making 350bhp so it is possible,i would drop duncan a pm as he is very helpfull mate and remember its not all about numbers its how it makes that power,you may only get it to 320-330 bhp but with it set up properly with good early spool it should make for a very entertaining drive

yeah its a full 3 inch exhaust decat all the way.

hks headers any good

The 35 responds very well with a ported wastegate which is to be honest an essential modification to this turbo as it suffers from boost creep with a full decat, back this up with an uprated actuator set between 0.8-1.0 Bar and you will see good results even on standard headers.

where and how much to get this done?

Big 'D'

I am based in Lyneham Wiltshire, the porting is fairly cheap mate but the actuators cost circa £150 new, I only use Forge.

Cheers Iain

Ok I'm gonna open a can of worms here but this was tested on 3 rolling roads - andi won't go into it again !

I made 379 of that turbo with the following

Gt2 spec hedders and harvey up pipe
3" down pipe
Nur spec r 3"
harvey FMIC
Andrew Carr map

The vid is on here somewhere !

Big 'D'

Can you post a graph please mate? Boost/BHP if possible

blackpoolrock

Don't want to post on this topic but it is on here somewhere and the 2 axis do meet at the correct point !

Big 'D'

Can you PM it to me then please, I am genuinely interested.


Cheers Iain
