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

 

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

 

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?

 

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 ?

 

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.

 

yeah will give duncan a message later and see what he says

 

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.

Cheers Iain

 

where and how much to get this done?

 

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 !

 

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

 

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

 

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


Cheers Iain

 

Will do may take a while to find it ! Think the topic was called on the rollers !

 

ok should be able to do the porting my self will have a look into this
