Advice on what power i can achieve??? WRX
Please can anyone tell me what BHP i can achieve without the expensive mods .....which i mean as forging parts of the engine internals.....i dont want to do that........
WRX 05 reg 47,000 MILES.
new gearbox and exceedy race clutch.
new cambelt fitted and all other serviceable parts.
sti manifold
sti up pipe
3" straight through exhaust and decat.
sti pink injectors
front intercooler ( normal rad not ally )
apexi boost gauge
hks dump valve
IHI V34 Turbo
TGV deletes
spark plugs 7R
255 Walbro
Aliminium Feeds - K&N (think its k&n) have to double check.
( Unsure if fuel rail lines are standard etc )
open mapped to 322BHP / 290LB torque. ( area 52 notts ).
I am guessing 3 POINT SOLENOID ( which ones best??) and TWEAKING MAP ??? What Power??? (What mapper will push it to its limit but safely) Anything else...........

your turbo should have potential for more, but I have a few questions:
do you have a dyno sheet for this figure?
do you have a copy of your rom with a recent log file to share?
do you run the car on decent super unleaded or regular?
If you look at the boost plot you'll know if you need the 3port boost solenoid or not as it will help you spool a little quicker and hold boost a little longer. If your already meeting your target boost quickly and holding it as long as you need to then you may not see the big improvement you were hoping for. Maybe the money would be better spent on an adjustable FPR to help you get a little more torque?

no problems - they are fairly standard questions to help understand how your current map is setup mr but if you don't want to sure that's no hassles.
I run around 22psi midrange (3500rpm or so) tapering down as it approaches 7000rpm - your dyno should give you a nice flat torque curve from 3500/4000rpm or so up to 6000/7000rpm depending on the map setup, your boost should be fairly consistent in it's delivery (no sharp drops in PSI/bar) until you approach the end of the pull then things will start to slack off.
If your dyno sheet shows injector duty or A/F ratio then you can gauge if there is scope for any more boost without having to spend some money on it. If the injectors are under 90% throughout the pull then you have scope for a little more boost. Now that being said more boost may not mean more power so you'll have to trust the experience of your mapper on that one.

Sorry guys i am new too this so i have listed spec of subaru best i can and asked about the 3 port solenoid and a remap as to what i might achieve....... below is the dyno , someone will make more sense of it all than me as im still learning.

Dunno how Toyosport compare to Japspeed FMIC's but their products aren't really great quality if the up pipes I've seen are anything to go by.
On a decent FMIC a good Vf34 should be pushing 350+ with a good map I'd have said.
Whilst the advice not to chase figures is sensible I would still say that figure is too low of you're certain the components are in good order. VF35's on TMIC's make those figures all day long; a FMIC should see more power.
Have you got a decent turbo inlet hose fitted? You might have a leak if not as the plastic ones are notorious for tearing.
Btw you don't need a 3 port to make that power it will help fine tune control of boost but shouldn't inhibit the car from making good power.

Not wanting to sound harsh here, disregard all the advice anyone else has given you.
And take this bit of advice -
Get the car in for a health check, oil change etc, get someone to run it on the dyno and check the map etc.
Once all is good. Go out and learn to drive the car properly before you start trying to get more power out of it if it is your first car like this. It is faster than you realise....

The front mount alone isn't going to be adding any power for you, but the 3port and a remap should help bring the boost in a little bit sooner. Though you will be better off finding a mapper and talking to them about your setup and what can be achieved. If they are worth the price they are charging then there should be no hassles in answering any number of questions you might have beforehand.
