Came back from the "clinic" after a Tek3 session last night.
The car (V6 STi typeR), is standard apart from panel filter and turbo back exhaust with Race cat.
This is was came back with on Optimax (no booster):

Feels better now than before, smoother and stonger (not massively but you can feel it).
Overall very happy with the servive and results
Pat said that he could get a bit more out of it if he leaned out the mixture more (stayed to 11:1 AFR since I've asked him to stay on the "safe side" because I do a few track days) but I didn't want to be that much closer to the edge...

Nice results mate.
Great torque figure aswell

charlesk

More than happy with the results
And numbers don't tell the full story. The car is much more responsive and smoother as well...

Could you post AFR and boost graphs aswell...Makes for more interesting reading when you have all the facts.....

charlesk

There you go. Boost/AFR graph as requested:



AFR 11:1 when on full boost. Max boost 21psi @ 4000rpm, 20psi @ max torque (4500 rpm), dropping to 17psi (just under 1.2 bar) by 6500rpm.
251.3BHP @ the wheels.
Still on STi top mount, and only with a big fan up front and the bonnet shut.

Nice progressive torque curve you have their mate !

hi, I am very new to this so I could just be talking rubbish but I thought these cars had 300hp standard. By reprogramming, replacing cat, exhaust and filter I would expect on a turbo car to see at least +40hp. Am I wrong?

take care,

Some claim 300ps on 100RON petrol,(although Subaru claims only 280ps = 276bhp) By the time you take into account 98 Ron you would be lucky to be pushing above 275-280 as standard.
Also the manufacturer quoted torque is 260lb ft. (again on 100 RON)
This made 318+ BHP and 325 lb ft, which is 40BHP+ over the stated figure, and 65 lb ft above on torque (which is what actually makes a car accelerate).
It is a very good gain consirering it is now 6years old (47-48 k miles) and it was achieved on inferior petrol (98ron UK vs 100ron JDM), on a rich map (for safety) and without traces of detonation.
As I said in my original post I am happy with the result , and the car feels stronger, smoother and much more responsive (almost like a new engine)which at the end of the day was what I was after.

and did you have to change more things like fuel pump, etc to get this figure? What would be the next step tuning wise from here?

charlesk

The full list of engine related mods are:

K&N panel filter
Full turbo back exhaust with 100cel cat
Walbro Fuel pump (the stock STi one would be marginal if not insuficient at this level)
Tek3 Remap
Adjustable FRP

Engine tuning wise, this is it for me for a good while.
I'll concentrate on the chassis now in order to make it more track orientated and to make it suit me.

I would think that if somebody wanted more out of the engine, the next step would be a FMIC, bigger turbo (TD05/20G or similar), bigger injectors and a stand alone ECU, maybe even a set of headers/uppipe. That lot should bring you to around 370-380 relativelly easy, maybe even more.

For me the TypeR is not a drag/street racer. It is a track/sprint/B-road machine that a lot more speed/time is to be gained from a chassis balance that suits my driving style, than another 10-20 or even 60 BHP...
