Getting tune... Guess the numbers

Recommended Posts

Im getting my tune done on Wednesday by Chris at prestige tuning sooo lets play the guess the kw/nm game. V7 Sti

3 port boost solenoid

3 inch belmouth catless downpipe, 2.75 catback

320lpm fuel pump,

K&N panel filter

Clubsub sticker +10 kw

Currently 177kw 335nm. I would be very happy with 210kw 400nm so thats my guess. Assuming the clutch, 3 port and downpipe is successfully installed on Tuesday...

The tune will hopefully get rid of the knock too...

Gonna be a dicklord and say sub-200wkw.

Mostly cos I don't know that dyno worth a damn.

It was tuned by Chris at STM but that was a different dyno. They're all Dynapacks and they should all read pretty much the same but they just don't.

I'll say 197wkw and 400Nm if the tuner goes for numbers for show then just over 200.

 

it comes down to if you can hold more than 14psi higher in the rev range, so waste gate control and pill size are big factors with stock turbos.

 

if you still have tmic then you get higher peak figures keeping the boost at 14psi the whole range. The heat at 21psi limits the top end since the intercooler doesn't cool fast enough affect the end of each pull (or temp sensor is slow reacting). But since the result is down on peak torque and the peak hp will be later in the rev range it won't be as good to drive.

 

either way you have a lighter car than the later generation so 20wkw gain will feel huge!

212kw & 395Nm

 

I'm guessing rising intake temp will be the limit if it is as hot in Wellington as it is here right now.

I guess next mod would be fmic or big tmic

Wait and see if the tune goes well and how you like it afterwards before you worry about the 'next mod'

When the mods stop, sell the car or get another one to play with.

Not exactly, the stock boost on these cars is about 18psi. Tuned ones regularly pull 20psi+ all the way to the redline with a 3-port solenoid and no other boost control modifications. I think mine peaked at 22psi when I was using a turbo this size.

231kw and 500nm

I got 231wkw on a tune by this tuner with a VF34 and pretty much every bolt-on stock-location-turbo mod you can do, big (quality) TMIC, silicon under-manifold intake, tuned length headers, proper cold air intake, Link G4 with AFM delete, blah blah blah. Also way less than 500nm. You get peak torque at about 4000-4500rpm off the top of my head and 500nm there would be about 235kw (Garrett GTX or EFR kinda numbers); peak power will be at somewhere around 6500rpm and the torque will have plummeted by then.

If he gains 53kw from a tune I'll be staggered but crazier things have happened!

Yep ive staggered alot of people with mine thats why im not suprised at the power gains stock subarus make. So much hidden potential

@StrokedEJ blah blahs add lots of power.

 

Port matched manifold and new air intake could be 8-10wkw. It's those little improvements that allows the bigger mods to perform there best. Also allows reduced timing up high with improve airflow.

motor could be worn, too many factors. Luck of mass produced things some are better than others.

Faaah route its a guess game not an engine science class

i am thinking around 210 - 220KW at the wheels, i did the exact same mods to mine and made 220kw @ the wheels, all the best!

depending opn engine condition maybe 220kw as that seems to be what we get out of v7 sti..

altho sometimes some cars do wonders .. hoping ur one gets some solid  numbers..

keen to see
