just picked the car up.....hmm bit of info please.
 

Wow, car is pulling hard now. :luxhello:
Had vf35
Sti pinks
sti top mount with better scoop undertray from aps
decat up pipe
Ecutek remap
Now the car does pull very hard but i have two gripes that i don't know if i should have....

1. The turbo is very laggy, no real boost till i hit 3200rpm, and full boosting at 4200rpm.
Is this normal with the vf35? Got it second hand, so i can't really make a judgement on what it should be making.
2. The turbo is making 1.6bar boost and settling at 1.4ish bar.
I always thought 1.3 was the limit. :Suspiciou

Need enlightening from someone in the know!!
Thanks in advance

1.6b is abit too much for a VF35.

Exactly what mods I am doing, Ill be interested to hear how the car is meant to run! Quickly hopefully!

I'm guessing Clive mapped it when he fitted the bits? Post up the graphs mate, Should give a lot more info.
Glad your happy with the extra power :)

what up-pipe are you running?

One clive @ clive atthowe tuning sourced for me as i'm on a little bit of a budget at the mo. (just bought an engagement ring....gulp)

Will go take a pic of the graph and post it up in a minute micared. :thumb:

as the tuner sourced the up-pipe i would assume its of a suitable size diameter, a friend had his wrx mapped with exactly the same mods and the lag was terrible just didn't seem to want to go, that was down to the up-pipe being to large.

Possible, however i was assured the pipe was good and i wouldn't have any issues with it.

right here are the figures i was given

Both Clive and Dan @ clive atthowe tuning were involved in mapping this car.

Let me know what you guys think.

My old MY00 classic had the same mods as yours but was mapped to run 1.2 bar and it spooled up very quickly. I hardly had any lag. Steve.

Crapping myself that i'll damage something running this high a boost setting. Going to jap show on sunday, don't know if i should 1/4 mile her in this guise.
Plus i'm now poor for a few months, i'm going away to Rome next week to "pop the question to the missus" crapping myself with that too!!

looks abit laggy compared to mine im pushing 180ftlb at 3000rpm but im running boost controller and 3port + the outside temp is 24.5c this wont help

What up pipe are You running mate??
Did i mention the turbo was second hand? might have bought a lemon zest turbo :cry:

gt spec headers and uppipe 1.8bar on my vf35 but its had a build

Think i need to give harvey some money. :( then if that doesn't work, a new turbo. :(:(

Oh and i have a 3 port too.

go out side and find out what up-pipe is on it first before you go out and spend on a new up-pipe and a map tweak, have you raised you concerns with your mapper??

He said it's the turbo thats laggy. Clive described it as "this turbo seems to be particularly laggy" He's mapped lots of Subarus so i took his word for it.
Then upon driving home i rang and was told he's on holiday for 10 days to Las Vegas. So i guess i'll have to wait.
Wen't out for a drive to collect the missus from work, and when it's on song- my god....the power!
Just wish i didn't have to wring it's nect to get the ooomph.
I'll check the pipe in the morning as the bloody engine is hotter than a nicked dvd player being flogged by Satan himself!
It looked like a slip joint jobby though. No flexi point or name stamped on it that i could see when i first looked.
You recon i could get a pic of it? or is it buried in the deepest darkest depths of the engine bay???

yeah get a pic if you can as it always helps, try if possible to get pic from underneath if that will get a better view.

does seem quite laggy for a vf35 mate,i was running 1.42 bar and it spooled up really quick.

has to be exhaust leak, intercooler leak, or 2port / way it has been setup.

Simon

VF35 is not a laggy turbo in fairness, classic up-pipe or newage sti job would have been better, most aftermarket up-pipes are way to big and some are cheap dirt that will fall apart.

If your on a budget try a classic or newage sti up-pipe. If you have a few quid get one from Harvey.

Thanks for all the replys guys. Couldn't get a pic of the pipe as it's buried.
However i can hear an...as best as i can describe it "chuffing noise" from under the turbo, so this is really starting to make me think that it's the up pipe thats the problem.
On another note, 1.6 bar and settling at 1.4bar.....is this too high for a standard internal engine?!!

WRX YES ! STI NO !

HTH

dunx

P.S. It does sound like the up-pipe to turbo gasket is "chuffing", you could try nipping down the nuts if you have the tools.

How is boost measured? Make of gauge?
Some over read.
Imho seeing that late spool it should have been checked and the issue sorted / identified etc.

Tell me about it! Paid alot for their work, and this is happening. Not a happy bunny.
Make of gauge Prosport.
Never went over 1.3 bar when Simon mapped it.
Now gauge reads 1.6 bar on WOT and settles to 1.4 maybe 1.5 bar.
I would think fitting the up pipe THEY supplied, that they would also fit the required gaskets e.t.c! :mad:
Paid £1220 for this work in total.

Maximum psi reading on the above pics reads 22. Converting to bar reads as 1.52BAR!

New Turbo setup 1.4 to 1.5bar peak on road is fine.
Boost on dyno often reads lower ie. It will boost higher than that graph on the road if not tweaked on the road.

They apparently dyno'd it, then double checked on the road.
Think i need to buy a harvey up and take it somewhere to get it finished and then simon to map straight after.
Not easy/cheap i suspect.

Right....update.
Got the car on the ramp this evening and pulled the undertray down.
Started the car up, and with the highly advansed technological break through of fairly liquid, i managed the find the up pipe gaskets leaking badly (looked like a bloody bubble factory)
The gaskets look old, like they re used the old ones. :razz::mad::mad:
WTF?? are they for real?! :cuckoo:
Think stern words are required for tomorrow. :nono:

glad you found your problem, its a bit naughty reusing the old gaskets on a job like this where they take time to change, pus the car will need a tweak with the leak fixed.

Good find, at least it should be their responsibility to put it right.
