TURBO DIFFERENCES ?

[martynx]

Ive noticed that Mk6 tddi turbo's are conveniently marked with their power ratings ( & engine size ) by a sticker on the top. My 100ps FWD 2.0 fror expample reads 10020 & my 90ps RWD 2.4 reads 09024 gives the game away niceley..!

As the units look externally the same what are the diffrences ? is it just wastegate opening time & therefore a higher boost "setting " on the higher power rated ones ?

I appreciate front wheel drives are different overall to rear wheel drives & that increasing boost to raise power safely would require remapping to increase fuelling etc -

The wastegates arent electronically controlled ( they are controlled simply by a pnuematic valve via pressure from the compressor side of the turbo ) so therefore boost isnt controlled directly by the ECU.. from 75ps to what is is 115 ? sureley boost must come into it ?

Some wastegate valve rods are adustable , tempting isnt it ?

Tempting till the ECU says f**k off

I'll be remapping his silvered ass so little danger of that

A simple re-map will do

NEVER interfere with the wastegate on a vehicle with an ECU

Hypothetically If you had a 85ps & put a map in it from a say a 115 along with a turbo from a 115 then you'd get the 115 i guess.. the intercoolers look the same , the pumps are all Bosch Vp30's ? with diffrent settings..

My idea is that instead of getting a 115 turbo ( expensive ) match the wastegate setting to the 115 spec., provided the units are the same other wise.

Fair enough if it isnt possible, its just that the wastegate system looks so old school simple .. im just wondering if the wastegate setting (& therefore the physical boost setting ) is the limiting factor.

I guess one of these would save any messing around with springs & stuff

What is the highest tddi output anyway on a 2.0 ?

[AndyG]

No, no, no

JUST A RE-MAP


The turbo/wategate etc takes care of itself

The ECU does actually read how much boost there is

If it's too low or too high, it will put the vehicle into "Limp Home Mode"

Fair enough Andy.. !! i'll do my best to keep the toolbox shut.. - if you see a met blue SWB with its hazards flashing on mahjacks roundabout you'l know i ignored your advice !!

I'll keep an eye out (if I knew what roundabout mahjacks is )

(if I knew what roundabout mahjacks is )

It's the large roundabout at the end of Windsor Street.

It used to have a large hardware store called 'Mahjacks' in the middle, but now has a large nondescript office block

I think I know where you mean now Parking ticket land nexto the shops

[Altransit]

:oops: I think I know where you mean now Parking ticket land nexto the shops

Nope.

It's the southern end of Windsor St.
Has about 6 sets of traffic lights going round it, and Kwik fit are on the south eastern corner.
You wouldn't want to park anywhere on it

Kwik Rip I know where you mean now
They wanted over £120 for a 195x14 for my van And wasn't even a Michelin Agilis
I made them double check and they gave me the print out

Costcos half the price (or "buy one get one free" )

Ha ha yeah thats the one .. though come to think of it i never new why i was was called mahjacks, i used to use a a car paint supplier called morellies there 10 or so years back...

Couldn't remember their name, that's it, Morrelli's.
They were right next door to Mahjacks.

Morrelli's were moved to the Wallingford Road industrial estate, but I don't know what happened to Mahjacks. probably suffered the same fate as most hardware shops .................................. gone
