My MK1 3.2 TT Turbo

Standard only around 240hp IIRC but the DSG meant you could just plant your foot and leave it flat through the gears which meant it was quick off the mark and the 4Wd made it easy to get the power down.

I will still be able to leave my foot planted and let the DSG change the gears, but i dont know how freightening that will be.

Can the Dsg handle 500hp without disintergrating, thats more than double the power of a standard 3.2. Thats got to be some amazingly quick car.
I used to be on the TT forum they have weekends at places like donnington park, and you can buy performance parts for your TT. Even had a parade lap of 120 TT's when i was there.

The engine is capable of 800bhp at the crank on pump gas and the DSG has had the clamping pressures maxed out and the load shedding feature has been removed. If the box goes terminal then it will be swapped out for a manual conversion but i want to see what the potential of the DSG is. Ive already had 537 bhp crank power through it and it was fine. Its time to up the anti.

There are lots of weekends out for the TT Forum and at some venues there are organised sponsers there selling there wares, but you are very much mistaken if there is anything there for me, as these peeps only supply for the mass 1.8 market. The majority of my parts would have never gone near a 1.8 TT as my build is more radical.
If youve read the build thread you will see the complexity of the build, there are more similarities with the R32 boys who go FI but they havn't used a charge cooler or SSP clutches.

Im normally not fan of TT, but that is awesome build. Enjoyed reading though it.

Cheers, this is not a normal build that is done every day, esp the way im doing it, so i thought it would be better to share.
The next 4 weeks should be interesting, when we get it out on the road and do some running.

Well..
The ECUs are in customs at London.
Unitronic have had some brilliant results on their test bed engine running Stage 3+ components.
Destruction testing and then producing the final version of the files took a little longer than expected due to the complexity of the changes required and Canadas public holiday system.
The software includes a tune facility that Autograph will utilise to tweak certain parameters once some logging has been done on da mota.
Two valves and bronze guides in the cylinder head have been replaced and compression testing has shown good seals.
Due to various and speculative reasons the block has had all oil seals replaced and was bored by 1mm to ensure a 100% good starting point. This takes the CC of the 3.2 to 3.3 now, which is within the tuning parameters of the Unitronic files.
The crank has been checked for balance/trueness and has been polished. It was found to be within tolerance.
6 x 85mm Wossner pistons [coated skirts] and rings have now been introduced to plug the gap in the block.
6 new spark plugs have been installed utilising the spec of Unitronics test engine.
6 new ID1000 Mitsy fuel injectors have been installed to match the potential of the engine.
The TT is now running a turbo hybrid of Garret and ATP..GT35/T04z with the antisurge compressor housing.
A larger wastegate has been installed to allow better control of the boost.
A stainless flexible hose has been installed between wastegate blow off side and the exhaust to allow for expansion.
Ceramic coating of the DP and WG hotside will be done when possible.

Brake master cylinder has been replaced due to perished seals on the old unit.
A new DMF has been installed as the OEM one had 15mm of play in it and 1-2mm is new.

Results from Unitronic have shown that the test bed engine is producing 740 bhp at 16 psi.
The gearbox ECU will have some OEM features removed or maxed to allow for the most torque we can get through the box.
The clutch is able to run 600 lb/ft so..if the box goes terminal, it will either be replaced or a manual conversion installed.

Unfortunately the dents/dings won't be pulled before i pick her up so the wrap will be scheduled for when i next go offshore..
I may have to pay if i want my wheels changing to the Rederwerks one-eleven S as ive had my freebie rims.

Come say hello if ya see me.
The TT won't be wrapped this time round as prep and wrap time are about a week or so and ive ran out of time to get that sorted.
Steve

[V6RUL]

Yep..your correct on the turbo connections and external wastegate connection.
The turbo is now a hybrid with at least 1 additional feature as seen here with the anti surge compressor..

Here are some pics from a few weeks ago.
The engine is back in and just the rads and bumper to fit back on, obv with a bit of plumbing and life blood to pour in..




Charge cooler rad in front of the engine rad..


3" Exhaust before it gets the granny scarrer fitted..


Ive received a few bits to put on the TT to help with aero improvements on the front and just general bling..






I will be going back to a twin exit exhaust..hence the valance.

She is running on very low boost at the mo until she is run in.

Hi guys,
the car for sale is Storms TT and manual.
Im sure theirs is a very good example of a blown 3.2.
Mine is a 3.3 with a T04z hybrid hooked up to a DSG.
Unitronic have had 740 bhp at the crank at 16 psi on their mule.
Mine should be dynoed at the end of the month to see what numbers were getting.

ps The oil cooler is installed correctly and due to the pressure differential across it, air is pushed out.

Epic power and car mate!



Btw, a little off topic but are the MK1 TTs (225 quattros) tending to suffer from rear diff issues at all? I heard there are, albeit earlier models? Just been looking at them, quite fancy one

Rear diffs are ok, but it depends if the car has had any abuse.
Some peeps fit the performance Haldex which applies more load to the rear which may have an effect on reliability.
I have one fitted and my rear diff is ok at the mo but i may be changing it out for a Pel in the future.
Steve

I think forgetting about the rear of a Quattro car is a big mistake as there are times when 50% of the drive is going through the rear axle.
If the rear locks up whilst on the move, through lack of maintenance, then you get what you deserve, incl a rebuild cost, nevermind what damage you may do to third parties or property.

Cool build

What do you mean by a Pel ?

Peloquin diff for the rear as i dont believe there is a Quaife available

Steve

one of these babies

The one on the right is the rear transverse diff


Works very well with Blue Haldex. Does very little work compared to the front diff tbh
Replaces the transverse open diff which sits behind the Haldex Clutch, and doesn't replace the Haldex.
Its the pump that engages the plates in the haldex clutch that can get worn iirc.

Got mine direct from Garry Peloquin

Cheers..i was after Quaife front and rear but that combo isn't available so half and half was my best option. Maybe i will reconsider doing Pels front and back, but i will do my homework first.

The Peloquin is better & cheaper than Quaife.

Both my front and back diff cost less than a front Quaife in the UK

There are some others options, such as SQS's plate (gripper) front diff

The Peloquin's extra traction is significant

Edited by snowmuncher on Thursday 20th October 18:45

I will certainly consider it as there are a few outlets in the UK that can supply and fit.
Havn't got to the point yet where traction is an issue as im still running her in.
Steve

[V6RUL]

Ive decided that 2 is better than 1..

Here has what has been added by Pipewerx for when i need decent freeflow..

The bypass is operated via an electric switch in the cabin.
