Welcome along. Well done on braking a rod. I don't think anyone in the UK has amanged that yet

bienvenue my friend, i'll bet that goes like shit off a shovel! Big Grin

Excellent work.
Good to see the XUD11 in a 205, not seen that before.
How does it handle with the big engine?

This sort of swap is very famous in France!

The torque is crazy. And handle very high but the setup is not ready for the full power. 

I have some adjustements with the front frame. And for the moment the turbo is not managed by my electronic boost controller. But engine is very powerful yet Smile

Awesome Big Grin Did you fit a Bosch pump or keep the Lucas?

RE: 205 GTi 2.1 TD - XUD11T - Biggen - 09-06-2018

Yes of course Bosch is the best 494 9mm original with mods inside.

I m making a new 11mm for the next stage

My exhaust manifold

   
I prefer to pass the intake pipes under the engine, for more space over

   
The flywheel is lightened -2.2kg

   

RE: 205 GTi 2.1 TD - XUD11T - Biggen - 19-07-2018

I designed this new aluminium pulley for xud11T and 2.0 HDi, now it's 520gr against 2.2kg before.
Available for who wants the same.

   

   

   

RE: 205 GTi 2.1 TD - XUD11T - Ruan - 20-07-2018

Looks good!!!

I'd strongly advise fitting a later 206 or 406 HDi alternator with that pulley if you can - it will prevent damage to the belt, idler and dampener. With the engine rotating assembly so light, the inertia in the heavy alternator can cause damage to the belt. That's why HDis have a rubber pulley or a freewheeling clutched alternator instead.

RE: 205 GTi 2.1 TD - XUD11T - Biggen - 20-07-2018

Ok Ruan. Thanks for the advice. But are you talking about the timing belt or the alternator belt? Not sure to understand....

RE: 205 GTi 2.1 TD - XUD11T - Martin306 - 20-07-2018

He means your alternator belt.

The alternator will become too heavy to turn because the drive pulley is so lightweight, the belt will slip/vibrate etc and become damaged.

Newer alternator from a 406 HDi has a freewheel alternator. It has a "clutch" on it which operates one way. a bit like a bicycle wheel.

RE: 205 GTi 2.1 TD - XUD11T - Biggen - 21-07-2018

So the risk is only to brake the alternator belt.

I run like that during more than 5000km before with my first R.I.P 2.1td (standard conrods broken).
And the belt is still alive.
Do you have picture of the 406 hdi alternator?

The risk is to the belt, alternator and the dampener - it will be made much worse with the lighter pulley. You can usually tell the clutched, freewheeling alternators as they have a cap over the pulley like so:

It will also help the engine's response as the the alternator can spin down freely, so the engine revs fall faster, meaning faster gear changes etc.

RE: 205 GTi 2.1 TD - XUD11T - Biggen - 24-07-2018

Thanks a lot for this information, i have never heard about this new technogy. I know only the old engines...hahaha

But I will test like that. I have never got problems before. I will let you know.

The revs already fall faster with 5kg less on the crankshaft....
