Tnx Ninja,

Yes, tapped all 4 ports and have them come together in one box with some more fittings for MAP sensor, waste-gate, EBC, BOV and fpr. 9 connections in all therefore...

Now I know what I wanted to ask you Wally..where did get those thick gaskets for your manifolds and throttlebodies?

Those were made (machined) from hard plastic 18mm kitchen top material by a friend of mine.
Mc Gyver style

Really?! That´s pretty cool! I would have never thought of that! I hope your wife wasn´t too hard on you for cutting a chunk out her kitchen top

Great upgrades Wally. All appropriate for a 400 hp " 20 min Ring " beetle

Finally I got all parts to install the Sard FPR:





Tnx Sandeep; spring 2010 is already behind us, how is your engine comming along?

[70Turbobug]

Cool! What did set your fuel pressure at? Will you have change your maps or can the DTA adapt and still use the current maps?

[paul_f]

Wally will you leave you fuel pressure gauge in place or will you remove it?

I have the same one, but it says to only use it for setup only and to not drive with it fitted on the box

[Wally]

Mark: it was about 3,5 bar, but the closed loop fuel control of the DTA ecu can easily make little fuel changes if fuel presure will be different

Yep, the same text was on this one. The gauge was very cheap, that FPR wasn't
Not sure yet if I will try it out on longer runs, but I might just remove it and plug the hole after the fuel pressure is original again.
Good eye!

Machined flywheel for the twin disk set-up just before it went in:

Reinstalling engine pics:










I wanted to connect a port from the header to measure turbo beack pressure. From am idea of a good friend of mine, I used an old brake hose to saw off the coupling and just used a regular copper-alloy brake line to connect it to:

I see a new addition. Have you had trouble with the fan belt jumping off Walter?

Good eye Paul. Yeah, it ran fine for two years beating the sh*t out of the engine revving to over 7K, but at the last drag days this year, the belt suddenly came off, mainly in the burn-out box when the rear suspension bogged/squatted.
Hopefully this will keep it on, even in 'abnormal' conditions.

Yep, love my english springer spaniel. We have always had those for as long as I can remember ;-)

Engine runs again and the twin disk seems to engage pretty easy and gentle. Much to my surprise I must admit. It only rattles from the center plate like an old Ducati when the clutch is depressed. Oh, well
Tomorrow test drive to work I was thinking

[Wally]

Test drive went fine: clutch engages really not different than the former one, which is great!
Backpressure is about 50% over boost pressure, which gives great spool but seems a little too restrictive for this 2.2 liter engine.

I need a bigger turbo! (again..)

Next weekend is Spa Francorchamp 'Le Bug show'! Can't wait to finally be allowed to drive the whole track.

[NO_H2O]

Good to see you have overcome the clutch issue. That set up should get the power down. Have a good trip to Spa. I hope to see an in-car video of a lap of Spa.
