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...:shocked: ;)

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 :D

Sandeep July 3rd 2010 09:10

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

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

70Turbobug July 10th 2010 12:45

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 July 10th 2010 12:53

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 July 10th 2010 14:33

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 :lmao:
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:

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 :D

Wally July 18th 2010 06:41

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! :D (again..:o)

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

NO_H2O July 18th 2010 08:14

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.
