Where do you take your MAP from Wally, have you drilled and tapped the manifolds?

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...

Finally I got all parts to install the Sard FPR:





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

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?

I have all of the parts to put the long block together, and all of the induction system, and electronics but still have to build a horizontal fan set up.

My biggest issue right now is finding a twin spark knock control system, and until I find something that exists / works like a J&S, I am not in a rush to build

PLEASE post some video of your runs at SPA.

Good thinking. By now I know its almost only one thing that breaks a turbo engine and that is knock, so I hear you loud and clear. Wish I could help you with an idea, but I haven't got one yet..

No worries about the vid of the track driving. I hope somebody also films from the stands so you can see more bugs driving by on the track
I have the Water/meth tank filled up, brought some spare 98/93 with me and am packing my camping gear.

And I hope it will stay dry weather...

[Wally]

It just doesn't get any better then this...





Saturday was a 'mildly moist' condition and I did 1,5 hours of non-stop track driving.
Sunday was a beautifull day at Spa and track driving in the dry was so much more spectaculair. We drove one hour full on and the engine held in at only half an hour as it was already then short of fuel (25 ltrs gone)
I only filmed saturday as I left the camera running till the disk was full (26 minutes). Unfortunately, that also doesn't work with youtube (max 10), so I'll have to cut it somehow. Will take a bit
But its just great to see the Race Taxi coming in your mirror and overtake you at Spa

The track is 7 km long and soooo beautifull. Its like a small version in length of the Nurburgring, but a bigger version as far as the track width and corners are concerned.

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

[70Turbobug]

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

[Sandeep]

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

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:
