So is that pump/shaft etc. strong enough to handle DI pressures. I have been kindof thinking about using a stock VW TDI marine pump, but I have yet to locate one.

The pump came from a TDI engine. In europe they used mechanical pumps on tdi cars and trucks in the early going.

TDI Marine pumps are very expensive, and very hard to come by. From what I've been able to find out about them as well they are nothing really more than the same pump that was run on the late IDI 1.9AAZ motor, turned full tilt...

scopefrfd :Congrats on your mechanical TDI! I'm working on mine now and I'm glad to say that my pump choice having been able to have a friend test it is going to BE AWESOME

I drive a VW Caddy 1 with a mechanical pump (12mm). I use the intercooler from a Mercedes Sprinter and special nozzles (Frattelli 0,260mm). Specs.208hp and 480nm. The brakes i use are 312mm. (Audi TT)

Those are very impressive numbers, Jos. Can you tell us more info about your Caddy and show us some pics? Where are you located?

I am located in Holland and it takes my 4 years to get those specs out of this engine.

Holy cow! :lol:

A caddy bed grafted onto a Jetta...how trick is that!? :wink:

Jos, are the engine internals stock? Are you still running a K24 , or is the 208 hp with the new roller bearing turbo?

Please tell us more.

Very cool!

jos_br · « **Reply #23 on:** October 07, 2005, 11:38:16 am »

The car is build out of two cars,a Jetta and a caddy so the car is 22cm longer than usual. The engine was running with the k24 208hp and is now running with a adjusted rollerbearing turbo but the outlet is not good, so it must be adjusted agian.

208 hp on a K24...very cool!

Are the engine internals (pistons, rods, etc) stock or stronger aftermarket pieces?

jos_br · « **Reply #25 on:** October 07, 2005, 02:17:43 pm »

The onley things i've changed is a lowered compression and i have used other bearings (not piston). The k24 was also adjusted (stronger bearing) but not good enough, i have "used" four of them............

MMM.... that looks nice. Most impressed with the bodywork that was done. To the unknowing, probably even "knowledgeable" VW eye I doubt you could tell the differences in the length, etc. At least from the pics I see... Very nice job Jos.

Wow, beautiful Caddy!

Really nice numbers too.

Do you by chance have a dyno plot? If not, do you know roughly what RPM peak hp is? There is not a lot of people out there with hopped-up mechanical TDI's like yours so I'd like to know what the power curves are like. Thanks and great work!

From another site, it's my car.

Also some dyno plots from another car we have tuned. I'm not satisfied with the turbo and i will try to make some adjusments to the feulpump.
