Audi 5-Cyl TDI (AAT) From Europe with a Giles Mech TDI Pump!

[BejamminR]

I think you guys will all like this. Here we have an imported European Audi 2.5L 5-cylinder TDI (Engine code AAT). We have eschewed electronic control and outfitted a Giles mechanical fuel pump. In this video, we're just firing up the engine for its final test run before sending it home with the customer. I'm bracing the engine, because it's suspended from a hoist - Giles is firing it up.   Crazy? Maybe. But look at how smoothly and quietly that baby runs... Oh yes.

If you guys have any questions, ask away! We have some more pictures of the engine and pump while still in progress, which should be posted on the Performance Diesel Injection website once it is live. I'm presently working on that with Giles, and we're hopeful that the site will be fully operational before the start of 2008.  We'll be sure to keep everyone posted! :wink:

whats that powerhouse going into?

[BejamminR]

Originally, it was intended for a 1994 Audi A6 C100 Quattro. So at stock, it was 114bhp (~85kW). With everything fully modded, it should be something in the range of 150+HP, intercooled, with a Giles performance pump, and 4-wheel drive. We believe that the customer has changed his mind and will now be putting it into a new VW Camper van which looks like the Transporter but has a full extended roof and everything. It was never sold here as far as I know, (I'm wrong, it WAS sold here) and was brought in from California. It was a VR6 gas engine, and is being converted to take this monster instead.

Who knows, maybe he'll change his mind yet again and put it into the car. I know I'd love to see it in any of the vehicles. More pictures will follow once the conversion is either well under way or complete.

(Edited for accuracy and to protect the innocent.)

WOW!!!! very nice   , I would love to get my hands on one of those motors.....

[Slave2School]

It sounds so smooth and silky, has any other engine work been done?

[BejamminR]

The timing reference marks were somehow all wrong, so we manually timed it and put new reference marks on. Other than that, we're leaving the engine work to the customer.

Very nice engine! and vid!!!
Would have been quite the oh' $%(^ moment if on that first crank and SNAP...engine on the floor
Very nice sounding though!

i can't wait to see this engine put into jason's vw camper van.

as far as i know he's bought it, and will be getting it delivered here in a short while.  i'm pretty sure it is a vw weekender.

he was looking to keep the transmission automatic for the wife, but i tried to convince him to go with stick  :lol:.  since it is automatic, he will need a new flywheel, tranny, clutch pedal, and shifter with linkage (cable shift is probably his best option)

jason wants to start importing these engines and converting them to mechanical here.  i'm all in for importing these and turning them around as there is enough demand.  apparently over in England they are plentiful and cheap!

Giles did an amazing job on this pump!

[BejamminR]

Yeah, sounds like Jay might be actually going across the pond to get the right parts for all of the conversions on that thing. Whichever way he goes, it's going to be a sweet unit. And yes, Giles did quite the job on this pump - there's a significant power increase at stock settings, and still lots of headroom for future increases.  :wink:

Nice!

If they get common well have to start referring to engines as mTDI-IV and m-TDI-V.

Nice!

Too true... on this board, at least the mTDI's get quite a bit of respect. TDIclub...alot harder to convince many of them, etc. I can tell you how many people I've had ask me about why I didn't go electronics and that its the only way to go... argh...

There is also the right and the wrong way to do it. Sounds like this is another "done right".

hopefully this will help convert the skeptical  or at least those with constant CEL's and vag-com issues...  :lol:

[RabbitGTDguy]

I really hope it will. Done right, as mentioned above with a properly worked pump there is room for alot more tuning and power just from a turn of the pump, a few adjustments, etc. I still have alot I can do on my pump...and lets not even go into the timing possibilities.
I prefer the simplicity (not that I couldn't handle the electronics) and think that it can make the same if not more power than an "e" car. Though, I don't have the dyno to prove that yet. Only a single wire, mechanically operated TDI that runs silky smooth too

Bejammin:

Kind of new around here, so I have to ask, who/what/where is Giles?

Reason I ask is that I have a 2.5 TDI sitting on the engine stand in my shop, and we are going to put it into my best pal's Westy Sycro (minty 1987).  Got most of what I need, but was thinking seriously of going mechanical instead of electronic control.  Sounds like you may be able to steer me to a good solution to this issue.

I have a 2.0 TD that is going into my 924 some day, and that is just the proof-of-concept to build one of my girls a 924S or 944 TDI, but the price of the 2.5 is sufficiently high to want to know the whole thing works as I hope before splashing the cash.  Again, going MTDI is preferred.

Pat:
Full Disclosure: I work for Giles, so feel free to question or challenge my assertions. I'm a pretty honest guy and I'm not saying anything that's untrue, but I think it's important to make affiliations well known.

Giles is a 20-year veteran of the diesel fuel injection industry. He has spent the past 20 years (up until 2nd quarter of this year) working at someone else's shop, in which he spent the majority of that time running it for the actual owner. As of the 2nd quarter of this year, he is operating his own shop - Performance Diesel Injection in Markham.

Giles' main claim to fame is a number of modifications that he can and does do to a variety of mechanically-controlled diesel fuel injection pumps and some electronically-controlled ones as well. His specialty niche is the series of pumps which are used in VW / Audi group IDI diesels, and/or the mechanical conversions for VW / Audi group TDI's. While I'm not really allowed to talk about specifically what he does (also, I don't know all of the things he does), his modifications are all custom, in some cases involving job-specific parts fabrication or modification from stock, rather than simple installs and "mix-and-match" of readily-available commercial components. So rather than just slapping together components from other pumps, or commerically available parts for "performance" purposes, Giles heavily modifies the pump internals to support not just increased fuelling, but increased efficiency - fuelling within appropriate parameters for the engine such that you aren't limited to the compromise of increased power equalling proportionately increased black smoke, and when you're not using the full force of your new power, your mileage is increased significantly.

So basically, Giles owns and operates a company called Performance Diesel Injection in Markham, Ontario. He makes a mean performance diesel fuel pump and specializes in the pumps for our vehicles, as well as doing rebuilds, testing, calibration, etc. of virtually any diesel fuel pump you like. He has something of a reputation on these forums, because many people know and like his pumps, and others wish that he'd tell exactly what he does to them. Since these mods are classified as trade secrets (he really did spend a pile of time, money, and effort on the R & D to learn them) he keeps it pretty quiet. Can't argue with results, though. Hopefully before too long we should be able to provide some clear-cut numbers as well.

Hope all of that provides an answer.

As far as the M-TDI pump and stuff, feel free to either ask around to folks on this board, or give Giles a call at Performance Diesel Injection in Markham.
