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

[kr3mn1 Van den BOSCH]

an AAT engine has 115 BHP not 150.

a mechanical pump is not a mechanical TDI pump. And what idiot goes and throws the wirings away to suspend the engine into a TD? or better, a monster betwen the SDI and TDI engines. I have 4 of those engines and nobody in europe is nuts enough to de-TDI the engine. With the right calipers , injectors and turbo it is possible to achieve a constant 250BHP power. with elektronics and stuff, not with a TD pump. sick.

and the AEL engine has 140BHP, not 150. and it differs from the AAT engine a lot.

Talk about ignorance!!! :shock:  You have a lot to learn, or unlearn as the case may be. :roll:

I think that's great you are able to achieve those HP numbers.  Could you please give us some details about how you got them?  What settings have you used?
What kind of turbo and at what boost level?
Have you changed nozzles? Please go into detail.
There are quite a few people on this forum who will be able to understand a quite technical explanation.  We are all interested in increasing HP.
Learning is always a two way street.  I think you will also find that on this two way street, we have all sort of agreed to be civil.  This is not like other forums.  Attacks and flames are not well accepted here.  
Perhaps you could express yourself in a way that is not so confrontational.
I think you will find the discussion will be much more benificial for everyone involved.

doesn't matter what the stock TDI numbers are.   it has a Giles pump and will produce how much power Giles has set it up for.  there won't be the tune-ability of an electronic TDI thats for sure, but without all the hassles of electronics, that is a price some are willing to pay.

so you're saying the mechanical TDI pumps of the early 90's are actually non TDI pumps? strange, as they don't have pre-chambers, and the injector injects directly into the cylinder... thus it must be direct injection???

He must be jealous that 1.6's are making almost as much hp. :lol:  :lol:  :lol:  :lol:

mechanical tdi pump on the early '90 ?? on this 5cyl engine there is no mechanical pump , the 1t engine ( first tdi engine from audi -vw ) run in 89-90 on the audi 100 tdi typ44 with electronic control.

and may be i'm crazy but i live in europe and i do mechanical convertion on this engine too !
i do it on a t4 vw bus just because part for this car is heavy to found !

I was talking about mechanical TDI pumps of the early '90's.   i wasn't specifically talking about a 5 cylinder TDI pump  :wink:

lol correction... 935racer is already pushing well beyond with his monster 1.6TD  :twisted:

A Bosch VE pump electronic or mechanical controlled, both are a mechanical unit with exactly the same pieces, but mechanical controlled pump offer an easy to tune and more potential with proper pieces.

There are a lot of mechanical TDI pump and some electronic IDI pump, It's just the manufacturer wich decide to use one or the other, or use zexel, or lucas...... etc......

Well, I prefer electric pump as I have a friend who is capable for adjusting it. My Transporter 2.5TDI has now about 350hp, 700Nm and next step is to get over 400hp, 800Nm out of it. To get big power out of any diesel (IDI, TDI, mechanical, electrical) is easy. To get wide powerband for everyday use is not. This is not that critical when you use these engines on a car that weights less than 1000kg, but try that on 2000kg van. And that's just when it is empty and has no trailer attached to it. I also drive my van something like 20 000km every year.

I have always concentrated on driveability and thus suffered some top power, but that's just me. Luckily enough I have a friend that is not copying others programs for TDI, but he invents something new all the time for them. He also made an electrical controlling for my VNT which had a huge difference at highway speeds (earlier >1,5bar, now 0,4-0,6 bar).

Don't get me wrong. Mechanical pumps are cool too and Mynäpump here makes pump mods for MB 3.0L IDI engines. They are getting over 700hp out of those without e-pump, but they are encountering some difficulties with rough idle and low rev area. First e-pump with Mynä mods has been just programmed and it was easy to do as old Bosch is very simple compared to modern ones. My programmer made also an electronic control for VNT on one of those MB's, but down side is cost (about 2000e with hardware and software). You can't do this with MegaSquirt.
