I don't believe anyone accused you of anything...more questions your claims.
There is alot more that goes into "pump design and performance" than just swapping a camplate/plunger/hydraulic head when your using the IDI pumps as a base...
Bosch did do a great job at keeping their pumps inner workings a fairly good secret and to this day, in MOST...not all BOSCH shops, most will not tweak a pump beyond its factory settings as specified by bosch.
However, there are many considerations to address when looking at the IDI engine vs. the DI engines (here talking specifically about the TDI). Fuel pressure, timing advance and camplate profile are only a few.
What are your considerations in building your mTDI pumps when it comes to timing advance? Its an important consideration...
What about full load fueling vs. relative and max RPM's? Are you aware of the operation and travel of the gov./throttle mechnism on a true mechanical direct injection pump vs. a indirect injection pump?
True bench testing will show you this...in the hard numbers. Actual testing on a car (as many of us can't afford the test equipment) provides a realistic sense of differences when you know "how" a mechanically controlled, direct injection diesel engine should sound like, smoke like and operate like as well.
I'm not going to beat the dead horse here...but sure, you are able to "suceed" in "running" an mTDI with a simply modified IDI injection pump (by swapping the hydraulic head, plunger, camplate for a TDI unit), but is it going to perform at its best potential? No, not without further modification to areas that those of us that spend their lives rebuilding/modifying pumps for a living (i.e. Giles) or those of us that have been down the mTDI road before, know what these engines are looking for specifically internally (not just fuel considerations) have discovered. The pump you build will run the engine...but not optimally...plain and simple. I'd put mine, a Tin-Tin or a Giles pump up against that anyday. I'd be interested in seeing the smoking habits, sound of the motor under load and how it would handle "further" fueling...if it isn't already maxed out.
However, if your customers are happy....then they don't know the less and with the number of mTDI's popping up quite frequently now, I wouldn't be suprised. Simply put, in the configuration that you have thus far mentioned....maybe stock power is achieveable. Thats a big maybe. Is the pump properly balanced and tuned for the motor though? I would doubt it, but would enjoy being proven wrong. Again, to some though this really may not matter. To many on the boards here though, I think they'd take this into carefull consideration. If your happy with a ton of smoke, not enough advance, etc. by all means. Run the route. However, optimal performance and economy will never be obtained.
my .02....again.
Prothe, on seperate occasions I've actual bought a product from you and inquired about other bits (on ebay). Namely, the source country for your hydraulic heads, and "performance" nozzles, etc. On a few different occasions, and I never received a response. I'm not going to say that may it was just a missed inquiry, etc. given the volume of inquires that you may have...but its just that. It didn't make me settled in your product though and I could draw my own conclusions, but chose the route of more expense...especially given the track record of some aftermarket junk that has been sold elsewhere. In the end, I really am a firm believer that you get what you pay for. I learned that with the timing kit I got....though, the cam lock plate still comes in handy!
This isn't a flame and please do not take it that way...as with many diesel goods on the market one can argue how they are installed, condition, expertise, etc. among a variety of other things and you certainly aren't the only one that sells these goods. Many have had "good" experiences if you want to call them that...no ill effects, everything works, ok, etc. but again....you get what you paid for.
