Default Re: Fuel Injectors / Rail

DOES THIS MAKE SENSE TO ANYONE ?

As mentioned earlier in this thread, I decided to send my injectors off for flow testing and matching to the "INJECTOR GURU" in Indianapolis... When I pulled them I noted the product numbers, both the MB part # A1120780149 and the Bosch part # 0-280-156-014 and researched the specs from Stan Weiss... His extensive list noted zero information except for the fact that these injectors were spec'd out for the MB 2.6L engine... I immediately thought it was a typo and called Bosch directly who said that they could not give me the specs on this injector because the information was proprietary to MB... That made me really happy...

Needless to say, I did an impedance reading and came-up with 15 ohms on all the injectors, then sent them to Doug for testing... Well, Doug called me today and said he has not flow tested the injectors yet but wanted to let me know that the injectors I sent him are the injectors that are spec'd out for the C240 2.6L MB engine, not the 3.2L MB engine which are Bosch part number 0-280-156-072 and he was confused... I got confused as well...

Then he told me that the 3.2L injectors have a flow rate of about 37 lbs and the 2.6L injectors have a flow rate of about 26 lbs... Then we began a discussion about this while I pulled-up Stan Weiss' injector tables on my computer... Low and behold !!!

We have not yet determined exactly why there are smaller injectors in this car, but we speculated that the Crossfire was fitted with lower flow injectors to increase fuel economy numbers.

That being said, I would like to ask both HUGO in Australia and WOODY in England if they would pull their injectors to get the Bosch part number and compare them... Perhaps we can get to the bottom of this and may find a cheap way to increase HP by installing the higher flow injectors...
