Bosch 190 injectors

[rdodd]

Besides the price, what is the difference between the bosch 185 (powerwagons) and the bosch 190 injectors? Do the 190,s deliver a little more power? I can,t believe the price they want for 185,s now, I think i paid under $300 for mine when i bought them several years ago from Tim at City Diesel.

I got my 185's in one of the group buys that happened about 5 years ago. The price was something like $ 235 plus shipping. They have been good injectors.

Are the bosch 190,s about the same injector in terms of power?

I don't know how much more power they make than 185s but I spoke to one of the diesel shops that sell them a while back. The guy said they do smoke a bit more than 185s. . I think you could controll your smoke by a few pump adjustments in your diaphram,cone and full fuel settings and still realise much better power than the stockers, especially if your stock ones are worn and dirty... ... . Oops I just read that you already have 185s... Hmmm I'm not sure . i would figure the next step up would be something more aggressive than the 190s... .

i got my 190's from piers and i was told they give you 28 rwhp..... they work great in my truck... . the only thing is i now have more diesel smell from the exhaust...

How bout a set of POD's? Cheap they are. Smoke can be controlled with the right foot and pump settings.

I am getting ready to put a set of 190's in, as the pod's at high altitude smoke way to much with my 1200 # camper me and the dogs. Smog nazi's have sent me 2 notices in the mail saying somebody called in and complained, oops!!! It's weird no matter how much lead I mill out of my right foot i just can't keep the smoke under control. Also as spring and with it warmer temps the problem is only going to get worse. Anyone running 190's at high elevation??? Please let me know how they run for you. thanks ahead.

We did a comparison of the "185's" and the 190's on our dyno using a 93 test mule.

The label of the 190's is more a description of the HP difference between the two injectors... . as I recall we ran 5-7 RWHP more with the 190's, as opposed to the 185's.



Also, this sometimes gets lost in the journey toward more HP and more fun... . the Lucas/POD injector has as different tip design than the other injectors. It is "large sac" type injector.

Basically this results in the injector releasing it's fuel charge and closing off like a normal nozzle BUT... the tip design retains a minute amount of fuel in the "sac" and that last bit is not under as much pressure... this results in a dribble or poor atomization which in turn results in the haze that they are commonly know for.

The POD also flows a bit more fuel than the 2nd gen 370 performance injectors when both are compared in "stock/factory condtion".



You might think that if you raise the pop pressure on the POD that it would help compensate for the haze issue. Well, I had a set of POD's retested, flowed/reset to 270 bar... .

I regret that I did not see any amount of improvement in the haze/smoke condition at idle/low boost fueling.

There is, I believe, a down side to that experiment... If you have an "experienced" pump (read: original) it will place a fair bit more strain on that pump, particularly when you raise the timing to help compensate for the higher pop pressure which retards timing.

I would not suggest doing this (raising bar values) over 255-260 bar unless you are running a fresh VE in your truck... mind you, that's only my opinion and I did NOT do any dyno testing to see if there were other measureable results from this.
