I want to put injectors and delivery valves on. but want to know if they effect fuel economy, or is that only determined by my lead foot? also what is the best D.V. for towing? I want some 40 horse injectors.

 

the best towing dv's will probably be what u have right now, the 181's. They should be able to support some big injectors, so if I were u I would just get injectors and leave the dv's alone. Some injectors increase milage, but depends how big u wanna go, and what brand. And of course ur right foot always controls it alot.

 

I agree with box5.You already have the 215 pump with 181 DV.Its us guys with the 160 and 175 pumps that have to mod the DV.Will be borrowing a set of LC is weekend and will be expermenting with them,including moving the plate,adjusting star srew,smoke srew and boost.

 

Posting to watch .

 

Which 40 horse are you thinking of going with?? ddp, bosch 300's, pensacola diesel stage 1??

 

I too am looking at injectors for a moderate HP boost. I tow A LOT. and do a far bit of daily commuting via gravel roads and county hiways. I was thinking some from Pensacola, they are new, no core charge, and are very reasonable in price. I'll keep watching this thread for more input.

 

Hearing that they are 4 hole injectors makes me wonder if they will do good towing. I agree they are cheap and seem to be a fair injector for the price but I haven't seen anyone that has them and tows also.

A set of 215 injectors will give you more power and work for towing. Your mileage isn't likely to improve with any injectors however if you don't change anything else. An alternative that will cost you way less money is to increase your timing to 15.5 to 16 degrees btdc. Stock it is somewhere around 13.5. A more expensive way to increase mileage is a PDR cam. Mine paid for itself in 58k miles.

 

actually my pump is a 180 so do I still have the 181 D.V.'s? the injectors I want are made from stock with a E.D.M. so there is a core. we put these on my friends truck and it made a huge difference. and they are priced at $40.00 each. no shipping charge because my friends heavy equipment repair shop gets all there injection work done there

 

You will still have 181 DV's in the 180 pump. How much is the core charge? My DDP's were $25 a stick for core, I just hung on to the old ones incase I need a back up set sometime.

 

ddp stage 1s are a 50hp injector and will give you 1-4mpg but there 500 but they are nice injector for fuel mileage and a little gain.

 

Ive got pensacola stage 2s n ive gained more mpg and they flow plenty of fuel even through the stock Dvs so im sure the stage ones wont be aproblem with the stock dvs ... towing tho well i havent towed anything thing with these yet so i wouldnt know
