Are marine 370s better?

[JLuechauer]

hello fellow cummins lovers. I am excited to be a new member and with my first question. Do the rebuilt 370 marine injectors make power than the PODS?

Jevon, welcome to the TDR. What year of truck are you wanting to know about? If you setup your signature, find user control panel then edit signature, we will know what you have. From what I understand the PODS flow more fuel than the 370's, somewhere I read the pods are 390's?? Just the two injectors are different where the fuel lines attach so one would have to modify the 370's to fit a 1st gen VE powered engine and modify the pods to fit the fuel lines on a P pumped 2nd gen engine. From what I've read the pod's modified don't do as well as 370's in p-pumped version.

I did know that there were modifications needed to get 370s in a 1st gen truck but i did not know if there was a benifit to using them. thanks for the info. I also think I got my signature straight

JLuechauer, Welcome to the ranch bud... . ask any question you need to have info on and the guys will all be willing to help out.

In general, the Lucas (POD's) run more fuel than 370's when both sets are in new/stock condition... if either are modified then that will change of course.

First you should decide what you are aiming for...

If you want to go wild, then you would likely want to look at a modified version of POD's or 370's... perhaps extrude honed as an example...

If that is the goal then you need to be prepared to add some significant modifications to your air system, both turbo/exhaust housing, air filter system and, exhaust system.

As you go up in aggressiveness the other issue become more and more important.

Set a goal for your truck then you will have a much easier time choosing what mods you need to accomplish that goal.

I also understand, or at least have been lead to believe that there is a difference in the spray patterns and angles of the PODs and 370s based on the piston design they were intended to feed.

That could account for why the PODs run better in the first gen engines, and why the 370s run better in the 2ng gens.

Anybody?

Hijack for a sec. What would be a better injector to send off to be extruded honed, a set of stockers such as my 9mm tipped non-IC'd or a set of POD'S? Does it make a difference? High dollar? ... .

Bill,

I would NOT send a set of 9 mm non I/C injectors to get extrude honed.

The reason is that they will ONLY be good to use in an old head. If you ever have to replace the head you will get a modern one that will take 7 mm injectors... .

And who will buy the used ones if/when you need to sell them?

Send a set of 7 mm modern sized injectors to get honed... . they are more versatile.

That's why I "experimented" with my stock 9 mm injectors... . they are pretty useless anyway.

Ok but does it matter whether you are sending a set of PODS or set of 7mm stockers? Is it like, you're gonna end up with a extrude honed tip that flows X amount of fuel and sprays at X angle? If they both will be equal when its all said and done, to me it would be more benificial to send off a set of stockers, keep/sell the PODS, which are worth more in new/original/used condition. Is this correct?

PODS or set of 7mm stockers

That's a question that is probably best answered by the guys who do the honing.

IF I were sending a set off to be extrude honed (and I am considering it), I would send off a set of stocker or 185/190 injectors. That is based off a couple reasons.



1) # holes/spray pattern. The stock and 185/190 injectors have more holes in the nozzle. This is going to lead to better atomization than the 4 holes in PODs.



2) Injector design. The PODs (as well as 370s) are a sac design. That means there is a little residual pocket that holds fuel in the tip of the nozzle. This is partially to blame for the smokiness of the PODs. The 185/190s are a seat-hold nozzle design. The tip of the damping cone fits all the way down into the nozzle body seat. This leaves no extra fuel to "dribble" into the cylinder.



Just my $0. 02 worth.

[JLuechauer]

thanks for your help guys. I did not even know that POD injectors could be modified even more.

 

[BushWakr - RIP]

I agree with Carl's explanation... the better choice for honing would be the non POD injector.

The only limitation will then become how big/large can they be opened up before they experience weakening of the tip. A good quality shop can do that just right for you... the last thing you need is a tip failure while in service.

Bob, how do we go about sending off a set of injectors for extrude honing? This comparable to price of the PODS new or much more?
