Ok guys. I think that my next fuel upgrade after I get a tranny in is going to be delivery valves. I know already that i should be shot by the diesel gods because i don't have guages yet but those are coming in the next couple weeks. Anyway, on to my question. What kind of difference in egt's would i see between 191s a laser cuts. I've also heard about some called 022s. I really don't know what those are. And which of these DVs will support 550-600 HP in the future? I know this is a bit of an open ended question but i'm just looking for ideas really...

I would go with the laser cuts if you're looking for 550+ HP. They're close to the same price as 191's and 022's and throw more fuel. With the right injector, the 022's and laser cuts will flow enough fuel for your HP goals.

I think you better add the gauges -build your trans before you blow it apart then add more air and only then some more fuel according to your sig.

Do you have a bigger turbo? Laser Cuts and 191s wont do you any good without a bigger turbo. Laser Cuts will acutally put out enough fuel to put out the fire. How about injectors? If you get the right set of injectors and a turbo, 550-600 is pretty easy. There has been a few people that have made 800+ hp on stock 181s.

Actually, when I had my 12v I did the laser cut DV before injectors and it made a world of difference. Go with laser cuts but WATCH EGT'S! It's nothing you won't be able to control though.

I said the next FUEL upgrade. I know I'm gonna need a much larger turbo and i'm not planning to do anything else power wise till i get a tranny. Its about to blow up with just the 100 plate, and its not even full forward. The guages will be here soon and installed as soon as i can get the time to hook them up. I try not to get to heavy of a foot now because of the fact i don't have guages and that my TC is slipping like it was hot butter. But once i get the guages and the tranny, the power's gonna start flowing just as fast as i can get the money. Its been very hard not to do any more mods but i'm getting by.

Just go with 181 DV's

if they are stock on ur truck leave em, They flow plenty of fuel, injectors are what id do next if i was you... after the transmission 370s and 181 flow alot of fuel and lets be honest for a cheap upgrade, 370s are an awesome bang for the buck....

IF you insist on DV's tho, go with the full cuts and back off the plate and starwheel...

Do yourself a favor and get a governor spring kit first. So many people wait so long to do this easy, cheap, simple mod that makes so much difference in the driveability.

So why are injectors the better first step in more fuel than DV's? If they both increase fuel in, what am missing? Especially when a set of 370's are roughly the same price. You might be paying twice as much for a cleaner set of DDP's? Do they affect drive ability at all, other than possibly too much fuel?

TxDiesel007

EGTS being the main reason

After reading on here, and running both DV's, stock and 191s with my truck with twins, i have come to realize that the DV's just produce more heat, yes they can deliver more fuel to the injectors, but with lets suppose, 370s like im runnin, and the improper spray pattern, well, some of it goes to waste, WIth the proper spray pattern, holes and edm pattern, more of your fuel gets atomized, egts are reduced, smoke is reduced and controllable, thus with more atomization, u get more power, hence why the injectors are a better step up than DV's

Heck if Jim fulmer has made 750 plus rwhp with 181 DV's. why would one want laser cuts? Ill admit, i want a set just to see what the hype is, but before i even do those ill slap in my DDP 4's when i save up the coin to do so....

The 215's have the proper spray pattern, no? So wouldn't the DV's be a better application with a set of 215's as opposed to stock DV's with 370's? Retain the proper spray pattern, and still push more fuel. Just trying to understand, as I'll be in this boat soon enough, but conversion injectors aren't cheap, and I'd like to buy them just once.

I don't know who it was, I think maybe signature600??? Anyway someone made about 10HP more with laser cuts and stock injectors than 181's and 370's on some dyno runs. I am contemplating the idea of adding some laser cuts soon...

TxDiesel007

Yessir they do

215s that is.. Do not get discouraged tho on the bigger injectors, If you want some proper spray pattern injectors for a bit less money, u can always go new era 370s, A much better improvement over stock 370s

IIRC Teddy Bear on here is running them and he says they are pretty good...

Well, I'm doing a conversion onto my ISB, I was just trying to figure it out with what I know about 12v engines.

RonA has done a p-pump on a 24v, and laid down some very impressive numbers. Around 500 with M1.2 injectors, close to 600 (don't remember the exact number) with M4's, and 680ish with M7's. All on 181 DV's, but he bumped the timing on latter runs (not sure if he swapped primary turbos or not). Those sticks are all in the $800-$1000 range. I'd be curious to know what a set of 191, half cut or full cut DV"s would get him. Especially at roughly 1/3rd the cost. Almost seems too good to be true.
