A set of full cuts would go nicely with those

I like the sound of the stage 1's because of my lack of funds. Until I can afford a turbo I think with towing hay when its over 100* this summer I will be wanting less heat. Its good to here your happy and I can't wait to here some others chime in with their experiences.

The rep from Pensacola diesel sent me an email saying they sent off some Bosch injectors to a company in Germany and they gut and rebuild stock injectors using Bosch's specs for power enhancments, well either way they are proven injectors if they "matched" Bosch and have been installing them in vehicles for years now without any backfires, that I've heard of.

I will be curious what turbo they will match with well... HTBG (58mm extended tip) with a 12cm housing?

 

I have to confirm this....Full cut is the same as laser cuts???

 

Just to let everyone know. I was doing some researching on the Pensacola stage 2 injectors, and they are just off the shelf Bosch Marine 300s.
They have the Marine spray pattern and are the wrong spray pattern for our trucks.
The marine spray pattern is 155*
The truck spray pattern is 145*.

Just thought I would let people know.

 

No they are not marine, they are B industrial with 4 hole 155*

 

I've heard that the wrong spray pattern is bad in the long run. If pensacola hasn't heard of any backfires in a number of years then I doubt that they are that bad of a spray pattern. Does anyone have confirmed damage from the wrong spray pattern? I've heard from a few people that the marine injectors are the same spray pattern as the ones in our trucks.

 

What do you think a marine injector is? Its still the wrong spray pattern.
There really isnt anything wrong with them. Its just going to be a little hotter and smokier. I ran marine 370s for almost 2 years and was very happy with the results. You just dont know how nice it it when you have the correct spray pattern
For example. I went from my marine 370s to DDP4$ and the EGTs were about the same only it takes longer for the DDPs to get there. The best part about the DDPs is there is no more idle haze when the truck is warm.
I have nothing against the marine injectors.

 

The injectors they are selling as stage 2 flow a just a bit less than the marine 370's. Run these with thin washers and about 16*, they are a very good bang for the buck.

 

They are just a Bosch 300 either way you look at it. You also run a marine injector at 16-16.5*.

 

Their injectors are on sale now for $205 SHIPPED to the house!!!!! My tax return is coming up soon!!!! Just thought you should all know so you can buy them and give us more reports on different trucks.

Just to hopefully help out a little.

Bowl in marine engines to the best of my knowledge is larger (diameter) than our trucks, the marine injector is made (wider spray pattern) for this larger bowl.
So if you advance the fuel delivery (timing) your injection takes place with the piston farther down (before top dead center BTC), where your spray pattern will spread farther.

If your run a injector with a wider spray angle on top of too much timing instead of spraying inside the bowl it hits the flat top of the piston, over time causing damage to piston and premature ring wear.

Hope this might help. If this was whats in question.

 

I have seen this mentioned over and over but no real proof of damage. I am just curious(as others seem to be too), if there is any real risk. I suspect there is not and this is more internet folk lore than anything. I am not even running them, but I am just curious if there is any proof anywhere.

 

I've only seen it in larger engines with misadjusted timing after pulling the cyl head.

But if the injection takes place way to far out of time or somethings wrong with and injector that causes the fuel to be sprayed out of the bowl it will cause damage to the pistons. At least with the ones I've seen its hard to believe its a coincidence, but I could be wrong, it just makes sence to me.

 

Thanks,
But I know the difference between our 5.9 and the marine version.

Good info for the rest of the members on here though.

 

I understand the theory behind it, and I am sure bad timing or failed injectors can cause damage. But, the injection even is so close to TDC that I have to wonder if all the fuel would infact make it into the bowl unless you are running very advanced timing. At 15* BTDC the piston is effectively already at the top of the bore, and the injector does protrude down as well. Now if you start running 20-25 the piston is down in the bore a tad.

Just trying to get my arms around this as it really does not make sense to me that the 10* pattern difference would cause a problem. Plus I have read as many people say the marines worked fine as I do people saying they won't. Seems the ones who say they won't have only read so....
