Bosch 370 injectors

[CDegner]

OK, I know a couple people on here are running them, at least they were. If you are still running them, how about posting whether you still like them. I have read through all the old post and want a more current opinion. I'm looking at other options in my quest to get up to 300RWHP and no, I do do not want to run PODs in my truck.



What shop did you have make the body swap from 2nd gen to 1st and adjust the pop pressure? What did is set you back? I know the 370 injector flows a little less than the PODs. If you had it to do over again, would you still make the transition?



Just thinking to myself .

I'd wait a little while... I'm going to be testing a set of big larger-than-pod EDM's from Don M here pretty soon.



Maybe if they work well, they'll hit the market and they would work better than 370's.

 

[CDegner]

Who ever said they were going to use 370s? I am only asking about the 370 injector because I know a couple people on here have used them.



I do look forward to hearing how your EDMs work though.

I'm still running the 370 converted to ve injectors on my truck.

Over time they seem to have gotten better with fueling and air enhancements. I like that I can get 20mpg driving conservative or get all over it and peg my 50lb gage. You couldn't prove that pods have more fuel or make more power by me because of the two sets we put into two other first gen trucks and cranked the fuel up in. but I'm not here to start a war over injectors

Over all I think they are a great injector although I got a little better mileage with 185s ( I wish I still had that set)



The pop off pressure was set at 3400lbs and I believe this is the secret to making more power IMHO than pods.



Bradley's diesel injection service in Klamath Falls OR.

Built this set for me to my specs twice. I paid both times + the cost of the 370s. You could probably save $200 with the pods and save yourself the headache/ satisfaction of building a morphadite set of injectors especialy if you found the pods on sale.

Stupid thought, but IF PODs flowed more than 370s, wouldn't the 2nd gen guys buy PODs and and put the tips in their bodies?

It would appear, at least on the surface, that this would be a good "morph" injector combo for a 2nd gen.



OK... helmut on, ready for the barrage.

POD's are more bread than 370's.



Since the 370's are designed for marine pistons... their spray pattern isn't optimized for our pistons.



370's still make good power in our engines... only because the nozzles flow more than OEM.



The next logical step after 370's that most 2nd-Gen 12-valve owners use is either a set of extrude honed nozzles or a set of EDM'd nozzles.

a set of EDM'd nozzles.



So far like EDM's, dyno testing will tell the tale.

Why pay more for then injector AND have to pay to have the pop pressure adjusted up? Plust there is still the issue of the nozzle design that causes fuel "dribble"?

Plus the design of the 370's is superior.



I'm all for EDM's... they're the wave of the future IMO.

I'l second the EDMs. They are better than stock, and even with the same flow as stock (mine were custom- MACH1s too hot for my set up), they make more power (which I need to cut back on using regularly ). Havent been on a straight hwy trip, but intown MPGs seem up 1-1. 5. I'd guess the hwy MPGs to be up 2 or so. I'm going to put in some thicker washers and see if that has any effect on smoke, EGTs, etc, or if I just need to cowboy up and get the pump redone. When i have them out, I'll get them pop tested and see where that is. Then I'll know if I need to advance, retard, or leave the timing.



I think I remember the PODs making +20hp over 370 daimond B tips, all else being equal. I dont like the idea of dribbling fuel, either, esp at $1. 60+ per gallon. BUrn it ALL and cleanly.

Well my set of 370's were the first set of injectors from Bradley's Diesel Injection Service in Klamath Falls, OR that they built for a first gen. After installing them they worked quite well, but I was still searching for more power so I took them back out and extrude honed them to a stage three and they put out some fuel. I took my 60 over stock and put them under a microscope and compared them to my 370's and there was a big difference it looked like a rat could walk through the holes on the tips. If you want more info Bradley's number is 1-(541) 882-5031 and talk to either Joe or Carl they will know what you are talking about if you ask them about a set of 370's for a first gen. They have a 800 number, but I don't have it handy i'll try to will post it later. They are a very good shop and don't have a problem answering questions. Since Carl and Joe are good friends of mine I got everything for cost so I couldn't tell you what it would cost for a set. I talked to Carl not to long ago and he is looking into another injector to experiment with. I should call him to see what he has found out. Oh yeah did I mention that I like my 370's they do the job just fine, but I am all-ways looking for more power... ... ... ... ... ...

Maybe you guys should go with a modified Mack 8 hole injector. Then send those to Extrude Hone for a Stage 3 job. Then may be you will have the injector you guys think you need,For the most of you who have at best 375cc of fuel pushing from the VE. (Some are above that but not many)

 

[Stomp]

Hey Antrim93 you have a part number i'm allways willing to try new things.

Yeah, you go try those and send me your old extrude honed 375's No? Not going t go for that? Why not?

I am currently looking into an 8 hole injector we will have to see what happens to my 370's?

[dpuckett]

My first set of EDMs were 8 holers- tiny holes, but they'd pour in the fuel.

How big are the Mack injector tips? I know many of them have Bosch pumps.

I dont know of anyone flowing 375mm/stroke out of a VE. That would be about 800hp, if fuel flow vs hp is linear (160hp out of 74mm). But i dont think it is, is it? I could be wrong, though. There are just too many other variables at the level to know for sure.

 

[BushWakr - RIP]

I think he means 375cc per thousand strokes.

Having said that it may be possible to have that much delivered, but at this point I think that the stock VE pushes roughly 200cc/mil

during start condition only. Almost immedidately after the starter begins to rotate the crank, that fueling level drops back to "idle value". This process is why you see that initial "puff" of black on startup.

I was just trying to stir things up. Ive seen many 2nd gen P-pumped trucks put out some great #'s with 370's. I also belive there is a 410 marine but don't remeber. The one thing about the 8 hole is that the tips can get weak. Currently looking into different injectors myself,B. D. XXX 60 hp. for sale. They are a marine application. Looked up info on them only got cpl #'s of marine engines but could'nt find HP of them. Also have hole size and other specs. I may one day go with Buddha injectors... ...

 

[R.E. Miller]

Good info, I am tired of having people think my truck is blown up when it is cold out, or it isn't warmed up. I have been in contemplation over this for quite some time. I would like to know more about the EDM's, where can I find it? Or should I just have the switch-a-roo with the 370's and be happy? If I did not have to drive my truck every day, I would not mind the bluish haze when cold too much.

Thanks,

Russell
