Just dreaming here, but still may be a next project. Most 4BT's I see for sale have the rotary pump like a 1st gen VE pump. My question is, can you run 370's with a VE pump? Are the POD's going to be close if not?

POD's flow more than 370's, so you'll have all the fuel you need with them. On another note, I saw a 4bt on e-bay yesterday with an 'inline' pump, according to the description. I dunno if it's a baby p-pump, or what, but naturatlly, I wanted it...I've just acquired an old K-5 Blazer so I'm thinking 28mpg plow truck.

I saw those on ebay too, but that was only a couple inline pumps out of dozens of rotary ones I've seen. Thanks for the POD heads up!

I think a reasonably cranked-up VE 4bt with an hy-9 would be a great plowing engine, especially with an auto behind it. With the smaller size of the 4bt, you'd be working the engine, even plowing, so wet-stacking wouldn't be as much an issue as it may be with the 6bt.

That's my idea, cranked up, 370's or POD's, HX or HY35 with a 9 or 12 housing, and HTT stage 3 kit for the impeller side.

The 1st gen injectors are a little different.. you can move the internal parts from the second gens over to the first.. (I can't rememever off the top of my head what was different... I was thinking it was the return lines.)
You will want to stick with the hx35 turbo... it will be way too hot with the 9cm housing.. (And I haven't seen any upgrades listed for the hy turbo... )

This is interesting... I've got a 74' IH Scout II, and I have been thinking for years a cranked up 4BT would be really cool in it...... I was figuring on 370's but what the heck are POD's ?????

For the turbo, I was thinking HX30/9

We run a drag truck with a 320 hp 4bt in it.
You have to watch when you start jacking up the
pressure on the rotary pump.
You have to go to a 5 hole injector nozzle.
The marine 370 has 4 holes and builds to much
pressure in the pump.
Get's real ugly, real fast..
The inline is the way to go for big hp.
Got a bud has a 4b twin turbo making 500 hp.
Later 6bta...

Can you tell us how your bud got it up so high that like a 6 cylinder power cruve.

Actually that number was with a custom built HX60 turbo.
I dont know if he has a number with the twins yet..
You can check out his site at malloracing.com
He runs on the salt, we run on asphalt.
We run an 86 ford ranger with a very stout 4 bt.
12.4 @ 102 no nitrous or propane.
320hp and 550ftlb of torque and 4300rpm, and
all cummins parts.
We are a cummins dealer, phaseiidiesel.com
Anything I can help with let me know..
Later 6bta....

I'm a little confused at some of these comments.. I didn't think the 370 had 4 holes?? Higher pressure in the pump, the second gen injectors have a higher pop off pressure, never seen a problem when they are set closer to the VE specs.. I know you can run too high transfer pressure, and it will push the front seal out..
Inline may be making big HP.. but the VE's aren't doing too bad.. there are a few over 600.. (14mm plunger even 1*mm plungers ) custom injectors are the way to go for big HP...
HX 60 is a big charger.. many of the pullers (tractor) are running a custom 60 and having good luck with it.. and spooling it where they where having a hard time with a 50..
Good luck, sounds like a fun project....

The VE pump we run on the ranger is at its max.
Had the truck at the diesel nat's in N.J.
Blew the pump apart internally, take it off throw
it away. Almost nothing could be reused.
Pump guy said 4 hole tips, no good!
I'll try to get some more info on this and will let
you know.
As far as the HX60 he runs at bonniville on the salt
so he has like a mile to spool it up.
I like to think there is more to it than just custom injectors,
but I'm listening. 6bta...

So we're talking injector line backpressure, sort of? I know the guy who built my pump mentioned cranking the pump with stock injectors is especially hard on the pump.

6bta, where in NY are you?

I'm with JDGnut here, I always thought marine 370's where 5 hole nozzles.
The POD's that I and alot of 1st gen guys run is a 4 hole nozzle, but there are 4 big holes. I know that is shoots alot more fuel than the stock 6 hole nozzle.
