I'm going through my options. The cheapest means of getting my boost up (I'm only hitting 20-22psi after all my work) is to simply install a 1/8 NPT plug on the compressor side of the turbo. Anyone else doing this?

If plugging the wastegate is a viable option, I've got a better idea than the boost elbow or plug. A "controllable" plug if you will. I could also refine it a little bit with a "safety" now that I think about it.

Guess I just need to know if plugging the wastegate line is a good idea.

I'd like to be able to have a switchable mode of stock wastegating and a full on mode for the turbo.

I realize they make turbo boost controllers, but in this instance we really don't need anything that advanced I believe.

well i don't have much experience but from what i remember back in my class at wyotech that plugging the wastegate isn't too great of an idea because that will cause the turbo to overspin..........if i'm wrong i apologizeopcorn:opcorn: of course tho i do plan on spending the money for an adjustable boost elbow for my 01:lol3:

When I bought my Edge Comp box it came with a boost elbow. Contact a dealer or even Edge direct, maybe they will send you one for free. My HX35 with the factory injectors and my Comp on 5x5 would put out a max of 35lbs and 30lbs consistently. Add a set of nozzles and hold on to wallet:$::$:, Head gasket time!! 40-45lbs of boost!!

 

[DIESELGUY84]

Plugging the wastegate isn't a good idea, Get and adjustable boost elbow, they're about $20 new.

 

[BCCC]

how much are head gaskets??

 

[Chris Mallett]

how much are head gaskets??

$225.00+ depending on what else is done at the same time...I don't think you can pull the head for less than $350.00:$::$::$:

 

[plig_kid]

A head gasket from cummins is 65 bucks. thats cost anyway. Im putting mine together right now 225 for a fire ring gasket, 380 for studs, 200 to get it cut, and some free labor, Maybe boost boots from BD if I feel ambitious! And the Big sticks back in 'er!

Hear me out...

I'm thinking of an idea. Use a pressure switch set to say 30psi to open or close a solenoid. That way you have a safety for it. You could also wire in an "override" to keep the solenoid open for stock metering. I'd assume keeping it stock would allow people to roll the coal when they want to. Or does having the boost elbow not make that much of a difference?

my waste gates been shut for ten years on my truck with stock turbo and big sticks and an edge drag box. No problem also sees about 52lbs when you roll on it and hold just over 40psi. never missed a beat. also i havre a stock head gasket no studs nada. this is a cummins not a power joke boost it. Never said no to me seems to love it also ive never hurt the turbo. I drive it nice until i have to get er done. Truck runs fine and pulls hard everytime. And ive got the ''53'' block what a joke people get scared of the 53 bolck i love mine.

 

[countrycummins99]

i agree with boosted 99.5 and i also have the 53 block and i run my edge on 5x5 religiously when i need the power no problems here

In the 10 years you've had it, didn't you only rack up like 50K? I thought I saw you post that...

I've got a 53 block. I love the coolant pissing it does out the crack...

So, what's you're goal? Smoke on demand? or better performance? Both?
A while back I priced Hobbs brand pressure switches, they were $30 apiece, but the kicker was you had to buy a box of 30 switches, have you found them cheaper?

 

[patracy]

Both basically.

I believe I've got a source fro pressure switches.

 

[Tofunk2drunk]

cant u put a boost controller in there??

my buddys goes from his wastegate to the turbo housing....bigger turbo running 65lbs of max boost on stock internals

 

[patracy]

You could, but electronic boost controllers are about $200 from what I've seen. Basically You want something that limits the pressure to the wastegate until say about 30psi, then allow it to open.

As to your buddy, he's not going to run 65psi on a stock internal engine for long...

 

[Boosted99.5]

16,000 miles to be exact but very hard ones needed a tranny at 960miles oops everyone said its a cummins it wont break but they never told me chrysler used their trannies go figure....

The compressor map for the HX35 maxes out at 37-38PSI and it will deliver in the 600's CFM. Any amount of boost over that is super heating your charge air and not increasing volume; 400 degrees plus. Running boost over the max is putting you on borrowed time with any turbo.

With a boost gauge, you can plug the waste gate and drive with the gauge and safely run it up to mid-30's. Long term, if you are looking for 350+ HP, you would be best served to get a turbo that can deliver that air at much cooler temps. Aurora 3000, S300, BD Super Single, etc. These all deliver around a 1000 or more CFM.

Boost doesn't make HP, air (by the cubic feet) and fuel make HP. The cooler the air the better.

wouldn't a manual boost controller ($50) work as well? i've always used mbc's on my turbo gas cars; and they do exactly what they're supposed to.

if the wg actuator is set to open on our hx35's at 22 psi or whatever it is, an mbc set to say, 32psi, would get us the extra air and all we'd need then is the fuel to make the power.
correct me if i'm wrong, i'm a turbo gas car guy, so diesel performance is new to me here!

Yep, a manual works fine. But my idea was to have a switchable setup. So you can have stock boost if you wanted smoke. Just kicking around ideas.

 

[terminaltsi]

there are mbc setups that allow different boost settings for traction limited fwd cars. look here: DEJON | Powerhouse go all the way to the bottom and look for the section "boost controllers" and then look at the 2 way setups. think that would work?
