I never thought about the fuel pressure doing that but it might be possible. But if I were to do a setup like that I would just tune it for good power and make it run as well as possible. Idk how it would work as far as adding power or changing timing goes but it is a bada** setup...

 

lol but it's so dam loud with it advanced that far, my dad's just has the stacks and you still hear the engine(and fan) before the exhaust.

any idea how well the moose pump works?
as well as mel's misters?

 

The Moose pump is decent but they don't use the turbo pump like Dps does. I have a Moose Pump but in my honest opinion if I did it again I woul buy a Dps turbo calibration pump. As far as I know, Dps adjusts the timing on their pumps. I'm not sure if the Moose pump timing is adjusted at all. I do know that their is what most call a "torque screw" is on the Dps pump and the Moose doesn't have it as far as I know. I also have the Dps stage 1s and they seem to make really good power. I haven't had the Moose Misters so idk about them at all.

 

torque screw = low end max fuel adjustment? from what my pops tells me getting the timing right is the most important part or else it will hydro-lock and break the input shaft on the pump.

i am looking for fuel economy when i am not in the throttle, plus, better atomization will give you more power

 

Yep that is the adjustment. Timing is definitely a biggie. After Racin dialed his timing in, he made quite a bit more power. Also economy is the beauty of a diesel. You can have power when you need it and economy as long as you keep your foot out. Lol. My Dps injectors make for decent economy. My truck gets 17-19mpg.

 

i could do without the torque screw in that case. just have to learn to drive the truck.

why do you guys switch to heavier valve springs? is valve float a common problem within normal rpm range?

hypermax is coming out with new head gaskets? it's hard to believe that an engine this old is just now getting the attention it deserves lol

 

They are trying to prevent valve float cus of the new, more agressive cam profiles. Definitely don't want a valve hitting the pston. Lol

As for the new gaskets, they are making them now cus there is renewed interest in the idi where many thought they were gutless and couldn't handle boost for the longest time. This was only the case due to head gaskets going at higher pressures. With a fire ring setup, an idi would handle 30+psi all day long without a worry in the slightest...

 

agreed

maybe i will have to look into a set of them. do they have a release date or are they out?

does diesel fuel break down silicone? why not use high heat silicone o rings in the injectors?

and i wonder if i could put the high idle on a switch as well as use the automatic operation?

 

Not sure on a release date. Last I heard they were gonna work on building them this month. You can call Ron over at Hypermax and he would be more than happy to give you an update. He's really open about what they are doing with the gaskets. If you do call tell me what they said. Its been about a month since it talked to um.

As for the silicone O-ring I have no idea. That is definitely outa my leage. Lol

Also I'm sure someone will know about the idle switch? What would be your reasoning for doing that though?

 

i'd like to put it on a switch if i decide to go with a belt driven air compressor or if i am using a lot of electrical power to keep from draining the batts.

it's really handy to have tools when your out and about

 

Ok I got ya. Keeps the rpm up to charge the batteries.

 

indeed, although to do that it's going to have to be up something like 15-1700rpm (i think that is where it really starts charging)

silicon o rings are bad.... not made for petroleum products. guess i will just have to get the viton rings

has anyone tried air injection into the exhaust manifolds?

 

Are you talking about air injection to help spool ythe turbo?

 

indeed, i want to introduce it as soon as possible, either at the end of the manifold or the start of the manifold. (probably the end so that i can get the pyro in front of it)

got my projectors and fog lights in today, guess i will have to start making the housings.

 

One reason I would be worried about that is that it would increase drive pressue I would think. With an increase in drive pressure, I think it would offset anything gained. I would just inject nitrous as that rate. It has a cooling effect and adds oxygen. I may be wrong but I don't see too much to gain from adding it into the exhaust mainfold. Also any pics of the fog lights and projectors?
