i ground the afc and put the gov spring in now i am building to much boost. It will go to 50 lbs and i dont want that, i like my head gasket. i try to keep it below 45 lbs. i didnt know if i could buy a gated exhaust housing then buy an auctuater then make everything work. I jsut REALLY and to go full throtle but i cant bc of the boost.

 

Even with a wastegate I think you will still over boost it. At 45psi you might kill that turbo. Doesn't HTT want you to keep that turbo below the boost you want?

 

Ihpower: How's your timing? I know you're running a fair amount of fuel through your truck, but 50 psi seems excessive...and in any event, it's in the danger zone, both for your head gasket and for the turbo. Even 45 is waaay too much, imo. I know Wannadiesel had to switch from the 16 to the 14 w/g to get things under control, but that was with water meth in the mix. The non i/c trucks are just a different breed, I think--what works on the i/c'd trucks seems tu put ours into outer space...short of an intercooler, I'd say kick it down a notch and re-check your timing.

 

Advance the pump as far as you can get it to move, that will help. It seems like trucks with POD's need all the timing you can give 'em.

A wastegated housing will be able to keep the boost under control as long as you drill the divider wall so it wastes both sides.

 

Thanks for the input, but i do have a few mroe questions. How much boost will the turbo handle, i know it is small so i did not want to go past 38 or 40? Will advancing the timing cause any starting problems or any others? And what size gated housing do you all run or what do you think i should run?

 

I bet 35psi is max safe pressure for that HTT turbo. I don't know about advancing the timing all the way. Yes it will cut down on your boost pressures, but maybe its just me, but my truck doesn't like to start anymore with all this fuel and timing . It cranks fine, but doesn't want to keep running. Last winter I had no problems with no grids to below zero temps, now 15-20*f, and it just doesn't like it. I'm probly gonna back off the timing and fuel til spring.

I say time for a bigger turbo. HTB2 62 or the like with a 12 or 14 gated housing. Time you buy a $350+ 14cm housing, you'd be almost there for a much better/efficient 4" turbo- $900+-. Personally I wouldn't run a 12cm on a heavily fueled, non-intercooled truck, but thats just me.

Another thing to do is back off the fuel and keep your foot out of it LOL....

 

Will it cut down the idle haze?

 

Somewhat. It seems like "cranked over to the head" is different on different trucks. I worked on Vinny's truck last week, his is cranked over all the way and it hazes awful all the time. I can't get mine as far over as his is, and mine only hazes if it sits and idles for a few minutes or when it's really cold.

 

Hey Bill, I think it's possible that the 14mm head is supplying so much fuel that you are putting the fire out. Do you get lots of white smoke before it dies? I've driven several old Cornbinders that were touchy to start when cold. They needed a little extra fuel but if you overdid it they would bog down and die in an eye-watering cloud of white smoke. Unfortunately with the starting spring setup in the VE we have no control over that, it gives full fuel until the RPM comes up. You might want to think about hooking those grids back up to get some heat in those cylinders.

 

well i advanced the timing a lot and now i kind got the boost under control. but i still can reach 40 lbs. but this week i am going to try to advance it a little more and see what happens. but over all i LOVE the spring and afc ground. I thought my truck was pretty fast before but the the SOB will boggy. best mod i have done yet especially for the price.

 

Yep, my only regret is that I didn't do it sooner.

 

My only regret will be when I over power the stock 727 tranny. I cant believe they hold the kind of power they do with so mant miles, and stock.

Hopefully one of these days I will get my old cummins up to the kind of numbers most of you guys are running.

 

Yes unbelievable amounts of white smoke before it dies, and will continue if I keep it running with throttle, then when it finally runs on its own, more and more white smoke. Not your normal white smoke, but just as you put it, eye-watering cloud of white smoke.

Yep I think I might have to run the grids this winter and for the first time in 3 years of ownership, actually plug it in. Need to get a timer for that. I hate that 1500 watts of juice being used .

 

Are you serious!!!!! They have 1500 WATT heaters. Thats alot of juice. I figured maybe a couple hundred. Since mine has been plugged in constant for a couple weeks i bet its used a ton of electricity. I'm not worried about the bill because I dont pay for it, but my garage takes 2 1750 WATT heaters to keep it even 65* during the winter. I dont think my garage breakers will hold another 1500. I may just throw an extention cord out the living room window and call it good.

 

Bill,
I have my block heater on a timer set to be on for about 2 hours prior to my "normal" departure time.
