Installed the 16cm housing today, took it for a test run, she'd only do 24 lbs of boost, the old housing was a 18.5cm and would build 22 lbs. Came home, adjusted diaphram 90*, same thing, adjusted to 180* and a little better, turned star wheel 3/8 turn, a little better, but still only 25 lbs boost. Came in and thought about it, went back out and turned star wheel 3/4 turn, it's was getting dark and I didn't want the man to get on me for running down the road, so I'll have to try this one in the morning. What I did notice most is at wot it seemed to not have the pull that it did at the higher end. My main problem is that I have my eye on an airstream, about 25-30 foot long, almost got momma talked into it, but I don't want to spend the money on all the goodies for the truck, it act like a dog, and me have to sleep in the dog house when she realizes it's no better now than it was before. But i did notice the EGT's went down. Fuel screw is bottomed out, maybe on Sunday I'll put the pods back in and undo the "adjustments" to help the smoke problem. HELP

Do you still have smoke at full power? If not, the reason you're not getting more boost is that you don't have enough fuel to make more boost. The fact that your EGT went down tells me that you now have enough air for the fuel that you're burning. Remember that boost does not equal power. Ideally you want enough boost to burn the fuel you're injecting, but no more. Additional boost just EATS power because of the backpressure caused by making the boost. Don't be disappointed, the lower EGT means you can add fuel again to make more power.

I had a 12v 94 model, the thing that sucks about the 12v is even with upgrades you don't get a whole lot more power.

i chipped mine and 60 horse injectors and 4 in exhaust and still only got about 215 horses out of it. good luck.. You might try diesel performance specialists they have some pretty good upgrades for those 12vs . they have a web site I think.

Thanks, I'm going to try and install the pods again in the morning and see how that goes, after I make a run down the road to see how the 3/4 turn on the star wheel has helped. Last run, I had 1050 on egt, but I did notice that boost pressure stayed steady with the 16cm, with the 18.5 it would run up and then back off??? It's just that the pods smoke so bad, and all that is, is unburned fuel, $$$$$$ out the tail pipe

Wannadiesel, I was trying to talk to momma and type, guess who had better get the most attention it had a lite haze on the last run, but no real smoke, I also turned the smoke screw in a "few" turns after moving the star wheel to 3/4 turn, I'll see in the morning how it does, and let ya know.

Playin' with the star wheel and smoke screw just tunes your response and smoke off the line, but adds nothing to the top end. If your fuel pin is set for the deepest side, youre getting all the fuel your current setup will give. It sounds to me like you should be able to use the fuel the PODs put out, or at least some of it. That main fuel screw can be turned counterclockwise too, you know. The reason your 18.5 was dropping boost at the top end was that the governor was starting to defuel the engine. The smaller housing is able to keep the boost up despite the lower drive temp/pressure caused by the defueling. Have you thought about the governor spring? More RPM=more HP, plus you get a wider powerband which means youre in the right gear more often when towing.

Wannadiesel, I just today got the gonads to open up the the thing a ma jig on top of the pump and play with it, don't get me wrong, but I'm used to building things that run within .0015 clearance, and another .0015 will kill it, and cost us some money, so when I hear "turn it a 1/4 turn" It gives me the pucker factor x10". Momma has already said " keep F with it and you'll be driving the ford again" and the Ranger sux. I'm gonna make a run down the road in the morning. before the police get out of the doughnut joint , and then put the pods back in to see how it works, but I'm thinking that the EDM's are the way to go.

Didn't get a chance to install the pods this morning, had an emergency repair job to do at a hospital this morning, before I even wanted to get out of bed That's one of the NICE things about working for yourself, no rest. I just said the heck with it and will be ordering a new set of EDM injectors that Don makes from Rod, he says they won't smoke as bad as the pods, but still give 40-50 more hp. I ran the truck up the same hill that I've been using to test, 1/2-3/4 mile long, nailed it at the same spot today and only got 22 lbs boost. Star wheel is turned 3/4 turn and diaphram is turned about 180*, maybe too much. I know you need fuel to make boost, but I had 25-26 yesterday on last run, can 90* on the diaphram make that much difference??? But I do not have any turbo lag, you nail it and it goes. Oh, and don't anybody tell momma about the edm injectors, she'll get really PO'ed
