Wow... . what a difference!



Now, in any gear, any speed, a little shove on the pedal and the turbo whistles and the engine responds almost immediately.



Once I change injector's it'll probably do cookies in the parking lot if I wanted (I don't, those tires cost a lot!!!). It's very, very responsive, and I can't say it's lost any power on the high end.



BTW, I moved the timing up a bit (not measured), and changed the turbine housing AND set the wastegate to begin opening at 18-20 PSI. I don't have a boost gauge, but as far as I can tell, it will make full boost at any point except the first few moments from a dead stop.



And what a noise :)



It never whistled before, it does now. And, at idle, you can hear the turbine whine in the exhaust, and coasting down at slow speeds, there's lots of fluttering whine, too. Even at 25 mph on the flat, it makes some turbo whine mixed with the engine pulses.



I thought the exhaust would be quieter. . . I think it's louder, not quieter.
 
I'm seriously considering muffling it.



I'll wait to decide that until I tow the trailer with it. Then, that'll be the deciding factor. Too much noise, it gets muffled, otherwise, probably not.
 
Hey Powerwagon

Glad you are getting to have some fun, I am having fun watching your posts about all the cool stuff you are doing.
 
heh, so far, it's very little money



I've got to tow my trailer with the truck, probably going to Alaska this summer, so it means it really does need a lot of this stuff.



Wish I had money to do all the really cool stuff, but hey, I'm happy now!
 
PW,

Great to hear! I just got my exhaust re-hooked back to muffled, and it's great. I am not an old fart either, but the 12cm^2 housing just rips up in the noise department :D My truck pulls about the same as yours, but I did you notice a drop in EGT's, my truck runs a lot better. Now I have less smoke, lower EGT's, and a truck that has useable power... . yeehaw :p :D

Welcome to the club!

Hey Power Wagon!



Great to see you as a card carrying member of the 12cm2 club!:D



If you decide to muffle check out the Walker #21468 or a Dyno Max straight trough - perforated core. Both of these mufflers seem take the edge off the "noise" and just let the Cummins Classical Music flow.



KEENO:D

Sure. If he's game, I'll stop by. We may disagree with every fiber of what we are, but that doesn't mean I am disagreeable in person.



I'm not expecting to spend time in Fairbanks, actually, but since it's not determined where the wife's going yet, I don't really know. I told her to ask for Anchorage, but it could be anywhere, including the places you can't drive to. Or maybe they need someone in Dead Horse... that would be cool - well, for me anyway. I think the wife's enthusiasm for adventures into hostile lands is a little less than mine :)
 
Hey PW if you come to AK this summer give me a call or look me up or what ever. Do you have plans now??? If you need info let me know. I might even be able to arrange a fishing trip if everything worked out right.

Your offer is most generous... However, I'm not a fishing guy. Scenery, photography, video of animals, etc... THAT's my thing.



Just think of me as a fanatically right wing nature lover :)
 
Well then I will leave the fishing rods behind, we can just float the river and look at the Eagles and Moose and bears... . and the fish if they jump... . either way look me up. Heck we might even have to have you as a special guest at a Bombers meeting.
