  1. Blew the 4500 on Friday night. Cruising up a hill @20 psi of boost I heard a pop, and I had no 5th gear. I hoped it was just the nut backing off, but it was not. I drained the fluid, and it came out grey... not a good sign. Removed the OD housing, and everything looked okay, so I dropped the trans. Turns out the gear in the picture has stripped out on the countershaft. (Inside part of the gear is stripped) I've never seen a failure there before, but O well. It was bound to blow eventually. I was consider rebuilding it, but after further inspection the entire trans is filled with metal flakes, and most of the gears are showing signs of surface fatigue on the gear faces. That means I would need all new gears, all new syncros, all new bearings, a mainshaft, and a countershaft. I don't feel like putting that kind of money into a trans that will blow again. I'm on the hunt for a G56 to put behind it now. I'll keep this thread updated.
  2. I don't think you'll gain anything. I think you're asking too much of it. That's a lot of weight for around town to get good mileage
  3. Anywhere above 2000 rpm with little throttle input. Having boost makes the comp try to fuel hard. When the throttle is light it fuels hard for a split second then stops because the throttle input is low, and that just repeats.
  4. So it's pretty much what I said... most of them have it. I never stop at the mom and pop stores anyway. Not enough turnover. That's not just the injectors. I went from 125s to 300s and didn't loose that much mileage. 75-90 would help if you still have stockers. Most of it is in the right foot though.
  5. LINK!!! Cheapest one I can find is like 70 Thanks
  6. Like semi truck diesel? It should all be the same. I typically avoid using the semi pumps because they don't have a filter on most of them. It's usually just a screen to stop debris. Regular pumps usually have a 30 micron filter if I remember correctly.
  7. I'd go 4". Keeps the drone down on long trips. 5" sounds SWEET but with a single turbo wouldn't be worth the drone to me.
  8. What were the two mpg numbers?
  9. Fuels smoother, doesn't have that big timing jump the comp does, and can be turned off to get great mpgs. I wouldn't go with the comp version though. It likes to surge like an MF with the comp version turned up at high RPMs. Although, I'm happier with the quad than the smarty / tst stack. That's likely because I'm running huge injectors though.
  10. Yes it does cause that big of a jump. On the highway, my fuel gauge typically doesn't move off of full until 100-115 miles.
  11. IMO the TST is the only box to stack with the smarty. Comp / smarty stack for me was a hot, smokey, lazy turd.
  12. Never an offense. I'm open to all suggestions. Those injectors are too small. I'm shooting for 600+ and I know they won't get the job done. I can pull fuel from the tune easily. I can pull the fuel down far enough I can tow heavily and have zero issues with exhaust temps. It's a work truck and a play truck. How it's set up now works very well for both. I had it hooked to a 20ft 8.5ft tall enclosed trailer this weekend. With my foot on the floor and can-bus only tuning the max exhaust temps were 1202 @50psi boost. Adjusting the boost elbow doesn't do a whole lot. With it closed off the primary is making 20psi with overall boost at 70+. The drive pressure is well over 100 though. With it open it makes around 60psi with 30 coming from the primary. Somewhere in the middle is where it seems to run the coolest. Around 65 overall boost and 25 coming from the primary. Adjusting the boost elbow has no effect on drivability or my DD tune power, as the wastegate never opens. -Right now I don't have any stacks. Just the Quadzilla Adrenaline.
  13. I'm not sure... Last year around this time 503hp 1215ft-lbs. Two days ago on the exact same dyno 518 not sure about torque. I'm confident it was lying on of those times. I'm thinking it was lying this time though because a different dyno had it at 502hp last year too. The butt dyno doesn't lie when there are these big of changes made to the motor. Im not saying is a million HP but I know it makes more than it used to.
  14. This is the same dyno I've been on before. It made 503 with a stock motor, 7x.0095, tst, and a smarty. Are you saying bigger injectors, a cam, and a hell of a lot more air gained me 15hp ?
  15. You make a valid point. I'm still going to guess it was already stress fractured or something though
  16. 7x.013 No, it's the only one I've got right now. Thanks! I'll stick with these for the moment though. I'll send you a PM if I'd like to try them Yes. It's always got a crazy amount of smoke when my foot is on the floor. Even over 60psi of boost. The problem I'm having is this "recipe" (package of parts) has made well over 600 on the dyno multiple times. Heck I've personally watched multiple trucks do it. I normally run the tuner on the fuel mileage setting anyway, so that's probably 300hp or so. It's just stock fueling with some timing. It tows like a champ with can-bus fueling only. Peaked the EGTs at 1202 with my foot on the floor and made 50psi of boost while towing. I should be able to turn the tuner up and hit over 600 though. I did a bunch of runs with different wastegate settings. Wastegate closed down was making 65ish psi with 20 coming from the primary. Wastegate open it was making 55ish with 28 coming from the primary. Wastegate in the middle was making around 60 with 25 coming from the primary. I even swapped in the TST and smarty to see if it was the quad goofing up. Made almost identical power, but the EGTs hit 1830.
  17. The 518 was with the 12cm housing. I don't know if it's the dyno or what. It made more power with the 125hp injectors. It feels like a heck of a lot more power than before.... maybe I'm crazy.
  18. I've been away all week working on the truck. So I started out by dropping in the 5in exhaust. All went in fine there, or so I thought. I then swapped the 14cm housing onto the turbo that Jacob from DAP sent me. I drove it around a bit that night and could not get it to spool. It would take 2200 rpm + just to get 5 pounds of boost out of it. Driving easy up to 65mph the egts would hit 1250deg. My overall boost had dropped off the 48psi (tuner maxed), with 30 coming from the primary. I also had the wastegate completely closed off. So that night I pulled the compressor housing on the secondary and removed the cartridge after that. The turbo looked good, and so did the housing. So I took the back plate off of the wastegate to make sure there wasn't anything wrong with the "flappers." All looked good, so I buttoned it up and took it for a drive. Nothing had changed. The down pipe was also hitting part of the cab and making everything in the cab vibrate. Friday I had a dyno scheduled, so I didn't have time to change the housings back. It lit about 2500-2800 rpm and made 450hp with 650ft-lbs. I started that night by pulling the exhaust back apart and knocking a few dents in the pipe. I also cut off a screw that was hitting. Now it no longer touches. I also swapped the housings back over. I noticed the part where the turbine goes in is significantly larger, so it's not for the 65mm wheel. I got it on the dyno again on Saturday and it made 518. I'm not impressed, and I'm not happy with the numbers. I haven't decided what to do with it yet. Either I'll de-tune it with some smaller injectors and lighter tuning, or I'll start looking for Ppump parts. Decisions Decisions......
  19. These rear ends are pretty tough. Tire size, especially stockers aren't going to cause too much traction and make it break. Like the other guys said, good thing it happened where it did. I'd chalk it up to crap happens when you're playing.
  20. Here's the Wells. I like it. No contact involved.
  21. Mine are almost 4 years old, so it's probably the old compound. Thanks for the heads up! Looks like I should give these a try as well.
  22. YUP! Come to this site, and ask for help. I can't think of anything someone you couldn't get help with. Everyone here has a wealth of knowledge and are willing to share it with those who ask.
  23. Thanks for the heads up. My Michelins have held up very well for the power level, and I would like another tire that would hold up similarly. Only downfall of the Michelin tires is the $1200 price tag that comes with them.
  24. I guess this is the "early" change version! I think I put it in either at the end of July or beginning of August
