I have a 97 dodge 2500, just had the pump plate and possibly the nozzles polished? :--) A whole lot more power. The reason why I say possibly about the nozzles. Is that iam not sure if they can dyno and do this all in 45 minutes. that was how much time was on dyno stock run to mod run. Also they stated that they leave the waste gate hose off, so to bring more boost. I just installed three gauge set, noticed boost up to 30psi, also temp aft turbo at 650 flat road 950 up hill. Should I leave hose off. would these mods be something I could do at home, my buddy wants to do it to his dodge, ( i. e. me gunnie pig, what a friend ). Also what to do about the convertor switch by pass good or bad. Thank you for any help, or advice

yes the mod can be done at home the easiest way to do the wastegate hose is a small per of vise grips its hillbillish but works great and you don't have to plug the hose and then worry if they leak.



the convertor switch I asume you are talking about the hillbilly switch to lock it up don't do it unless you have you vavle body worked on other wise the computer won't unlock the convertor when you flip the switch off. But you can buy a torque locker from bully dog there 200 dollars but work whether or not the valve body has been worked to alow you the lock and unlock the convertor.

I personally think you would be better off using a hobbs switch or a boost elbow to control the wastegate.



950* post turbo is pretty hot empty!!!



The plate would be easy to do in 45 minutes. heck, its easy to do in 15 minutes.

I have no idea about polishing the nozzles though. Maybe they just pulled the injectors, cleaned them and put them back in??? I dunno...



What did it dyno at?? Fill out your signature so that we can know what truck you have and stuff.

sorry fellas like i said iam a newbie. I was loaded s&s 9. 5 foot camper and 16 foot trailer with three quads. ready to play in the snow. They said they would be polishing nozzles in the pump?. It dyno at 121 pre mod 171 post mod. Like i said they took the hose completly off the waste gate and pluged other end. But wont that cause to turbo over spin. I am a little no wait a lot worried about hurting my truck. One of the school buses rack stuck on full. Boy did I have my hands full trying to suffocate.

From what I understand, the waste gate is there to limit the boost pressure. At 30 psi, you are probably running towards the top of the pressure range for a stock head gasket. Hard to say if you will actually have a problem in the near term or not. Although my daughter's 96 has had the wastegate hose disconnected for several years without problems. If you are uncomfortable running with it disconnected then hook it back up. I think the fuel plate could be installed by a good shop in less then 45 minutes (I couldn't do it that quick but I'm kind of a klutz) and a single/couple of dyno runs only take 5 or 10 minutes; however, I'd think it would be difficult to pull, clean and reinstall the injectors in the same 45 min period. I'm not aware of any nozzles that can be polished in the pump.



Be aware that EGT temps will also vary with altitude. I can pretty easily hit 1000 deg on hills locally even when empty.



Also, if you have a stock automatic transmission, you need to be careful when installing higher perfroming injectors, fuel plates or messing with the torque converter/valve body because the stock transmission is a bit prone to failure even with trucks developing stock horsepower.

I wonder if they meant deliverey valves. maybe they reemed them out or something. hmmm.



As far as the wastegate's function, the purpose is driveability. It is there so that you can run a relatively small turbine housing, allowing quick spool up and still be able to keep from over speeding the turbo itself.



You will sometimes notice an increase in top end hp with the wastegate actually functioning. It will also help lower drive pressure in 3 cylinders.



30psi isnt that high though. you wont hurt the head gasket or turbo at that pressure ratio, at any altitude.

I wouldnt worry about blowing your head gasket at 30 psi. I hit 45 psi running nitrious on my stock head gasket and never had a problem.

 

[JGrover]

Nothing to worry about at 30psi. The tst boost elbows are nice, adjust with a allen screw But tst says only there tech guys can adjust it. They told me to put my stock elbow back on I was at 45psi boost. Backed the allen screw out, And still up at 40psi Stock elbow in 40psi Wastegate adjustment time :{
