View Full Version : how much boost kast 07-18-2006, 08:45 PM well i just picked up an 06 crew cab longbed 4x4 lt2 now i would like to know if i can get more power out of the stock turbo or what kind of upgrades i can do. http://img.photobucket.com/albums/v299/kast_xh/Vince_Truck.jpg dozerboy 07-18-2006, 09:19 PM 30-32psi tops, how much power do your want? And why drag race, truck pulls, towing? Your first mod needs to be your tranny. kast 07-18-2006, 09:52 PM what would u say that i should do to my tranny. im not looking to drag race just seeing what kind of power i could get out of the stock motor. how many pounds of boost does the stock turbo have. section9z71 07-18-2006, 10:16 PM dont go too big on the stock motor. head gaskets go. as for tranny, go with a BD torque convertor. valve body. then for more power, possibly look into the BD intimidator. try mbrp 4" exhaust too STLCHEVYHD 07-19-2006, 05:06 PM I've read a lot where the stock LB7 will hold up to 500hp on the turbo, injectors, etc before it can't go no more. So, I'd imagine the LBZ would do the same. But like they said, the tranny will need modifications to withstand the power increase. dozerboy 07-19-2006, 06:27 PM If you really want some power and are willing to add drugs or mod the block get the best tranny out there Suncoast stage 5 or the ATS stage extreme 4. It you just want a pretty fast ~500RWHP truck Suncoast stage 3 or comparable. Stock is 22-23psi. Exhaust is a must and stock intake should be replaced if you want to go higher than 500RWHP. Gauges are a must. With drugs (n2o, propane) stock motor has hit 800RWHP. But daily driven fuel only 500RWHP is about it before things start to go, but the LBZ should hold more yet. I suggest if you really want to get into Dmax performance join dieselplace.com and do some reading and searching. r1_hauler2 07-20-2006, 01:02 PM dont go too big on the stock motor. head gaskets go. Do not worry about head gaskets!!! Chevy had a problem when the duramax FIRST came out, that has been fixed for YEARS already. Listen to dozerboy he speaks the truth. section9z71 07-20-2006, 01:31 PM when did the first duramax come out? r1_hauler2 07-20-2006, 02:49 PM the duramax was released in 2001. dozerboy 07-20-2006, 06:39 PM Stay away from BD for tranny mods unless you are going to stay under 400RWHP and head gaskets are still a problem when exceeding 60PSI without head studs. r1_hauler2 07-21-2006, 06:47 AM Stay away from BD for tranny mods unless you are going to stay under 400RWHP and head gaskets are still a problem when exceeding 60PSI without head studs. LOL well thats a given. However, the most common tuners/chips will not push you to that limit causing that failure. dozerboy 07-22-2006, 05:26 PM No tuner will, adding pane can its all about cylinder presser. Hey what can I say he wants power big power needs a big turbo? :yumyum: :burn: r1_hauler2 07-26-2006, 07:44 AM No tuner will, adding pane can its all about cylinder presser.

That'd be more than adequate for a stock truck trying to get a bit more. That being said, keep in mind turbos are not bolt-on horsepower! It has to be matched to your fueling/horsepower output for the best results, so bigger isn't always better. r1_hauler2 07-26-2006, 02:15 PM If only they'd fit under the hood...:dunno: They do I know of a few people over on the diesel place that have gone and added twins.:cheer: dozerboy 07-26-2006, 10:35 PM You push a VVT turbo up to 40psi plan on buying a new one. I have heard of 52psi from a stocker now it’s a paper weight anything over 32psi is asking for it. And twins are no problem just need to relocate one of the batteries. LostBoy 07-27-2006, 03:27 PM They do I know of a few people over on the diesel place that have gone and added twins.:cheer: I'd bet if you ask they had to do some cutting on the body to make them work - I don't know of any bolt-on kits but I'd be curious to know who is making them if I'm wrong, so please post back with that if you find out... You push a VVT turbo up to 40psi plan on buying a new one. I have heard of 52psi from a stocker now it’s a paper weight anything over 32psi is asking for it. kast's question was what what the stock turbo can do - that being said, I haven't heard any problems running the boost controller - be thankful we own GM's & not Fords, whose VVT's are dropping like flies, even on unmodified trucks dozerboy 07-27-2006, 09:51 PM I'd bet if you ask they had to do some cutting on the body to make them work - I don't know of any bolt-on kits but I'd be curious to know who is making them if I'm wrong, so please post back with that if you find out... kast's question was what what the stock turbo can do - that being said, I haven't heard any problems running the boost controller - be thankful we own GM's & not Fords, whose VVT's are dropping like flies, even on unmodified trucks :whyme: :read: There is o cutting of the body you only need to relocate the battery. There are 2 companies making them they are in-house mods not bolt-ons. And like I said push a stocker over 32psi it won't live. r1_hauler2 07-28-2006, 07:17 AM Idaho CTD is a company that makes twins for the duramax however they do not have a webpage. I have heard banks was making one but hasn't released it to the public yet. And finally try here www.dieseltrans.com LostBoy 07-28-2006, 12:37 PM ...And like I said push a stocker over 32psi it won't live. That may be true of the LB7's, but there you can get that truck moving without really exceeding that - some of the boost increasers on those caused problems because they were mechanical components that bled off some pressure to fool the wastegate. The VVT's controller is electronic & just modifies control over the vanes - like anything else if you run it at the limit all the time, it won't hold up. If you use the extra boost capability sparingly it should be okay dozerboy 07-28-2006, 07:05 PM No it won't, there is one guy who has killed a 05&06 turbo at only 35PSI. kast 07-30-2006, 06:29 PM anyone from cali that has upped there boost? can u tell me how u did it or what shop u went to for it. my friend has 240xs and he can turn up the boost and turn it down. im not looking to hit 600hp just a little more power. this truck is a everyday driver and i drive a lot. so far iv had my truck for 1 month and have 3k miles. LostBoy 07-31-2006, 10:50 AM No it won't, there is one guywho has killed a 05&06 turbo at only 35PSI. One guy is now representative of all Duramax owners? To reiterate, any given component's longevity is relative to the conditions it is subjected to on a regular basis as well as to the driver creating those conditions, regardless of whether it's stock or modified. dozerboy 07-31-2006, 07:30 PM No your right one guy means nothing. So prove your point, show me one Dmax that consistently runs 35psi or over that has lasted for at least 1 year. One thing you’re forgetting about or in all actuality probably know nothing about is turbo efficiency. The stocker is out of its efficiency range over 30-32PSI and the motor will actually make less power when running above that range. And show me this boost controller that ups it to 40PSI, because the only tuner that modifies boost IIRC is the Predator V2.02 and ATS doesn’t sell it. dozerboy 08-02-2006, 10:41 PM Well I owned myself, I found a truck that did run daily and many 1/4 mile passes at over 35PSI until the owner wised up and cut the boost back, but 30-32PSI is still optimum. I still stand by the fact that if you run your stocker over 32PSI your asking for it. LostBoy 08-03-2006, 08:22 AM Well I owned myself, I found a truck that did run daily and many 1/4 mile passes at over 35PSI until the owner wised up and cut the boost back, but 30-32PSI is still optimum. I still stand by the fact that if you run your stocker over 32PSI your asking for it. :fsc1: for me! I kid - in all honesty if you look through all my posts I wasn't disputing that it isn't his best bet to increase performance, I was just answering Kast's question at face value without getting into it any deeper - he wanted to know if it was possible to turn up the stock turbo's output, and all I was doing was showing him something that would & telling him what boost it'd allow. Outside of that we're pretty much in agreement on the fact that the harder you push it the shorter its life is going to be. In reality if he's looking for better performance, he should start with the basics: electronics, intake, exhaust, and strengthening the transmission. If he wants to go beyond that & really crank up fueling, a good aftermarket performance turbo's a safer bet that'll give better performance when matched to his truck's output than turning up the stocker in any case. Glad we're able to get things back to a civil level! dozerboy 08-04-2006, 09:00 PM Civil??? **** you you ****ing jackass!!!!:slap: :middle: :middle: j/k :wink: LostBoy 08-07-2006, 10:19 AM Civil??? **** you you ****ing jackass!!!!:slap: :middle: :middle: j/k :wink: :LOL: duratothemax 08-14-2006, 06:32 PM I have heard of 52psi from a stocker holy crap who did that!?!:eek: dozerboy 08-14-2006, 07:01 PM I have no idea, but I also heard he tried to see how high his tranny would bounce out of the back of a Tahoe. duratothemax 08-14-2006, 07:11 PM I have no idea, but I also heard he tried to see how high his tranny would bounce out of the back of a Tahoe. LOL what an idiot! cl1986 09-04-2006, 09:33 PM I got the edge juice chip on my 03 and my boost never goes over 21....most of the time it reads 19 on WOT....] Ive also noticed that if you really stomp on the gas it wont let the tranny shift......about 1/2 to 3/4 way to floor is quickest 0-60 time for me.... Or is this my tired tranny at 100k miles?? What do you do to get over 21 psi??

Or is this my tired tranny at 100k miles?? What do you do to get over 21 psi?? different turbos, an 03 has a wastegated turbo, that would limit the amount of boost, an 04.5 and newer has a VVT turbo, that doesn't have a wastegate, the boost is electronically controlled, and can be electronically manipulated. dozerboy 09-06-2006, 08:41 PM I got the edge juice chip on my 03 and my boost never goes over 21....most of the time it reads 19 on WOT....] Ive also noticed that if you really stomp on the gas it wont let the tranny shift......about 1/2 to 3/4 way to floor is quickest 0-60 time for me....

And the edge gets it reading for the stock sensor and it's not very trust worthy. vBulletin v3.5.1, Copyright ©2000-2008, Jelsoft Enterprises Ltd.
