So say.. Driving like You stole it, MPI twins, Hot Street Tune (most of the time), Tranny, exhaust. ? ? No Dual Cp3's and stuff like that. 84k isn't to bad, was hoping for more
single vs twins please help im not trying to start a flame war

I drove a hot street tune in my 07 LBZ all the time and it worked just fine. I sold the truck with 86,000 and the new owner loves it. It will last as long as you take care of it.

facts are facts man some trucks last some don't... if i was you i wouldn't spend the 5,000$ on twins or any aftermarket turbo if you aren't willing to take the chance of breaking your engine
I would go further and say, I would leave it totally stock if you aren't willing to take a chance of breaking it. That isn't to say they don't let go at stock levels, but at least it will be covered under warranty if it's stock. Fact of the matter is, sometimes s*** happens.
As for 1000 HP fuel only on an S480, I say try it and see what happens. I'm not gonna say it can't be done, but I will say it won't be easy.
The bigger turbine will need more air (more RPM) to spool, you can get plenty of heat from a single CP3 IMO - it's just that by the time you are into the RPM that the turbo likes you are going to use up all the fuel you have to offer very quickly and your top end will be very fuel-limited.
On the converter, the reason it doesn't drop as much RPM on lock-up is because it does it's job while it's not locked and has fluid coupling:thumb:. The fluid coupling brings down the converter slip speed and puts a slow and steady load onto the motor while accelerating the truck alot faster, so by the time the lock-up happens you don't have much converter slip speed for you to drop. On a converter with less fluid coupling you put less work to the ground while it's not locked then it has a big drop in RPM when it locks - with enough power the slip speed can be high enough that the TCM doesn't want to command the lock when it should, hurting your times even more. I have been waiting for an excuse to pull my 1058 and get a Precision converter ever since I started installing them in my builds - the fluid coupling is just awesome.

ya im not a fan of the 1058 in IronHyde at all....71mm turbine/64mm ETTcompressor S400 on a stock motor, stock injectors. it couples very differently when at Part Throttle than at WOT...maybe thats normal, but it annoys me because my natural instinct it to hammer it while trying to go fast and it, in-turn, slows me down since it doesnt couple at WOT until about 80 mph
I'm not talking about the 1058 having good fluid coupling, I'm talking about the Precision having good fluid coupling and explaining that that is why they don't have the big RPM drop you see on other loose converters. My 1058 doesn't couple for crap with this much power and now it isn't even holding the power - it was letting go on the dyno and while logging it on the street I am getting TCC slip even cruising let alone being rough on it. It has finally given me an excuse to upgrade to a Precision so that I can see what 800+ hp feels like when you actually have good fluid coupling.:thumb:
ya i understood what you were sayin dustin, mike had given me a rough explaination of them a while ago. i just hadn't understood that they were coupling better than the other converters out there when unlocked as well.
in anyone's experience is it unpleasant driving with a high stall converter on the street?
and just to get more discussion going, how well do you think a GT5533 with a 1.0 housing will drive on the street?lol.

on a single CP3 , 11.8-12.5 depending on driver , 60 fts , weight , and how hot the truck owner wants to turn the fuel up ect .........

I don't see why it would be. Just because it can stall to a higher speed doesn't mean that the truck won't drive fairly normal on the street. Again it gets into if it has good fluid coupling or not. Some loose converters are just all around loose and don't couple well - that I could see not being fun on the street, especially towing in town.
Good luck spooling a GT55.
it would be nice to have a stroker and try it.....but mine isn't....maybe down the road a couple years i'll have the money and another truck so i can build an all-out competition motor and chassis. for now i think i might go ahead with the S480 plan with a stage of nitrous or 3. with this in mind and the fact that i will be DD this truck too, would a .90 housing with a WG be a good choice or should i go with a 1.00 housing do you think?
I am not concinced that the extra .4 cubes from a stroker is going to create miracles on spooling turbo's , ya it is going to help a bit but ? Plus me personally i would never want to DD a S480 truck , not saying it cant be done just not very much fun to drive unless you dojnt mind smoke and high part throttle EGT's , When i ask Matt about DDing his truck with the new turbo his exact words were " its a peice of shit "

i'm kinda surprised nobody who has 3.2 single has seen this thread. maybe i should start a new thread specifically for this topic. i dont want to keep guessing about particulars like which cam they are running, what size housing, etc, etc. i want to thank you Trent and Dustin for trying to steer me in the right direction....i would do twins if i could budget them....and for all i know i might be able to, but the way it looks right now i can't, even fabbing them myself with my friend. i've already got $20k in parts on the list and being paid for already, sans the turbo(s). whatever i choose needs to be streetable with a built motor, forged pistons, race cam...and run low-mid 10's to compete in SS.
I personally chose to spend my "airflow " money on turbo's and not engine mods especially atfer seeing the kind of power that could be made on stock cam and heads and also considering 5000.00 for an aproximate hp gain of 50-70 hp it was a pretty easy choice for me , wont know untill i run the truck how it worked out or not but i suspect it will still be able to make 1k hp on fuel even though i am not shooting for that # I need about 950 is all for my goals , weight reduction and ET is far cheaper than Horse Power IMOP.
5400 lbs and 950hp will require a liscence and cage so just something to consider .

Should be a very interesting year with the new trucks and builds that are being done. Hope we have somewhere to race, I don't like what I hear about drag strips potentially closing. We now speak of 1000 RWHP in every day terms, wow!! Only a couple of years ago that was an unheard of goal. Spooling a GT 55 on it's own would be a trick. I know how it spools in a big set of twins, and I don't think it would perform very well as a daily driver and with a tight housing I agree with Trent, the EGT's might be a bit much. Mind you I saw 2000 degrees on my 02 GMC with a A2000, propane and 50/50 H2O/meth when we were doing that one mile hill pull in Montana, and for 20 or more seconds. Didn't melt anything but when we tore the engine down the cylinder walls were so heat scored they wouldn't use the block for the first engine build for Max'd Out.

IIRC they don't make a .9 housing for a 87mm wheel so you would have to cut out a .9 housing from an 83 up to the 87. I wouldn't run a compressor any bigger than my 75mm on an 83mm turbine, especially for drag racing. Jeff Dean (stingpuller) drove his S480 on the street too, but not long before winter. I think to truely be streetable and able to tow and what not the S475 with 83mm turbine is about the biggest you could go, once you step to the 87mm turbine it is going to take alot more spool it.
i hadnt even looked into what housings were available, thanks Dustin.
Ken, are you guys using a 5533 now on Max'dOut?
Trent, i agree it's cheaper to address other issues other than HP.
i am not even sure of the limits of my build, as far as anyone knows noone with one of Tony's motors has reached it's limits, and that's with stock main caps even. i haven't heard of anyone taking one of his motor's much over 1000hp as they are mostly sled pullers with 2.8-3.2" single chargers set up much like his truck (from what i have seen).
i plan to take it over 1000hp and my target raceweight is <6600lbs.
the cheapest/best value twins i figure = an externally gated s472 and either a S590 or HX82 or GT5533
home-made this would run me between $5-7k
for that money i also have the option to do a SC/turbo combo, which i would prefer instead of twins.
so this leaves me at:
spray the hell out of a S475 or equivalent to 1000hp and beyond:rofl:
or lay down the big bucks for another stage of air

Just FYI my truck will be using a S300 66/74/16 , and a 105mm S500 . Maxed out went 9.94 on this turbo kit .
