Um. "water lines"?

 

i think all ball bearing chargers are oil fed and water cooled.

 

Sorry, brain fart. For some reason "water" did not translate in my head as "coolant", even after looking at it three times.

 

LOL... especially the VGT turbo's ... they hate being hot ...

 

Yes they are I should have said coolant not water, have you seen any of the powermax gt3782r units in person? If you have is the turbine housing bolted on or held on with a v band?

Personally I think that charger would be sweet in a twin set up if money is not an issue, there stage 2 unit with the internal wg is the one I would like

 

we still havent seen many of them come in the door. i think its still a -fad to come- ive heard good things from a properly spec'd ball bearing but havent had the chance to ride shotty. So no i couldnt tell you how they go together. I had the chance at the extravaganza last year to get a good look at borg's new ball bearing line. they are utilizing a different material in the turbine wheels which are much lighter then inconel. something like half. they look sweet and the idea is cool but again i havent seen on on a truck or have any experience with them. i also believe they are ceramic ball bearing

 

I see, the gamma ti turbine or something like that is what is in the borg efr's have not heard a lot about them really.

On the garrett I have heard good things about trucks running them as a single on mild power trucks (450 ish) but nothing for twins

 

same here. i was thumbing through an old diesel tech mag earlier and they had a 12 valve compound build with a GT3788R over a GTX4202R, claimed they were worth 1000hp together. it was a decent read. im still however not a big garrett fan. the quality of everything on them is very sub par when compared to a holset or schwitzer turbo. why do you think every turbochargerd truck coming out of the factory doors comes with a garrett? price. cheaper parts makes the big companys more money. most of them we wont even reman, its just cheaper to replace.

I'll have to see if I can dig it up, only thing is that 3788r has a slightly bigger turbine than the powermax unit exducer is 2mm bigger

 

says here the 3788 is a 64mm compressor inducer and a 68mm turbine inducer. says nothing about exducer size. the 4202 is a 75mm comp and a 105mm ind turbine
