Re: (SPOOLINmatt)
No, Only available in the 9" cover with gigantic tube outlet. Joe welded a V-band on the outlet of ours, which made it almost a direct replacement for the 42R.
There are a few of these turbos on the shelf, lead time otherwise to put them together is about 2 weeks.

and again, the power drop up top is a slight miss due to the distributor taking a dump.</TD></TR></TABLE>
sold, if its really 500 less. this thing is well worth it. i'd use it in a dsm.

Re: (Boner_Ben)
what boost are those high boost pulls at?
@6500 the bw is making 400 and the garett is making 450.
wheelspin shouldnt occur at that hp level

I agree...i assume that if there is wheelspin at that level then there is also wheelspin on the 779whp garrett graph???
As for size, other than the inducer being smaller on the garrett, the exducer on the BW is much larger, and the turbine wheel is slightly bigger. So saying the gt4294r is a bigger turbo is kinda leaving alot of grey area...
For the testing! Im not bashing Borg Warner either, i think its great that they are offering sizes that Garrett doesn't to fit the rule book (or whatever they call it now a days..) ... to making more power!!!

Re: (GodFather of Boost)
boost is in the 38-40psi range on both turbo's.
the car was put on the dyno 2 seperate times. anybody who dyno's high horsepower FWD cars knows the temp of the tires, the temp outside, and most importantly how the car is strapped down makes a big difference in wheel spin. we must have had it strapped a little better with the 42r. who knows
also keep in mind this is done on a stock head with stock gsr cams. the cylinder head / cam package i run on my personal car absolutely dominates any other 42r car we have ever had on our dyno in the mid range and the power carry's out to 11k rpm (as long as the boost is low enough that we are not at the limits of the 42r). nearly any dyno graph you see posted of a car in this power range has at least a set of R cams in it.
the way i look at it is.....a 42r is not legal for power street. if your looking to make this kind of power, and are not trying to fit into a 67mm turbo class.........get yourself a S372 and make another 100+ horsepower
i know thats my goal haha

This guy said my exact thoguhts...It has a bigger exducer which in return throws a wrench in it and should show bigger number but fools the average consumer into thinking that there new 68mm bullseye turbo is the best new bandwagon toy then there old trusty 71mm GT42.
By the way I would run a BW turbo if it fit my power goals, my fabricator/welder runs the BW turbo's at levels way above any listed here and he likes them. There was some guy at USP in FL recently that broke 3 BW turbo's in one weekend and his GT42r lasted no problem, go figure.
I could be completely wrong but the way I look at it, buy what ever size turbo you need, garrett/BW/turbonetic. Some will make more then other but technology is bringing everyone closer to each other.

Re: (SOUNDEFFECTS)
The real purpose of the test was to show the capability of the S368. For me personally, I wanted to race in powerstreet where there is a 67mm turbo size limitation yet I also want to throw some slicks on for BOTI and test n tune and run deep into the 9's. Same goes for K series and ecotec's running turbostreet. I'm sure there are alot of people looking for a turbo that is the best of both worlds and this fits the bill perfectly!

Sounds like the guy that went through several BW turbos was getting oil from the wrong place or must have had a -3 line on it. We have run into people replacing ball bearing turbos (which most are use to restricting oil flow since bb units don't need much oil flow) with out turbos and sometimes have a restrictor in line or using a -3 line. Both will live OK on a ball bearing turbo but will not supply enough oil for a journal bearing turbo. If the guy had an EVO he was probably getting his oil from the head which looses oil pressure all the way down to about 20 psi by red line.
Bottom line here is, turbos don't fail on their own. </TD></TR></TABLE>
you saying a -3 line by itself isnt sufficient enough? Thats all i have ever ran on any journal turbo without restrictors.

Re: (Turbo-charged)
do you have any 30lbs pulls that both turbos didnt get any wheel spin?
not interested in peak power. powerband is way more important to me.

Re: (GodFather of Boost)
i'll have to look....i didnt rename the runs with boost levels, i'll have to do that next time i guess.
just picture that 10psi overlay with higher numbers LOL.
