YES GEOFF CRACKED.. Not blue from heat or oiling issue.. used 2 different oil feeds as that was the inital blame before BW inspected the turbo.. i sent one to be inspected and to no suprised they told me the turbo cannot handle the boost levels.. please explain how at 40psi i made 20+ runs and AS SOON as the turbo saw 50psi good bye.. Wait maybe it was a fluke,, 2nd turbo 38-45psi perfect.. Turned the boost up at the track and 50psi good bye..

Then i was told the back housing was too small and it was the shaft speed and i needed a larger rear housing.. No Problem, switched housing and at 50psi same issue.. Then after discussing with jose at forced inductions he said that was retarded to change housings.. all that changes is how much longer it takes to reach the same shaft speed at 50psi..

Switched to a garret with the same oil feed and wow, lasted the entire season at nopi and dozens of dyno pulls at 50+psi.. I even spoke to a very well known sponsored team and they said " We have a line of them in the trailer.. If they arent sponsoring you id stick to the Garrett".. Better yet i watched a car make runs at nopi all last year with the BW and top of the track smoked like a blown motor.. Funny the backup engine never left the stand and they kept going rounds after " Fixing " the problem.. I rest my case..

I also have the Borg Warner maps in lbs/min and am 100% sure you need to correct the overlayed maps since the GT35R surge line is better than the S300 by 5lbs/min.

I personally converted your maps (on the Full-race website) back to lbs/min a while back to see if the Compressor wheels were revised since the 2007 BW catalog, but alas they were not.

 

so it was a forced inductions turbo, NOT an off-the-shelf BW Airwerks. go visit supraforums and look up some of his postings you will see some unsatisfied customers. please stop polluting this thread, if you care to continue the discussion PM me or email me

 

BW Compressor maps in lbs/min can be seen here > http://www.airwerksboosted.com/Files...talog-2007.pdf

Some of Garrett comp Wheels out do some of the BW Wheels, if you compare them based on their relative efficiency islands and surge lines, so pick the Turbo best suited to the Engine and your HP target.

 

actually if i remeber correctly it was a bullseye s372 (r cover .90ar)...

 

those are NOT the same turbos. these are brand new 2009 airwerks units. completely different

 

Which header coating are you using?

 

I refute such a comment.

Do you honestly want me to convert the map you provided from Kg/s to Lbs/min for you in front of everyone here ?

 

No it was not Forced Inductions Turbo.. Where do you get that i bought it from Forced Inductions from " After discussing it with Jose @ FI "??

I was discussing it with Jose since i bought my 4202 replacement for BW.. He laughed when he heard i was told the backhousing was too small and the larger housing would solve the issue.. I feel more confident getting 1st hand info from a guy who sells 5 different turbo companies turbos.. He said he would NEVER put me in a BW unit for what i was doing with my car..

I dont need to go to Supra forums to look at who is and isnt satisfied with FI.. i could go there and look at who is and isnt satisifed with Titan, You or anyone.. there is no Pollution, i just dont want to see someone get screwed on 4 turbos in a row if they are actually trying to make power..

I ran a 6262 BB Precision unit to 49 psi and beat the **** out of it without issue.. There are a lot better options than BW IMO..

Mike

 

Oh, So new Units.. Ill buy 1 from you if you stand behind it when I put 50-60psi thru it and it fails.. let me know.. I loved the 372 i used to run for the 1-2 passes it lasted.. Outspooled the 4294, stayed on boost better, just didnt last..

 

Here we go, I don't remember ever in the history of Compressor wheels where the choke line began at 0lbs/min.......

Since your pic is so poor, I've linked the exact same one off your website for people to compare and verify > http://www.full-race.com/catalog_ima...%20compmap.jpg

Now here it is converted to lbs/min, feel free to now overlay it correctly over the GT35R Compressor map and also to compare it to the S300 Map in the 2007 BW Catalog I linked on here as well.

You will find its the exact same one. Sorry but BW do not go manufacturing new Compressor wheels yearly just because they can. No Turbo manufacturer does.

But would you like me to email BW directly and post their response to such a suggestion ? I'm sure they would be more then happy to clarify the propaganda.

 

What does BW use as standard inlet conditions?

 

I think Mike meant to say the BW units were supplied by Bullseye. If shaft speeds are kept in check with the BW units they do last a long time and make killer power. If you start to spin them hard they fall apart quick. The Garrett's take severe abuse and over spinning a lot better and keep on ticking, non-bb or not.

 

But the BW should be fine for subies we cannot boost 30+ safely on a build block

 

Is it just me or is there an echo here ?
