I almost jumped on the bandwagon a few months ago and bought an open tang hta35r, but the more I researched the more I realized that twinscroll turbos should have better spool, volumetric efficiency, and part throttle response and still make great top end power so I kept searching. I know I want a a turbo with a divided t4 hotside and a v-band discharge with good street manners and around 500whp on pump and 700+whp on c16. Everything I have read on multiple forums suggests that a 4088r will outspool a 35r and make more power, so I thought I had finally made up my mind about which turbo I wanted... until I read this;
Borg Warner S374 vs GT4088R Comparison Dyno Graphs - FreshAlloy.com Forums
It looks like the BW374 turbo is non bb, and much larger than the 4088 and was also running a little larger hotside and only 2 more pounds of boost but spooled just as fast and made alot more power.
Apparently the ETT series Borg Warner turbos are the cat's pajamas but there don't seem to be that many people using them yet on DSM's. Does anyone have dyno numbers for any of the Borg Warner turbos like the BW366 or 370 on a 2.3 or 2.4 liter engine? Also, I have always read that ball bearing turbo's are more reliable and have much better transient resonse than thrust bearing models. If this is the case, why does Borg Warner seem to use thrust bearings exclusively?
