Message: [QUOTE="JDub, post: 1082834, member: 206"] My opinion, the 8374 is going to be too small. Its only a 65mm turbine wheel, so yes it would spool fast but I think you'll over spin it and blown it up in no time. The lighter Gamma-Ti turbine wheel/shaft will only support about 115,000 rpms, which isn't much considering an s300 can go to 170,000+. I run the 9180 on my Duramax but run a wastegated housing and the borg warner shaft speed sensor son I can keep an eye on its speed. Gated at 28-psi it turns about 105,000rpm. Its got about 12,000 miles on it now and flat out rips. Quick spool and tows incredible. But I guarantee if I let the boost go a little higher the shaft will break. I love my EFR but they just don't hold up on diesels very well. Maybe look into a 64.5fmw/70 S300, that should tow/spool great and still make good power. [/QUOTE]
