Same size AND more horses?
Our latest, large-frame, S400 has the same outside dimensions as the
tried and true S475 but is capable of supporting 150 more HP. Based on BorgWarner’s S400SX-E platform, the
ProTow 476SX-E is the perfect upgrade when you need to replace your tired S475.
The ProTow 476SX-E will be the absolute best performing low
pressure turbo in your compound kit for daily driving and towing. Pair with
your stock turbocharger, one of our modified ProMax or ProRam upgrades, or even
a small S300. You'll be ready to toss that EGT gauge in the garbage once you
realize 1300+ degree EGT's are a thing of the past...
