Garrett SFI 61.1 Turbo

Garrett By Honeywell Performance Aftermarket division has created a range of new SFI 61.1 Spec turbochargers for use in accordance to new rules governing many of the North American Drag Race sanctioning bodies. Based on the Garrett GT55R and GTX55R turbochargers, the new SFI 61.1 Spec turbos meets all requirements for the NHRA Pro Modified Class as well as those for the American Drag Racing League (ADRL), the Xtreme-Drag Racing League (X-DRL) and all others that require the SFI 61.1 spec. The new turbochargers give racers a choice of bolted inlet flange turbine housings available stainless v-band inlet flange turbine housings. The stainless steel v-band inlet housings offer a 10-pound weight savings over the bolted inlets while the smaller A/R bolted inlet housings carry on the traditional turbine inlet design. Conversion services are available; please see the below instructions to see how to send in your current GT55R / GTX55R Turbochargers for SFI certification.
