G'day, I have a Garrett GT3782 that is percuilar because the turbine AR is .99 where every other GT3782 is 1.something. I am glad of the smaller number as it is going to be used on a 245 hemi (why not a 265 everyone says, because I wan't to fit into a particular class-why not lie, everyone than says!). It is originally of a Scania bus and is part number 703013-8 and cust/model number 1412936 and/or 1524885. I cannot find this turbo in any records. I got it on the basis/flow etc of the usual GT3782. I figure the smaller A/R number will give/need a little less flow? through the turbine. The 245 has to hang together for long runs across the dry salt lakes next march, oh and on the street, so don't really want much more than 6500rpm. It is built strongly but is still a push rod old tech motor. If anyone knows anything, I would like to know so I could get a graph idea and just out of curiosity. Thanks Julian.
