This company has been a manufacturer of many components for Borg Warner in the US. They had started a performance turbo division on their own some time ago. The CompR turbo's are their own 100% construction, with advanced compressor wheel designs (ETT or extended tip technology pioneered by BW).
I went with them for a few reasons: they are local to me, make a great product, and I have seen them in action by a couple of very large engine builders here.
I replaced the T-72 with their S364 turbo for Nats. Running 13#, I netted a 12.13. When I got back, I replaced it with their new CompR62. This turbo flows almost 70#/min, and has made over 700whp (at 34#) on a single-turbo 5.3L Silverado. The reason for going to a turbo of this size (similar to a 35R) was for its streetability. The turbo comes alive almost instantly, with real nice power. If you like, you can ask Harmon his thoughts on the turbo - he's running the same one on his Sy.
If you have any questions about the turbo...call David or Bill at Bullseye Power (231-571-8424).
