We have a Buick GN with the 9569S that is knocking on 900 whp through a TH400 and a 9". I always try to under rate or "cushion" my power number quotes...its always easier to deal with a customer that is making more power than expected ;) -Reed
We are seeing all kinds of propaganda/marketing pushing "cool, new, shiny" stuff to sell new parts/inventory. Garrett thankfully has maps to compare new 10 blade compressors to 7+7. The skew in the compressor maps are clear. No free lunch. It would be great if you could share the plus/minus with folks
I will go down the rabbit hole of compressor maps soon...but the simple truth is any blade count/splitter arrangement can be tailored to perform at any reasonable PR, but like you say...there is no free lunch. Not for Garrett, Borg, Holset or any other manufacturer. You will simply move the numbers around, so choosing based off of your engine's requirement will always be in your best interest. Be ready...its coming as fast as I can wrap up the test and editing. Reed
Hi, Norb! I would need to see what we could work up for an internal gate to suit the 4.3. The rotor group would be a good match for this application. There is even a possible T3 foot so it would bolt to your existing manifold or headers. I can also upgrade your stock MHI turbo as well :) Drop me an email for details! Hope all is well up in Canada! -Reed
Yessir...the move over into XRE compressor technology has been a solid move for them HTA/HTZ has long since run its course! The HTA dates back to the very late 90's, being derived off of a K31 borgwarner wheel. It is almost a carbon copy of that technology. Reed
