Damn, that blade looks like metal and engineering art.
Just to make sure..
CTR4X 68/71 is on the website, this is rated at a max of 1250hp. Jesus that's more than the old 7675 at 1150hp.
The 6871 hubless will do more than 1250hp
Their ratings are conservative.
they want guys to be happily surprised

Sam's turbo will be 1350+hp capable.
The last 6971 ctr non hubless i did made 1200hp on a 3 bolt .85 on a buick and spooled in under.5 of a sec.
If that ramp is chosen

That's off the footbrake
Backpressure was high though with a 3 bolt it was all in.
The 4 bolt would have made 100hp more.
Looking at the data on say a 6771 ctr triple bb on a 3 bolt we saw 990 hp at 1.8 bp with a 3 bolt.
That turbo was not all in it

Ctrx is 15% more flow mm for mm
At 1000hp that's 150hp on tap and get this with faster spool

That's why undersizing which has worked in the past is not needed now with these new turbos

That allows flexibility in turbo ramps never before seen.
And footbrake power that is unmatched.
