Daniel's PTE 6870 TEASER 807whp and plenty to go

The thing I didn't expect is how well the 6870 seems to spool, definitely seems like it'd outclass the Super99 in terms of spool - guess it depends how much, if any extra power capability the Super99 might have is worth it?
Thank you for sharing as always

On compressor covers that dont have the option it adds more cost compared to one like the EFR. Not having a compressor map or max rpm rating for a given turbo as part of its sales information makes shaft speed cool but not very useful. If I had the info for max shaft speed or backpressure vs max hp, of the 2 options I only need backpressure to know when the turbo is done or needs a larger housing.
If Precision shared more information then shaft speed would be more relevant, but alas they chose to keep those to themselves. It's like tuning a car by AFR/IDC only and guessing when the fuel pressure drops. I can see when my map is okay and when it starts to go weird. Its nice to know exactly where it is but I dont have to see the data to know I am out of pump.

nice results and interesting discussion. powerband is reminiscent of martin's 9180 setup, but iirc, his was at 40 psi for 850 whp. granted that his motor is a 2.4L along with a few other differences, but can't help but wonder how these two turbos would compare for overall "asskicking" potential.

I am a bit more of a FP than Precision fanboi, but I am still an eternal realist and the majority of the results seem to suggest the 6870 will have the overall balance in it's favour - though I don't know of anyone YET testing the Super94 HTZ so there could be something in that.

They don't have a log of my car in 4th. Only 3rd gear of mine and my car spools faster than Akash's old car.
