Welp, two replies two different answers lol. I’m just looking for a reliable set up I’m not looking to replace turbos every 20k.

Both will make 500whp easily. If you think you may get the itch to crank up the boost in the future, go with the High Flow to leave some headroom for future enjoyment

Yes, but keep in mind its NOT that simple. Crank up the boost as you say.....supporting mods and fuel is a hurdle that has to be crossed b4 more boost can be achieved.

Hi flow for sure! Honestly not even a question in my opinion. Our shop has installed tons of upgraded turbos from all the vendors and ive never heard any of them say "I wish I had gotten smaller turbos" but have DEFINITELY heard them say "I wish I had gone for the bigger ones" a few months down the road when they want more power. Just my .02c!

Could you please share your thoughts on these:
a) what are the main differences in DD vs high flow version?
b) if reliability at 500whp is main concern which version you would recommend?
thanks!

We don't post specs. All custom Pure spec wheels. Both are equally reliable at 500whp. If that's the power level you're shooting for, definitely go with the DD! There are many dyno sheets out there with the DD turbos, making up to 600whp. So 500whp will be easy with those! As for spool, you can see Terry has even the high flow turbos spooling at ~3k rpm at his last dyno, so both spool very well.

You should do a search. This has been discussed b4. There is no straight answer. People have slipped at 400whp some not until 600whp +. Just as people have blown motors at 400whp +, yet others have done 650 to the wheels on stock internals still.

I think the best plan for an auto is:

a) upgrade the internals with new valve bodies, zip kit, fluid, etc.
b) XHP TCU flash
c) keep whp under 600 most of the time
d) start saving for when, not if, the auto starts slipping - could be 50K mi, could be 500 mi, varies based on a lot of factors, but the above measures will make it as strong as possible without a full rebuild.
