Would I only spool it if I ran it as a compound turbo set up? right now my motor is at 10:1 compression IIRC rb25DE with 60k miles and fresh oem hg and other gaskets.
Yes. It's big!
what RPM would an rb25 spool this?

Is this realistic? I have a holset ht60 that I was going to put on my ls1 trans am. It should flow enough for 700-800 rwhp. its T6 frame. its 74mm compressor, 22cm twin scroll turbine housing. I was thinking of using a quick spool valve.

Re: what RPM would an rb25 spool this?
whats the point if your running a rb25 you are good to about 450whp with a good tune and a gt3076r I would never run a holset on any of my cars ya they make crazy boost and all but you have to use desial WGA and all too. Well you DON"T HAVE TO but they fry every other one i have come to work on but idk maybe its just me but i have seen thoes turbos BLOW APART motors so idk

Re: what RPM would an rb25 spool this?
and to answer your question it depends on how much boost you were actually running

Re: what RPM would an rb25 spool this?
I would do some searching in the RB forum, But I bet you wouldn't start making boost untill 4Kish, and maybe make good power at 6K or so.
A stock DET would rev out to 7800 with out too much trouble, but the DE has weaker valve springs.
You'd need a built motor of any degree to use that for more then taking up space in your engine bay.
----I just looked it up, and if you could max that turbo out its a 1200HP turbo on a gas engine. What is your Goal? A NA RB25DE could hold at 350RWHP, and RB25DET's can hold 550RWHP indefinitely but your going to need a build motor to use the HT60.
