After seeing all these posts about SPS 66 versus PS 62 versus HTB2 versus stock turbos I decided to compile all my dyno results with all the different turbos I've run to show the various spool up times from 100 HP to 350 HP. If I couldn't get to 350 HP I used 300 HP instead. The results are interesting, somewhat predictable, and certainly speak volumes.

See here for the data:

Thanks for posting this information.

I posted this thread to try and get a handle on running a compound set up with a II PS62/12 on top of a B2.

With an auto tranny and a goal of 600 rwhp with decent spool up, looks like compounds may still rule the roost?

Thanks again for sharing!
