I was just going to make a new post about this same setup basically.

So how does it run on 10 psi ?
And what turbo are you using ?

Have you ever boosted another motor ?
And is it comparable to the last ?

^^^^ comparision between 10:1 and 9:1 compression. Spool time was the exact same

 

Interesting.

But I couldnt care less about spool up time in my case.

But the power loss is what is scaring me a lot now.

 

LMAO , no you've just removed all doubt.

 

What bugs me is that there seems to be a boost difference between the runs, and he doesn't post data about ambient temperature, moisture, engine coolant temp and other very serious variables like that. Also would be interesting to know what fuel the car was running.
