Tell me about a turbo of this size, turbine AR of .48 and a compressor trim of 60. Is this gonna be laggy? Its going to be put on a prelude h22. I heard two different things. The smaller the compressor housing is the faster the spool up, and i heard the bigger it is the faster the spool up. I would go to think it would be the smaller it is. help me out!
Thanks you guys are helpful

It's the exhaust side of the turbo that really controls spooling.

Smaller= faster spool but more exhaust restriction.

well, if thats the case stretch.. couldnt u have a small housing with a large A/R

so no its not how small the housing is. its what the A/R is, and trim..

Sorry about the generalized statement.

Thanks for clearing that up.

I was referring to the A/R. Even though he used the word "housing".

Isn't it true that the smaller the A/R you have, the faster the spool-up and more resrtiction you get? (generally speaking of course)
