Hey all, I am going to be getting a turbo for my car (switching from an N/A). This will need to fill in some very specific needs. So could someone please explain the different specs of turbos or a place that would explain them. Cuz right now I am looking at Garrett's web site and all the little things they have listed (Airflow charts, pressure ratio charts, trim numbers, A/R numbers etc...)
I am sorry if this is stupid, but I am having trouble finding info on this.

 

Post your goals for HP, boost, whatnot. then

If your looking for general knoledge.
Buy Corky Bells book. Boosted, guided to design, testing and istalling turbocharging systems.

great book

 

My goal is 250hp at the wheels, and I want minumal spool up cuz this is going to be for backroads/autox/and road corses(sp).
I have been looking at a garret GT22 (specs are here http://www.turbobygarrett.com/turbo.../jsp/index.jsp# ) I would also like to see what makes a TR30R as this is the turgo that the rally guys use and they need instant response.

 

Well here is the specs on that GT22 turbo
