Turbo Spool

[projectxspeed]

How can you tell when a turbo at X size will start spooling, and when will it hit max boost?

 

[NotUrAverage_Si]

What size turbo are you specifically talking about?

I was looking for general info. How to tell when a turbo would start spooling and when it would hit full boost like: t24 or t3/t4e

It depends on the engine. A turbo is a flow-powered device. The more the engine feeds it, the faster it will spin to feed the engine. The spool is not linear.

Could you give me a ball park estimate about a b18b with a complete stock setup?

depends man...

air flow depicts its spool characteristics...

how much air is being moved- intake, valves, head flow, manifolds, exhausts, etc all factor in to it- as does compression, displacement, timing.

Alright thats an honest answer. It sounds like I've got a lot of reading in my future. Where can I find the information about engine behavior? More specifically like websites, and books.
