1. Intake Exhaust Turbochargers
SESS-AUTOMOTIVE

2. Intake
Cold, fresh air is best…. Like us

3. Intake
Cold air
Flow

4. Exhaust Takes exhaust away from the exhaust port (cylinder head)
Takes away super heated gasses, noise, vibration and heat

5. Exhaust Manifold Collects Exhaust Gasses from each exhaust port
Flow (restriction)
Better design = Header (better Flow)

6. Headers VS Exhaust
Better Flow
Polished
Expensive

7. Turbocharger Air + fuel = Boom
Lots of air = lots of fuel= really big boom

8. Turbocharger Gives better performance to an engine (Boost)
Creates pressure behind air for intake

9. Attached to exhaust
Harnesses pressure

10. The turbo “spools”

13. Boost Air is pressurised and compacted inside the cylinder
The degree to how much pressure or “boost” is happening is measures in PSI
Pounds per square inch

14. Intercooler
Cools the air, like blowing on hot soup

15. Engine?

16. Engine?

17. Issues To get boost, the engine must be creating exhaust pressure.
The engine must wait until exhaust gasses are fast enough to move the fans of the turbo charger
“spool the turbo”
Therefore, the engine must wait to receive boost
This is called turbo lag

18. Issues What happens when at full throttle (max boost) you let off?
Max boost pressure with nowhere to go!
Options
Turbo system pipes blow
Incorporate a valve to release the excess pressure

19. Blow off valve -BOV A valve that releases excessive boost air
