What do turbo size numbers mean?
Basically, the larger the number, the bigger the housing. Exhaust-gas velocity plays a major role in a turbo’s spooling (turbine wheel speed). As the exhaust volume in the housing’s volute decreases, gas is able to maintain velocity and a high energy level.
What is turbo trim size?
Trim. “Trim” is another commonly thrown-around term when discussing turbo sizing. Simply put, it’s an expression of the relationship between the inducer and exducer diameters of turbine or (more commonly) compressor wheels, and is useful for judging how much air either one can move.

What is turbo a R ratio?
Aspect Ratio (AR) is commonly used to indicate a turbocharger housing size. The Aspect Ratio (AR) is the ratio of the area of the exhaust turbine inlet to the radius from the turbine impeller center. The AR ratio should remain the same as the Volute gets smaller as it gets closer to the impeller.
What mm size is a HX35 turbo?
What is the difference between T3 and T4 turbos?
Generally speaking T3 class turbos can deliver enough air volume for applications in the 200 to 300HP range. The bigger T4 turbo has a larger turbine on the exhaust side and larger turbine fins in intake compressor side.
What is the difference between the bobcat T66 and T76?
The vertical-lift-path Bobcat® T66 enhances performance with increased lifting capabilities and improved comfort so you can do more. The vertical lift Bobcat® T76 offers optimized performance, lifting capabilities and comfort so you can do more. The vertical lift path T740 tackles your lifting and digging tasks.
What are the T numbers on a turbo?
Turbos are often referred to by “T” numbers that are really a “class type” . These numbers were originally created by Garrett, the largest turbo manufacturer in the world. You have probably heard people talking about T3 and T4 turbos in their car. The “T3” number is a general CFM classification.
How do I choose a turbo?
So the thing to keep in mind is to select a turbo that has a small enough turbine to spool up quickly, but big enough to pump enough air to support the maximum horsepower you’re targeting to achieve. That’s the tradeoff you need to consider, horsepower versus spool time. Turbos are often referred to by “T” numbers that are really a “class type” .
