compressor wheel trim?

[nismoboy]

how do u tell what the compressor wheel trim is by looking at a turbo? thanks

[nismoboy]

so what part do u messure? to find out? which/where is the trim? cheers.

 

[nismoboy]

No one know where the compressor trim actually is?

is it the housing? or the compressor wheel its self :?: :?:

Trim? What do you mean by trim?

 

[nismoboy]

well with the compressor wheel size ie (71mm) you get a trim (ie 56 trim)
just wanted to know how u find out what trim u have?

Take it apart and measure it... Its the only way unless you have the tech stats from the supplier...

Like the A/R ratio?

Sounds like a job best left to an expert
as for dismantling a turbo :shock:

What you mean..?

The A/R is the only detail you get on the turbo really... Its on the Compressor Housing...

Some turbo's may have the tech data on the manufacturers tag which is on the turbo somewhere... TD ones won't though...

Just asking is that what he means by "trim"? Does he mean A/R? Im not 100% clued up on turbos either - there is a lot to learn.

why do you what to check comp trim? what trim do you have at the mo? having larger trim on same size wheel will not see an bhp increase.(not that you,ll notice)

i think u`ll find it will

 

[DOT2DOT]

Ah i think ive got this. The trim is the angle of the blades on the comp? Is that right?

is it the housing? or the compressor wheel its self :?: :?:

The trim is the width of the blades on the compressor wheel, the inducer part of the compressor turbine (the bit you can see) relative to the outer tip diameter.

For example if you gat a hybrid turbo it may have a standard compressor housing that has been machined out to allow fitting of a compressor wheel with a larger trim, but same diameter.

You can work out a compressor wheels trim by dividing the diameter of the inducer (small end) by the diameter of the outer tip (big end) then squaring..... so you will have to take the compressor housing off to do this.

At last!! someone who actually knows lol. Thanks mate

it would have helped if i knew what part to measure :roll:
