Turbine Wheel Size

[MrStabby]

Did i buy a pair of duds?

There is a lot of clearance between the turbine wheel and the housing - the wheel just looks too small.

This looks more like what i would have expected.

did you buy stockers or hiflows or n1's ?

Unused rebuilt stockers with steel wheels. Receipt from Lavish Performance lists "2x CTW Turbine wheel", no mention of hiflowing.

[Cubes]

Doesn't look good.

[paulr33]

well arent the stockers ceramic wheelies?

put a magnet on the wheel see if its metal or not

and by rebuilt steelies were u expecting standard spec just steel wheel or rebuilt to larger steel wheels

Welcom to a world of lag if you put them on your car.

that turbo has the wrong size rear housing on it.

Thats what my GT3076 looked like when I bolted a GT3540 rear housing onto it (for fitting purposes)

[MrStabby]

that turbo has the wrong size rear housing on it.

Or to look at it another way the wheel is too small. Bugger.

Thanks all for your opinions.

[MrStabby]

Ok, in case anyone is interested; CTW is clipped turbine wheels = highflow. What the hell, i'll bang 'em on with some split dumps and see how it goes on the dyno. If the response is crappy i'll stop being a tightwad and get the N1s.

[The Mafia]

either that or get some stock rear housings and bore them to fit the wheels better.

[courier33]

The magnet on the wheels wont tell you anything because if they are inconel, they wont be magnetic

[MrStabby]

Pretty sure the housings are stock - the clipped wheels are smaller than stock, hence the gap.

[The Mafia]

cropping a turbine even smaller is a stupid way of allowing more flow

If the compressor wheels are upgraded this mod helps to eliminate surge. Probably the case.

[R34GTFOUR]

miles too small, that clearance is shocking

that would be simular to driving around with the wastegate stuck open...

How does this work?

Does it make the Turbo's laggier so that the compressors aren't pushing too much air before the engine is spinning fast enough to swallow it?

Who ever did this is not proffessional at all.

Maybe he could try this:

I don't know if you remember the old $350 turbo 250rwkw thread but, it works when you have a compressor that sits right on the surgeline with a certain amount of boost.

It works well to a point. The $350 turbo had a very impressive power curve for what it was, it's not the best way to build a turbo however.
