Hey,

Has anyone any real experience with the aftermarket compressorwheels for the gtx35?

Do they really spool faster and have better airflow?

Currently got an gtx3576 that im going to upgrade to a gtx3582 and want the best possible wheel.

 

Go with the FP HTA3582, you can't go wrong with FP

 

the gtx3576 is very nearly equal to fp hta3582.
the gtx has 58mm compressor wheel. the hta has 59mm. wouldnt be much difference.
the gtx3582 has 62.4mm compressor.
standard 35r is 61.4mm

 

Oh I just noticed that... So FP take the normal GT3582 and alter the compressor wheel on that? I just did a quick comparison and there doesn't seem to be much difference between them. So.. what do FP actually do..

 

Completely different compressor wheel - same as GT versus GTX. The FP's version only provides a bit of a flow improvement over the normal GT3582R but a lot better spool, or a reasonable flow improvement over a GTX3576R with similar response.

The GTX3582R is a stout beast - definitely much more lag than the HTA3582 but then also a good amount more flow

 

The GTX3582R is a 73lb a min turbo. I've seen one recently make 730+ awhp on a 2.3 dsm. It pretty much made power from 4300-8000 like a champ.

 

gt35r 63lb
gtx3576 66lb
hta3582 67lb
gtx3582 75lb have seen two people hit 800whp dynojet

 

Im looking to upgrade the one i have, to an 62+mm compressor. What is the best? The titanium ones are stronger but heavier and i would like to keep as much spool as possible, and get as much air as possible. 79 pounds at 2.2 bar with great spool is my wish.

 

I would disagree slightly.

The GTX3576R may have a 58mm inducer, but only has a 76.6 exducer vs. the GT3582HTA which still has 82mm exducer. that additional rotational inertia given for that compressor wheel does indeed change behavior in the midrange, more than the HTA. Top end power, the GTX3576R takes a few more psi to do the same thing, but is limited to about 650whp while the HTA is a bit more effective than that if the goal is to reach upper end power..

I have both, and yeah, there's a difference alright. but mainly for circuit use.

 

I think the whole Titanium argument doesn't hold as much merit to the use as needed. All one has to do is get a higher grade aluminum in a T5 or T6 7075 grade to get the desired additional inertia one is looking for.. Or, even simply changing the overall exducer size would do better than worrying about using a titanium exhaust wheel.

In your case, there is no "best" as there are a lot of options out there, but I'd stay with the Garrett-based companies for best integration for the need.

 

Is the gtx3582r bigger then fp red ball bearing? How much?

 

This is a compare I put together a while back incase it helps any of you. If you find something is off lmk and I will make a note of it.
