Before and after upgrading the compressor wheels on my K24's...(edited)

This is on my 993tt.
Running 1.1 bar before
Running 1.2 bar after

The only difference is the super 60 compressor wheel from the stock K24.

This should get some wheels turning for you guys to look at other compressor wheel choices than the KKK series. The Garrett series are high pressure wheels vs the KKK low pressure wheels.

FWIW the upgrade cost me $600.00 total.

which colors are what? can't read the description.

Amazing difference in power. Was that 1.2 bar before and after? Super rich mix too.

Red is after Blue is before...The before HP curve overlays the after torque
 

curve making it a little difficult to read.

in that case, wow, nice top end kick and flatter torque curve...

Yes same before and after...I am working on fixing the fuel curve.

Now you just need more boost between 4500-5500rpm, so you can really take advantage of it.

getting a little lean up top on the new wheel it seems

when your mod's torque curve is identical to the baseline's hp curve..
 

you know you have a winnar

I am out of injector. New ones on the way.
 

So for now I only run 1.1 bar (509whp)
