PTE SCM 50 cut exhaust housing question

[B00STED4banger]

I just ordered a pte SCM 50 from extreme PSI, i ordered the cut exhaust housing and wanted to know if anybody had this done, and how bad it hurts the flow and power output of the turbo . also i got the .48 and 76trim wheels Any response would be great

If you have a week or so I'll be able to answer your questions. I bought the PTE GT-32E from DSMotorsports and it's internally gated and also has the cut exhaust housing. It will be installed Aug 4th at TurboTrix and then Dyno'ed so I'll see what gains I get over my Big16G Dyno charts.

yeah post up your numbers, i would love to see the differecne as i am coming from a b16g also. I will not even have mine for a week or so. Good luck on the install and dyno run

Just for your info.
There really isn't any reason to get the cut housing.
I held 15-16psi with no creep at all.
I know you want to hear from someone that has the cut housing but hopefully this will help others contemplating this.

Good luck

I understand what you're saying VBGSX. I ran 13.9 at 20psi no creep with my Big16G and 3" RNR O2 eliminator downpipe and 3" cat back. I just want to allow any and all un-used exhaust gases exit as quickly as possible from the new PTE turbo setup.

true about getting rid of the gasses but the theory(only theory) is that with the cut housing it actually causes turbulence, not allowing it to flow or escape properly.
The wastegate opens towards the turbine wheel. With the housing cut, it flows out the gate and runs directly into the exhaust gasses from the turbine.

On a properly ported O2 housing, it should flow better. If the wastegate tube is hogged out and smooth, it will flow well and merge nicely into the exhaust stream.
The other way would cause a lot more turbulence.

I have the SCM 50trim cut housing. 7blot ran a 12.4@110 now wth the 2.3 stroker 6bolt I ran a 11.97@ 117, so I don't think it's causing much of a concern. When I first bolted it on I could hold 8psi to redline, on the 7bolt stock motor, I tightened the actuator arm so I could run low boost at 16psi to redline. Never a problem. Just my .02
