Gate idea

[hondarider552]

Not my idea, heard it from someone here, but not sure if it would work..

Since my 75 pedestal is not gate ready, either I get a new RDL unit, or this:

LB7/LLY passenger side up pipe with EGR provision..

Brace the EGR rider pipe (like you can do in EGR delete)

Connect the riser pipe to inlet of gate.

outlet of gate routed to fenderwell sort of like PPE Dan's..

Thoughts?

That would only release pressure from that one side right?

Or have the housing machined to accept a gate.

If your ped wasn't so tall you could run a spacer between ped and charger with an oval port out the side

yeah it would only gate from one side, which would still slow the turbo, but would create a serious imbalance from the left to right bank.

Who can do this Evan? I could go that route.

Talk to danville they had pics of stock housings they did. I talked with Trent about having it done to my s475 when it was a single but never I never did.

Hsp ped ftw

It will work.

I have thought about doing this, but i was going to cut a hole and weld the waste gate tube onto the turbine housing. The only thing that might be problematic is if welding will crack the turbine housing.

I found a picture of what i was thinking, you can make it easy to route it out where ever you want it.

Like this Bri?

 

[hondarider552]

Have one that fits a 83mm turbine mark?

 

[MarkBroviak]

Yeap, just tell me the a/r you want and I will build one for you.

 

[hondarider552]

That will work. I will in contact. thanks!

I don't think it would be too unbalanced. Dumping off one side would have lower DP and flow into the turbo, which would make the ungated bank flow better. It would be unbalanced but not too bad. Now gating it downstream of where the flows join is still much more ideal.

 

[SSchmi5519]

If its a divided housing the sides don't join until they hit the wheel in the turbine.

Good point.
It does look like the danville setup may tap both runners or sides.
I think my crank broke because of imbalance in backpressue.
I was gated off of the egr port on a twin setup at the time.

I don't think that 100psi of drive (which is a lot imo), is anything substantial for the piston to push against on exh stroke compared to cyl pressure on the compression stroke.

 

[SSchmi5519]

Cyl pressures can stretch near 3500-4000 psi for reference.
