I see normal HD wastegate, but by chance do you have the oversized RJC Puck? Actually the problems I've encountered with the oversized puck have been the opposite. Can't get enough closed pressure over wastegate port to get enough boost, or control it steadily because center of pivot point to center of puck is 1.25". Stock center point is 1". The stock arm connected to puck shaft is also 1" from center to center. The RJC oversized puck comes with stock length arm throwing off the geometry, and actuator doesn't have enough leverage to hold puck closed. Multiple people have made RJC aware of this issue, but the response is oh I've never heard someone have that issue before. Sorry for the rant. Probably not relevant to your issue. Did you ever get it figured out? Has the wastegate hole been opened to match the puck size?
I dont believe its Jason's fault interesting theory
Here is the proven science with built motors that move air fast.
There isnt enough pressure to keep the puck closed and the wastegate size may be not what the combo needs
there is a good amount of backpressure to bring up boost that quickly with a 64 billet bb turbo and the puck also may need more than just that probably 40 year spring and a small wastegate hole
yes even if you enlarge it.
different behavior among these internally dumped wastegates happen due to what the car is doing in terms of the combo
The 64 turbo lites up fast
I've seen them hit full boost in .03 secs
You really think a a small internal gate with a 18lb spring is going to control boost regardless of puck angle?
That may save you a hundredth of a sec before it blows open
the external gates are much larger to get the flow out of the gate to control boost the pressure which can be speciffically added with co2
Boost creep
Blowing the gate open
Not getting the boost low enough or high enough
All indicators of the wastegate not doing its job
