TST CR Dyno Graph

[DavidTD]

I'll try to post a couple of graphs later but I have a question for those that have run on a dyno with the TST PMCR.



So far I have only put two PMCR's on the dyno and both had the same HP/TQ curves. What was odd was that both lines on both trucks peak towards the end of the runs. It's like the ECM is defueling until near the end of the run, then it lets it fly high.



What is everyone else seeing on their graphs? Without owning one to run some test on, I am having to "guess" what is happening here. Any ideas?



Power? Man this is a sweet box and Mark Chapple deserves many cudos for this one.



Thanks,

tighten the wastegate and it will peak earlier



but not too much you can blow stuff up

 

[Agades]

whats amaizing is theres so much energy pushing the turbine that you can still build a lot of boost even if the wastegate opens at 22 psi, but it wont happen till the latter part of the rpms



with the stock elbow I lost a lot of mid range power

but peaked at high rpm

David; maybe the clutch is slipping some, I think mine was..... Ray

Ray,



Jerry's truck had a Suncoast unit in it. No slippage there for sure. This looks more like electronic defueling to me on the graph. Both torque and HP peak way up top...
