Trans Brake 2 Step
Whats the best way to regulate boost and rpm on the trans brake? Is there a way besides having a 2 step and using a small spring in the wastegate? I can holod it at 4k rpms on the brake but the longer I sit there the boost obviously creeps up.

That's is the way I'm running mine. TH-400 with T/B. 2lb wastegate; 2-step. I can set the 2-step at an rpm that the track will hold the boost the SS makes. Most of the time our track is ****!! So I end up setting the 2-step at 3700, only makes about 3-4lbs. AND I still blow the tires off Oh yea - I am using a C02 controlled AMS-1000 to help things out.
One of these days I will be able to leave at 4500rpms on 10lbs of boost

I'm running a 10psi spring. I'm thinking if I set a 2 step at 3500rpms the longer I sit of it the higher boost will climb. Is that not the case. Since its under a load I think it would just continue to build boost without raising the rpms.
Btw what are you guys running for a catch can setup. We tapped each valve cover with -8 and ran it to a can the ran a line from the can to the intake tube in front of the turbo. It has no check valve and it seem like it might be doing worse than before. Could the inlet pipe be pressurizing the can somehow?

My catch can setup - -8 to the can from both valve covers... period. The can has a filter. Never a problem. Why would you run the lines to the "intake tube in front of the turbo?"

From doing alot of looking online alot of people ran it back to the inlet of the turbo for it to pull a vaccum on the can. You just need a well baffled can to not suck oil back into the intake. Most of them ran a check valve on the line going to the intake pipe.
