yeah and threw the testing we have done its all about flowing in certain areas. before i had a s366 as the big turbo. the 30r ramped up but started to wedge instead of ramping up like a wall. that had a .91 t4 housing on it. i swapped out turbos to a bigger t6 1.32 and it helped a lot. now that 30r can flow threw that t6 a lot easier. now after all that i was seeing 30psi at 5200. 30r making 19psi and the 80mm making 11psi. it still however is not what im looking for. i want a wall at 3500 that i can get 45+psi at. so we took the pipe off between turbos to see where the restriction is and its in that pipe. did one pull and was a straight wall at 3500. so i know now that there is no restriction in the exhaust side but in the cold side. so i ordered 3.5 inch piping and will go retest once i re do that pipe.
