                  strange,are the exhaust pressures not going to work like backpressure against crankcase pressure are will it work like a vacuum that sucks crankcase pressure into the exhaust?

                        At the Moment i have just a small timeframe for my car[emoji19] . I have to help my friends with there cars...

                        Beginning with the fuelpumps.

                        From Tank to catchtank with Aeromotive a2000 and with Aeromotive pro Serie to fuelrail[emoji41]. So this should be enough fuel for 2500hp

                          Nice work but that is not the ideal place for water return or water feed...

                          Heat rises. Ideally:
                          - coolant feed = block
                          - coolant return = rear of water pump , so anywhere along the thermostat bypass pipe. When engine is running coolant is pushed through the block into the turbocharger and PULLED by the water pump from the turbocharger. In your scenario , coolant is just being pushed from the block into the turbocharger which is the same as being pushed from the cylinder head so you are not creating an ideal loop.

                            Coolant flows from block to head. Why it should not circulate?

                              Surely coolant temperature is highest in the head where most heat is transferred?

                                How is it circulating?
                                You have removed / bypassed the system needed to pull it back through the block via the water pump. The key word in that term is pump i.e. it pulls liquid/fluid from one region and pushes /pumps it through to another region.

                                By having a feed in the block and then having the return in the cylinder head , you are not doing anything as it is the same system - feed. You need to focus on the return.

                                There is a reason alot of enthusiasts/amateurs fry CHRA's in turbochargers and that is due to in-properly routing coolant feed & return lines.

                                Get the return on the pipe running along the side of the block from the back of the water pump and you are golden.
