So much to learn, not enough time to do it. Torque Management tuning. I haven't even scratched the surface of my ECU's capabilities.

Coolant pressure testing has been completed. The best setup is to change your car to a Z1 170 deg thermostat and use a Nissan 88kpa radiator cap which comes on the 2012 and up 370z's. You also need to stick with the factory pressurized or non-pressurized coolant tank. They have enough volume to hold the extra coolant to keep your levels correct. If your engine is healthy your coolant pressure should be around 15 to 17psi under max load. The pressure climbs up to around that level in the upper rpm range. When the thermostat is closed your pressure may rise up during warm up. It is perfectly normal. I hope this helps some folks get an understanding of what is going on. You want to record a baseline of what your car does. There are many variables. Where the coolant pressure sensor is, Thermostat, and what radiator cap is being used. You are looking for a change from the normal.

Can't remember if I posted this or not.

Some more.

I am figuring things out. Without the help of the Emtron and sensors, this would be very difficult to do.

It appears a few folks are starting to figure out how to build proper VQ turbo kits now days. Mr. Squeeze and I figured it out about 3 years ago. I have just had my popcorn out watching the show. Starting to see a few cars make 9xxwhp at 23psi of boost like my car does. My car could make more at 23psi of boost but I have kept my timing conservative. Only 15 to 16 degrees of timing. I want to keep the cylinder pressure in check. At 9.5:1 or 10:1 that's what they should make if the turbo kit is right with the correct size turbos.

Maybe you should phone up some shops to school them on how to produce big power on the VQ since you seem to come across as the Godfather of this topic. Might do the community some good since having more knowledge is never a bad thing.

This is why I don't post much anymore.

Yup, I saw it. I am drooling. LOL

I wonder. Hmm.
