Good idea thanks

What kind of readings/pressure are you seeing? Does the pressure rise significantly when accelerating due to water pump speed increase?

Thanks but is it recommended to install the sensor on the block side below the t-stat or above it on the housing upper radiator side?

Yeah thanks I’m starting to think that my coolant issue is just that I’m pushing it too far on 93 and lifting the head. So if I see this coolant does this mean my head gasket is already smoked? However, I have no other coolant issues or...

Does anyone know if 26-29 lb boost is too much for 93 octane?

I pressurized my cooling system to about 20psi and nothing. I did leak down and nothing. This sucks

Thanks for the insight

I didn’t give the machinist specific instructions for an MLS gasket I honestly didn’t know there was a difference in the process

i see, however 30 psi is just closed loop boost control on 93. The car is E85 ready just not today. The idea is to run way more than 30psi. I’m just not sure what’s going on here with that coolant spray. The head and block were recently machined.

So after a test pull on the street @ 26-30 Psi to 7000 RPM 43db knock (Haltech elite) on 93 I noticed evidence of coolant on the transfer pipe which looks to be coming from the water/pump o-ring to pipe connection. (See photo). I’m not sure if I...

popping the hood..just responding to the post title..
