Bleeding Weapon X Exchanger
Does anyone have tips for bleeding the Weapon X exchanger and LT4 blower?
I have air in the system somewhere and cannot seem to get it out. I have bleed the system from the WX bleed line, the supercharger fill valve and both bleeder screws on the front of the blower. Still no luck. This morning it was 67 degrees here in Houston and blower temp was 140 once I got to work (7 Miles @ approx 30 mph due to traffic). I would expect temps to have remained around 100 or less with the cool air outside. Does anyone else have temps this high? As a note I have the Weapon X front mount intercooler, LT4 blower (2.3 pulley) and the NX Lid. |

my suggestion is to get a reservoir to ensure no air pockets exist. Obviously, use their bleed line too and make certain there is a steady stream.

Using a vacuum charging tool is by far the best and easiest way to bleed the system. I was working on getting some fittings together to work with the BMW vacuum filling tool we have, but I ended up just doing a reservoir. While I haven’t replaced my heat exchangers or anything, I think it would self bleed.

1. Some have had luck with jacking the front up to make sure that the port by the blower is at the highest point.
2. You have to cycle the push button several times to draw the coolant and make sure that you get no air pulled in hence some type of way to keep coolant full above the valve and sealed. someone had a pic of a funnel taped onto the valve(since they didn't have the tool) in the funnel was full of coolant(it has to be sealed good so you dont pull air) so each time you hit the start button (do not start the car) it draws coolant in. it might take 2 people one to depress the valve down manually while 1 person pushes the button. Its better the have a quick disconnect that fits the valve with a hose and a container/funnel above plugged into the valve while filling. DO NOT LET THE FUNNEL OR CONTAINER GO DRY EVER) or it will pull air in. If you draw air in or hit a pocket the pump will stop... so once you hear it shut off or circulation stops you have to start all over again. if it stays running till the ignition times off I'd say its full with no air.

I can ask my buddy at dealer but I figure the usual snap on, Matco, for dealers.. Here is aftermarket

the vacuum tool and such is a PITA and not necessary IMHO. Use a funnel, tube, and depress the black plastic button with a long 1/4" socket extension. Keep the funnel full and run until all bubbles are gone...simple. Or get a reservoir and all of your worries are instantly gone.

My ride is LT1 with the LT4 blower (2.3 upper at approx 610whp) and I would expect much lower temps with the WX system adding additional coolant. What kind of temps can I expect out of this system? I mean this morning it is 84 degrees here in Houston and 54% humidity. I would not expect a nearly 60 degree delta between ambient and IAT2 temps. I have to get this solved or at least reassurance that somehow this temperature range is "normal" for the ZL1. I don't want to cause harm to either the blower or worse...the engine. |

That doesn’t sound right to me. I watch my IAT2s from time to time on my P3 gauge. At a steady cruise with good airflow over the heat exchangers (like a freeway drive), my IAT2s are maybe 10-15 degrees above ambient. When parking the car with a hot engine (like when going into a store for 20 minutes), it’s very normal for the temps to climb — but they should come back down to normal with some airflow. Still, I’ve never seen temps anywhere near what you’re reporting. I know it’s not nearly as hot on the California coast as it is in Houston, but we get the occasional heat wave. I’ve driven this car in 90+ degree weather, and have not experienced what you have. I’ll look at some of my logs and pay closer attention to my live readings next time I drive the car, but I definitely think there’s air in your system or something else wrong. |

My directions are easier lol..
How much are you overdriving the blower upper and lower? I've done a few runs lately with vararam intakes I have just a lower in 100 weather and high humidity I see 120s during a 3rd pull from 2000 rpm till redline. incidentally lower the fender IAT helps a ton with this new intake Im seeing a lot lower blower IATS by doing so.. less knock retard to 0, timing went from 16.X to 19.5, MAF is in low 800s compared to 900s..

That said, does an LT1 even use manifold air temp? |
