Hey Gang,
I got lots of comments about the Project LS400T intercooler. The intercooler is 3.5" x 11.5" x 36". Part of the intercool gets fresh air from the lower bumper and upper half is blocked by the front bumper. This is an issue when we think of the air dynamics for cooling. However, since i need more cooling for the FI system. I utilized the A/C for cooling too. The A/C fans are not very effecient in cooling the radiator. However, the upper portion of the intercooler and the lower portion of the fans are about 1" about.
When the A/C fans are on, they act as dual fans pulling air to cool the upper part of the intercooler. This is quite an interesting idea and works great. After driving for about 30 minutes, i place my hand on the intercooler. One hand on the right and one hand one the left. The right hand part of the intercooler (closer to the turbo) felt warm and the left side felt cool.
In order to active those A/C fans, i have changed the water temperature sensor from 199 degree F (dealer price is $58 and its compatible with Toyota cars at similar years) to 160. However, Toyota or Lexus does not have temperature sensor rated at 160 F. Few after market sensor like Wells (part # SW517 ($29.99)) offers 193 F.
Talked to my friend about this issue. He recommend this glue on temperature sensor ($40). Its about the size of a penny and super glue it into the radiator or any area where temperature can be sense. I use super glue initially to hold it into the side of the radiator and later I used JB Weld glue.
The sensor get ground from the frame and the other line goes to a negative wire of a relay. The cooling system now is activated at 160 F and off at 150. Here are some pictures.
