mercracing aftercooler should be here next week.. what coolant you guys using it will worth getting water wetter or waterless coolant just for cooler?
finally got aftercooler from mercracing 3 months..
didnt get my t1 sensor i ordered so im having to use stock manifold sensor location.. and using genuine honda sensor like bellow.. but gonna cut it and expose slight resistor for faster response..
i have space under the cooler for sensor but i think this will be a better location.. don't fancy making a hole in the runners
what set up are you going to run?
The dc5r crank pulley is 5.4in diameter right? I'll be running a similar setup on my new k20a but i am swapping to a larger k20a2 5.8in diameter crank pulley with a 3in boost pulley. Im looking for 11-12 psi @ 8800-9000rpm redline at 17000-17300rpm on the blower at redline. How high are you revving your jdm k20a?

We get the k20a2/ k20z1/k20z3 here... but i am picking up a jdm k20a complete swap- identical motor as you have. I am looking to set the redline to 8800-9000 depending where it stops making power. After calculating the blower rpm at redline- i figure at max, 9000rpm redline, with a 3in blower pulley I'll be right at 17300rpm at the blower- which is about 3-400 rpm below what the blower porter recommends as max safe working rpm. Im not taking any chances this time around after the blower blew up the first time lol
