I ordered Evolution Raceworks side mount intercoolers yesterday. I was divided between those or a front mount. FMIC kits are cheaper and have yielded better results, but I didn’t want to deal with cutting everything up to mount it and then not have things fit well and deal with more boost leaks.
I am currently running RS4 intercoolers and further cooling the charge with water/meth. The IATs hover about 20* over ambient and I know they can be lower.
Conveniently, my friend Brad with a K04′d S4 just had ERs installed along with a fueling kit and tune for e85. Last week we met up and ran some logs.
Here’s a plot of the two setups:
I talked to someone in Canada with the same Vast 93+meth tune, but with ERs. He said his IATs hover around ambient, so I’m hoping that’s where I end up.
For kicks, here’s a plot of 4 setups. Brad’s stock SMIC car on K04s, my stage2+ car on just RS4 SMICs, my current RS4+meth setup and Brad’s current ER setup. Soon I’ll add a ER+meth plot
Today was rear wheel bearing day. I almost stripped the axle bolt but managed to break it free by slipping a box end wrench over the 14mm socket. The rest of the suspension was a challenge, but with a hammer and an air chisel it came apart. I took the knuckle to my friend Darrel’s shop to use his press. I almost ruined the new bearing when I pressed the hub in without supporting the bearing from the bottom. Oops. It went back together very smoothly though.
After that I plumbed the meth up and installed the new coolant tank. Then realized I didn’t have enough G12
