I am going to run the heat exchanger under the rear of the car. I did mock up this weekend (rained all weekend). Where the stock muffler sat sideways is where the heat exchange will sit. I am going to use the hole/cap that is in the trunk to run the water lines through. I have 2 9in fans that I will run to help cool the heat exchanger. Anyone suggestion on whether to run the fans as a pull or push and do I force the air up towards the bottom of the car or down towards the ground? Please explain thought process.
I need to pull a lot of fuel out, but the car ran pretty good considering it was running 10afr lol I thought v2 would get me a good running tune
Edit: (seeing how the car has a evo8 maf and 550cc evo injectors. I changed my global fuel and the maf to a 2g with the evo setting, but apparently I need to do a lot more playing with it). I didn't have time and as you are about to read I didn't have a thermostat to allow the car to get above 180F until my last drive around the neighborhood.
So I got some temperature reading this past weekend + last weekend on the colt and on my buddies stock 1g.
Here is what I found:
On a 90F day (happens for like 2 weeks here in the Midwest a year) the stock 1g got up to 225F. This was after running around town and letting the car idle for like 5 min. Keep in mind, he only has the stock radiator fan and no ac fan. The fan is set on a switch that he leaves on when driving around. Read at the ECU
On a 75F day the stock 1g got up to 210F and sat there all day doing the same process. Read at the ECU
My colt with the dual core honda radiator would climb above 230 with NO THERMOSTAT if I gave it a chance on a 90F day when at idle and both the 10in and 9in fan running. Read at the ECU and on gauge with the sensor next to the ecu sensor.
On 70F day with the 88 scirocco 1.8L radiator with a 10in pull and 9in push on opposite sides with NO THERMOSTAT I drove the car for 10min and heat soaked the engine. I got the car to run at 180F. I flick the radiator fans switch off and the temperatures went up to 200F and I hit the switch for the fans and the temperature went down to 193F after 2mins. I am happy with the scirocco radiator. the one I got would have been nicer if it was not as wide by an 1inch.
What radiator hose are people using for the scirocco radiator? I am mainly concern with the lower radiator hose as my shift lever arm is hitting the hose currently when in 2nd, 4th and R.???????
In other news, I am working up a game plan for MOD. I was hoping to take more toys and even the colt, but we will see.
Also, who would have thought on 195/55/r14 with 25% tread that I would spin 1 wheel at 3psi lol. The female got a good laugh from it but was very please by the pull it gave at 7psi. She followed it by asking, "Is this why we need ......um ....drag tires. lol She was trying to think of drag radial.
EDIT: Sept 22 I ran the car at idle for like 20min trying to lean the fuel out and to see with the new 180F thermostat if the car would overheat. I have good news the car doesn't overheat, but was on a mid 70F day.
Bad news is the afr are not responding to the adjustments like I would think. Can I tune the car without a o2 signal back to the ecu? I have a lc-1 wideband but not having it simulate the narrow back to the ecu. I assume not and the ecu just dumps fuel??? I will get some readings tomorrow when I work on the car.
