New to the forum, lurk around here, yellow bullet, etc regularly.
Bought a 91 hatch. 306, TFW forged rods and pistons, Anderson N41 cam, gt40 heads, ON3 turbo kit w/ 70mm turbo, 42# injectors, etc.
I've had the car 4-6 weeks, on the way home, it ran good, but started running really lean. For some reason the fuel pressure was on 24#. Got it up to 40 at the tank and 38 at the rail. Swapped the stock fuel lines to 3/8 supply and 5/16 return. Took it to my tuner, it made right at 520hp at 88% on injectors. In boost, in running around 11-11.2 AFR on my wideband, and 13.8-14.2 cruising.
As far as cooling goes, has an aluminum radiator and unsure of the fan specs, but no shroud. I am from Alabama and it has been a scorcher here the last few days. It started running hot on me (have not driven the car much at all at this point around town) sitting in a drive through weekend before last. Again, it's really hot here and I didn't think too too much of it. This past weekend, I was playing with the car a bit after getting it back from dyno, and it wanted to run hot on me around town. Speed up to 60 mph or so and it would cool down.
I am in residential construction and had to drop the car off to get subframe connectors welded in, so I drove to work, on interstate it did great. Around the subdivision it was very short stop and go all day so no time for it to run hot. Interstate to drop it off, no issues. Picked the car up and had to stop 3 times on my way home, which is roughly a 25 minute drive through town. Of course, get home and passenger window motor goes out and it's supposed to start raining. After it cooled off, took it 5-7 mins down the road to my shop, got warm but not hot. Made one decent pull in it. On my way home, starts running hot on me again.
Frustrated as hell, went to pull a part here and picked up a Taurus fan/shroud. They only had the 3.0, no 3.8 but it has to be 100x better than what I have on there now.
As far as unknowns, idk what thermostat is in the car, or if it has one. They had fan worked to a toggle switch, which I'll be changing as well. They relocated alternator to driver side, have heard they make two separate water pumps(clockwise and counter clockwise) havent pulled it to see what is on the car. Every time it has run hot (on gauge) I never hear the radiator boiling which was odd as well.
Can any of you guys shoot me some recommendations on where I should start? Frustrating having a new toy and not even able to drive the dang thing. I appreciate the help in advance.
