the retardedness doesn't end. I see it is handed down, generation to generation.

did you not see my post saying my car runs too cool with just two 1/8" holes?
if you have an efficient radiator and you do the coolant reroute you are gonna have problems running with no t-stat. your car will stay in warm up enrichment mode and dump fuel. there is no reason you can't get that car running at a suitable temperature with the mods we've laid out

Paul, I completely am on your side, my father on the other hand doesnt seem to want to have a tstat at all, ive tried to tell him we need one, but he said he doesnt care, hes not putting one in.. we arent buying new fans but we have the 2 stock ones running constantly together.

dude.. the two heater hoses are going inside the firewall in the pic. My question is where are they in the cabin I'm sure there is a heater core or someshit.

good place to look is in a miata manual, gives complete diagrams of the car... also if you go to pauls homepage and click on the 94 miata coolant re-route it shows a diagram of the 1.8L's cooling system, before and after he did his re-route

as long as its 160* outside you'll be fine. I go to a track that's full of rich people who pay people to torque wheel lugs because they don't know how. You're in this group.

First of all hustler, your a DA. i do all the work myself, and or with my father. I have been working on cars, dirtbikes, motorcycles, go karts, pretty much anything with a motor since i was born. so dont tell me im one that just sits around twiddling my thumbs watching someone do the work for me. and your a DA, the coolant temp needs to be 160 for the tstat to open, not the outside air. even if it was... the tar on the track is over 100 degrees on a 75-80 degree day. and that heat just radiates up. so think before you trash someone.

track temp isn't going to be that high, and you're going to be fucked in the spring and fall, especially in your part of the world. Running no t-stat is fine if its hot enough outside. If its cooler than 80, and you have a big rad, I doubt its going to be warm enough.

most of my track days are in the summer, i dont really run it on the street. i have 2 races this year in the fall. Currently every single race ive been to.. i raced in 50 degree weather, i overheat in 10 minutes of hot laps, i have an aftermarket dual core alluminum rad. i removed the tstat, and its better, but it pegs over in 15 min. no matter what right now.

I was trying to explain this to someone else yesterday, for some reason these cars love to overheat on the track. Have you sealed off the radiator, and done big fans with a big shroud? I'm trying to avoid an extraction hood, but I think its inevitable.

I've seen 99-2000 cars to overheat with a 52mm koyo when naturally aspirated in 95* heat last summer. Sealing off the mouth of the car is going to help cooling more than anything else, but the reroute is necessary.

what radiator do you run?

I've been thinking about running a big *** vent in the hood, and ducting out the radiator like a proper gt car.

i have the front air duct sealed air tight, i dont know what model rad i have, and im running stock fans in parallel, i want new fans, but at speed they wont make any difference, or little.. i sealed the fans in so the air has to pass through them

removing the t-stat entirely WILL make the car have heat problems unless you have rerouted the coolant lines like me.

explanation: with the t-stat removed there is no restriction on the front outlet to the radiator. that makes the coolant not flow through though the block and exit the rear. it's that path of least resistance thing. so you will end up with really high temps in the rear of the engine, cylinders 3 and especially 4.

if you insist of running no t-stat you should just remove the plug part of it and leave the rest so there is some restriction so you get some flow out that back of the head too.

this may sound like a moronic question but look who i am dealing with:

are the fans flowing in the proper direction? toward engine, not toward radiator.

it's been known to happen. my daily driver 94 was like that when i bought it.
