lowest safe operating temp?

[neverlift]

I was running a gutted thermostat to compensate for a fuct radiator, installed an sr 2row today and it will not go much over 150, I mean when I go in a store and come out it will go to 160 for a brief second. Am I gonna hurt anything?

Dont get me wrong I dont mind the low temp, just want to make sure.

next on the list is ac

[lrb_2000]

I like to keep mine around 170.. it doesn't go much higher, even right now in the summer.. 150 seems kinda low, what is your oil temp? I usually go off that more than water temp.

[neverlift]

yeah I don't have one yet, I know my turbo feed cooler is a hair or two cooler seriously instead of it burning me it was just hot as hell.

any who its on the list, I in no way think the oil is under 170! I'd fell the return but that's hot oil passing through a turbo... That's why I am even driving it, and the reason for posting, the water could be 100 degrees so long as my oil is warm enough to do its job.. I was reading too cool of an engine is a bad thing(increased wear,poor mileage...), but does a ka fall into that category, I know the cts will play a big roll in performance, but other than that I don't see an issue. Maybe I'll turn off my pusher fan and see if that brings it into the 160*. Main use of the car is beating it like I stole it, so the increased cooling is nice(no more 1.45 minute runs ) I tried to put heat in it last night with a few hard pulls in 3rd and 4th and the thing never moved. Outside temps probably 85+. The car when I first went de would stay around 170 then go up to 190~200 on the highway(t25 setup always boosting)..

IDK just dont wanna hurt anything else for a bit...anyone else?

[DevilMB3017]

I know I make the most power on the dyno at just below boiling... Around 99*C, or like 210*F. My cruising temps (T3/4, no boost, ) are usually around 80-85*C, or like 170-180*F...

I'd check the FSM to see what the normal operating temps of a KA are and keep it in that range.

[neverlift]

yeah I need to look in the fsm, just curious as to what you guys run personally..

I know my camaro ran hotter than I would ever want a motor to run, 180 was cool lol. I know it feels a bit down on power at this temp, 170 it has good power, and yeah even at 200 power is good. But I want to be able to get 5 minute runs, I need to go check how it does while sliding but hard straight pull dont even get the temps going.

Does the sr rad cool better with the inlet/outlet setup on opposite sides?

[480sx]

Between 185-210 is the ideal coolant temp range. Colder, your engine runs less efficiently. Hotter, its.. just bad.

[neverlift]

well it got over 150 today, hit 165 after 20 minutes in the drivethru.. then almost immediately dropped back to 150. Looks like I need a thermostat, or run my fans off a temp switch I like my min to be around 165 and my max around 185~190. maybe take off the mechanical fan...idkdidnt see anything in the fsm.

[DevilMB3017]

I don't remember your setup off the top of my head neverlift, but just a little info for you...

In addition to the stuff in my sig, my electric fans are controlled by a temp sensor, and I use a Nismo lower temp thermostat and the Koyo rad.

My temps on the dyno never really have gone over 212*F, but stay above 165 even at idle. This includes 1-2 minutes at redline in autocross and 5-minute or so drift runs and I don't know what I'm doing there :P

[neverlift]

I suck at that and assume everyone knows all my stuff

its a de swap into a sohc chassis has an sr 2 row godspeed rad, a gutted thermostat, stock mechanical fan, a 12" zirgo as a puller and a 10"zirgo pusher(this one is mainly for the turbo feed cooler)

both fans wired off 30amp relays.yeah I dont think I have hit 212 with the old rad, I notice the temp getting to 200 and I go ahead and start the heater and cool her down... 165 would be ideal IMHO enough to keep itself in check and allow me the heat needed to make power(feel the car is down some). It felt good right after I left the drivethru, then cooled off and felt a little slower. I know this wont fly come winter

you need to run a thermostat, its very important for warm up and keeping your engine temps where they are supposed to be. 170 to 210 is what you should be at. anything cooler then that and the ECU is running in open loop (warm up mode)

OPEN LOOP

Definition: A mode of operation in a computerized engine management system that occurs after a cold start. During open loop, the computer provides a fixed air/fuel ratio that is richer than normal to improve cold driveability until the engine warms up.

[neverlift]

well I didnt need a stat(w/ old rad). It warms up fairly quick and it is coming out of open loop, I can tell the diff in how the motor sounds, just running a down pipe. Also note no uber rich conditions except under boost. Like would be expected if I was still in warm up...

Just add it to your sig, lol.

That's a LOT of cooling power man. Three fans? Ditch the stock clutch fan, first and foremost. You'll free up a few horses based on that and it'll run a little bit warmer. You might want to go get a $5 dollar universal t-stat too.

It's a good start at least... lol

[neverlift]

yeah I saw 160 balance high performance ones for 8 bux I think, might start there. Also I have water wetter in it its florida and these 105+ heat index days are not stopping lol.

I had a leak in the rad and assumed it was something else, I have so much crap in front of my rad... I assumed it was airflow, I made an a** out of myself...

Yeah plan is to drop the clutch fan, but man are they reliable! And I have not seen much gain with a ka when taking the fan off? I did on my ss s10 though!

[480sx]

You need an OEM T-stat. Worth every penny, and you have to run a thermostat dude, especially for a daily driven car. None of that lower temp nismo trash, OEM t-stat or.. some other crap.

The fact you have a gutted t-stat is the primary reason your cars not getting hot and has a problem. Wayyy to much flow in your system and to little pressure.

You also have a metric ton of air flow through your rad lmao, i hope thats controlled well. You dont want to overcool your radiator/coolant.

[neverlift]

so stock stat or dont bother? so a nissan stat. I've had no stat for years, but on a crappy radiator that has been leaking for god knows how long. Never had a problem. Without a stat I could see I was moving the water too fast to do anything, which is why I put a gutted stat in, in return it slowed the water down ALOT. The stat is now basically a restricted area so it has to build pressure, no?

yeah I know I have alot of air flowing, but I have an IC,turbo feed line has an oil cooler,condenser,and the radiator to move it through, and plans for a ps cooler and an engine oil cooler to go in front as well. The EOC is gonna damn near cover my condenser, and the ps cooler isnt very small. I want the car to be able to go slap off for an hour! I am sick of cooling down things.

not trying to be difficult guys I just have never had an overcooling issue. when it stops raining I'll pull a fan, gonna flip a coin and see which lol. I'll have to get a stat next week or sell some parts...

thanks guys keep it coming

[480sx]

Well, the gutted stat is going to help a lot over having no stat at all. Say, its like having instead of a full inch tube of flow, you have a restrictor in that flow that will only allow sayyy, 3/8ths of that inch to flow through at any given time. That will raise pressure over what you had, ect ect.

However, the engines coolant system is designed from the factory to work perfectly just as its setup. Cars need thermostats. End of story dude lol.

[neverlift]

no my car being totaled is the end of this story , I'd insert an icon but I cant find one of a guy blowing his lid clean off. with a rifle so its gonna be messy

[480sx]

We here can usually help you fix your problems, or take so long trying to help you fix them that you total your car in the interim. One way or another usually we can get rid of your Ka(T) problems.

KA-T FTW!

Sorry about your car bro, hope it wasnt your fault.

[neverlift]

def not my fault, I dont run reds, and I dont drive any kinda stupid with my son in the car, he is my world. Plus why would I do that risking all my hard work,money,time,blood. Kinda funny she got out all omg I'm so sorry, then a couple friends and mom and dad show up, all the sudden I ran a red The friends claim to have seen it all happen from a solid 500 feet away while carying on a conversation... tell the community officer they have never met the girl, go on in a later statement that they knew her a little, then in an even later statement finally admit they have known the mom and daughter for a while. Cop catches the ky thats on the way to my butt and writes it up as conflicting stories, take it to court. I know I ran no red, I know she ran out blindly(big truck in front of her was in a rush as well). I've had no infractions in the past 5~7 years man, I drive like I have a little sense. Since I've had a 240 I think I have not had any.

ANy advise is welcome, I think my bad back is worse, and no not one of those get rich things, like my fuct legs or more fuct, my arm after any lifting is getting a streaking pain from shoulder to pinky finger tip, I passed on the er and am going to my doc in the am.

[480sx]

Cant really give you legal advice online other than get a good freaken lawyer. You have a very winnable case, in a lot of situation the accident and the hard evidence speaks for itself. The fact they lied to the police and basically admitted to it should be enough for your insurance company's lawyers to tear her a new a-hole.

Im glad no one was seriously hurt, especially your son holy s*** dude. I would be going ape s*** if some bish totaled my 240 WITH MY KID IN IT, then started telling lies about it to save face.

First things first, do what you can for yourself. Cold compresses, up to 6 times a day for 20-30 min at a time to any areas that have been damaged by the accident. DO IT NOW. HURT LESS LATER. Go Easy on yourself and your body for the next few weeks. Go see a doctor if you possibly can asap, your entitled(under our legal system) to compensation for it all. In addition, the doctor can provide you with information and proof that you might need in court to get compensation for your injuries. You also only have one body, what is money?

With the way this bish treated you, you should take her for what she's worth IMO. F that, shes nasty, get a nasty lawyer.

Sorry man, GWS and GL.

The other part of helping your body heal is fighting the pain(injured area). Say it hurts really bad to move your arm up to where its on the same plane as your shoulder. Well, move your arm up until its nearly there with a manageable amount of pain, and then let it go back to resting for a bit. Push yourself basically, your body will tell you if your pushing to hard(it will hurt bad lol). After you stop the swelling associated with injury, you have to try to keep the mobility and flexibility of the damaged areas by keeping them 'active' and limber. Being a p**** about it or being a hard core idiot is only gona make it a lot worse in the long run, maybe for the rest of your life. There is a small window of time that your body can heal extremely well from an injury or ailment, and you have to make use of that time as wisely as you can. If YGAF.

O ya and.. Drink water lol. If your pis is yellow, your not drinking enough water. Dairy and 'calcium products' as well help rebuild damaged bone, ligaments and joints. Protein will rebuild muscle and will also speed healing, but muscle usually takes care of itself and is not a primary concern.

thanks man, I am going to my personal doc in the am! I know its spinal as I have a bad back that limits me already, every time I wrench I hurt for a day or three, not oh my muscles hurt but someone is trying to pull my spine out my ***hole kinda pain, it is intensified, a lot. Ice isnt going to help this s***, its nerves being pinched and probably the jelly inside my donuts being pushed out The girl didnt lie her stupid s*** head parents told her to. But she let it go down, the cop was writing it up as my fault but realized the witnesses and the girl knew each other by the actions. It took all I had in me as a father to not slap the girl, then her dad and some prick in a nice suit. But I must strive to be better for my son, if I go nuts and beat some b**** to death will he not think its ok to do so. Trust me brother as I write this out I beat back the rage with some fierce love. And not for my son I would have got out with my 3' breaker......

[480sx]

Uhg the back is a bad thing to f*** up. Modern medicine has yet to be able to do d!ck s*** thats significant(IMO) for the back.

Cold will still keep the swelling of your disks and all that crap down until it subsides and healing begins. Swelling is what causes the majority of the pain after an accident, or most any injury beyond a flesh wound.

[neverlift]

should have seen my options back in 01, it was let them install a shackle like thing that screwed into my spine and basically take any movement from those 2~4 vertebrae , or let them go in and scrape away the "jelly" that was pushed otu of the ruptured disc. And he left me with a disc thats herniated like its no biggy.

actually they have come a long way, so far as a full titanium disc, it has full movement, but unfortunately I am not rich.. and the minor back surgery I had cost well over 50k

[neverlift]

btw guys the mechanical fan was removed 2 minutes before this trip and teh car was running at 165*

[WDRacing]

Damn dude...

Lawyer up and get everything documented where health is concerned. I'm glad your son is ok, I'd have freaked if my son was injured.

[480sx]

I wish i could share some rage with you, although i hope your not in short supply.

[neverlift]

listen hear you damn ol mad hippy I need some anti rage meds. I cry every ten thinking my son could have been hurt. He is ok, I think I am alright, I feel sore and back to semi normal pain level.

Yeah if I start feeling anything I am gone to the doc. Its looking like her insurance is against her already. I talked with state farm and the guy sounded blasted about her witnesses lying and her going from sorry sorry to he ran a red... looks cut and dried, her ins will be here monday to get pics access the damages... hopefully be ready to cut a check next week. or it goes to court, I am willing to take a lie detector and stand by it, her,her witnesses and her family probably dont feel that way. luckily I have a local forum full of support and these guys are beating the street trying to find me something I can afford, if her ins pays I will be alright but if I have to its gonna be a ground up build, from a shell

[480sx]

Did your crank pulley get hit?

Honestly dude, i would be pushing this hard. Get a lawyer, go to the doctor, now. You deserve money for this BS, it is definitely worth a civil suit, you have them DEAD TO RIGHTS. It would be one thing if the bish was honest and just made a mistake, but what she tried to do is unacceptable. Dont let this pass by, dont be mr nice guy on this. Her own idiocy could have cost your son his life, or you yours. That is a HARD passenger front side hit. In addition, her, and her family try to destroy your life by lying to the cops, after they have already destroyed your car. Dude, take that b**** for every penny a good lawyer thinks your entitled to. You might lose money in the short term, but in the long term trust me, it will work out for the best unless your back is screwed up because of her.
