LOL mixing oil with the fuel.......

The same could be said mixing coolant with oil ;)

If its not already nominated, i'm adding you to the list for Car of the Year.

 

Its such an unsuspecting car from the outside too. Its not till you peer through the tint and see the cage or notice the brakes etc that you start to suspect what its really capable of.

 

I laughed so hard when I you were lumped into the super sedans at round 1. :lolcry: Purpose built drag cars...... and what's that corolla doing lining up!? :hmm: :lolcry:

 

Oh and I used to add some castrol caster in with fuel when I was still running an OMP. Smells so nice....... "Are you running that on Methanol?" :lolcry: Which is a fair question as its only the addition of castor oil to ethanol that makes methanol smell the way it does.

Thanks for clarifying that up. Sounds like we use the same oil. Time to go top up the oil I think.

 

Do you remember some bloke chatting to you in the bottle shop drive through in G'Town about 18 months ago? That was me anyway. I was there for Dans wedding. I think i meantioned my car as we were chatting about your beast. You have the best sounding/angriest rotor ever buddy.

Ha ha thanks mate. yeah i remember you. Never ended up taking you for that spin did i. next time your down give me a buzz and i'll get i'll take you for a lap, think Dan might have my number.

Interesting, very interesting :fuzz:

I used to run some caster oil towards the end when i had the 5K. Not for any benefit, other than i had some laying around from my nitro rc car days. Used to smell shit hot, and turn a few heads when they caught a wiff.

 

I pulled up behind a harley today at a red light. He turned around to see what was making all the noise :P

I also put 200ml of oil into the tank this morning. No real visible smoke from what i've seen, so i guess i'll stick with that.

 

I also dropped into Sandown to watch some cars from the fence. Jeebus has the security got out of control. The usual spots had all been fenced off and security was everywhere stopping people from standing at the fences and watching rather than paying. Pfft, i understand them wanting to make a buck.....but there are people that just want to see certain races or a few laps here and there in between their daily lives.

The security asked if he could search my car for grog or a bbq when I went to park my car. WTF? idiot, i'm just parking and watching the support races from the fence. As if i want to drive in and sit there all day and watch suped up taxis.

 

EDIT* Had a belly full when i last typed that, so i forgot to write what i intended to. 21deg day today, and whilst in traffic and back streets the water temps rose up to 100C. If i got up to speed and chucked it in neutral and rolled, the temps would drop back down to 90deg and under if i rolled long enough. So its only when stationery and when i give it the berries, that it was getting hot. Kinda weird considering its never done it before, even when i gave it hell. Its a new engine, new rad, new thermostat, new SPAL 16" fan and water pump was fine as the engine builder inspected and gave it the ok.

I have noticed that the hot exhaust etc in the engine bay radiates through everything. Its like the bay heats up, but the hot air has no where to escape.

As a result the oil temps soar to 5-10deg over water temps when stationary. I've considered sourcing a small fan for the oil cooler aswell, that will kick in when the thermo fan turns on. Thoughts?

Bled all the air out of the cooling system?

[Des]

Heat wrap on the exhaust ?

 

My Corona with the V6 use to do the same thing but not as bad, I lifted the rear of the bonnet about 10mm and removed the rubber seal. It made a huge difference in temps when stationary and low speeds but looked odd to me.

[kangaroosa]

Never bled the system - Never done it to any of my cars. I've run the car with the rad cap off and squeezed the hoses to force air out.

I've heard good and bad about heat wrap. Like early failure/cracking of the exhaust. I guess its something to look into as something has to be done. I'm not big on the spacing up the bonnet idea for air flow. It looks lame and dodgy.

 

Maybe i'll bypass the heater again and see if that cures anything.

[Raven]

This might be the JD's talking, but I suggest parking on a hill and bleeding the air out, or for dodgy specs, cut down a 2L coke bottle so you have the pourer as a funnel, wrap a heap of electrical tape aroound it so seals in the top of the radiator and overfill it, so its the highest point in the car.

 

Let me know how it goes :)

 

Air pockets tend to create hot spots in your cooling system, which wont be good for your rotary dude.

[kangaroosa]

I made sure the radiator was the highest part of the cooling system. I'll give it a go, because it can't hurt.

 

I'm thinking its just an airflow thing. If the car is not moving, theres no airflow to disperse the hot air in the bay. It just tends to radiate through everything.

At speed it cools fine. The SPAL fan pulls more air than my twin 10" fans ever did, so i'm tipping thats not the issue.

[kangaroosa]

Well theres your problem :P

 

See it kinda was an airflow problem......a lack of fan....

It must have had an intermittant connection because the fan was running when I checked it the day before last.

 

Now to get in touch with PWR to see if the warranty covers the switch. Not bloody happy about <5hr old part failing.

Any clues what would casue such an issue? Power Surge? That power feed comes from the relay which runs a 30amp fuse, so maybe the fuse is too high and the wiring failed first.

[Des]

Shit connection at the switch causing too much heat ?

[SLO-030]

That power feed comes from the relay which runs a 30amp fuse, so maybe the fuse is too high and the wiring failed first.

 

How Do you have it wired up?

 

From that it sounds like...Battery>> Relay>> Switch>> Fan.

[kangaroosa]

The +Batt feed for the Relay has a fuse within the first 100mm of the battery. I think thats a standard 15amp glass fuse. From there I have it wired the usual relay method. 4 Pin Relay (Earth, +Batt, Ign, Power Out)

Power out of the Relay goes into the switch and loops through into the + side of the fan. When the switch completes the circuit at the right temp, the fan gets power.

So I have a 15amp fuse near the battery and a 30 amp fuse in the relay.

 

The connections on the switch were spade terminals for ease of removal when i swap engines. They were firm and taped in place with electrical tape.

Atleast I have the option of upgrading the heat rating for the switch as i thought it was a bit low at 85C on 80C off. The thermostat opens at 83C.
