More cooling questions...
Turbo Mini Forums

Would it cause further issues if I tried to create a crossflow cooling system through my engine.

E.g. A front mounted rad that goes into the engine through the core plug near the engine steady, and out through the top hose?

Your thoughts

Thanks

getting abit hot around the track was it? must be all that extra weight from your vmax sticker!

It wasnt too bad, but it would have been if it was any longer.

My rad is just fornicated and I want to make a good solution to my cars down fall

is it still the normal side mount then?

Why not use a red between the head heater outlet and bottom hose? Works GREAT!

Nic,

have you got the heater hose going from the head back to the top hose?

That helps a lot would you believe!

no nic i dont think so ?
wouldnt the water then go into the block and, instead of out of the block into the head then into the theromstat housing ,
it would go into the block ,straight out the end of the block and into the top hose....therefore bypassing the head altogether ...
id try a mini heater matrix in the pipe to the turbo water feed mounted in the front somewhere ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

ive been trying to find a coolant flow diagram for this (im sure ive seen one on here somewhere)

the thing is that water is lazy and it will take the easiest route possible so unless you do it in a certain way based on the flow through the engine (which i cant find) you run the risk of cutting of flow to parts of the engine as robert say.

but then i was thinking if its under pressure would it not flow through through everywhere it can get too?

also! im just thinking now about the flow direction, would i be right in saying it flows:

Pump > Bottom hose > Rad > Top hose > Thermostat > Head > Block > Pump etc etc.

if thats the case then when the stat is closed and the engine is warming up you will effectively have a seperate system with no thermostat in it and so unless you let it idle for a period of time to warm up with the air passing through the second rad it would take a looooong time to get up to operating temperature.

i say a bike rad/extra heater matix plumed into the system via a hose, as has been mentioned above, and well positioned would be the way to go.

pump sucks out the bottom of the rad, blows up through the engine and into the head, then out the head at either end

ahhh i just got it backwards then.

I'm with vegard on this one,

also could be worth going to a (good) lecky pump if you havent already.

yes you can fit a radiator between the take off on the head and the bottom hose, this is infact a factory fit standard item also called a heater. if however you get too hot with this in the car, you can use the air conditioning via the rotary control located on the door.

This is what I do. lol!

In the 13's at last!.. Just

trust me, this helps LOWER the temps. its tried and tested and many many racers use it on the A series engine.

i've done it and it works, i know TD has done it as well and found it helps.

red rad :)

I'd say that a green rad will be optimal.

My turbo has taken the place of the heater, but it goes back into the top of the rad to help it keep cool

Im not a fan of bodging (in my eyes) in extra rads all over the place, id rather have one thing that does the job.
My current rad is leaking from around the cap and needs replacing, so im going to go for something that allows me to keep it cool for increase track day use

Ive an electric pump waiting to go on, I just need to work out a solution and was thinking about being different

ahhh so its not as an adition to you current rad its to replace your rad!

i take it you were just thinking of a solution to the inlet and outlet pipes on different sides?

if you could block off the mech waterpump and then use the leccy pump on the "new" bottom hose you should be alright.

although from my clear knowledge of the cooling system in a mini in the post above i would wait and see what others say! lol

i would go for a front mounted rad, to go with for intercooler, move your intercooler across to the left put an mpi high compasity rad there instead and bobs your uncal :)

Nic,

the radtec rad in mine seems to be doing the trick, although i've not given it much in the way of beans, it seems to almost have trouble staying warm enough, thats with a 74 deg stat with 3x 3mm holes in it, and the turbo in the heater circuit going back to the bottom hose. and next to no fan on the waterpump(1" cut off the blades so 2" les diameter) at idle in traffic the temp gradually creeps up but drops back down quick enough if the lecky fan is kicked in.

I'm going to up the stat to an 82

would be an easy swap on yours (not cheap though), they also do a bigger rad than mine now too.

The car will keep cool normally, in normal use its ok. However when i drive it had for long periods it creeps up and up, or when its ultra hot it gets marginal in traffic

However on the way to castle combe on sat I was having troubles keeping the car warm (55deg)!!!!! doh

Im hoping to banish my heavily drilled thermostat

something that would be interesting to compare is an alley head, as i reckon theres only so fast you can cool an iron one.

I agree, although an alloy head would be preferable

na naa nana naaa

Nic, you could fit the same rad as me and have your IC in front (if there is enough room behind). With your Meziere pump you won't have any problems keeping it cool!

My car cooled down about 5-7 degrees over a 1/4 mile from 80 degrees down to 73, and that wasn't exactly driving gently!

Mine usualy sits at 73-75 degrees where ever with an 80 degree thermostat, so it never really fully opens. It almost struggles to get up to temp. If you were to keep your IC in front of the rad it might just be enough to restrict the air flow to keep the engine warm on long journeys (motorways etc when your off boost) and not restrict it too much when on the track!
