Hi,

I'm interested in running reverse flow cooling on my b20 turbo vtec.
Does anyone here run with reverse flow cooling? Is it worth doing on a honda?


Thanks

Nath

Chevy did it on the Vette. I don't think anybody else does.
Think about what you need to do this ?

Is this a race only engine?

Hi,

Its going to be used on the street and for alot of racing. I'm not sure if cooling is going to be an issue but I like the thought of the decreased chances of det due to the head being cooled first.

Thanks

Nath

why bother is my question hondas usually dont have too many cooling problems and when they do its usually a problem with a small engine compartment with hot turbo components and a insufficient fan setup blow or pulling the wrong direction.

Well its going to be a stroked turbo b20 in a eg. Its basically a race spec engine and hoping for low 11's. I just thought cooling maybe an issue. Reverse cooling doesn't just give better cooling. It has alot of other benificial effects.

Thanks

OK, first off who is going to make you a reverse flow water pump?

I don't need one do I?

I thought I could just plumb it in so instead of flowing to the block first it flows to the head?
The only trouble I was having was the thermostats as you need 2.

If you can not just plumb it in backwards then I remember reading somewhere that the golden eagle pumps can be wired in reverse. Not sure if the flow rate is going to stay the same.

Thanks

Nath

Yes if your going with an electric water pump then you could flow it backwards. It just depends how you plumb the system.

You could out the pump anywhere.

Is this a race only engine ?

Yes this is basically a race spec engine. I will still use it on the road occasionally.

What about all the thermostats though, thats what I can't get my head around.

Thanks


Nath

Think about how the thermostat works. heat opens it. Do you think it cares about from which side the heat come from...once open it will still flow the same amount of water ...right

If it was a benefit someone on this site would have done it by now.

PM Tony 1 and see if he knows anything about it.

He knows more then just about any buddy.

Give him all the info about your plans so he can understand the question.

with the electric pump and a aluminum radi you should have no prob at all running cool i have a built turbo h22 ina civic with a aluminum civic rad.,meitzer electric pump,and a oem style completely sealed hood and with that big motor the turbo mani sits very close to the rad.i have had the car in bumper to bumper traffic in august (90 degree weather ) and it still didnt go over 205*.

p.s....if you run the electric pump drill holes around the thermo to releive psi when the pump is on and thermo is cold
