Tell me about this.

BEGI Miata Racer Coolant Re-Route

Wondering if this little gem is the reason why our Miata struggles to keep water temps above 140-150F on the highway.

This has been discussed in length, and the general consensus is that it is an apocalyptic failure of a design that offers only drawbacks with no improvement on the stock cooling system.

search n00b.

wait.

actually yeah that's right, search n00b.

Thooper.

So be as it may, doesn't sound like it's causing my over-cooling, though, correct.





Sorry, i am n00b. I'm used to looking at this:

This is exactly what it does. Makes the engine never warm up with negligible benefit to cooling.

Ah hah! I thank you, good sir.

Now to see how easily this thing can be reversed...

Never saw that. Damn, that's stupid.

Wouldnt a racer re-route just be a kia neck directly on the back of the head with a 1/4" hole drilled in the thermostat and no heater core at all?

I don't know.

I'm guessing this thing is never going to see reasonable temperatures until this modification is reversed, right?

lol, did you get an NA?

Also, that re-route has been discussed on this forum many times with the exact conclusion in this thread.

Get the standard re-route, it actually works.

Yup. You might as well not have a thermostat as long as that "reroute" is installed. Honestly I'm not sure why Begi even sells them anymore, even on a full-time track only car it's a bad idea.

You MIGHT have a shot with it installed if you put some cardboard in front of the rad, if you really need to drive it somewhere in an emergency.

Depends on location. I ran the Begi Racer reroute for a few years on my car because that is what they shipped with their kits. During the winter in VA driving on the interstate I would never get above 140-150F, during the summer and such I could get up to normal temps, if just took me a while. I will say when I was on the Dyno in July down in Georgia, the reroute worked excellently keeping the car cool then.

Or if you just kink the heater core line. My car gets up to temp just fine (while up on jack stands idling to burp the cooling system), even in below freezing temps with the oil cooler's coolant line going to the upper radiator hose. You just cant have the full flow of the heater core going there.

Hrm ok. Gives me something to think about.

So they are taking the heater core return line and putting it before the radiator instead of into the waterpump?

Race cars have heaters?

hornetball

iTrader: (4)

Yep. And it still preserves the thermostat on the front of the engine. So the more the thermostat opens (when it FINALLY gets hot), the more the engine gets starved of coolant. Solves nothing. But probably an engine rebuilder's best friend.

Wait I thought it was an add on to the normal re-route.

hornetball

iTrader: (4)

Oh. Maybe it is. All I saw was that T into the upper radiator hose (which implies keeping the front T-stat). Am I looking at it wrong?

Leafy

iTrader: (1)

The long re-route hose would still be the upper radiator hose.

I'm confused. What do i have? It tees into the upper radiator hose.
