Mirage (Re)build thread - Jerry

1. Ok
2. TBD. You found it.

Sulley, we can't wait to read your build thread too ! It kinda helps keep the project moving I think.

[Sulley]

Well I threw the idea out there. I thought it might be pretty amazing to get a number of us together with our cars somewhere. I probably need a year to be where I want to on my car. We could do something central like Dallas but I don't want to highjack this thread....

I'm not a fan of electric water pumps although they are sometimes necessary. Their biggest problem is that they don't flow enough to generate as much back pressure in the cylinder heads as a mechanical pump does. This pressure raises the coolant boiling point in the heads and keeps steam pockets from forming and creating hot spots. A good electric water pump draws a lot of current!

Not sure if this addresses Neil's points, but I reverse-flow my LS, with the water going into the heads first. So perhaps the lower initial temperatures, plus the pressure drop from that water exiting the block, help prevent the issues stated with electric pumps. Thus far I've been very happy with my remote pump. Another feature I really like is that air in the coolant system is easily determined by a cavitation sound at the pump, that gets quieter as more air is removed from the system. Almost dead quiet when it's passing 100% water.

[Manta22]

The importance of coolant pressure in the heads is important when you are generating a lot of power for some period of time-- racing, climbing a steep grade, etc. Normal street driving is pretty moderate so an electric pump can work just fine. Expensive, though, compared to a belt- driven pump.

[Sulley]

Would an inline pump in combination with a mechanical pump be an option?

[Manta22]

It might work but why use both?

[Blueovalz]

I have the same sentiment as Neil. I also wonder what kind of flow restriction exists if one of the pumps isn't turning. If it becomes restrictive, then two pumps doubles the risk of a failure, but probably provides little needed additional flow to keep everything cool.

I put the engine in. 1 man operation, just go super slow and keep checking clearance.

[Jerry]

Easy does it...






Putting in the transaxle and halfshafts next ...
