944 Electric Water Pump
#31
I see this working out even better with megasquirt. Ditching the controller and making megasquirt keep control over the pump... My questions. How can this be rigged better. Can it be rigged to be behind the power steeting cooler? So that it can be run in stock line of flow to maintain the use of a thermostat . Other than that, removing the impeller and pulley, roller on the tensioner and the accord belt.
Or if reversing flow proves beneficial, also flipping the thermostat around and move the pump on the parallel side described? I dunno, im in theory land here. Would this be more beneficial with the linsey racing steam vent kit should any bubbles exist in the head?

The Chevy LT1 made use of this in the early 90s to make ~340HP on a then 40-year old engine and still pass smog...

Also I decided to flow the coolant in reverse to make the head cooler as stated above. One thing I should mention is I do not drive my car hard until the pump is running on constant. because it is in intervals of on and off until operating temp is reached. I am sure the LR steam vent would work great with this as well, (I plan in the future when I do head work to put that on) just to make bleeding the coolant system that much easier.

Sounds like a must do for anyone planning high compression or high boost. While doing this, i would feel more comfortable doing high compression with nitrous with this. I still wonder why no one has developed a block guard for this motor. That to would help with higher revs reliability asuming someone wanted to run significant boost also at a higher rpms.

I can see it being big money to make these engines rev up high. Not only would you want to change the internals but the transmission is not geared for a high rpm monster. When I get down the road to building my engine the highest I would want it to rev would be 7500. And even then that might be a little too high for street use with not enough low end. I am sure you could make a block guard like the honda b series engine does. However this engine doesn't have vtec or even 16 valves.... my engine is a 8v 2.5L so it has weight on the crank unlike a 1.8L. Not saying it can't be done, it would just cost some money to make it last.
Edit: Did a little google search and it looks like the engine came with a stock crank girdle? Or at least the 88 engine did. can anyone correct me?

Don't worry, I'm in perspective here. I am aware of our engines. Again i was just thinking that a turbo guy could run a bit more boost with this reverse flow and.if having open deck blocks would become an issue.

Am reading this for the first time today. Also can't see pics on my work laptop but looking forward to checking them out tonight. Sounds like you really did your homework on this.
My car is a 500-600 miles a week daily driver. Let us know how life is going with the electric water pump every now and then. If it improves gas mileage any measurable amount I am very interested.
Thanks for all your trouble for properly documenting this.

Removed power steering, removed ac, underdrive on crank and alternator, Changed the ignition system to a nology coil and hotwires, halo spark plugs, removed 60 pounds of subwoofers from the hatch :P
I still need to change out my 17" wheels the rears weigh like 30+ pounds with the tires.
(OT) In your avatar is that your 944 with the different hatch? I have always been a little curious about those as for weight savings but wasn't sure about blind spots.

I can say that it maybe got me 1-2 mpg's however the way it pulls makes me smile everytime. I get an average of 28-30 mpg When I first got my car it was only doing 19-20. Other things I have done to it aside from the water pump are,

I have done away with the power steering system but can't say goodbye to AC.
I am no expert but since your wheels are 'unsprung' weight changing them might not be that much of a saving for you. But by all means keep me posted what you find out. It would have to be a pretty big saving for me to get rid of my 18" wheels, like the looks too much.
By 'the pull making you smile' do you mean it helps the torque of the car that much? That would be a plus for me as well.
Thanks for info, have a good Sunday.

Also with no exhaust, intake, head, or compression mods, my car has a good amount of torque and power. I also forgot I have a FRwilk chip as well in there. My test mule I run against is my friends honda civic with a b16 that we modified together that revs to 9k and puts out 193 to the ground. I can start to keep up with that thing finally but it starts to leave me around 40-50 mph. (Usually do rolling starts at 5-10 mph never dead starts) benefits of living on a private road

Reason why I want lighter wheels is because I see it as drive train weight. The lighter the rotational mass the easier it is for the car to accelerate and brake. It is like the concept of a light weight flywheel you can rev faster and engine break more efficient as well. Exception with the wheels is the brakes will work better because there is less rotating mass to slow down.

Honestly I have not been able to identify them. The fronts are 17x7.5 with 205/50/17 Continental tires and the rears are 17x9 with 245/45/17 Falken tires (just replaced the rears today) here are some pics of them if you want to identify them for me (Also get to show my car haha)

Edit: Well through some random internet searching (I have tried about a dozen times before) I found out what these wheels are. Sport Edition Wheels Cup 4. Also Pm sent
