ROFL!!
I think a stock water pump will do just fine. There shouldnt be THAT much more friction to justify a $500 electrical pump. Plus, the aluminum piping that Im using will cool the coolant quite a bit as well(if I provide airflow, or dont tin the bottom of the car).

good question. seems like it would be harder to push more fluid through more pipes, more friction right? an electric water pump might be the anwser.....OR a sohc with no internals that could push your girlfriend in a twin engine boat downhill, but if your running it might not work unless the boat is faster than a sohc with no pistons or a box on the floor that you just add the vector to and sutract the balance of your checking account.

Haha!
Actually I think the factory pump would be fine...it'll just move the fluid at the same rate, it'll just take longer to get to the rad, and longer to get back, but it will still be cooled with the same effect by the rad.

plus won't more coolant have more thermal mass anyway so even if it does move slower it can absorb more heat? i think. Thats the kind of thing you would just want to try out first, since it's easy to setup or change later. it's just some pipes ya know

yep, my thoughts exactly. Oh ya, Im stealing my GF's(Tcchikracer, Jen) 3" thick Griffen radiator. The things almost the size of an FMIC, but its a radiator
Yes, more coolant means it can absorb more overall heat, especially if its in motion.

Have you completely poo-pooed the idea of a radiator positioned somewhere other than the front of the car? If you're thinking of tinning a floor for the engine compartment, you could louvre it to bring air up through a downward-facing radiator. It works well for intercoolers on GN's running 2 bar, so I'm sure it would work for coolant

Just curious. Wouldn't want to suggest that you don't know 100% what you're doing because it's obvious you've at least entertained every step of this process. I'm stoked to see it get finished

Ive pretty much decided to keep the radiator in the front, just because of direct airflow. As for louvers, etc, Im not an engineer, and I doubt I could actually achieve direct airflow into a radiator anywhere OTHER than the front of the car....withOUT creating lift.
Not that it doesn't seem you've already decided on what to do, but directing air UP towards a downward facing radiator would create downforce, not life
It'd be like a wing on the underside of your car... The only hitch is that the air has to have a way to LEAVE the engine compartment (trunk), also. I'd go with the front mounted one just like you were saying, anyways, though.
Good luck!

Explain to me how directing air upwards towards the bottom of the car creates downforce? Last I checked that was lift.
Anyway, great idea Tinker, I hope to see some sick vids when its done.

Okay i'm four years old and stupid, here's how. Picture a spoiler. Got it? What's a spoiler do? Woah. Directs air UPWARDS and produces DOWNFORCE. Lets say it together:
"Directs air upwards, and produces downforce!"
Now, mount a spoiler under the car. That would: DIRECT AIR UPWARDS (through the downward facing radiator) and CREATE DOWNFORCE.
As I previously stated, that is assuming that the spoiler / air dam doesn't create a high pressure area in the trunk, so it would have to be vented. You could even make double use of the effect by having another air dam outside. I'm not going to explain it any further, though, but if your STILL curious, go do just a bit more reasearch.
Oh yeah, and tinker, your the man, and I feel bad for all these people taking up worthless room in your posts.
Good luck!

If you pulling air from under the car and putting it on top, you're releasing the pressure under the car and increasing the pressure on top of it. Downforce.

</TD></TR></TABLE>
actually, the downforce is created by the difference in pressure between the top and bottom of the airfoil (spoiler). how is there a pressure difference? well, the camber design (curvature) of the airfoil forces the air on one side of the airfoil to travel faster than the air on the other side. this difference in velocity causes a difference in pressure (since these two are directly related). the side travelling faster has a lower pressure so the pressure on the flat side causes downforce. basic aerodynamics.

My old FSAE team flow tested a K&N vs a mesh screen, the K&N flowed better.

Are you sure, since I'm not on the team anymore?
Besides, who wouldn't want a 450lb MR car w/ a 600cc engine running off AEM EMS?
It is all about reliability and driving, last year over half the cars didn't even finish, but we did, 25th out of 170 something i think.

Wait...were you on the GT team?
Yeah I would do FSAE if I had more time...my car keeps me busy enough. That thing could have so much more power though...the air intake restriction is a bitch.

Good to see the project is progressing! It's one thing to talk about it, or daydream, or only plan, but it's another thing entirely to actually do it. Good job. It'll be much simpler and much faster to get done then my mid-engine Prelude Mini, that's for sure...
