I only get about 2 miles twice a day to tune (my daily commute). So I do a tweak, and play with it, watch the wideband, plan my next tweak, etc. Takes time, but I have plenty.

Wires are 8.5mm. They add no performance, just greater rigidity and toughness (thicker insulation). I remove and reinstall these often enough that 7mm belden wires might not hold up. They went (partially) on rrounds' car and BoneEvil, and a few spares laying around. SLE still runs Beldens also. 7mm.

Still not sure on this one. IC may or may not work well enough for what I need.

I'm after enough (or more) to be able to drop from the 2.3/2.2 pulleys I ran last year to the 2.0 on pump gas. Mid-grade would be killer.

If I can't determine enough of a performance increase, it won't stay on the car for long.

Never the less, Will you have shown how this is possible, and judging by the temp drop, wouldn't you consider this as a complete success?
Don't give up on it, I'll bet you're almost there!

Cheers,

I still have a bit of relocation work to get the pump lower than the top of the radiator. The real testing will start from there, and finish when I see higher ambient temps.

Finally made my way back to this thread.

How did the expanded metal turn out for the rad screen? The pic is a bit dark.
Where are you thinking of putting the pump next, its getting tight in there for placement options.

Expanded steel looks great (epoxy wheel coat and clear) and just drops in front of the front core. I need to put some spacers in there to hold it about an inch away so it can flex if it takes a hit.

I'll also put a piece of window screen in front of that attached with magnets in 4 corners to catch bugs and small stones/debris. I can just pull that out and wash it when necessary.

The pump will be moving down behind the front bumper/airdam on the driver'* side near the foglight (probably just forward of the FWI, but lower than the top of the radiator for the IC). That will happen this weekend. This is probably the biggest inefficiency I've got right now.

That is where I installed mine. Except it is on the passanger side. I think you will see the results you are looking for easily on this one. Can't wait to see more data. I need one of those temp probes for mine too.

Got things plumbed and moved again yesterday. Too beat to post it. Pump is now behind the front bumper down low. Call it lower and to the driver'* side from the driver'* foglight. That freed up more space for a future slush-box if I go that route for the summer. Should need it for afternoon test/tune, but not for morning competition.

Added a little green food coloring to make it easier to see flow/bubbles. Thought red would make brown with the little bit of green coolant. Still burping out a few air pockets, but it seems to be flowing better now.

Car is running MUCH better, but more testing will be needed. I need to lean out my AFR a bit. A short run last night was running 13:1 at idle.
