GT500 IC/HE Pump Comparison

[1320 Junkie]

I have been following this thread for a while and I was wondering if you tested the pressure cap and checked the lip of the reservoir for damage/proper seal. It could have be pre-existing issue that only became evident with the increased coolant flow.

With that said, it still appears that there is a foaming issue that needs to be addressed.

Foaming is from the fluid level being too low...keep the level on par with the feed side(full submersion) and its a none issue....however you choose to achieve that. My buddy Jim Larocca did these mods 5 years ago with his 07...he runs the Ford GT pump though. Flow is 20gpm with 1" hose...with 3/4" its 16gpm if your gonna change pumps...go biggest you can get and thats the Ford GT....if you can find one.

The ford GT pump I believe is similar to the 13/14 GT500 pump and rated for 7gpm

It probably cost 5 times as much as the 13/14 pump.

The cap, reservoir and seal are all OK.

I have performed a purge of the system following Van's instructions and took Justin's advice on the coolant and happy to report that there is no longer a foaming issue.

That said I have only driven the car on the street, I have not had the car back to the track since the issue, but will report back after it's back on the track later this month.

Peruse ebay....I found one for same price as a new 13/14 pump

If this is the right pump it's pretty darn cheap if you ask me. I'm going to be talking to Jimmy about doing mine. Never mind I see this is the stock pump for GT500's

Post up some pics, I would like to see it and compare.

Thx.

Looks like a similar design and shape to the Pierburg made one on the 13/14s.

I was just looking at that. Steve, what was the original application for DR3Z-14A411-C?

Off the top of my head:

D - decade code, in this case 2013
R3 - product line code, in this case Mustang
Z - Ford Service Division

14A11 - basic part number, in this case a harness
C - design revision number

Am I right? Because I can't find the '13/'14 IC pump in at Fordparts.com (I've been through every category) or harness. I'm just wondering if it is indeed the '13/'14 GT500 production IC harness.

This is all I can get to come up if I try to simply enter the part number instead of searching through the proper vehicle, engine, transmission, etc...

Sorry for the delay responding, you are decoding the number correctly. Pigtails can have multiple uses although when I search my parts catalog by that part number it ONLY comes up as a '13-'14 IC pump pigtail.

You'll find different part descriptions between the service manual, parts manual and on line catalogs so always take them with a grain of salt.

Thanks Steve. If it is indeed true that Justin at VMP is no longer carrying the necessary harness(es) for this pump upgrade for '07-'12 GT500's, then I suspect there are a few that will indeed be looking for the appropriate pigtails to piece together the missing pieces to this puzzle.

You guys know where to find me for whatever you need, I'm not going anywhere.

I just got a harness/kit from vmp about a week or so ago. It was a pain bleeding the sys. But wow does this pump move fluid. Car definitely makes power longer. I have to run some logs for lund yet. When I do I'll see what kind of difference i have from the last ones.

that will generate a LOT of interest Scotsman. Thanks

Good man.

Normally I'd at least have verified if what I've read had any merit (or at least have pm'd Justin). But I've seen it mentioned twice in the past few days by two different people.:shrug:

Looking forward to your results.

I'm ordering up parts discussed here to make my attempt at installing the newer pump in my '12. Appreciate all the part numbers and other advice.

If you cut the rubber off the old bracket and drill open the slot in it you can screw the vmp bracket/clamp right to it. Just give the bracket a quick spritz with black paint and you won't even see it.

Has anyone run two pumps in series. After reading what the zl1 guys and ctsv guys are doing it looks like this would be the better rt to take.

 

[rdanzy]

if you run two pumps in series you will increase the pressure but little increase in flow. If you run two pumps in parallel the flow will increase with maybe an increase in pressure.

That's the stock POS that failed on my car.

Well my last track day saw the bottle breach again, I tried recommendations in regard to water/coolant ratios and reduction of total coolant amount and both were not successful at keeping the preverbal lid on the bottle, after 4 or 5 laps, overheating and significant frothing of the coolant continue.

This new pump is a beast and the entry into the bottle on the return is so volatile that the coolant continues to get aerated and hot, eventually stops performing, then boils out around the Cap and makes a mess...:shrug:

After looking at the 2013 GT500 Fiche it is clear that the routing is very different on the newer cars, the Reservoir is also smaller in the 2013+ set up, but I don't think the fact that I have Van's oversize reservoir, has anything to do with my problem. It is just flowing too fast and probably not even remaining in the intercooler long enough during the circulation.

Moving forward, I was thinking a variable speed switch on the pump may work and it's flow could simply be turned down a bit, the other solution, suggested by Tob, is one of his bypass set ups, a more complicated solution that may require some fabricated parts.

All opinions, on a possible solution are welcome, as I have to get this sorted and going to start a fix this week.

Does the variable speed switch make sense?
