Prototype in Process: NSN Motorsports Manual Transmission Cooler

[Brian MP5T]

Like I said, I don't think it's worth the hassle. The numbers will be "General" at best due to the dificult to control enviroment known as outside. I think, Dyno would be the only way to test it under control, and even then... The fact that it does lower the temperature is all that it required for anyone to buy it. In this senario, any cooling at all is better than stock.

Agreed, I think just duplicating your experiment with the bigger cooler and noting ambient temp and getting it as close as possible would be a good "guideline" for performance difference.

I'm getting the "Standard" cooler shipped up to me tomorrow, so I'll run tests.. I"m also doing a lapping day this weekend that I'll run it through and I now am mounting a transmission temp gauge as well (not as accurate as the thermocouple I was running before) so I can keep an eye on it during the race to get an idea... I may run one lap session without the pump, and then one with it so I can try to compare on those... but we'll see!

I will accept any early orders if you guys are ready and want to order up now. Lead time for parts to ship in is about 1.5 weeks... I should have it down to under a week in the future, but 1.5 is what I'll try to stick to for now!

Thanks,

Steve

Why are you going with a less accurate gauge?

 

[TurfBurn]

Why are you going with a less accurate gauge?

You misunderstand what I"m doing . I'm going to use the TC again this week to re-create the test that I did previously.. however on the track I'll simply rely on the trans temp gauge... I can't have a calibrated TC reader flopping around in the car while I race and I certainly won't have time to check it at all when racing... so occasional peaks on the straightaway at the trans temp gauge will be all I can really do.. and I'm really more interested in what kind of operating temps we actually see running the cooler during an incredibly hard series of racing (four 15 minute heats on the track at high speed).

 

[TurfBurn]

I have all of my lead times and parts lists squared up... There are only two parts that generate the lead time (the pump and the hose) so in some circumstances I can remedy that with other sources (that cost more). So all told it looks like our general lead time will be 6 business days to shipment.

The new cooler shipped to me yesterday, so I should have it today. I'll also test the new mounting idea tonight with this and get more data. So I should have everything squared away. Dana is first on the list for getting his stuff at this point as I already have a pump for him sitting on a shelf... then anyone else that is interested or paid etc will be taken care of immediately!

Thanks,

Steve

Been swamped as usual... but got the "standard" cooler in... was somewhat difficult on my car because my intercooler comes all the way up to the top of the bumper support.. and that causes this cooler to rest right on top of it.. which made mounting difficult... but here is a comparison of the two cooler sizes... I should get temp data tomorrow if not yet tonight.

Thanks,

Steve

oooh that looks sweet, its bigger than the stock MSP SMIC lol

 

[daedalus]

holy big oil cooler batman.

 

[TurfBurn]

Wait until you see my transmission temp gauge install.. it tis teh hotness

I think the question of whether or not the "standard" kit is worth it and if it will more than a little adequate should be answered right there LOL. 24 passes on that cooler versus 12 on the little one.. the "deluxe" kit one has 36 passes... so it's taller... but same width/thickness.

and the pic is not here why(braindead

 

[TurfBurn]

LOL... because I ran out of time and didn't have the camera in the garage. I have to finish wiring that gauge up (signal and everything is run... just no power for the light etc...) and I'll get some pics... Have to get the car prepped for the weekend race... cooler and all is in and functional and I'll get some numbers off of it tonight hopefully before I finish prepping.

later!

Alrighty.. re-ran the tests tonight with the bigger cooler... the ambient was about 10 degrees cooler...

After warming the car up and beating on it, I reached a peak temp measured after the cooler of 120.6.

With the cooler on beating on the car appropriately, the temps continued to fall and at the end of the test they were at 106.

I then shut the cooler off and when to town on it again... and when turning the cooler back on reached a peak temp of 118.3.

Cooling the car down again I got the temps to about 100 degrees and still coasting down... so moral of the story is the bigger cooler whomps on the little cooler pretty well, and is more than effective.

keep in mind that because of where I can get a thermocouple in all the temps are measured AFTER the cooler, which is in large part why these temps all read a bit lower (the 10 degree ambient will help... but figure a 75% efficient cooler and that would in most cases only equate to about 5-7 degrees better cooling given even coolers being compared). So the cooler definitely is very effective.

 

[daedalus]

And you were able to succesfully shove this under the car somewhere? Awsome.

 

[TurfBurn]

Right up front where the other one was... I'll have to make a small bracket so you guys don't have to trim your front grill like I did... It'll be a little bit of a problem if your intercooler comes all the way up behind the bumper... mine ends up about 1/2" shy of even with the top of the bumper, and thus creates interference with the cooler and it had to be mounted high (I actually used the nut that holds the bracket for the AC condensor... that is what holds my cooler right now)... so yeah.. fits great and definitely does some serious heat dissipation!

Later,

Steve

Sweet, sign me up for the larger (standard?) sized cooler.

Am I all paid up?

On the pump you are paid up... the cooler and fittings aren't. I'll hit you up with an invoice for the other stuff per our original agreement and it'll make it more clear.
