Prototype in Process: NSN Motorsports Manual Transmission Cooler

[CWiLL]

yea im def. wanting to do a tranny cooler kit too, im also tring to make a ton of power. just got to get the car on the road again and start from there. i will be calling you about this. thanks for the support in the Mazda community

 

[TurfBurn]

I'm hoping to get some prelim results tonight... I have to do some wiring modifications for some other stuff and a tweak to my wastegate actuator then I should be good to focus on the cooler results.

 

[TurfBurn]

Alrighty... went and did my test results... here they are:

Prototype Testing Results:
Car warmed and driven for 25 minutes prior to start of test w/ cooling system off.
12 mile stretch of road used for test runs, repeated boosting and acceleration/deceleration. 9 runs per pass:

Temp prior to testing start - 117.8F
Test Run 1 w/ cooling system on: Peak Temp - 120.6F
Test Run 2 w/cooling system off: Peak Temp - 134.4F
Cool down driving w/cooling system on following run 2: 118.6 after 7 minutes (120.9 after 1 minute)


Basically what I did was get the car warmed up and all engine temps up to full peaks by running around for 25 minutes beforehand. Then I went to a stretch of road that was hilly and straightish an made a pass down it with the cooling system on. I did ~9 2-5 gear runs (roughly 35-115 mph) seperated by roughly a half minute each. Then after that the last 3 miles I'd run just at an ever 50 mph and read let the thermocouple reader see if it would record a higher peak than during the run or not... (it typically didn't by any more than .4 degrees). Then I repeated the same run with the cooling system shut off... then during the last 3 miles I turned the system back on to circulate the hot fluid and get a temp reading... that is how the results above were gotten. The thermocouple was in the fluid return line that sends the cooled fluid back to the transmission..

So overall, I'm reasonably pleased with the results. I'm going to look at going to a slightly bigger cooler, but I think at the least these results are satsifactory... showing at least a 15 degree drop in temps in my short tests... I think the most important thing though is that with the system on I only got about a 2-3 degree temperature rise compared to 16 degree rise without the system on. Again I also measured after the cooler which isn't a "true" reading for the hot test... it could be a good number of degrees higher than what I got. But I wanted to be consistent and if anything deterimental to the system for "making it look good" so that you guys would have confidence in it's function.

Let me know what feedback you have regarding this!

Thanks,

Steve

 

[Mallard]

Sounds like a reasonable test and should be repeatable. I'm running Mid-Ohio in less then a month and will be looking forward to your release of this.

 

[TurfBurn]

I have a finalized bill of material parts requests in to suppliers for final quoting... I'll be offering 3 levels of the kit, basic, standard, and deluxe. They will vary the size of the cooler and what fittings are used (basic uses more barbed fittings instead of hose ends... etc.. ). The basic kit will use the cooler that was used for the prototype. Each step up will bump the core height of the cooler by ~2" with a final core height nearly 8"

I'm hoping to have final pricing and be ready for orders with a lead time etc setup for you guy before the end of the week... so that in theory you could have this kit by the end of next week.

Thanks!

Steve

 

[PaulMP3]

awesome.. i'm interested.

 

[CWiLL]

thats awsome. let us kno when ur ready for orders

 

[jrodhotrod]

Awesome Steve.

Looking forward to pictures of the different kits and all the details.

 

[TurfBurn]

I'll talk to my suppliers again today, and at the least I'll post the different level kit contents for you guys (I have those done)... Lead times is one of the major things I'm trying to nail down... I want to be able to tell you as exact as possible how long it'll take... (should be sub 1 week typically... but I need to confirm that... )

 

[tekkie]

yeah I am interested in seeing how big the biggest one is and how effective it is

 

[TurfBurn]

yeah I am interested in seeing how big the biggest one is and how effective it is

well, the basic kit... which is the cooler you saw on the prototype, has a core measurement size of 2.5x11x1.5 with 12 passes and a 7,500 BTU rating

The "standard" kit will have a cooler core size of 3.75x11x1.5 with 24 passes with a 15,000 BTU rating

The "deluxe" kit will have a cooler core size of 6x11x1.5 with 36 passes with a 20,500 BTU Rating

There may also be an option to fit a cooler with a size of 9x11x1.5 with 48 passes and a 29,500 rating. but the overall height is 11 inches and thus may not fit in the space with people having front mount intercoolers that come up behind the bumper like mine.

As you can see from the BTU ratings... considering how much heat rejection we yielded on the little cooler... the bigger ones will be MORE than capable of meeting the needs of the application.

sweet so get me one already (deadhorse lol

[TurfBurn]

LOL.. yeah.. suppliers are never as fast as we'd like them to be! I'll get those materials lists up sometime today.. and I'll harp on them to cough up my final pricing too... I try not to hound them too much so I don't piss them off (our volumes aren't quite high enough to make them want to cater to me at every pass) but I'm after about every other day if not more often.

I'll try to have some news by the end of today regardless though!

Steve

 

[TurfBurn]

Alrighty.. I did talk to the supplier yesterday... they have had a couple people out with bad flu bugs or something... so they are totally swamped and behind. I got the rough estimates though on a few of the parts... so hopefully yet today or tonight I'll get that pricing finalized and posted for you.

Thanks!

Steve

 

[TurfBurn]

Well I think we can do this kit without brackets... but watershields will probably be necessary... given that... here are the bills of material:

Give it another go with the next biggest (standard) cooler and let us know the results! Be sure to test the basic cooler right before hand (since conditions from your initial test day may have changed).

Agreed, I would be very interested to see how the "standard" cooler performs compared to the "basic" cooler vs. no cooler.

 

[TurfBurn]

Well that is an extremely difficult set of tests to run because of how things are set up... and getting the results is also very difficult due to how the test has to be conducted... I'll do my best to get something comparative... but given identical ambients, the rest won't matter... so they don't have to be back to back.. additionally, simple themo calculations will yield that there is a significant difference just simply due to the fact that the cooler has nearly twice the heat rejection rates... I will do what I can though...

 

[Brian MP5T]

I Agree with Turf, Testing is not required for all setups. It works, we knew that it would because you are taking Hot Oil and Cooling it, Obviously it will have a cooling effect. The Tranny Bell has bad heat disapation. I believe that even the Basic will be able to your tranny from whatever you throw at it. I agree that the temp is more than likely the cause of the failed trannys. Tranny Oil is not like coolant. An engine will make shitloads more heat than a MTX so i believe that the cooler even with it's basic heat exchanger will more than cut it for all HP and Driving styles.

Great Job and initative on your part!

 

[TurfBurn]

Thanks Brian!

I will do what I can though to try and get some numbers for you guys though on the Standard kit... but getting back to back is very hard because of the lines getting hot and so forth and trying to get in to switch the cooler.. I will try to run the same route, and the same ambient though for you guys and that way I can control it as much as possible..
