Any other cooling mod ideas? Getting a Dual Fan H/E

[DaFreak]

Freak--- Either your tune isn't as aggressive as beasts's or your IAT2 are causing the pcm to pull timing. At the same RPM beatst is at 22 degrees where you are only at 16 degrees.
Check to make sure your fluid is circulating freely. No kinked line and the pump is primed and working correctly.

Thanks for the tip, I'll check it. I also plan on doing some more logging to see if the reading was a fluke.

So Freak, what is your current psi, what mods, and what blower are you using?

UPDATE:

I was snooping, and I know some of his mods.

He does have an OD lower, but doesn't tell me 100% that he has a stock Eaton, if it's ported or not, etc....

Yep, 10% OD lower, 2.65 upper, VMP Dual 72mm TB & Big D Elbow, and a self ported stock SC inlet to match the elbow. Tune was supplied by VMP as well.

Also running Van's radiator and cooler plugs (I can't remember which ones).

Currently I'm running a 50/50 coolant mix too although I could get away with 70/30 as it doesn't get too cold here.

I had planned on doing another log run tonight but once again it's raining here. Looks like Friday is going to be nice so I'll post up then.

Maybe we should start a separate topic for this?

Let me know,

So, is it hotter at wide open throttle due to your blower spinning faster, or is it because of the 50/50 mix, or is it the HE?

Guess we won't know until you go to a straight water mixture with this Amsoil Coolant Boost. (1 bottle required)

Freak, buy some of the Amsoil additive, flush your intercooler system, fill with water and additive only, then retest.

I will have updated testing by tomorrow night if all goes well. We will see what my temps are now that I'm spinning the Eaton faster.

Ordering now from the Amsoil website. I'll likely take a week or so to get it done and do some logging.

Good deal,

That will give me some time to finish up the exhaust on my car before re-testing.

Hey Tob,

It would be nice to see the results of a Whipple setup.

 

[UnleashedBeast]

I had everything ready on my car tonight, so I decided to go out for some testing.

weather.com said the ambient temperature tonight is 73*F in my area

First WOT run (115 mph) - IAT1 versus IAT2 difference was 39*F

Second WOT run (133 mph) - IAT1 versus IAT2 difference was 47*F

Third WOT run (133 mph) - IAT1 versus IAT2 difference was 47*F

The overall average of IAT1 versus IAT2 difference was 27*F

All of these runs are with every mod in my signature, and I am spinning a ported Eaton to the edge of madness. I don't yet have a boost gauge in the car, but the factory boost gauge slams 15 when I go WOT.

*Recall that Freak logged a 73*F difference between IAT1 and IAT2 at only 108 mph*

So, now that Freak and I have comparable setups, what would you suspect is causing the Revan HE to outperform the AFCO? Is it my straight water fill or is it simply a better core? There is another possibility, as my blower was race ported by Brian (Posi), and Freak's is a self port match to the elbow only. This is probably some of the heat difference.

Well, I looked back through the entire log again last night. One thing stands out. The max speed WOT values we were looking at came at the very end of a nearly 30 minute run and I had just done 2 smaller (less speed) WOT's right before that (literally 3 in a row). I saw the IAT2 climbing back on the first WOT and by the time I hit this one the IAT2 was already nearly 130! So I think I killed myself here. How does your max speed WOT fit into the sequence of the entire run? I think we might need to synch up when/how we perform the WOT's

Another thing I just noticed is that your coolant temps are super low compared to mine and I'm thinking the Amsoil booster should help a bunch with that.

I did the 115 mph run at the middle of the data log, one 133 mph run towards the end, and the last 133 mph run at the end of the log. It doesn't matter when I go WOT, as the temps will come up at high RPM, but fall drastically when I'm back down to low throttle positions or cruising speeds. The Revan HE really gets the job done, and I'm extremely pleased with its performance. I have yet to see an IAT2 temp above 130*F at 80*F ambient or less. The Revan HE seems to not allow for a IAT1/IAT2 difference greater than 50*F, and 48*F difference is the largest difference logged yet. I'm sure I will exceed 130*F IAT2 when Florida's temperature rises above 90*F.

The average temperatures will display the normal differences in IAT1 versus IAT2 when at part throttle and cruising speeds.

That's the 170* Reische thermostat, not so much the straight water/ADCB mixture. I noticed that even with cooler ECTs, my IAT1 versus IAT2 difference were not affected at all with my previous setup. It may be helping the over driven ported Eaton, but I wouldn't really know unless I put the factory thermostat back in the car and re-tested.

Maybe you can do another log where you hammer it 3 times in a row with approximately 10 sec between the 2nd and 3rd making sure the 3rd has the max speed?

Tomorrow's gonna be a good day here so I plan on posting up another round of logs so we can do some more compares.

I've done that already in 78*F weather, but didn't save the log. I still couldn't get the IAT2 temps to rise above 130*F

Dafreak,
Do you have a ported supercharger or just the elbow ported to match the inlet?

 

[Wingrider]

Is there a set recipe for how long to drive, where, what time spent before/after/during driving at certain RPMs to even out this logging? It sounds hard to standardize.

What are you going to log with anyway? You still don't have a tuner!!! oke:

 

[UnleashedBeast]

I've been collaborating with a friend and I've been given a valid point.

The 2010+ cars have an added snorkel on the front that constantly feeds fresh cooler air into the air box. The 07-09 cars don't have this, and it's a disadvantage. My car is a 2009, DaFreak's is a 2010. He has the advantage of the snorkel, but my car is plagued with hot engine compartment air entering the intake.

This is more food for thought when looking at the test results. I'd honestly like to install something on my car to assist with cooler air for the intake, and then re-test again.

I ported the SC inlet to match the elbow. That was the only porting I did on the SC though.

More Data Logging

Was a great day here today so I got busy and did some more logging. For some reason some of the values in the Max column couldn't be found in the individual time slices. But I got very close. I included two sets of data/pics. The first set are the values at max speed and the second set is at max RPM's. I added a couple of data elements since the last time too (just for fun). The pics include a chart where I plotted speed and IAT2. The chart range focuses on where the IAT2's climbed the highest (not the entire run).

I see a much different story this time. IAT2's never get above 123 deg. Oh BTW, it was 65 deg out today.

Thoughts?

My run (115 mph) - IAT1 versus IAT2 difference was 39*F

Your run (100 mph) - IAT1 versus IAT2 difference was 54*F

Your run (118 mph) - IAT1 versus IAT2 difference was 53*F

Looks like my setup is still maintaining an average of 14.5*F cooler. What I want to know is....

1. Is it the ported blower and port matched VMP Elbow

2. Is it the water/Coolant boost mix

3. Is it a superior core of the Revan Racing HE versus the AFCO.

4. All of the above combined

Me too Beast. Next step for me is to add the Coolant boost and re-log. I should be able to post up early next week.

How much to have the blower ported by POSI? That could be a future next step for me too.

Brian charges 500.00 if you ship him the complete blower, but only 450.00 if you only ship him the case. I took mine apart (very easy) and saved a lot of money in shipping and the port work.

You also pay return shipping.

Use tap water from your water hose to flush out the intercooler core and heat exchanger. When all the anti-freeze is gone, re-assemble the system, burp the system, and add Coolant Boost (1 bottle). I think once you get all the anti-freeze out of the system, you should notice a difference in your datalogs.

Porting a blower usually lowers downstream IAT's about 20*-25* this was the case at least in the Ford lightning trucks. I think the GT500 blowers are better from the factory but will still see a benefit of reduced IAT's. Also as you know antifreeze isn't the best at releasing heat, pure water would be much better. I would do one mod first either reducing the amount of antifreeze, then re-data log. Then the another mod and re-data log to see if you can isolate how much each mod nets you in reduced downstream IAT's.

I agree that a decrease would be seen with a ported GT500 blower, but not as much as the M112 blower, so I agree with you there. I expect it to be a combination of porting and coolant mix.
