Technical: Air Charge temps you've observed with your blower
 

I thought this would be a neat thread to post your not-so-scientific data or perhaps if you did datalogging some valid data on how efficent (or how terrible) your particular blower is with thermal transition to the intake air charge.

Magnum Powers

8# Lower, stock upper
14.8 LBS of boost
Ambient air temp: 66*
AFCO dual pass heat exchanger, 15%glycol/85%H2O/Waterwetter mix

Begin Run
------------
Cruise: 109* @ 70 MPH

Kick-down to WOT

Terminated at 151*, 139 MPH

Close throttle air charge peak: 184*

Duration: ~10 seconds
-----------


As you can see in this example, with an more efficent heat exchanger, coolant with better thermal transfer properties and increasing air flow through the H/E, my system is inadequate to deal with the amount of heat the Magnum Powers generated on the run. Timing is reduced at tempatures exceeding 150* in an attempt to save the engine from detonation.

With that posted, I would like to see some results from Whipples, KB 2.4 and 2.6, turbos and the few centrifical users would be nice.

My results are not nearly as detailed as yours are, but mine are just an average of a season of drag racing.

Whipple-stock-block-13lbs
mid 12 second truck

after 3-4 'hot laps', my iat2's would go over 150 and the truck would lose almost a tenth each round after that.

Added a larger ic tank and afco dual pass with fans--
I have been unable to get it to go over 120, even after 5 rounds of racing. This is using no ice, but running the fans and the ic pump between rounds.

This was by far the best mod I ever done (for bracket racing anyway).


I just had my truck on the dyno again, and my tuner (JJ@WMS) said my truck had the lowest iat2's than any L he has ever seen. They were around 90-110 I believe.

tonight, just reinstalled cleaned IC. filled with 2 gallons of 50/50

ambient 62*

cold truck engine off IAT2 was 62*

started truck did a few laps around the parking garage with 2 second bursts of maybe 4 to 6 pounds of boost kept this up for about 3 minutes.

IAT2 was then 102.

parked truck, shut off engine, within 3 minutes IAT2 was 148.

stock HE with a JLP street IC tank.

Whose blower are you using?

stock non-ported eaton and a 2# lower

Hmm, sounds like an area that the Cool-FLow could be very handy....90* ECT Temp drop in less then 10 minutes...:smoke:

Does anyone have a link or info about the H/E fans?
Thanks

Summit, Jegs, etc.................

Sport truck direct also.

Troyer has real nice s-blade fans, they are custom spec'd Derale units.

This was what I saw on the non ported Eaton with 15 psi and an open filter. This is from 2 years ago. It was August and extremely hot and humid.

Ambient temp was about 98*

The truck was already warm and @ idle for about 5 minutes before the run.

about 12 sec @ WOT

begining intake temps @ 149.3, at the end of the run it logged 121.2
IAT2 temps were 115.9 and ended @ 156.0

This shows that the high spinning non ported Eaton was producing a ton of heat. It also shows that an open filter under the hood with no shield drags in a ton of hot air (149 degrees) and still pulls in hot air at high speeds (121 degrees).

This test is good and bad....It's a bad day if your lookin for low temps from your truck but a good day to show how much heat my truck was dragging in on a hot day.


Now last year on the new set up I logged a little, a 91* July.
JLP power cooler 50/50 (no ice), KB@15psi, JLP CAI.

Ambient 91*
About 12 sec at WOT
Idle a couple minutes then the WOT run (truck already warm)
intake temps 102* at begining of run. Intake temps 93* at end of WOT.
IAT2 temps 108* at beginging of run. IAT2 temps ended at 123*.

I thought this was good evidence that sitting still and low speed (<5mph) the CAI still allowed a little warm air over top of the box, 102 on a 91 degree day. As soon as the speed begin to come up, the temp dropped back to 93*

The KB started at a lower temp mostly due to the CAI and power cooler but still climbed 15* over 12 sec.

I cant find my file on the ported Eaton but I do remember that with no other changes the IAT2 temps were down by a fair amount. Still using an open filter on that test.

Here is the solution for high IAT temperatures :

KILLER CHILLER

Too much work!!

What did you see complicated here ??? The KILLER CHILLER is made by the company of one of the most respected guys of the mustand community.

KILLER CHILLER

I am working on getting a Killer Chiller soon.
