"Project Demons Breath"

Put ChallengerFest on your schedule for 2020. It's the best place to see a lot of different combos on the same track same day. It'll be at Beech Bend Raceway in Bowling Green, KY. I'm working out dates with the track now but looking at the end of April or early May.

I will put that on my calendar. The closer to may the better . Due to snow I usually don't get my car out until at least may . But we will see how it goes next spring . It only 11.5 hours from my house . Not as bad as I thought .

We usually have a few folks from Canda attend. We used to have contests on everyone bringing their favorite beer until my friend brought the house down with some East TN moonshine LOL.

We should look at this last part since you and I are very similar.

I've checked a few logs from the track and here's some data to consider:

STOCK
In really cold temps like say 40 F the IAT was 69 degrees over ambient at 109 F after the burnout. This temp did NOT change from burnout to end of the 1/4 mile so there appears to be some minimum point the system will stabilize at.

In what I consider warm temps like say 80 F the IAT was 58 degrees over ambient at 138 F after the burnout. This temp ONLY changed by 4 F to 142 at the end of the 1/4 mile. In this case I actually had hot lap data to compare and on the THIRD back to back run the temps were 136 F and 140 F respectively so actually cooler on the third run and these were straight up hot lap right back to the staging lanes and go.

STOCK PLUS TUNE
Same day same track as the above stock data, I made some passes on a tune only from Mike@OST. What's of interest here are the increased cooling features implemented in the custom tune.

In warm 80 F ambient the IAT was 51 degrees over at 131 F after the burnout. at the end of the quarter they were 137 F. Hot lap (in the same log even) 133 F after burnout and 136 F at the end of the quarter.

2.4L supercharger with 2.72 Pulley = 16.5 psi on my car
In cool 55 degree air the IAT after the burnout was 111 F and 131 F at the end of the quarter mile so 76 F delta vs ambient compared to 69 F delta vs ambient stock. Not really that much difference considering the change in boost. This is with custom tune with improved cooling features however so compared to the stock with custom tune and same cooling features it's 56 F delta over ambient vs 76 F delta over ambient so say 20 F difference. Not bad considering the added boost.

2.4L supercharger with 2.72 Pulley on RE motor = 16.5 psi on my car
In hot miserable air of 93 F the IAT after the burnout was 126 F and 154 F at the end of the quarter mile with a delta over ambient of 61 F.

Another run in same hot miserable air IAT after the burnout was 140 F and 162 F at the end of the quarter mile with a delta over ambient of 69 F. This wasn't a hot lap, but not a cool down either. Staging lanes were crowded so however long it took to get back to the line firing the car to pull forward over and over.

Final run in 86 F the IAT after the burnout was 133 F and 154 F at the end of the quarter with a delta over ambient of 68 F. This run had a cool down.

With that data I think we can see the trend being that the SC cooling system sheds heat pretty well. My old Magnuson would get up to about 180 F in warm air at 15-16psi.

Curious what you see James with the larger blower?

I looked at my 9,86 pass from August 4 . The outside ambient temperature was 88F . At the end of the burn out my aircharge temp was 125.4F and at the end of the run it was 145F . I don't have the delta ambient temperature. . I will compare more later. I'm going to add more channels and rerun the tests for fun .

I must have been asleep on this. Hpindy is now on double secret probation and he doesn’t even know it.

Might be awhile guy just wrecked a new mustang man I’m telling you the track is roughy tonight
When ever I spin or break tires loose I just get out of it and cruise it oh and the car is pointed in the wrong direction

Nice!!!
And it looks like I wouldn't be able to beat you with reaction time. 👍

Was there a crowd of people standing where he hit the wall? Mustangs seem to autopilot themselves to the nearest crowd.

I usually cut a 001 but I’m slacking lol

I actually just rolled into it from listening hpindy I learned a little

I definitely can not take credit for the "throttle roll in" technique. That's all moparjim! It took him a few track days to get me to try it . The cave man in me kept smashing the pedal to the floor ! Lol

It’s sad but definitely driver error he is ok he was actually a friend of my buddy he said it broke loose in 2nd and he stayed in it

Don't know about the breath, but the critters exhaust smells like the Demonette's sister in law. Kinda good. Take that any day over than the Kat's. 4 legged critter, but I luv him better than my last vette's breath.

A little better

You cut another killer light and get your 60' into the 1.4's your running with guys in the 9's. Heard it was real hot down south today. I thought news said Virginia got to like 95 today. You running 93 or race gas?
