Hi all,
Just thought I’d share my results from tonights Street Heat event at Bradenton Motorsports. Showers in the area, which resulted in high humidity, low barometric pressures, and generally higher temperatures around 8pm. I only ran twice, as it eventually rained out within an hour and a half being there.
The density altitude was 2872 feet in effective elevation, the national weather service says 89F, but my car temp gauge said 93F, and IIRC weather.com says 91F, so I’m not sure which one is 100% accurate based on my actual location. My mods are the same as before aside from finally upgrading my S/C cooling system:
GIAC stage II RACE file
GIAC TCU
AWE-tuning s/c pulley
JHM O/D pulley
Chipwerke Pro set to 3-1
AWE coldfront w/ upgraded pump
034Motorsports intake tube
aFe filter
2.5" drilled airbox
exhaust x-pipe
My fuel was 1/2 tank of my usual 93/e85 mix. Tire pressures were 39f/38r on Michelin PSS, spare/jack all intact in the car, so essentially no weight reduction. I did NOT utilize launch control, but used “primetimes’” method. I also have a larger custom crank pulley on order waiting for its arrival and installation, hopefully I can reach my goal once FL weather sees high 50’s/low 60’s this fall before installing that larger custom crank pulley.
Breakdown of my timeslip:
reaction .151
60ft 1.627
330ft 4.749
1/8mile 7.355
mph 94.47
1000ft 9.594
1/4mile 11.490
mph 118.98
With my current set-up, it looks like I may be able to run 10.9x-11.0x based on online calculators in “perfect” conditions and considering being able to run full advance in lower D/A’s. As such, I’m VERY VERY VERY happy with this time considering it was done in 2872 ft. density altitudes in temps between 89-93F (typical FL summer day, with high humidity). I’m also excited that I finally solved all of my WOT upshift issues, previously it would pause/hang for a split second on the 3-4 upshift with the Chipwerke set to 4-1 (up to .16 seconds recorded on logs on my 11.2xx second runs), I have dialed it down to 3-1 and now the hang-up hardly exists in logs.
