Well.... I had a weird night at the track the other night. Temps and DA were similar to the last time I was there a month previous. Anyway, for the first time ever I put 3 gallons of 100 octane race gas in the car (it had about 7 gallons of 91 in it at the time). Drove it about 5 miles after topping off.
My MPH was off by a crazy amount for all runs. I only drove 20 miles to the track so I don't *think* it was heat soaked. I do not have a way to monitor IAT2.
2018 A10 GT w/ Roush Blower (street tires)
A month ago:
12.2 @ 123mph
Friday night:
12.7 @ 113mph
MPH was almost 10mph lower for ALL runs the other night. Not sure why it was so low. I find it hard to believe the DA or temp would cause a 10mph difference. 60' times were the same. *Could* temp or weather really drop it 10mph? Could the car not like the race fuel and it pissed the ECU off? All of my runs with the blower previous to this have been about 118 to 123mph.
Anyone have any ideas? Also, what should I use to create logs since I know someone will ask if I did.
Excuse my inexperience, first supercharged car ever. Time for a trip to dealer?
