These types of records have been done with AED as well.
However, this is not your average run of the mill 5.0.
No seats, no mufflers (good amount of weight reduction), race gas, full exhaust, aggressive tuning, etc.
I think it is impressive, but, I don't see your average joe running these times.
This is a low-mid 11 car at full weight, without slicks/skinnies and the amount of weight reduction they have.
Its actually a 10.9 car at full weight...
10.9 with our NA 2018 GT 10R80 with E85, long tubes, corsa sport, 4.10 gears, and the STOCK AIRBOX. All done on factory suspension.
The 10.88 pass is with mufflers droped and interior messed with.
Naturally aspirated with the Stock airbox, Stock suspension, drag pack, long tubes, e85/FTW mix, no mufflers, no seats, and 4.10 gears.
Unless they failed to mention no seats for the 10.9....they didnt drop the mufflers until AFTER they cracked 10s.
