I’ve been playing with the online calculator for 0-60mph times, trying to estimate what a completed 818 will do. These are based on my 2006 2.5L turbo donor.

Sanity checking the calculator first with some known (tested) times and the results of the calculator.
Standard 2006 WRX
Manual transmission, AWD, flywheel power 169 kW (226hp), weight 1420 kg (3130 lb)
Tested time is 5.7 to 5.8 seconds, Calculator predicts 5.74 seconds, so that is good.
Sanity checking again, with a higher powered, lighter car – Say the
Lotus Exige S
Manual transmission, RWD, flywheel power 257 kW (345hp), weight 1176 kg (2592 lb)
Manufacturer claimed time is 3.8 seconds,
http://www.lotuscars.com/gb/our-cars...specifications
Calculator predicts 3.79 seconds, so that is good too.
OK, one more, even more power, and much, much lighter, the BAC Mono,
http://www.autocar.co.uk/car-review/bac/mono
Manual transmission, RWD, flywheel power 209 kW (280hp), weight 538 kg (1186 lb) calculated from the 520hp/tone spec in the article
Manufacturer claimed time is 2.8 seconds for 0-62mph, Calculator predicts 2.52 seconds for 0-100kmh, so this one is a bit out, maybe traction limited?
Now for the 818 ……..
818 with standard 2006 WRX motor
Manual transmission, RWD, flywheel power 169 kW (226hp), weight 900 kg (1984 lb) - (I think Erik’s ran 2090 lb with some extras) = 4.3 seconds
818 with “Stage 2” Tune and 2006 WRX motor
I picked this one because you’d have to try hard not to get this performance in a turbo 818, given we’ve got to mod the exhaust anyway….
Mods are 3” downpipe, K&N air filter in the standard airbox, plus a tune, adds 20 kW (27hp) at the flywheel,

Manual transmission, RWD, flywheel power 189 kW (253hp), weight 900 kg (1984 lb) = 3.9 seconds
818 with “Stage 3” Tune and 2006 WRX motor
Mods are VF34 or VF39 turbo, 3” downpipe, STI TMIC, GM boost control solenoid, K&N air filter in the standard airbox, plus a tune, now 212 kW (284hp) at the flywheel, same source as above
Manual transmission, RWD, flywheel power 212 kW (284hp), weight 900 kg (1984 lb) = 3.6 seconds
818 with “Stage 3 Race” Tune and 2006 WRX motor
Mods are VF34 or VF39 turbo, 3” downpipe, STI TMIC, GM boost control solenoid, Injen CAI, bigger fuel pump, plus a tune, now 288 wheel hp, so approx 340hp at the flywheel

Manual transmission, RWD, flywheel power 340hp, weight 900 kg (1984 lb) = 3.2 seconds
What will it take for a sub 3 sec time?
375 flywheel hp and some really sticky tires!
