The Easy Street Impreza from the USA ran a 7.9@165mph!
Torque converter was slipping like fuck for that run too, as its ran 174mph terminals with less power.

Going for more power already, now gonna run it on methanol and an even bigger turbo, low 7 coming v.v.soon.

Was running 48psi boost and hi comp on Sunoco race fuel.

Full-on drag car, as youd expect from anything capable of running a 7.
