I had a chance to run my SRT6 in 3/4 standing mile event. Due to extremely short runaway the event organizers had to limit the track to 1300 meters so that there was enough time to brake.
My stock SRT6 went 239.44 km/h in that event. I was expecting to go over 230 km/h so I was happy with the result.

 

I need a time slip. I want to believe.

Odd.. I would think that is quite expected speed for stock SRT6. Why would it be difficult to believe ?
I had 7 runs and that was the best. For comparison CLS 55 AMG was running 248 km/h (modded or not I don't know).
My stock Viper ran 254.9 km/h
Heavily modded with supercharger C6 Z06 corvette ran 308 km/h
M5 BMW (F10 or F90) ran around 284 km/h (modded or not I don't know)

 

I'm sorry I offended you. Somehow in my mind it was 1/2 mile and now I see 3/4. Forgive me.

No problem, not offended. I was already thinking it must be the clear Finnish air that makes cars go fast.

 

Now after 2 years since my previous run in this 3/4 mile event I had a chance to run again.
2023 my crossfire srt6 was bone stock and it run 239.44 kph ~ 148.7 mph

Now in 2025 my car has Needwings Dual intake + Needwings Overdrive crank pulley kit (3-4 psi boost increase) + Needwings ECU tune (this is Eurocharged tune).
Feels significantly stronger vs stock form.
However the end result in the same 3/4 standing mile was 242.23 kph ~ 150.5 mph

I only got few mph increase in top speed at radar point so now I am wondering that could I be hitting speed limiter ?

I believe the factory limiter is 155 or 158 MPH.... Most aftermarket tunes eliminated the limiter?

137 mph in the half was my best. Nice run!
