The name says it all "Challanger"
Challange your driving technique, challanger your driving spirit, challange your NERVE.
when i saw this I had to give it a go, Im a fan o american muscle cars, and a racing spec dodge... just try an stop me.
First thought. Love the green, looks awesome. second thought. This thing is fun and sounds great. How can RKM top this. Well......
Right the review
as per my first post, done in "Top Gear" styles
No oil changes, no driving aids, just straight outa the shop with RC Hard tyres
Speed Run
0-100 Km/h 3.664 sec
0-200 Km/h 9.692 sec
Max G-Force 0.85G
Max Speed 309 flat, Maxed out
0-400m 11.266 sec
0-1000m 19.947 sec in 6th @ 6,800 Rpm
As im sure you'll agree, these figures really speak for themselves, quick isnt the word, standing quarter in 11 seconds, on cold RC hard tyres, with wheel spin at the start. Impressed.
Now for the time trials
Trial mountain: 1:27.433 Sec
(just faster than the brera, with the wrong tyres on lol)
Laguna Seca : 1:26.485
So all in all a really quick american made sports car with green paint and some stickers thrown on. still, works well and sounds fantastic.
Now for the RKM workshop to do their business
As before, no oil change, same tyres, no driving aids
Speed test
0-100Km/h 3.660 sec (not much difference really, just more wheel spin)
0-200Km/h 8.195 sec (difference of 1.497 sec)
Max G-force 0.85G (no Change)
Max Speed 344.8Km/h in 6th @ 6,900 Rpm
0-400m 10.750 sec (difference of 0.516sec)
0-1000m 18.711 sec in 5th @ 7,200 Rpm (difference of 1.236sec)
Not really much has improved, half second on the quarter, 1 an a bit second in the quick 1km run. however, that supercharger allowed the car to really start to pull away once she got moving, just need to sort out the wheels letting go at the launch.
Time Trials
trial Mountain 1:25.433 (difference of 1.889 sec)
Laguna Seca 1:23.319 (difference of 3.166 sec)
Now thats impressive, lets remember that this is a race car, so it was already setup for the track, but with the improvements that RKM have done, its turned into something special. almost TWO seconds a lap faster on Trial Mountain and over THREE seconds faster on Laguna Seca, Real drivers would love to have that advantage on the track. Dont think the marshalls would allow the supercharger though. But horsepower aside, this thing now turns in, holds line and bites the corners, just watch the throttle coming out of said corners, cause that supercharger comes in strong above 6,000 Rpm, so watch those low gear corners, cause she'll slap you faster than a fat woman called pregnant.
Seriously fun car though, a bit nerve racking coming outa corners, but still really fun, And sounds even better than before with that blower now onboard.
It's times like these where I'm glad we get people who want to test an interesting car and help us see things that we otherwise would've missed, so thank you. 👍 
by the way!) and it would be unfair of me to say otherwise.
Yes, there's no point improving on its speed. It's an American muscle car, it has speed out of the box. What it does need though is a good setup, which as you saw, improves lap times by a fair bit.
