Unless you are pushing well over 500Hp you may have trouble staying up with Rrocket and his car. I have seen him run and its very fast in the 1/4 mile for sure. His is built more for that style of racing I believe but probably would be good in the slolam style as well. Those twins turbo's do add a lot of boost in his. 
My telling rrocket that I would give him a run for his money was (mostly) tongue firmly in cheek! I can do the math:
Power to weight ratio (standard measures)
-----------------------------------------
My car: 155 bhp / 2000 lb = 0.078
His car: 320 bhp / 3486 lb = 0.091
I'm comparing against an un-modded Supra Turbo (source Wikipedia:

Factoring in my close-ratio five speed and my grabby twin puck Centerforce clutch and it might make things interesting for the first 100 or so feet in a drag race but I would be sniffing his exhaust beyond then as his turbos spool up and kick in.
I'd eat him whole in a slalom though! I know this because even before I modded my CRX Si with the Koni coilovers, adjustable perches and sport springs I was dining on Vettes.
Light makes right.
