those turbo razors are bad ass! we are in the process of designing two very affordable turbo systems right now...if you think race cars are expensive, you should see the prices on the parts for these!! so we are gonna make it way more affordable. also doing custom cages and some other stuff. these things are as addictive as freaking race cars!!...end of hijack,sorryMy buddy built a turbo kit for his razor...at low boost it made 89RWHP....It is a monster..We twisted the stock shafts on the first launch!!!
