It made 406 rwhp (302 rwkw) on 95 pump gas at 18 psi going down to 17 psi. Yea i know, it's the best pump gas we have. It's either this or C16 racing fuel. And my car is a streeter, can't run on C16 all the time.

Hi guys

I think I am the first to post up the results of a Mamba brand turbo. The unit is fitted to my series 2 Stages RSFourS RB25DET-Neo. I took the plunge and contacted Eiji directly for my purchase and couldn't be happier. The dyno results speak for themselves, I will be sticking it back on the dyno to get the 300rwkw I was chasing, and it looks very achievable. Tuned by the wizard himself Dec's from Garage 7, he had to stop the tune early due to the clutch losing its ability to hold the power, a standard clutch was never going to cut the mustard. New clutch ordered and it's almost guaranteed I will be making a post in the '300kw unopened club' thread.. So, see below.
