I doubled the fets on my Twin 2RBO-4, and I can only tell you this:

Using the same motor, the torque and top end increased improved DRAMATICALLY!!

With just one turbo, the acceleration of the same motor was fair, and the top was good.

With double FET Twin Turbo-4, the car got very Zippy, and the top-end was CRAZY.

DRAWBACK:: My car was glitching like MAD!!!

I messed up one other Turbo by doing this. It was all worth it though. I recommend it, if you have two turbos.

What kind of FET's are used in a Twin 2RBO-4 Turbo? Did you calculated the new internal resistance of this turbo?

I removed a set of fets from another turbo that's identical.

as for the internal resistance, it was no motor limit before. According to my calculations, it is now no motor limit2 (squared)

Honestly, I don't know what the new lowered internal resistance is, but it made a HUGE difference in power delivery in all power spectrum.


I conclude that it's the electronics that make the mini Z's slow machines.

what do you think is the 'cause of the clitching?


I want to try this...but the glitching....

I wanna try this too but the glitching!

hmm... a guy at the track tried resoldering the fets on the gpm super turbo... and whala... the glitching was gone... a partial short during soldering might have been a cause... not too sure though... but might be worth a try... good luck...

:ö: have you replaced the stock capacitor of your turbo with a higher capacitance?, if you replace the stock caps with a higher than the stock caps value, it may smoothen the spikes that may be the source of those demon glitch!.;) -æ
