For anyone buying those specifically to get a bit more top speed I would say - be prepared to do some serious tuning work - or save your money. In other words, yes, it will work but requires at least some tuning - beyond adding/removing the spacers. That involves adjustments to impeller pitch and sizing the venturi nozzle opening.Geez I'm so torn on about getting this in the offseason this year. It's almost like a crap shoot from my understanding of these trials and reports. You may or not get anything out of them. What to do lol
I'm not going to do this, as I do not find any evidence that the engines are starved of air at WOT. For example, there is no suction detectable on the fire extinguisher hole (in the engine hatch), and no RPM gain if one cracks the engine hatch open.Party pooper. Any experiment with cold air intake yet? Would that make much of a difference for low end torque?
Well, I guess it depends on a goal. If chasing top speed probably need to play with both.Is this a better mod than a new impeller set up? Or are the result different from both?
