People running this thing at higher power levels past 750 usually run meth, ice tanks etc. Its not just about HP numbers, its about efficiency as well. Hook up your hp logger, log your MAT temps and watch your timing get pulled all over the place. The 2650 isnt just about numbers, its just a superior blower with superior cooling abilities. Compare any build with the same engine mods, heads, cam headers etc. Only thing different would be stock blower vs the 2650 and look at the difference youll get in real world, not 2 pulls on a dyno. My stock blower in summer heat was a dog, 145+ F temps all the time or higher. The 2650 in 40F cooler and when in boost the temps drop, not go up.
If you can afford the 2650 its just a far superior blower then to mess with the stock heat pump.

I don't think anyone is questioning whether the 2650R is superior, no one. I think its just a matter of a person's goals and amount of money they want to invest.
My .02, stick with the stock ported blower until you max out the fueling, IF you need to go beyond that and need to upgrade the cam and any additional fueling, its time to swap the blower.
