how are the other 4 controlled? im sure perfect drivability can be achieved with the 60's.

very interesting...
I figured 60's with a bigger pulley would work rather than adding another set of injectors. For some reason, I thought it would actually make better sense to use 60's rather than another set of injectors.

how would a bigger pulley make you not max out the injectors? there is a freaking turbo pushing the air at higher RPM's, not the SC!!

use a 3.5 or bigger, you can scale them down...mine are set at 63.49 almost across the board. If I had a smaller pulley, I could drop that to 42 or maybe even 36.
I'll send you my tune tomorrow and you can see how I have the high it is. My actual duty cycle only gets to ~80% at 7100 rpm

But if your twin charging, your obviously trying to get more air using the turbo, so what is changing the pulley size going to matter as far as maxxing out the injectors. The maxxing factor will be the turbo, not the SC.

I am not saying getting a pulley that size will not help (less parasitic loss) but it will not make the injectors not max out in this circustance

Are more powerful (if that's the right word) injectors available that would be able to pick up the slack? Or are the 60's the best option out there?

Forgive me if it's a newb-ish question. I'm not that knowledgable about cars.

It should work, shouldn't it, you wouldn't need another set of injectors. They 60's could be managed with HPTuners, then the intake air can be diverted passed the SC blades using the bypass.
I'm following this line of thought because this makes sense to me. Unless my logic is flawed (which is probably is )
