It already is turbocharged. I am talking about twincharging it in order to get better boost response and a more square torque curve. Basically it will not only give me better off boost response (because with a positive displacement supercharger you are never off boost), but it also would spool up a turbo the size of your T61 about as fast as the stock T25 on my engine.
Originally posted by -defi-Eagle Talon? why not just turbocharge it? more kits available, much easier to install, adjust boost. and less money spent down the road on upgrades.
End goal I am aiming for "daily drivable" 600+ HP from my 2.0L. The GT3788R will spool up just shy of 6,000rpms on my engine. How well does the quick spool valve work for you guys? From the dyno charts they show it looks like it only offers about 300-500rpm savings on spool, which is awesome, but not enough for what I want. At best with just that turbo and QSV I would be getting full boost at 5500 RPM. I am aiming for full boost closer to 4000rpm and anything lower would be a bonus. I am not building the car for drag, but more for track days and daily driving where peak HP numbers dont mean anything, it is the broad powerband that counts. That is true. So do turbochargers through the backpressure the turbine creates. Turbos just dont have that mechanical link to the crank that superchargers do.
Originally posted by -defi-??? what kind of horse power are you looking for? if you want more response and power just save yourself the hassel, get a t4 DBB turbo with a divided housing, a manifold with an (UNDIVDED) HOUSING and install a QSV. super chargers take power to make power.
