Thread: Setup to go for?

it can be done, however it doesnt make much sense to do both since with a well setup turbo or m90 build would run pretty much as fast and wont be as much work to get running correctly.

If you twin-charge by keeping the supercharger, you must get an intercooler for under the supercharger (at least according to zzp). I don't know of any setups running twin-charge without the s/c intercooler. I have the zzp Stage 2 on my setup.

I don't think there is any reason to go twin-charged unless you plan on making huge power with a larger turbo. Our engines respond very well to just a small or medium sized turbo without getting the supercharger involved. When you start making huge power, you have to think about so many other things, like cam, heads, suspension, traction, and especially the transmission. Going with just a turbo will require a transmission upgrade. Most will say a 1" chain is a must, but since there are no more available, you will have to decide on whether to settle for the 7/8" chain, or look for a 1" on the used market. The input shaft must also be upgraded, and a billet flexplate and higher stall TC is recommended. Look to spend at least $3000 on just the transmission/flexplate/TC parts, unless you find a used one cheaper.

Twin-charge tuning is no different than tuning for turbo only. The only setting that you might have different is when to enter PE, as boost can start very early. On my setup I see boost as soon as 25% throttle. A lot of this will depend on the size of the turbo and the size of the supercharger pulley.

There are a few different options for the upper intake. Taking the rotors out of the supercharger and installing the block-off plate is probably the easiest. There is also the option of a custom intake like this:
