    Cons - It ain't cheap....Just for the turbo/supercharger alone you going to spend around $2000-$3000, plus another $1000-$1500 for other supporting items and tuning. This isn't including what you need to do for the internals like crank, pistons, connection rods.


    Pros - When installed & working correctly = FUN!!!!

    There is an old and very accurate saying "It's not how fast you want to go, it's how much money it cost to get there"


    Turbos - work great for low end torque but peter out the higher you go in the power curve.

    Super charges - basically the opposite of turbos, the higher you are in the power curve the more HP it puts out.

    I comes down to what you want/like. Some guys love turbos while others love superchargers. Each has it's own unique setup and tuning.

    IMHO superchargers are a little easier to instal on our f bodies then turbos. With turbos you have 2 places to install them, up front near the engine is preferred over rear mounted turbos like STS.


    Here are 2 guys that have or going through a FI build

    Rear Turbos... I know, but it was coming anyway :)

    I think Jon spent around $5k for his pro-charger set up.

    I'll pm you a turbo setup that is on another site that looks promising.

    So a roots blower from Eaton pulls hard on top but has nothing off the line? That is interesting. These statements are very general and the only reason not true is that they can be made that way depending on the package.

    I have around 10K into my Procharger setup just in parts alone. I got everything though; Aster tensioner (upgrade over ATI's), good gauges (A/F, Vacuum/Boost, Fuel Pressure), Alky methanol injection system, FMIC, hardened push rods, valve springs, etc. on top of the standard kit which is like 6K new...which also doesn't include a fuel pump or injectors. I went with 62-lb/hr. Your stock injectors are 28-lb/hr as comparison.

    Low end HP/TQ will depend on what type of blower you get. A centrifugal blower, like a Procharger, builds boost as RPMs climb, so you have less torque down low. A roots-style blower will build boost much lower in the RPM range.

    I preferred the Procharger as it's the most successful and reliable blower on the market. Plus, with that much power it's already difficult to get traction off the line so a centrifugal style works great.

    I've had mine going on 2 years now (3 summers) and the car runs flawlessly. Tune is VERY important with FI.
    It's on jackstands.
