Need some help with a decision.
But the two main diffrences in my book is that the turbos will pull HARD!!! threw out the WHOLE!!!RPM range !!Where as a SC(Super Charger) will only pull when its in the engines RPM range. The SC's operating range is dependent of the engines RPM and it is ran off of the crank( Belt system),so in the upper gears its harder to build boost with a SC unless you put a way smaller pully on to give you boost in the higher gears, Trade off,, is more exsesive heat on the SC and you'll have to blow off the higher boost in the lower gears with a pre set BOV. Now, this is your pro charger, Vortech style blowers, which by the way sound GREAT!, youll definatly be heard coming with that whistle sound LOL Now if were talking Whipple or Magnasoun chargers ,,,,These will be & feel more like a like a turbo in a sense that boost will always be there for you and torque across the graph line!! Very Very streetable with power and it looks bad *** under the hood as well as having a whistle sound !!This was and still is my choiceof SC before i heard of the APS twin turbo,The only down fall to turbos IMO is TORQUE and as all builders know!!!Torque KILLS everything & anything!!!and alot of guys leave this out when talking about the two FI kits!! Turbos will max torque at 2500rpms all the way to 8000 RPMs, where a SC may be there for a minute untill the shift and the blower has to get back to its operating RPM before you have full torque again This is the way my builder exsplained it too me when i was deciding between the two. Because when doing a turbo ,you'll have to put more into the tranny/converter & rearend then you would a SC car if looking for major HP gains, so if thinking of turboing?? save alittle more money before starting!! Actually save alot of money if thinking of doing either
and i forgot to mention a total fuel upgrade as well,, if thinking of doing either ,,which can be handled with one phone call !!to either Lonnies performance or Nasty performance. Lonnies performance actually makes the double pumpers for Nasty!! Both are great guys by the way
