TURBOCHARGE or SUPERCHARGED - The $64 Question

[2FastCobra]

Here is a Good Forced Induction article http://www.snowperformance.net/produ...le-pdf-106.pdf . Turbo is the way to go!!! I have put superchargers on many different cars over the years, I have had Vortech's, Procharger's and 2 Kenny Bell units, none could compare to a properly sized turbo. I went with a turbo on the Cobra to help quiet the exhaust down and for the power. One thing that some are forgetting is that turbo's are dependant on load to make power, with the low weight of my FFR the turbo self regulates its power, if the car is moving well at 600rwhp in the lower gears than the turbo will not be under as much load and will make only the power that is needed to keep it moving and as the car gets into the higher gears (more load) and starts meeting more wind resistance the turbo will start making more power. In first gear my 2,270 pound car makes around 7-8 pounds of boost, in 2nd gear the car makes about 11-12 pounds of boost and 3rd gear up the car is under more load and will make 20+ pounds. Turbo's like tall gears, I am running 3.08 rear gears in my car, it is not to loud and with all the torque the turbo makes the car is always in the sweet spot. With drag radials and a well set-up suspension the car has very little wheel spin. If you have good traction at the track and are loading the turbo you will be making more power. Superchargers are rpm dependant and will make the same power in each gear as the rpm climbs. I am able with my turbo to make over 850+ HP on pump gas (injecting a little methanol). My
My car is making 924rwhp, 986rwtq at 18.3 psi, I am running 22-23 psi now and it is a blast to drive. Here is a link to my you tube dyno video. Dyno tune with Steve Petty.wmv - YouTube
Any power adder that is used on these lite weight cars will blow your mind!!!! Good luck!!
