Cobra ZR1

Very,very nice set up.
I like this set up.
Maybe next summer with a Kenny Bell Two rotor Supercharge.
But with this set up , is it not possible for me racing at different track.
My class is naturel aspired .

This is your old set up?
With a supercharge ,do you have some problem for drivability and other problem ( heating ) ( knocking ) etc...

since you have to stay NA in your class, then get the accufab throttle body. do you have underdrive pullies? how about ignition? I had the msd dis-4 on my cobra.
about supercharger drivablity....the car was my daily driver. no probs at all. didnt overheat, or knock. it was a blast to drive. i would stay away from kenne bell on their 96-98 dohc supercharger kits. they arent very good, and they dyno horrible #'s. im not sure why, because they make great superchargers for 03-04 cobra, and 99+ gt's, but for some reason they results are less than ok on the 96-98 cobras.

Well, what year car is the engine from? It would make sense for him to get a KB because he wants more power down low, where a KB shines. While at the track he may run a tenth or two slower, he would have a blast on the street!

if hes auto x'ing, he gonna always be high in rpms. plus like i said, the kb on the 96-98 are pathetic.

Roots style like KB or Eaton is the solution to your low end torque problems.

callmecobra

kenny bells arent roots. they are twin screw...but you guys are listening...the kb's are great, just not on 96-98 cobras. they are pathetic. i dynoed 460rwhp wih my vortech s trim with 8 psi....with the exact same setup on other cars, guys are doing 380-390rwhp. they suck ***.

A good engine setup is all about part matching. A KB is designed for down low power, where a NA Cobra motor is designed for high rpm power. You mix the two and you will have mediocre performance everywhere. If you want to supercharge a high rpm car, the only way to go is with a cintrifugal - like nomo already said.

All your information are great.
If next year , I upgrade with a Vortex Supercharge ( Best for a high RPM engine ) " good for me.
Do you have a big difference with or not " accufab trottle body " with Vortex Supercharge.
If yes I can upgraded this summer with " accufab " and next winter a Vortex Supercharge.
Only if Regulation Race accept this modification.
Because this year., all fan 427 Cobra ,not love my car.
My car is fast, very light,& with a incredible powerband .
