Was wondering what u guys are shifting your super charged trucks at.I was wondering which valve springs are the best if shifting over 6200.I had my truck on dyno had rev limiter at 6200 but it still was pulling strong.The guy said i was snubing it off but i told him rather be safe than sorry...Made 543rwhp at 6200 still was going up but shut down...I have ls9 springs on now but thought maybe should do dual spring set up.Which ones are reasonable and just go on the heads w no mods..THANKS GUYS

 

I have lunati dual springs. 6600 Rpm's on my turbo setup

 

LS9 cam dropped in behive pac 1211x $170 quiet the way i like it 6300 shift

 

Crane extreme duty, 6200rpms.

 

I am running Patriot Golds and shift at 6200-6400, I have taken it to 6600 but prefer to keep it lower.

 

63ish

 

thanks guys i was gona run around 6500 6600 it was real strong at 6200.which im sure the ls9 springs can handle..

 

They will. Good for the price as well.

 

GT2-3 cam with LS9 springs, shifts points are set so on the up shifts the rpm falls to its optimum in the torque band, they all vary for every gear.

 

6600rpms with PAC1208 iirc
