well i want to do a cam and cant decide what one i want to use. i wanna get the most out of this upgrade so that means the biggest cam i can fit without fly cutting the pistons. also i would rather not do valve springs too but if its a must i probably will. how hard is it to do valve springs in the truck on these rigs? anyways let me know what ya'll think and where i can look at these things.
 
Helix 2 is a good cam by F-1 Diesel. The valve springs are a lot easier to do than the cam. Good luck!!
 
is there any places i can order a helix 2 cam and the valve springs in sort of a package deal. maybe even a tdr discount
 
Almost no HP will be gained. Maybe 50lbs tq, but it will help turbo spool-up by about 200RPM, and frop EGT's about 200*F.



The EGT reduction will allow you to stay in it longer before the EGT's get too high, and the 200RPM earlier spool-up will bring the power on sooner, and decrease smoke.



I did a Cam and Head at the same time and it helped tons! I can run 50Lbs boost with my twins, WOT with the Water temp slowly climbing, and EGT's staying at 1,275.



That's O. D. , 2,200RPM, pulling a good hill with 19K in tow. Takes about 4-5 minutes of 40PSI+ to get the water temp from 190 to 225*, then the truck de-powers and goes into limp mode to prevent overheat, still runs 30PSI.





I would do it if you are going to spend some money anyway. I have a PDR head, and PDR cam, but I've heard the Helix's might be better. Don_M is a great guy, and I would have bought my cam from him, but when I did mine, Piers' was the go to guy.
