    What are the crank and supercharger pulley sizes on Hellcat?
    Is the crank pulley similarly sized as the Eagle and Apache HEMI?

    The crank pulley can be changed, ATI has a 5&17 % OD unit they are working on, not yet released for sales, the blower pulley is going to be much harder to change, if even possible....

    So, Hellcat Crank Pulley is considered an OD compared to 5.7 and 6.4?

    Totally different, a brand new unit for the hellcat which ATI is making the OD unit for.

    I just went to Diablosport website and this what I noticed in their 2015 catalog. They are listing 6.2 L for the T-1000. I have contacted Diablosport and waiting for an answer.

    I wonder what the asterisk is for by the 2015 on the Diablosport list. Maybe "projected for future" once they crack the code?

    Hi Rayzazoo,

    You are 100% correct. Mikel from Diablosport told me that they had to distribute their 2015 catalog so the 6.2L tune was a projected tune once they crack the code.

    What will you do with the extra heat generated by higher boost pressure? Will the stock SC intercooler be able to handle the extra heat so that the density of the air can be increased as intended? May end up generating more heat such that higher boost pressure does not add all that much HP. I am interested in seeing the result.

    Shouldn't need a tuner since they have MAF sensor. That should adjust for additional boost. Additional rpm would help but will need the tuner for that. I'm more concerned with traction at this point! Extra boost will come later.. Spinning ain't winning.

    This is true,,, but when you roll into the throttle the extra boost will help, just not sure how that clutch thing inside the pulley will work / or what will happen lack there of it..

    I think this is true to a point except for the 2nd throttle body that acts as a electronic boost controller.
