Ported Eaton Vs. Whipple

[TEABG]

did you actually see 13psi though? with the 3.5" pulley I got 15.5psi and gained 95rwhp over my eaton with a 2.76. My fuel system held up, but my MAF pegged 5v at about 6300-6400rpm.

14.5 PSI with the 3.5" pulley, my MAF did not peg becuase my tuner did not pull past 6,000 RPM because of the A/F ratio was on the incline fast past that. After I install the 60 pound injectors I will retune the car. I have JBA Headers on the way so that will reduce the pressure. 98 RWHP gain at 6,000 RPM so my numbers will improve with 60 pounders and we will see the outcome at 6,500.

:shrug: Seems odd you are only making 485 RWTQ. Perhaps there is something I do not know but I figured the HP and TQ number to be alot closer together. The Whipples sure must make alot of TQ between 13 and 17 PSI. People running 17psi are averaging between 570 - 590 HP and TQ.

With the Eaton I was 19 Deg timing and 11.9 A/F, The Whipple is tune 11.8 and 18 Deg timing. California 91 octane so safe is better than grenade. Even though my tune reduced the timing I still saw a significant improvement in torque. My mods are Cat-Back, Tune, direct blower swap WHIPPLE PSI-PSI. For a direct blower swap my numbers are simply impressive. Want to see dyno info, before after ? Not only did the peaks blow my mind but the mid range improvement WOW !! The RPM in first and second blow by like the car is jacked off of the ground. The whipple will put consistent PSI through the entire rev range.

19* Timing and ~11.5 A/F until the MAF pegs, just a shade under 15.5psi
