Title says it all! Just got done with a upgrade to my paxton kit. I first started off with the Beefcake special with ID1000,stock pulley and a vortech BAP at 17.5 V. I then started dyno tuning on E85 and put down 730rwh and 521 ft/lbs. Raced a few people and met up with a nasty Kenne bell supercharged Cobra Terminator putting down some good numbers close to 650+ with 600 ft/lbs. It was way to close of a race for me ( around a fender ahead). I then wanted more but was limited by my vortech BAP so I tried switching to a JMS BAP at 21 Volts. This still was not enough and would leaning out above 7000 rpm and couldnt keep up with the HP I was sitting at so I had to turn to a return style fuel system. I got in contact with Dustin at CPR in San diego to install my JPC triple pump Y Block fuel system. During that time I wanted to boost up the Torque so I grabbed a Wastegate from beefcake along with a new Gates belt. Just got off the dyno with some interesting numbers. This was with a 3.33 Pulley and wastegated with the 9.78 lb spring. I have a Boss 302 intake manifold as well. This is the same dyno before and after.
Gained a LOT of mid range and Torque was way up. lost a lot of top end though. I wanted to give Dustin at CPR a big shout out for working on my kit and taking the time to get it all done even though he was busy working on his trans break system. Here are some pic of the fuel system we installed.
