I did a couple pulls today in my build, which has been running fantastic today for whatever reason and decided to let the interceptor do a HP check and on most of the pulls it read a max HP of 406hp @ 7300rpm in 2nd gear.... now I'm very familiar with cars of this range of horsepower and honestly it really does seem to be pretty accurate. I will be getting this thing finally up on the dyno after Daytona Beach 80th Bike Week is over, I'm slammed at work but has anyone else tested with their interceptor and then checked with a dyno? I'm guessing this build is right around 350-380hp.

also if you've ever had spark blowout or issues with your coils, I highly recommend ZZP coils, I love these things.... they even made my afterburn sound so much more poppier and meaner.

Very happy with this build, can't wait to put some numbers down on the dyno, tighten up the tune and then hit the track.

build:
2006 Cobalt SS 2.0 LSJ
TVS1320 with 2.9in Pulley
80s injectors
fuel pump rewire
ZZP 3in headers, ZZP 3in resonator, ZZP 3in muffler, ZZP 3in downpipe and 3in piping between it all (no cat but 2 O2 sensors and 1 wideband in their normal spots)
LS4 Throttle Body attached to stock intake with the intake mod done and K&N cone filter at the end
NGK 2 step colder plugs gapped at 0.027inches
ZZP Red Coils
E85
Dual Bypass Endplate
ZZP front mount heat exchanger
Option B routing (bleeder in the top of my stock heat exhanger)
ZZP Intercooler Pump

 

Probably around 350 or 360 seems right
