I had ARH 1-7/8 installed with catless xpipe here are some before and after dyno results and a 100shot dyno pull.
this is a 2001 z06 so 385hp/385ft lbs engine in 2001

so base run includes my volant ram air filters, borla axle back and granatelli spark wires.
tuner told me the car also had been previously toyed with and had 2 degrees advance from stock.

these are whp numbers

base line was : 335hp @ 6200 / 355ftlbs @ 4500
tune with headers : 367hp @ 5700 / 372ftlbs @ 4600
100 foger shot : 439hp @ 5700 / 460ftlbs @ 4161

car has over 300ftlbs as soon as 2700 rpm

seen some bigger numbers on other forums but thats not the poing of the tune its about the gain.
im making more power earlier and i can feel it.

Seems a little low, but nothing too far out of the ordinary. I'm hoping for close to 450 whp, but Champion's dyno reads low so we'll see what it comes out to.

He must have pulled some timing out. It shouldn't peak 500rpm earlier after 1 7/8 headers. It should be good and safe though.

online people are closer to 480 hp on a 100 shot but then again every dyno is different, maybe a plate system would produce more hp.
we did a 15 minute street drive to make sure everything was ok with my regular driving style, never went over 0.3% difference in values between his target map and actual reading on the road so his dyno must be very well calibrated.

the car did already have a 2 degree advance over stock so he only had so much to play with and yes he pulled timing off on nitrous.


im bringing my car in thursday to get the tranny done and im installing a mgw shifter so the 1/4 will tell how much i have gained. time to beat is 12.16
