I HAVE A 06 SILVERADO CREW CAB AND I WAS WONDERING WHAT THE STOCK HORSE POWER AND TORQUE? I WAS ALSO WONDERING WHAT KIND OF HORSE POWER I HAVE: I HAVE A K&N INTAKE, FLOWMASTER EXHAUST, AND THEENERGY MAX PROGRAMMER. I WANT TO GO TO THE DYNO TO SEE WHAT THE TRUE POWER I HAVE. DO YOU THINK THAT I COULD BEAT A O6 DODGE CREW CAB. THANKS GUYS

your stock power to the engine is 295hp@5200 RPM. torque is 335ftlb @ 4000 RPM. probably take 15-20% off to get rear wheel power.
I have the same setup you have but in an ext cab. the dyno sheets from their websites state:
K&N: +11.92hp @5367RPM
Hypertech: 87 octane=250hpmax to rear wheels @ 5250RPM, 279lbft of torque max @ 3750RPM.
flowmaster maybe mutiply your base hp and torque by 5%.
i doubt you could beat a hemi but maybe. i still get smoked by Nissan Titans. but the 3.e42 gears dont help towing or draging.
what gears do you have?
i would love to know the results of your dyno run when you get it done.
2006 Chevrolet Silverado Ext. Cab LT3 VortecMax, Black, K&N 63 series intake, 40 series Flowmaster, Line-x spray in bed liner, SS Insturment cluster, corvette servo, Leveling keys & 295/70/17 Nitto Terra Grapplers. 93 octane blackbear Tune
I believe mine stock is 275, but only 245 or so at the wheels.
Not bad considering:
99 Ford 4.6: 230
99 Dodge 4.7: 230
99 Toyota (whatever their small V8 was before the 5.7): 230
But the Predator was the best improvement. I get 4% more out of 87 octane (11hp), 6% more out of 91+ with that alone (16hp). Then if I got another 6% with the intake, TBS and Stat, then I figure I have the potnetial for about 300 at the crank. Maybe 275 at the wheels.
99' Silverado 5.3 4X4
Modified Predator 93 tune: TQM @ 40%, injector slope bumped up 4 levels,
125 MPH top speed, 5500 RPM limit,
TBS, 180 thermostat, 4" CAI with 9x6" element,
Bypass and De screen performed,
AVG: 16 MPG City, 20 MPG Highway
wouldn't measurement be straight from the wheels only though?
to get nominal horsepower of the engine it self is simply:
nhp = 7 x area of piston x equivalent piston speed/33,000 (wikipedia.org)
therefore the dyno would only be measuring the HP at the wheels.
or am i out to lunch?
