·Good news and bad news. First a brief explanation (no excuses-just the facts).
R&D Dyno has been an excellent dyno to get consistant numbers on our test vehicles for over 2 years now. Steve Cole personally uses this dyno facility because of this factor.
A few weeks ago, Darren regreased the dyno bearings and put everything back together. Then it happened.
His stock Honda, which has always dynoed at 109 RWHP suddenly lost 7 RWHP down to 102. No matter what Darren did, he could not retrieve the kind of stock numbers he could lay down prior to his DynoJet maintainence.
Many others noticed fairly dramatic differences when dynoing. Some who had added mods that normally added 20 or so HP were seeing only 8-10 RWHP.
Enough said, but the numbers recorded for this 2002 are way low in my opinion, even lower than the stock 2001.
Bottom line: The dyno numbers can only be used as a comparison of stock to another mod, or mod to mod differences, but the Max Power and Torque are off by as much as 5% according to Darren. At 5800 rpm the SideWinder really Kicks Ass over stock: 350.8 .vs 335.5 or a gain of 15.3 RWHP (18 flywheel).
The stock torque drop at that rpm is 298.6 lbs. ft. .vs 312.3 or 13.7 lbs. ft. difference
Monday we will dyno at another facility, just to verify these numbers.
HERE'S THE GOOD NEWS: THE SIDEWINDER ROCKS!
We started with the SideWinder, hood closed with the fans directed at the Z06 airvents:
Best pull: 350.9 RWHP/344.1 RWT
Installed the stock box and allowed relearn, then best pull:
Stock with hood down: 337.6 RWHP/333.6 RWT
Reinstalled the SideWinder with relearn time, Best Pull:
351.4 RWHP/344.2 RWT. At 5300 RPM, the SideWinder outpulls stock by 15.8 RWHP and 15.6 RWT (+18.6 HP & 18.35 Torque)
Correction factors 1.00-1.01
SideWinder made +13.8 RWHP Peak and +10.6 lbs. ft. Peak torque over stock.
(+ 16.2 Flywheel HP and 12.5 lbs ft. torque)
If GM's BHP numbers are to be believed, then we now have 421.2 BHP and 412.5 lbs. ft. torque just by adding the 16.2 HP/12.5 torque to GM's 2002 numbers.
If you use the 351.4/344.2 numbers that works out to 413.4 RWHP/405 torque for the SideWinder. (.85 correction factor)
I will post all dynos here next week, after the rest of the dynos are complete.
