Default Chuck CoW DYNO RESULTS with the NEW CAMARO VARARAM!!!

Congratulations MIKE and VARARAM!

Sorry it took so long...I know it's been a topic of much debate here lately.

Here's my dyno results. I have the beta-test unit...Vararam "race" intake (requires a tune). Tuning was done by Chuck CoW. (Corvette's of Westchester in Ossining NY).

Both dyno runs were done last night on a Dynojet.

Baseline was done first...totally stock. Made 360hp/352tq.

We than swapped in the tune and the Vararam intake, and ran it again...some nice gains...peak 392hp/398tq. The highest gains (most impressively) were at 4200rpm....+46hp/+57tq

Here's 2 graphs...the second one has the #'s at 4200rpm's highlighted. Keep in mind this is still a test unit!

Great results! Like Mike said, all runs were last night within the same hour, No road test between intake and tune swaps. Right there on the rollers.

The bigger results are from our extensive street tune of the NEW VR RACE UNIT...To my surprise, the mid and top end of the RPM scale required almost no adjustment from the street tune, while (as we suspected...) the 3,500 and down area was a bit rich because the car was not actually moving and we didn't allow any time for the fuel trims to correct the calibration after the intake swap.

Had we taken the car off the dyno, and driven it for 20 mins, the trims would have kicked in with some correction and the low end HP and Torque would have improved nicely.

Regardless, the results were exactly what we were hoping for and I think that this unit is gonna find itself at the top of the COLD AIR INTAKE FOOD CHAIN just as the way VARARAM products dominate the Corvette world.

So far as I'm aware, the production unit is just around the corner and will absolutely be worth the wait!

What's gonna be different between last night's VARARAM results and the results you would see between the My street tune and the dyno????

Well, as I said earlier, the low speed TORQUE and HP should come up sharply after the car is street driven and the fuel trims get caught up cause the AFR on the low end was far richer than my logs of the street tune were. Another point to realize: While we're totally pleased with the WOT results from the dyno, you need to realize that this intake system is AN AIRFLOW MONSTER which gobbles up air the faster you go!

What that means is that your "REAL WORLD" results with MY tune and this intake system should improve on the top end when the vehicle is tuned at SPEED on the street.

STAY TUNED! for next weeks dyno results of Mike's ongoing progress with the addition of a set of AMERICAN RACING 1 7/8 LONG TUBE HEADERS and a CAT BACK system!

...AND BACK TO THE DYNO!!!




Stay TUNED!
Chuck CoW
