I went with the Southwest group to MTI today for Dyno day. This is the third time to the Dyno for me. The first time was at 1100 miles. The second time was at around 4000-4500 miles. Today, the car was at ~6700 miles.

In both previous pull, the car dyno'd within 1-2 HP, with two pulls per trip. This time the only change was to remove the factory cover from the airbox. I left the frame in place (including the center section). I used two tie wraps in place of the factory metal straps.

After my two pulls on the dyno I walked over to Jayson @ MTI and he said. The car made a strong pull. I asked him what it came in at. He said 372. I said that wasn't bad for an uncorrected number. He replied that that was the corrected number. I was more than a little suprised.

The two runs were 372.7/363.5 372.8/362.0 HP/TQ

Folks had complained before my run that the correction factor was off, because their cars were dyno'ing too low. The folks who I heard from before me were claiming to be low by about 5HP. Jayson checked his weather station before my run, and it appeared to be right on.

We pulled up my last dyno pull, and layed it over the one from this time. Across the board the open airbox pull was ahead. The two runs we looked at were 356.9/352.1 vs 372.7/363.5 My correction factor in both runs was .95. Weather conditions were almost identical.

My uncorrected number for those two pulls were 388.9/377.6 and 389.8/379.5

No magic, no tricks, nothing. The Stock airbox just simply seems to work pretty darn well with that restrictive cover removed. I am waiting to hear from Blu-By-U his car is about the same setup, but he has a Vararam. It will be interesting to hear how his car did. I left before he ran, since it was going to be well over an hour before they got to his car.

Awesome numbers.

I wonder what you'll run in the 1/4 mile now? Thats gonna be crazy... Maybe low 11s?

Was this with or without a K&N filter?

My 11.617 pass was made without the cover on. So, I don't see any more major improvements in ET. Weather will be the only factor to improve things. A good cool day, low humidty, high barometric pressure... A day like that will be a day for some 11.4-11.5's...

I still have the original paper filter in the car that it shipped from the factory with.

Chicago Z06

Never tried that on mine.. i too have the Vararam.. should have stayed with the stock and that lid mod.. we were doing that in 98 when the twin tube was all the rage... noting beat the factory with no lid and a tied filter... the facotry filter made more power then the KN as well...just couldn't get past the ram air marketing.. LOL... congrats J-rod... you are definitly one of the hottest Z06 drivers out there...

I am thinking about ditching the Blackwing and re-installing stock box with cut lid. Can you help a brotha out?

J-Rod

Sorry, I hadn't checked this thread, but if you need help let me know. I will help you out any way I can. Especially with the blackwing. Folks seem to have had issues with them in Z06s...
