Folks, it has taken me forever to get around to this, but finally went and did some back to back comparison of the stock car vs. the Blackwatch Racing TB(2005) + Intake. As we've discussed in the past, putting an intake on makes noise but little power as it is going through the stock throttlebody. Its like 2 kinks in the same hose. You're not gonna get the full flow until their both gone.
So I did an A to B comparison between stock and with Airbox and Intake + TB. The results were not surprising, but favorable nonetheless. We picked up max of +10HP and +7lb-ft! Everything else is stock including exhaust. Didn't even port match the intake, which is probably worth a couple more ponies. You could feel the difference as it smooths out the cam transition and pulls harder from 5500rpm up. Finally something for the NA guys as well as FI guys.
This throttlebody is not a re-bore with paper thin walls. It is a fully cast part with pressed in bearings, beveled throttle plate, throttle set screw, and 70mm opening. Just pull off the stock TB, swap the sensor, and spring over, IAT control and you're done. It took me about 30 minutes.
Regular price is $695, for a limited time, we've got them on sale for $495.
