The Ultimate Turbo Anti-lag System

A close up encounter with a new turbocharger anti-lag system that will soon change the face of turbo drag racing forever.
A 224cid Buick V6 spooling a monster Borg Warner Airwerks S510/91mm turbo.
These tests were performed with the afterburner set at a low initial setting. The full potential and limits of the afterburner feature are yet to be explored.
This system is very capable of pushing the 3200 rpm stall speed (no nitrous, zero boost) of this torque converter to over 6200 rpm stall speed in 2 seconds, and in the same time generating over 220 kPa manifold pressure. Impressive only if you fully understand the demanding spooling requirements of the Airwerks S510 turbocharger.
Pro light launch tests with the newly enhanced Nitrous/Methanol ALS coming up next.
Update: Latest performance of the car, 2/12/11, 5.57 @ 126 mph in the 1/8 mile. 1.27 60'. The ALS activated for only 1.7 seconds, and shut down before launching the car from the starting line.

In the comments section I have made entries that give detailed descriptions of how this system works and basics on how to set it up.
This system is far from optimized. Hopefully others will play with this system and make further impressive advances with it.
Warning: For Advanced Tuners Only!

Update: There was a substantial leak discovered in a tee fitting in the MAP signal line that, at the time of this video, fed both the fuel pressure regulator and the boost gauge. Trying to judge the boost level with those gauges in this video would be inaccurate. For instance, the boost level that was recorded by the ECM during these tests was in the range of 14 psi. The boost gauge in this video (upper left gauge) is only maxing out at 6 or 7 psi boost due to the signal line leak.

it was upset to see it was a buick at first but then....phew....that shit is just right

[DonW21G]

@mtxgsxr Thanks.

Have u dynoed it? If so how much hp is it making and what rpm do u make max tq?

[DonW21G]

@420evo420 I have not dynoed the car. Matching the time slip incrementals to a drag racing sim, the estimated peak BHP is 1130 at 32 psi boost. The fuel table is showing peak torque to be at 5700 rpm.

The nitrous/methanol ALS is evidenced by a flatline 1.0 lambda reading on the wideband O2 sensor. That's when you know you have the tune right.

wheres the anti lag? i see not anti lag system

[DonW21G]

@luciffer420 That's the beauty of this system. The burn of the nitrous/methanol ALS is so controlled, consistent, and efficient that you don't get the pop and banging like you get with the erratic combustion of the gasoline type ALS. The nitrous/methanol ALS is as smooth as glass.

nice gn
