Small BUICK V6 Spooling a GIGANTIC 91mm Turbo

Early launch tuneup tests after the discovery of the n/m dt als, and before incorporating the later to be discovered afterburner augmentation. A 224cid Stage One BUICK V6 on alcohol using port Nitrous oxide/methanol injection to spool a GARGANTUOUS Borg Warner AirWerks S510-91mm turbocharger.

Discovery of the Nitrous / Methanol Drag Turbo Anti Lag System
After fighting with the installation of a larger turbo (B/W Airwerks S510/91mm), trying to find a way to quickly spool this monsterous sucker with an automatic transmission and a tight torque converter (in this paricular test, a 2,800 rpm torque converter stall speed), we finally stumbled across a very interesting tuning discovery. We've always used Nitrous to help quickly spool whatever turbo was on the car, but this is something different. This is more than just simply injecting Nitrous. This video shows the point where we had become aware that we had discovered a new type of turbo ALS (anti lag system) that we ended up developing further to become the Nitrous/Methanol Drag turbo Anti Lag System with Afterburner Augmentation. Probably the most significant advancement of drag turbo anti lag technology in the past decade, not to mention the advancement of the use of Nitrous with methyl alcohol (methanol) fuel. Our spool assist valve was not used in these tests. Through special engine configuration and tuning settings, oxygen is chemically passed to the Exhaust system without the need of having to cut the ignition to any of the cylinders, thereby providing a simple, ULTRA smooth and quiet turbocharger anti lag, or quick spooling system. This turns out to be even more effective than just using Nitrous injection in the more traditional manner to spool the turbo. This allows a small engine using a Nitrous/methanol mix to spool a large efficient turbo with a turbine side that will provide the much coveted crossover affect, opening the door to more radical turbo camshaft designs. Nitrous/methanol mixes have come to be known to provide sub standard hp levels for a given jet size rating. Particularly when large shot sizes are being used. This system recovers all of that lost rating in a very beneficial manner. This system does not use the common pop and bang als method so often seen in turbo drag racing today. It is much easier on the engine, Exhaust system, and turbocharger. This new turbo anti lag system was accomplished in spite of the fact that we are using a distributorless wastespark ignition system. Or, maybe because of it? I expect only the most adroit tuner to truly grasp the concept and significance of this new system. Warning: This type of turbocharger drag anti lag system is for the most skillful tuners only.

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 a 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 the fuel pressure and Boost gauges in this video would be inaccurate. 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 showing only 6 or 7 psi Boost due to the signal line leak.
