Westech’s Steve Brulé also pulled out 2 degrees of timing between 4,000 and 5,500 rpm, where maximum torque occurs, to again keep us out of detonation.With that tune-up, the engine pulled out 644 hp at 6,500 along with a best torque of 546 lb-ft at 5,900 rpm.

By the time we realized this, we had no time to make a new mounting bracket (see the “When in Doubt, Adapt”).The water doesn’t put out the flame, as is the common misconception.Instead, the small amount of injected water reduces the peak cylinder pressures that contribute to detonation.It’s a recurring theme from which we just can’t seem to escape.We discovered an iron 5.3L truck engine on Craigslist for 0, handed the owner three bones, tossed the greasy long-block in the back of our trusty GMC pickup truck, and headed for the barn. With a set of RHS heads, a Comp hydraulic roller, an Edelbrock intake, and a blow-through Holley, the Pro Charger huffed and puffed to 605 hp at 6,200 rpm.This does add length to the overall engine package, but Pro Charger says the company has already fit these blower packages in early Chevelles.

Water Injection The big issue with making boost is that it also adds heat.The one-two punch of heat and added cylinder pressure makes it very difficult for pump gas to control detonation.One solution is to inject a measured amount of water into the inlet system when the engine is under boost. The simple side of this concept is that during the conversion of a liquid to a gas, heat is absorbed, which lowers the inlet air temperature.This is the same concept your body utilizes to regulate excess heat by using sweat to pull heat away from your skin.In your engine, the injected water cools the air and makes it denser (a greater amount of oxygen in a given space).So we punted and used an aluminum block 5.3L motor instead.
