Turbocharged Small Block Build Super Chevy Magazine. You can throw a camshaft, a carburetor, and plenty of other catalog parts at your small block, but without some forethought without a plan your new motor is likely to be nothing more than a 1. Joe Alameddine is a man with a plan. Hes an engineer with Dana Engine Controls and works in the companys research and development center, so developing and implementing plans is what fills his day planner. Lily King Euphoria Book Group Questions more. Like many Detroit area engineers, Joe is a dedicated car nut whose off hours interests are hard to distinguish from his 9 to 5 routine. Hes owned plenty of fast street cars over the years, and when he decided to boost the performance of his 9.

Although the engine is intended for a late model Impala SS, its not based whatsoever on the cars original LT1. Accel Calmap Software' title='Accel Calmap Software' />So, with a stated project goal of, in his words, 1,0. SSs horsepower was going to require some serious boost. Like, 2. 3 pounds worth. A power adder was definitely going to be required, Alameddine says. Turbocharging was selected because of the exemplary mass air quantity it produces, without sacrificing efficiency. Of course, building a 1,0. LT1s intake and exhaust systems. And with all that extra air coming into the engine, a few more cubic inches for a total of 3. Another goal of the project was driveability. By topping the engine with an electronically controlled port fuel injection system, Joe was able to do field development on his workplace project, Accels new Calmap 2.

Follow along as we build a 1,000hp twinturbocharged 383ci smallblock Chevy engine to install in a latemodel Chevy Impala SS Super Chevy Magazine. Dana owns Mr. Gasket Co., which owns Accel. Small world, huhThe small block has been punched and stroked to 3. The foundation is a stout four bolt main truck block. Ever the engineer, Joe outlined the engines process for performance before a single main bearing cap was torqued down. That process included increasing the engine knock tolerance threshold by creating a longer dwell time at TDC to promote 9. Calmap 2. 00. 0 software to improve emissions, maximize horsepower, and ensure driveability, and increasing the cylinders volumetric efficiency with the intake manifold and combustion chamber designs. Along with these process parameters, Joe was very careful with the selection of the turbos compressor wheels, housings, and intercooler. And to improve the engines overall efficiency, reflective and insulative thermal coating were to be used throughout the motor, turbos, exhaust, and intercooler. A forged and balanced Callies crank serves as the base of the reciprocating assembly. It provides the necessary 3. Mallory was used for balancing the crank, as keeping vibration to a minimum is a must in this high pressure motor. The Bottom End. With the plan in hand, Joe turned to noted engine builder Brian Thomson and his Detroit shop, Thomson Automotive, for machining, balancing, and block blueprinting. Thomson has years of experience building race engines, as well as contracts with General Motors and Ford for engine development work. Thomsons in house engine dyno would prove invaluable for sorting out many of the turbocharged engines necessary tuning hurdles, too. Starting with a four bolt main truck block the two bolt main stock LT1 block was ditched, Thomson overbored it 0. JE. Attached to them are 6 inch Carrillo steel rods which, in turn, are attached to a Callies 3. Sagem View Software Update. The piston crowns were coated with Swain Gold thermal material, which helps retain heat in the combustion chambers. The coating also allowed tighter clearances during assembly, because the pistons dont conduct as much heat and, therefore, expand less. Because of the daily driving goal for the engine, not to mention its relatively lofty 6,2. Joe chose steel rods over lighter aluminum components. Another consideration was the tight tolerances needed throughout the engine to support the stresses of a highly pressurized engine. The longer, 6 inch rod length puts the pin closer to the piston crown, which reduces the pistons tendency to rock within the bores. The 3. 83 runs longer, 6 inch steel connecting rods from Carrillo, which increases dwell time at TDC and enhances the engines knock tolerance on pump gas. The longer rods also reduce the tendency for the pistons to rock within the bores, as the wrist pins are located closer to the crowns. To shore up the bottom end, Thomson Automotive had the entire reciprocating assembly internally balanced with slugs of Mallory. This added strength and reduced vibration tendencies. Diamond Steel main bearing caps and ARP fasteners keep the crank in place. Heavy Breathing. With the short block built with the sturdiness of a brick outhouse, Joe turned his attention to the cylinder heads. They would have to move a whole bunch of air at relatively low engine speeds. Air Flow Research anted up with a pair of CNC ported aluminum heads that feature 2. Swain thermal material. The valves measure 2. The intake valves are pretty standard stainless pieces, but the turbocharged nature of the motor required something stronger for the exhaust side. Inconel valves were used for the exhausts. They were necessary, Alameddine says. With exhaust gas temperatures in excess of 1,6. F, any ordinary stainless steel valve would deform from the heat. Low compression, dished pistons from JE are thermally coated to retain heat in the combustion chamber and reduce overall friction. This allows for tighter assembly tolerances. Tighter clearances lessen piston blow by, thereby enhancing performance and emissions. Swain Gold coating was used on the pistons dished crowns, while Swain PC9 lubricant was used on the piston skirts. Actuating the valves is a hydraulic roller cam and lifter combination from Erson, along with dual valve springs and titanium retainers. According to Joe, the AFR heads and valvetrain have proved to yield great flow characteristics and contribute to the turbo engines snappy, low lag throttle response. Acura Tl Manual Transmission Swap here. To keep the roller lifters from bouncing off the lobes at higher rpm, an AFR Rev Kit was utilized. Drawing air into the heads starts with an Accel Pro. Ram intake and Accel 1,0. The Accel throttle body is a two throttle blade design each measuring 5. There are bigger, 1. Speaking of pressure, this small blocks comes from a pair of TO4 S turbos that were modified by Innovative Turbo to incorporate ball bearing turbo spools. They deliver 2. 3 pounds of boost on pump gas. More thermal coatings were applied to these big hairdryers, which not only helped reduce temperatures, but also boosted their efficiency and reduced turbo lag, as well. Additionally, a pair of Turbonetics Deltagate wastegates bleed off pressure when all that boost isnt needed. The wastegates are electronically controlled from the cockpit, thanks to a setup from Turbo People. Air Flow Research supplied aluminum, CNC ported cylinder heads. They feature 2. 10cc combustion chambers with 2. Since the engine has a rev range of 6,2. Air Flow Research Rev Kit help keep it all together. Erson roller lifters and 1. A more conventional way to reduce the pressurized airs temperature, thereby upping its boost pressure, is the use of an intercooler. A giant air to air intercooler with sewer main sized inlets and outlets snakes around the front of the engine. In fact, theres so much plumbing on this engine including headers and induction pipes by Kooks that we had a hard time getting it all in for our photographs.
