Katech Video Seminar DVD's

Experts Fritz Kayl and Caleb Newman of Katech Inc., the primary development shop for Chevrolet and GM Racing and the builders of winning engines from Daytona to LeMans, along with Chris Gelineau, lead the way in teaching you how to:
  • Prepare GMs Gen 3 engines for higher output, greater strength and increased reliability.
  • Maximize production parts to make more power.
  • Minimize airflow restrictions for better breathing.
  • Understand the race secrets of the C5R Corvette.
  • Modify your LS1 to a Z06 Viper killer.
  • Weigh the pros and cons of LS1 vs. Gen 1 and 2 small block Chevy, and much more.
  • Master the Gen 3 engine by comparing it to its predecessors.
  • Increase the strength, function, and power of various Gen 3 engine parts.
  • Improve engine displacement using the alternatives identified in this video.
  • Create higher horsepower, flatter torque curve, and better drivability for your C5R engine using tips from this video.
  • Improve engine performance by accurately interpreting bore distortion, power consumption, and hp graphs from engine and chassis dynamometers.
Purpose of seminar:
? Session 1: Give history on the Chevrolet V8 engine, now a General Motors Corp. Engine ? Session 2: Discuss hard parts modification and purpose built parts for Gen 3 performance ? Session 3: Go through an off-road engine build sequence ? Session 4: Talk about the C5R AMLS Corvette Race Engine Session 1 ? History ? Evolution of the Gen 1, 2 and 3 engines. ? Similarities and differences between Gen 3 and Gen 1 engines ? Various Gen 3 displacements: LS6 2001 vs. LS6 2002 engines Session 2: Modifications and Parts to Prepare the Gen 3 for Higher Output ? Identify components to better the Gen 3 engine functionality ? Determine how to build strength to handle higher power ? Learn about the parts you can modify in the Gen3 for increased power, strength and function. For Strength and Function:  Forged Components - Forged components are typically used only in 7.0L applications.  Discusses the various forged pistons used to increase strength  Discusses crankshaft: it is replaced to get more displacement. Forged and billeted cranks are available. Moldex uses a ?cam ground? counterweight profile to add mass and avoid hitting the piston skirts.  Billet Main Caps ? describes the various characteristics of billet main caps. This component helps bolster the production case prior to the creation of a purpose built race case.  Replacement Connecting Rod Bolts - Use on center beam ? not offset like Gen 1; various connecting rods used (video shows rods and weights that are available). On-center versus Offset rod. Video explains technical reasons why not to use offset rods in a gen3 engine, connecting rod bolt, and talks about quality of head and main bolts and how they can affect engine performance.  Solid Adjustable Billet Tensioner ? Katech found that the Spring tensioner fatigues; they replaced it with the solid adjustable billet tensioner to remove the possibility of speed induced resonance  Valve Covers  Oil Pump Modification  Head and Main Studs For Power:  Displacement ? larger bore case (Bigger is better)  Ported Cylinder Heads ? Increase airflow; (the production case can be bored and re-sleeved to 4.100?. With a 4? stroke you can achieve 422 cubic inches). Video walks through the process for sleeving a production case.  Focuses on LS1 aluminum and LS6 aluminum w/63cc chambers  Computer Numerical Control (CNC) cylinder head porting allows you to take your best port and replicate it. Video walks through this process.  Video shows airflow charts from LS1 and LS6 heads.  Ported Throttle Body ? Remove smaller restrictions (also CNC ported). Video discusses how and when to use a ported throttled body (and its outcome: increases HP).  Valvetrain ? Get the air into the cylinder  Camshaft  Rocker Arms  Lifters  Inlet Manifold ? Take advantage of other factors like C5R heads or power adders  Exhaust Headers ? easiest area to focus on to make power with the LS1 Session 3: Building Gen 3s (power) for Off Road Applications ? Detail actual engine build - Step by step process of an actual engine build on a LS1, (using a 7.0 liter and a 5.7liter as an example)  Specification  Clear understanding of what the project is  (Video shows you how to read EDSP) Engine Design Scratch Pad ? EDSP ? define the engine?s major spec?s: bore, stroke, rod length, compression ratio, number of cylinders, firing order, deck height, cylinder order, etc.  Fits and tolerances ? video covers the values for various clearances you should maintain, including:  Main bearing clearances  Connecting rod clearances  Lifter clearance  Piston to valve/radial clearance  Piston pin clearance  Ring gap  Parts preparation - video covers the preparation of parts that go into the short block (cylinder case, crankshaft, reluctor, connecting rod and piston, race bearing, head gaskets, etc.); how to modify oil pumps for durability, cylinder head assembly with our CNC ported LS1 heads  Final Assembly - Thoroughly wash all parts, final visual inspection, assemble parts ? Video discusses pros and cons of various parts: Solid Vs. Hydraulic Roller Camshaft, Production vs. Hutton timing chain (and use of cloyes gear set is one part in fixing the slack that is found in the production/stock timing chain); alternatives to gain displacement - stroker crankshafts, resleeve the production LS1 cylinder cases, C5R race cylinder case ? Review Dynamometer testing and results. Testing of the engine: what results in greater hp  Tuning the Production PCM  Superchips ? easiest form of generic tune  LS1 Edit - best way to tune a stock pcm (as long as you know what you?re doing)  Specialty tuners  Aftermarket PCM: (very expensive) Magnetti Marelli, Motec, FAST  Header sizes ? video offers advice about: primary lengths, primary size, collectors, (sizing, style) and material  Read HP graphs from engine dyno  Read HP graphs from chassis dyno Session 4: C5R Race Engine ? Video discusses the C5R race program and strategies to compete in endurance races ? Air restrictor requirements the C5-R must meet to compete in the American LeMans series in the GTS category ? Strategy to compete in endurance races ? Areas explored in the search for higher horsepower, flatter torque curve, and better drivability:  High pressure fuel injection system - description  Knock detection - Bosch electronic control unit employs an integrated knock control module to dynamically detect and make appropriate adjustments in real time  Cylinder Pressure Testing - MTS RedLine CAS system  Camshaft/valvetrain  Bore distortion ? video shows isometric and layer views of cylinder 5 at elevated and room temperatures  Friction and parasitic losses ? focuses on cylinder liners, pistons, main bearings, and the oiling system; Charts showing power consumption of the C5-R engine with various sump; charts showing power consumption at reduced oil pressure and flow  Engine weight - Every engine component examined to shed 50 pounds. The C5-R LS1 is one of the lightest LS1 on the circuit. Engine parts divided into three groups: 1. Reciprocating mass - Pistons, wrist pins, rod small ends, piston rings, pushrods 2. Rotating mass - Crank, rod big ends, camshaft 3. Rest of engine - Cylinder case, liners, main caps, sump, ?etc ? How they redesigned the engine to be 50 lbs lighter (including rigorous parts testing)
