Blueprinted Engine Series
All Engine blocks are blueprinted using a state of the art Rottler F-65 computerized boring mill. The blocks are sonic checked, core shift verified, magnafluxed, bored with torque plates, honed square - parallel decked, line bored and line honed. The cylinder bores are plate honed using a Sunnen CK-21 computerized vertical honing machine. All blocks are painted black. Cam bearings, galley plugs, and brass expansion plugs are installed. All blocks are milled to proper deck height. Threaded holes are chased to insure proper torque readings.
For an engine to perform the way you want it to, there is an important fact to consider. Quality parts. The parts you use bring out the personality of the engine. Performance requires the selection of the right camshaft that influences the way the engine performs. There are several important facts to consider when designing engines. This comes down to static compression ratios to maintain cylinder pressure therefore making the engine responsive and achieving good torque levels throughout the entire RPM range. Your can expect nothing but the finest workmanship when all of our years of experience in building racing engines allow us to design combination that are best suited for your applications. Making reliability number one!
The first step in creating a powerful engine combination is selecting the right camshaft. A camshaft with optimum complimentary lift and duration profile will ease valve train stress while maintaining maximum torque and horsepower. Our endurance engines use the Miller Cycle design featuring the following:
- Fast intake ramp for greater charge velocity.
- Long exhaust ramp - preventing the valve from bouncing off the seat.
- Long power bands.
- Increased seating for valve cooling and reduced valve train maintenance.
Our camshafts come in hydraulic, solids, hydraulic roller and solid roller profiles. Contact us for the proper custom ground camshaft which is best suited for your engine.
The main principal for supercharging is "Keep it Simple". Simply put, supercharging gives you more power for the dollar than any other induction concept. Supercharging forces fuel and air into the engine, increasing the combustion rate and intensity.
Superchargers are a belt-driven device driven off the crankshaft forcing fuel and air into the engine. This increases the combustion rate and intensity, which produces more horsepower and torque. There is a common misconception that superchargers are not reliable, this is simply not the case. Reliability can be achieved by selecting the Static compression ratio suited to your supercharged engine. Every pound of boost introduced by supercharging can get approximately 30 hp of power depending on the application!
Incorrectly matched components in supercharged applications can cost you valuable Horsepower and performance. Contact Southeast Performance Engines for information to get the most power and dependabilty out of your Supercharged engine.
Engines operate under varying load at all times, therefore they must be extremely reliable in the environment they run in. The following steps are taken to ensure your engine's reliability when ordering our Dyno'd Turn Key series.
- Tuning carburetor and setting mixture adjustments and float levels.
- Checking the engine for water, oil and fuel leaks.
- Setting valve lash adjustments
- Ignition timing and tuning the advance curve for total performance.
- Leak down test on engine cylinders to ensure all piston rings, intake and exhaust valves are seating properly.
For an engine to perform the way you want it to it must be carefully thought out for the correct selection of parts to bring out the personality of the engine. The whole combination must be properly matched to ensure the engine is efficient and maintains power throughout the whole RPM range.
Southeast Performance Engines utilizes only Top Quality Components to ensure top-quality and reliability. When designing a specialty endurance engine it is important that in the valve train department that careful steps must be made by using inconnel exhaust valves and race prepping the valve-train with 10 degree valve locks and titanium retainers. Competition performance valve jobs are performed on aspirated and supercharged engines to ensure proper valve seating, which helps the valve cool more equally.
Cylinders are machined and finished in a 820 plateau finish. This is classified as micro-finishing bore. This way plasma molly piston rings will guarantee seating and reduced oil consumption. This is advantageous because it increases piston ring life.
Extra clearances on connecting rods for increased oiling helps longevity for bearing life in high performance engines.
Balancing and blueprinting of the entire engine helps longevity and smoothness of the reciprocating assembly.
You can guarantee a Southeast Performance Engine will far exceed your expectations!
