How to choose Blue Print Engine

One of the most common questions for BluePrint customers is for beginners. Do I need a mini-starter? Or a high torque starter? Or will my old starter work? Before buying a new starter for your new BluePrint engine, you need to consider several factors. We will tell about them here.

First, we provide some information that requires a high-performance starter compared to a replaceable starter.


In particular, the starting time of the engine makes it difficult for the engine to rotate at start-up. For many racing engines, the ignition time is stuck at full throttle in the range of 35-40 degrees. Thus, many ignition systems in the aftermarket have built-in delay switches that significantly reduce the time required to start the engine. BluePrint engines recommended an initial setting of 16 degrees or less, which shouldn’t be a problem. Check your engine tuning before buying a new starter.

Valve spring pressure

The valve spring pressure also plays a role in the amount of torque required to start the engine when starting. Engines made from solid roller camshafts require a spring pressure of at least 350 psi when the valve is closed when opening more than 700 pounds per square inch. All this pressure requires much more starting torque to start the engine. BluePrint box engines use hydraulic camshafts, which require significantly lower spring pressure for proper valve control. Thus, the starter does not have to deal with extreme spring pressure for engine operation.

High compression engines

Many racing engines have a compression ratio of up to 15: 1 or higher. This high static compression puts much more pressure on the starter, which requires more torque than the original replaceable starter can produce. Almost all BluePrint engines have a compression ratio of 10.3: 1 or less. The 160 lb-ft torque that most factory starters can create is usually enough to turn the engine far enough to start it.

To decide whether to buy a costly new initiator for your BluePrint checkout, we have a few questions that you must first answer:

1) Did your old engine work well? If so, try on a new engine before buying a new one.

2) Regardless of whether you are using a factory launch or a new launch, it is very important to have good quality battery cables. Many startup problems are caused by too small, worn out or too hot battery cables due to their proximity to the heat of the exhaust gases. This is something that should always be checked before buying a new starter. $ 20 for new battery cables is much cheaper than $ 100 and for a new launch. You want 2 minimum measurements on the positive and negative battery cables. In addition, the engine should be equipped with grounding belts on the vehicle chassis to avoid difficult starting problems.

3) Do you have limited space for a great factory start your car? Space constraints often dictate the need for a mini-starter. In addition, tubular exhaust manifolds can also make it impossible to use factory starters, both due to lack of space and for immersion in a thermal starter.

Starters Ford and Chrysler are screwed directly onto the gearbox housing. Chevrolet starters are bolted to the engine block itself. These Chevy starters have a straight line on the model or in staggered order. Many customers ask us about BluePrint perforated engines. All our Chevy engines are drilled and released for models with straight and offset bolts.

Customers often ask us how to distinguish original high torque starters from standard versions. On 302 Ford Crate engines, it’s easy to see by looking at the starter itself. It may not be necessary to remove the starter to see it.

GM launchers have a ground strip that exits the main body of the starter and connects to the solenoid using a copper gasket. High torque starters will have a copper gasket about 1 inch long. Low torque standard starters will have a spacer of “or less. See
