* Factory provided specs

Since may 2009 we saw the first announcements of a new engine brand on the WorldWideWeb.
The brand name Alpha Plus was unknown to us and we were curious where it came from.
We found out that Alpha Plus is originated in TAIWAN and we contacted Marina Huang the PR lady at Alpha Plus to get some more information.

She told us the designer and founder of Alpha Plus is the former designer of the GO engines.
Mr. Liu has a lot of knowledge about building engines.
So if you see some things that might look the same then your correct.
However the engines external and internally differ and are not made in the same factory.

One main things Alpha Plus tries to achieve as new brand name is to offer reliable and well performing engines at a low price tag.

Currently Alpha Plus offers car engines but their website also has a boat and a helicopter section for the near future.
But what about this 7 port engine we review here.
Beside the .21 (3.5 ccmm) 5 port engine there are also a 5 port .21 and a 5 port .28 engine in the program all equipped with turbo heads.

Some things that caugth or eyes when we received the engines are:

* Nicely packed and airtight sealed.
* Carburator for buggy and truggy use design with idle speed needle at correct side.
* Three air inlet venturies as standard.

We missed the user manual as these engines were one of the first shipments.
But you can download it here.

We will see and first unpack and check the engine visually.

	We received the engine  07-10-2009 from  Alpha Plus from Taiwan.
	The engine and all parts in a nice box.
	The contents of the box.
	The Flashy Alpha Plus decals included.
	The exploded view of the engine and spare parts.

I openend the box and took a first look into it.
The engine is nicely packed in a plastic airsealed bag, so no debris can enter.
The English or any other manual was not included.

In case of doubt click here for a reliable break-inn procedure and general carburator settings

Now let's go on with the hardware!!

THE ENGINE
	The engine is nicely packed in an airtight plastic bag. So no debries can enter the engine during shipping
	The engine viewed from the rear. The crank case is black anodized not for the bling factor but for reducing the engine temperature. All holes are factory covered by rubber sockets.
	The engine viewed from the front side. All holes are factory covered by rubber sockets.
	The engine viewed from the right hand side. All holes are factory covered by rubber sockets.
	The engine viewed from the left hand side. All holes are factory covered by rubber sockets.
	The carburator intake has one O-ring at the bottom of the crankcase inlet. An extra O-ring at the neck of the carburator ensures an air leak free mounting without using any extra sealing materials. The carburator can accept different colored and coded venturies. 7.0 - 8.0 - 9.0 mm come standard with this engine so you can alter the power and torque charateristics. The idle screw is at the correct side of the carburator for easy buggy and truggy usage.
	The rear cover has no special treatments and is airthight by the use of one O-ring. Do not forgrt to put the piston in the highest postion when you remove the rear cover!
	The seperate head button is ready for accepting TURBO plugs. There is no glowplug with the engine how ever Alpha Plus has them available in the program. I case you cant lay your hand on the original ones you can use OS MAX P3 and P4 plugs too. An optional head button for STANDARD plugs is available too. The head button as it came on the engine with 2 x cupper head shim washers. The extra head shim washer is not displayed in this picture.
	The rear cover removed and the first look at the internals. Do not forget to put the piston in the highest postion when you remove the rear cover! Everything nicely oiled from the factory.
	This engine is equipped with an ABC engine piston liner set.. The (B)ronze liner is a 5 port design with two extra bypass ports in combination with the (A)luminium piston. The brass liner has a (C)hromed layer that is lapped and rectified. Lapping is making 45 degrees angles scratches on the chrome surface that will enhance lubrification and sealing. A small groove assures a correct placing in the cranckcase and prevents rotation of the liner. The head is fixed with a 4 bolt pattern using hexagon screws using a 2.5 mm hexagon tool.
	The left hand side of the liner. Clearly visible the tear drop cut outs. The two extra ports visible.
	The exhaust port with some larger cut outs in the top corner.
	The right hand side of the liner. Clearly visible the tear drop cut outs. The two extra ports visible.
	The inlet port. It has a arrow cut at the bottom.
	The aluminum piston with asymetric bottom skirt. Two oil grooves in the top of the piston. Top surface is flat no extra domes or whatever. The connection rod is knife shaped and has one oil hole for lubricating the cranckpin. One hole of the large +2 bypass ports clearly visible.
	Lightend by many holes the head is light but has enough cooling charateristics. Alpha Plus brand and type logo are laser edged in the top of the cooling head.
	The 14 mm cranck shaft has a small TURBO cut out and the leading edge of the counterweigth is made in a cutting flow design. No extra counterweight or balance inserts. The carburator entry is square and there are no putties used to flow the cranckshaft. No special treatments of the crank pin.
	The two piece carburator neck clamp. No small O-rings to seal them.
	The extra webbing and the heating ribs at the bottom of the engines in combination with the black anodizing are there to lower the working temperature of the engine.
	All the parts of the .21 7- port engine.

THE CARBURATOR
	The carburator is a 2 needle composite design with a metal throat.
	The idle screw is fitted at the correct side for buggy and truggy cars.
	It accepts venturi inserts to change the general air intake from 6 to 9 mm. Venturies with 12,75 to 13 mm diameter can be used.
	It accepts venturi inserts to change the general air intake from 7 to 9 mm.  This engine comes with a all 3 color coded venturies available 7.0 - 8.0 - 9.0 mm insert as standard. Venturi measurements: Outerdiamter 12,75 mm - 13 mm

	The engine at first sigth is nicely machined and no debries or metal parts from the production process were found. Also the neatly looking and machined composite carburator has the idle screw at the correct side for use in truggy and buggy cars. Also the standard three venturies are a nice feature.

* The real engine performance and fuel economy can not be judged by looking at it. 

What we think of it?
