Engine Build and Turbo Motor Cycle Modification Style

With the motor sorted out, it was time to match a new turbo kit with the performance capability of the XR-1.7. Cue in Boost Logic’s SC 61 turbo kit. Boost Logic is new to the Evolution world, but have a big reputation for making gobs of power in the Supra market. Their SC 61 turbo kit shows right away the proof in the power making pudding, especially with features that compare to what the more expensive kits have for less money. Features include:

• Ceramic Heat Coated SS304 Tubular Manifold w/ true merge collector(1/2" Thick flanges)
• Tial 44mm Wastegate
• SS304 Dump Tube
• PTE SC50 T04E DBB Turbo w/ vband outlet
• Boost Logic Water Line Kit(assembled with Aeroquip pushlock fittings)
• 3" SS304 Vband Downpipe
• 3" SS304 Vband Midpipe w/ flex joint(Bolts to stock catalytic converter)
• 3" Aluminum Intake Pipe 3" K&N Filter
• 2.5" Mandrel Bent Aluminum Intercooler Pipe
• 3 Ply Silicone Hoses and SS Hose Clamps
• Boost Logic Oil Feed and Return Kit(Assembled with high quality SS line and AN fittings)
• All nuts and bolts needed for installation
• 10" High Flow Fan

Installation of the entire setup was complex and will require professional help. With our lack of wrenching skills we opted to go with pros to get everything installed correctly. Atlantic Motorsports was the shop we went with to get the final installation done. Being a MIVEC conversion, we had to grab a spare Evolution 9 main harness (engine harness) in order to get it all plugged up with our AEM EMS (we had to purchase a new unit to control MIVEC). The conversion isn’t rocket science but does require a large portion of time to make sure all the details are taken care of.

With the basic installation out of the way, the proper motor break-in procedure needed to be performed: 2 heat cycles, then an oil change, then a low boost break-in, 200 miles of driving, and finally another oil change. Atlantic Motorsports then put their focus on tuning the beast. With a few clicks on the laptop and a ton of dyno pulls, the car was ready for action. Final Power Output: 498 whp & 399.3 ft-lb @ 23psi.

HOW TO WORK AS Noken AS NEXT:

1. If point A touches the trigger, the valve began to open up and will be full after a head protrusion (point B).
2. After passing through the peak, the valve back down and closed the meeting after point C.
3. From A to C and then rising and then back to B is called the duration Noken as.
4. Highest Lift determine bulge Max.
5. The form of the surface bulge profile and determine the acceleration of valve closure by the form of the surface profile prominent.

Lift MAX
How to determine the Max Lift the motor racing:
In theory for standard motor, Lift Max is 23% of the diameter in the valve. Then, for the motor racing circuit is not very long, Max Lift approximately 29% - 31% of the diameter in the valve. To race with the long circuit, Max Lift can be studied up to 35% of the diameter of the valve.

Duration
How to calculate the duration of several ways:
1. Duration is calculated after the 1.27 mm valve lift on the valve setting of 0 (zerro).
2. Duration is calculated at the time the valve starts to open the valve on the 0.10 mm.

To facilitate the creation, we will use the second way. Before we want to determine the length of numbers, we must first know how LC (lobe center) on Noken as we will modify.

To know the LC, we must install Noken as the engine and measure with a protractor mounted on the crutch as the left / magnet.

For example:
LC TO JUPITER Z: 103
We want the duration of 310 degrees.
How many degrees in the open and close in degrees?

To Search for a calculation in close:
310 - 180 - 52 = 78

That means that for LC 103 IF WE want duration duration is 301 FIGURES:
IN OPEN BEFORE 52 tma
CLOSE IN 78 AFTER TMB

For the duration of motor racing is ideally 29 - 33.
Max lift for the duration of motor racing is ideally:
7.5 mm - 8.3 mm

Benefits of using a high lift and duration of:
- Power engine to be very large
- Engine is very good on lap top

Loss using a high lift and duration of:
- On lap down less good
- Per the valve does not become a lasting
- Floating valve / float valve when the pear is not strong
- Holes the valve on the piston must be in

HOW hone CAM
- The Base Circle digrinda approximately 18 to meet the desired lift
- Then followed by hone the ram to determine the duration
- Hone the flank lift to determine O / L and form the profile
- Try Kem in the hone with a flat and smooth to ensure that the rocker arm and reducing fixed durable floating.
