LTA & turbocharger ruling ?

[taaouicha]

okie i dug this up from lta website

 

Superchargers or Turbochargers

 

The addition of superchargers or turbochargers to a vehicle may adversely affect the safe operation and its exhaust emission characteristics. Therefore, LTA would require the following to be submitted for evaluation:

a) Technical specifications and installation details (including pictures and drawings) of the proposed supercharger or turbocharger.

b) Certification from the vehicle manufacturer stating that the supercharger or turbocharger is suitable for the vehicle on a per make and model of the vehicle.

c) Certification or test reports from LTA/NEA recognised test laboratories to show that the turbocharger or supercharger when fitted to the vehicle on a per make and model basis complied with prevailing exhaust emission standards.

Since its kind of widely know that rally cars in Singapore, wrx/ evos etc do install such things are we bikers allowed to do the same?

 

Instead of going through the usual route of full system, pc, race cams etc modifications... im thinking why not go the path of a turbocharger? Turbo kit costs abt 5k sgd but conventional modifications work out to be almost the same

 

Bikes can be fitted with such a system that is a fact, so assuming i can find a semi competent mechanic that can install a system from a turbo kit purchased online it should work rite o.O

im wondering if any biker in Singapore actually did this before and how did the lta clearance go ?

would love to know the answers too ....

 

turbo chargers are hidden ... you could even put on the oem exhaust to it ... i guess inspection does not even check for this ...

 

but

 

do give more research to it ... as installing it will greatly effect its engine "life" ....

Definition

A turbocharger is a small radial fan pump driven by the energy of the exhaust gases of an engine. A turbocharger consists of a turbine and a compressor on a shared shaft. The turbine converts exhaust heat to rotational force, which is in turn used to drive the compressor. The compressor draws in ambient air and pumps it in to the intake manifold at increased pressure, resulting in a greater mass of air entering the cylinders on each intake stroke.

The objective of a turbocharger is the same as a supercharger; to improve the engine's volumetric efficiency by solving one of its cardinal limitations. A naturally aspirated automobile engine uses only the downward stroke of a piston to create an area of low pressure in order to draw air into the cylinder through the intake valves. Because the pressure in the atmosphere is no more than 1 atm (approximately 14.7 psi), there ultimately will be a limit to the pressure difference across the intake valves and thus the amount of airflow entering the combustion chamber. Because the turbocharger increases the pressure at the point where air is entering the cylinder, a greater mass of air (oxygen) will be forced in as the inlet manifold pressure increases. The additional air flow makes it possible to maintain the combustion chamber pressure and fuel/air load even at high engine revolution speeds, increasing the power and torque output of the engine.

Because the pressure in the cylinder must not go too high to avoid detonation and physical damage, the intake pressure must be controlled by venting excess gas. The control function is performed by a wastegate, which routes some of the exhaust flow away from the turbine. This regulates air pressure in the intake manifold.

 

Motorcycle applications

Using turbochargers to gain performance without a large gain in weight was very appealing to the Japanese factories in the 1980s. The first example of a turbocharged bike is the 1978 Kawasaki Z1R TC. It used a Rayjay ATP turbo kit to build 2.3 kg (5 lb) of boost, bringing power up from c. 90 hp (67 kW) to c. 105 hp (78 kW). However, it was only marginally faster than the standard model. A US Kawasaki importer came up with the idea of modifying the Z1-R with a turbocharging kit as a solution to the Z1-R being a low selling bike. The 112 hp (84 kW) Kawasaki GPz750 Turbo was manufactured from 1983 to 1985. This motorcycle had little in common with the normally aspirated Kawasaki GPz750. Nearly every component was altered or strengthened for this GPz 750 Turbo to handle the 20 hp (15 kW) increase in power. In 1982, Honda released the CX500T featuring a carefully developed turbo (as opposed to the Z1-R's bolt-on approach). It has a rotation speed of 200,000 rpm. The development of the CX500T was riddled with problems; due to being a V-twin engine the intake periods in the engine rotation are staggered leading to periods of high intake and long periods of no intake at all. Designing around these problems increased the price of the bike, and the performance still was not as good as the cheaper CB900( a 16 valve in-line four) During these years, Suzuki produced the XN85, a 650 cc in-line four producing 85 bhp (63 kW), and Yamaha produced the Seca Turbo. Both had carburetor fuel systems).

Since the mid 1980s, no manufactures have produced turbocharged motorcycles making these bikes a bit of an educational experience; as of 2007 no factories offer turbocharged motorcycles (although the Suzuki B-King prototype featured a supercharged Hayabusa engine).

conclusion : bike manufacturers used turbos in the past o.O

Hope to get warm welcome from you all and learn from you all as well.Last thread I posted that I was a fan of Kawasaki ZX10R but after I read a thread that posted by Ryaan that made me realized and educated me not to start with ZX10. So I opened my mind changed to ZX14 and seems that I can also afford to buy it and like it as well.

 

Well, let's start into the contents of this topic. First, which one is the better for Ninja ZX14, supercharger or turbocharger?

 

My planning project for customizing my ZX14 are:

 

Vortech V-2 supercharger

NOS (2 bottles)

Akrapovic Evolution Exhaust

K&N Air Filters

Dynojet ZZR1400 Power Commander 3 USB

Billet Adjustable Cam Chain Tensioner

Larger Injectors

Aeromotive Billet Fuel Filter (coarse)

4 coil MRE Electric/Air Shifter kit

Aeromotive Billet Fuel Pressure Regulator

BTC MOTO Quickshifter 4 Coil Kill Box

Nitrous/ CO2 shifter regulator

Carrillo Con Rod, H Beam

APE adjustable camshaft sprockets & adaptor plates

600bhp fuel pump

 

My objectives on this customizing project:

 

Able to drag less than 10sec in quater miles

Truely High Performance Drag Bike

Uniquely Customize

 

The list is what I plan to do with. So can anyone please let me know which parts are more important to custom first before fixing in the supercharger? Which parts should i change(if all above then skipped this), if not please let me know. Which supercharger would you guys recommend for me?

 

Hope all of you guys can let me know and advice me. Advices and guidances as well as helps are highly appreciates.

 

Welcome Kent! Truthfully if you are really wanting to produce a dragbike for the least amount of money you would stick to Suzuki's, either the Hayabusa or GSX-R 1000. Not nearly as many parts are made for Kawasaki's. When modded the ZX-14 as of now won't produce the power of a hayabusa nor the e.t. times of a GSX-R 1000. The quickest 64' streetbike 07' GSX-R 1000 turbo runs 7.83 @ 193 in the 1/4 mile, is street ridden and it didn't cost much to do as compared to what a ZX-14 will require. Yes that same bike ate all of the Hayabusa's also because a GSX-R 1000 weights less and will produce nearly the same whp. No one that I know of makes a competitive supercharger. We all use turbo chargers from Velocity Racing Turbo Systems or NLRSystems.com. I will quit talking about Suzuki's.

 

No offense SBN, this is a serious website for dragracers by dragracers. Psychobike.com

The issue with the ZX-14 is that stock vs stock off the showroom floor it's just as fast if not faster than the Hayabusa. Once you add in mods it won't stand a chance being that the R&D isn't there because Kawasaki doesn't sponsor the independent race teams so no one makes parts for them compared to their rival. There is currently bearing issues when you add spray, turbo or bore it out. Thus you will need to have deep pockets to keep up.

 

The blocks aren't as strong as a Hayabusa and don't have removable cylinders either. So that's a big negative. Stock cranks fail early and no one makes an aftermarket one as of now. Those are drastic differences. Even the ZX-12 had a removeable cylinder. The 14 motor dimensionally is smaller than a 12 so you can't bore it out as much as a 12. ZX-14's are having oil starvation and bearing issues when modded to produe big power. That's very limiting and requires more rebuilds.

 

The ZX-14 will take about 250- 285 whp before you have to do internal mods, the GSX-R 1000 will take 250 whp and the Hayabusa will take 300 whp before internal mods. On the upper end the ZX-14 hasn't been known to handle more then 450 whp where the Hayabusa has been able to take 700 whp reliably 600-650 being now typical. A GSX-R 1000 will take 450 whp all day with no issues there are plenty over 500 whp.

 

If you want the best performance you will do a stage 3 turbo kit with all the electronics ( stand alone or piggy back ecu, a PC won't be sufficient enough) and water injection. You will need JE low comp pistons. Rods there are three big companies Crower, Falicon, and Carrilo. I ranked them in a personal order. You will need head work done, port & polish. A drag worthy clutch, MTC, GANN or such. You won't need to bore it out or need NOS. The turbo will do all the work.

There are other companies out there, but I just touched base on the best ones that actually compete and stand behind their work. I just scraped the surface. There is alot more out there. Overally go here iB::ZX-14, research and feel free to ask me any questions. My ZX-14 knowledge is limited compared to the GSX-R 1000 or Hayabusa.

Got this while surfing some american forums about turbo chargers

things that can be deduced

 

Suzuki bikes, the engine while in stock conditions are best in handling turbo increases in wheel horsepower.

 

better turbo system cause a person to do more modifications.(stage 3 turbo kit)
