The difficulty in squeezing horsepower from this engine has set us up to use
Different solutions from the usual ones.
The classic solutions, higher boost pressure and revisiting are not enough
of the software part, we also had to work on the air flow, replacing
the turbine and a new additional air inlet on the filter box.
Absolutely without losing anything at low revs.
We also had to adapt the carburation by replacing the injectors
as his originals were not suitable to withstand the required increases in power
from the modification.
By doing so we have obtained satisfactory results, in fact I would like to say more than satisfactory.

Kslh Catalyst Probe Lambda

This product is NOT HOMOLOGATED to be driven on roads open to traffic. It is designed exclusively to be used where current laws allow so. Autofficina Bonalume is therefore not liable for any personal injuries or material damages caused by or created through the improper use of the product.
Before you start reading the technical specifications, we inform you that we do in any event advise you not to remove the catalyser for any reason whatsoever.
The new version of the ksl product is now available. This product does not replace the previous product but actually amplifies the range. The difference between the two products lies in the operating temperature that they are able to withstand. This new model called HKSL can be installed even in vehicles with very short exhausts or manifolds such as the following: PORSCHE-FERRARI-LOTUS-etc. In these vehicles the Lambda probes are very near the engine, therefore the exhaust gas is much hotter and much faster compared to a vehicle with long exhaust or manifold, or at least compared to a vehicle with engine at the front and exhaust that runs right along the vehicle before is reaches the outlet. This is because, in such configuration, the Lambda probes are much further away from the engine compared to the versions just mentioned.

Then there are other cases such as vehicles with aspirated or turbo engines, which either due to an exasperated preparation or due to a “weak” fuel mix, have the same conditions of high temperature or high speed of the exhaust gas. Such condition is unbearable for the Lambda probes too (failures in Lambda probes are indeed very often caused by high temperatures) and so we have re-designed and produced another and new model of the ksl product. The new HKSL product is able to withstand temperatures of around 1150 degrees. The high cost of the materials used and the processing times, which are tens times those of the previous version, have a negative effect on the end price. The new HKSL product does NOT REPLACE THE PREVIOUS KSL PRODUCT.

Regulator Pressure Turbocharger

Regulator-Pressure-Turbo

Unlike the previous versions we created, this system integrates a new micrometric pressure control system, which allows you to adjust and manage the pressure with intervals of hundredths of a bar to obtain and control minimum increases in pressure, power and torque, without the control unit entering recovery status.
It also proves useful when reprogramming the control unit where you are unable to obtain the attempted pressure.
Adjustments are made using a special little turning hand, and in steps of just a few degrees apart, to increase or decrease by just a few hundredths (2 to be precise).
This mechanical feature allows you to move forward or backward always in the same identical position without losing the adjustments made.
As in all our overboost systems, adjustments are made without releasing air externally.
A preloaded spring system with different working sections of the pressure allows continuous and precise adjustment and modulation, keeping the set value constant, applying a slight response delay, which will allow you to obtain also a small pressure peak different from the constant pressure set. This favours a higher torque.

Power Pop Smart

Power Pop Smart

Differently from all other breather valves on the market, which have many problems for what concerns the stability of idling and even more problems in the suction regulation and therefore causing a wrong working, we have produced and patented a breather pipe valve totally free from those problems. Our new Power Pop can be installed on any car with turbo petrol motor without any of the above-mentioned problems. The working is guaranteed also in presence of ignition/injection systems with airflow rate reading through debimeter or hot wire. The valves sold until now from most producers use a suction regulator that evaluates the airflow rate in order to stop the opening of the valve by idling and solve in this way the idling problem. This solution lets the valve open in a limited way while releasing the gas pedal and therefore alters the good working of the exhaust. With our new Power Pop this difficult and inappropriate regulation has been totally removed, therefore there is no problem at all. Guarantee of over breathing and no noise. Patent Nr. 01314079

Air Suction Manifolds

Air Suction Manifolds

Air Suction Manifolds are easy to install in every kind of filter box or wherever more airflow is required.Example: a motor with four cylinders and 2000 cc displacement has a unitary displacement of 500 cc. Then the filter box should contain 500×19=9500 cc, that is 9.5 litres. Measure the capacity of your box and you will see that you will never have the flow needed. The manifold can in no way increase the volumetric capacity of the box, but it enables it not to depress when the motor reaches the peak of suction, that is to say in the peak of torque, by supplying a supplementary suction inlet. Now someone could think that it would be sufficient to make a hole in the box without spending money on manifolds. This could be theoretically done, but a hole of 50 millimetres would react, because of the produced turbulences, like a hole of 20 millimetres that sucks air in a chaotic and whirling way worsening and not improving the motor breathing. The manifolds are available in three standard measures: Short: H 3.3 cm, hole in the box side 40mm Medium: H 6.8 cm, hole in the box side 40mm Long: H 11.2 cm, hole in the box side 40mm They could also be built according to customers’ needs.

Waste Gate Racing

Many people think it is sufficient to stretch the spring of the waste gate to easily obtain horsepower. But very few know that stretching the spring (by shortening the rod) one obtains not only more power but also a dangerous reduction of the opening door, as the stroke of the waste gate is shorter. When the exhausting door gets less open, it does not release the gas at the best and automatically increases its pressure and temperature causing those fatal cracks in the turbine and the dangerous increase of the exhaust backpressure. To face this problem it is sufficient to replace the Waste Gate with one more appropriate to the needs of the turbine. Our Waste Gates are completely built with ergal and are hard anodised and therefore can resist at high pressure and temperatures, besides they have no kind of diaphragm but a piston that has a stroke that is double than in a normal waste gate. To order it, it is sufficient to state the pressure you want to obtain and the car model. In some cases our Waste Gates are equipped with bolt and tie rods, while in other cases the installation needs the original bolt. In this case it is sufficient to detach the Waste Gate from its bolt, which will be later used as support to our Waste Gate.

Unlike the pneumatic control valve, this model represents the evolution and about the sound(I puff air) or to the operating speed.
The air is always the same as the previous model.
The major change is the drive system.
Whereas before in our valve and all valves on the market was the tire with its delays now is electric so zero delay.
Resulting in increased amounts from download and consequently a high sonority.
In addition the following opening and closing exactly driving style without imposing undue and situations distressing situation of late.
To provide complete information, you should be aware that when we are speaking of electric or pneumatic valves, we always mean valves with the same identical functions.
The differences are merely in the opening command
In the electric valve, there is a magnet that is energised by the flow of current, which pulls a plunger toward it, which in turn opens an orifice where the air to be vented passes. The discharge may be open (valve with hissing) or closed with recirculation (silent valve).   In the pneumatic valve, the opening and closing command is given by a small tube that has to take pressure and vacuum to fill or empty a chamber with either a diaphragm or a piston inside it. In the pressure phase, the force of the same applied on the face of the piston or diaphragm, keeps it pressed down, closing the venting orifice, while in the vacuum phase, on the face of the piston or the diaphragm, a negative force will be applied that pulls upwards, thus freeing the orifice below and venting the air. Having said this, it is clear that the electrical execution speed is way higher than that of air.
