GRP Connecting Rods

The alloy wheels are one of the pillars of the race fraternity. They have some great advantages in an race application, but for use wider in a more conventional car application, maybe circuit races, or even your daily road car, there are some disadvantages. We are here with UD from GRP, who is a specialist in making al So, first of all, obviously, when we are talking about al Is that the case? Normally, in a big Chevrolet wheel, sometimes you see a weight saving of up to 200 grams. So, when everyt That's right, I mean, absolutely, it will be easier for the virabrequin, easier for the main networks of the block. Right? So, why do we see al Because in the world of races, when you go to an increase in power application, you need that shock absorber, which is what al It does not transfer all the impact to the rolling, already in a street race application, because of the engine's deceleration, al Okay, I want to focus on both individually. So, let's talk about the capacity of shock load. So, you are talking about increase in power here and particularly, although obviously we do not want our engines to detonate, when we are talking about very powerful engines, we are adjusting well to the limit. Therefore, al Is this is correct, but the opposite is that, as it is absorbing part of this shock, you are constantly flexing the material, which is part of the reason why you will not see the life cycle of an al So, this is really the big issue that is s The al Correct. Al T Ok, we will talk about the life in the field, but you also talked about the forces in the acceleration. So, can you talk about how t Well, And this is, again, part of the reason why you do not get the same life cycle as an al Now, t Because in a race, although we have to unbuckle the piston or change its direction as it passes from the dead point to the top, making the transition from the power course to the exhaust course at the end of the race, the engine turns off. So, how does t For example, right, And that's why we don't recommend an al So, the vacu So, when we talk about the choice of an al The weight of the component, the course of the v-brake, the engine RPM, they are all factors and also the fixer you have in the rim, they all enter a game, right? So, I realized that you didn't mention the power, w You can tell us why the power is less important than the weight of the component, RPM and course. Normally, the compression charge in a rim is not what is worn out. Again, it is the whole of the piston rim reac T Unless you enter a situation in w So, when it comes to the expectation of life of the rim, t And, obviously, it is impossible to say that a rim will last, let'say, 200 laps on the track. There are all these factors about w The best t Considering these things, we can give you an approximate now, there are some other factors with the design of the league rim. In particular, when we look at the main rims, there is a pin that locates the rim's cast iron. Now, why is t We do not see t As an al So, this is just the rate in which the al T So, t It increases as the rim heats up, but we do not recommend compensating t We do not Normally, it is better to use your rim with a standard oil stain knowing that it will get a little bigger. And if you notice a drop in the oil pressure, I would recommend using a Now, the design of these league rims also. We conventionally see that league rims are a design of Vigai. When we look at steel rims, both are Vigai or HBAM, because the Vigai design is so popular with al Ah, manufacturing, for example, also has space limitation. With the HBAM steel, the Vigai is so wide that now with great combinations of courses, the steel runs to the command axis or to other areas, and you have a problem with the rim. And even with the Vigai design and how it is, they are already wider through that's right, in al So, when it comes to manufacturing these steel rims, you only have ready-made products for use or also manufacture them as per the specific requirements of the user. We have very few t Practically everyt And what is the typical response time after you receive a request? From 2 to 3 weeks. One of the other aspects about which we often hear is that al Now, you can tell us about what really happens and what is the real problem of lengthening al You don't really see lengthening al I the material grows thermically due to expansion. The al That's what you're seeing. And you have to compensate. You will need more foil from the piston to the head with an al So, can you give us an example of how much additional foil we should be looking for? Obviously, t Normally, let'say a small block Chevrolet candle of 6 inches of length will grow to 10,000 inches at a temperature, right? So, in fact, it's not as much as most people probably recommend. I heard recommendations from around 40 to 60 thousand additional foil. T Look, Ud, thank you for giving us some information about these candle lights. If people want to know more about PRFV, how can they contact us?
