    Automotive Engine Permission

    T Please check this website. This is where I got the weight values, but I was already in the opinion that this figure may not be real because I have weighed some 1.5L engines in the past none of them exededed 90Kg. And thanks for your advise on modern turbo I shall check them out...

    Automotive Engine Permission

    Thanks for your advise, I am actually thinking of using 2.4 2AZ if the weight difference is not much with 1ZZ. I don't get the weight values properly for these engines, I also see that the 1.8 corollas that came after 2012 are powered by 2ZR engines which weighs only 97kg compared to 1ZZ which...

    Automotive Engine Permission

    Good one, Thanks for the advise. I am looking for a naturally aspirated engine because I need a stable power curve, At high revs the turbo kicks in at some point and the power curve will no longer be linear, and I am also looking for a larger displacement engine for 130hp hoping that the stress...

    Automotive Engine Permission

    I remember some one advised me to use an engine that is more than 15 years old. Legally I may not get into trouble if I go with a 15 year old engine and advertise that it has such a engine on it.

    Automotive Engine Permission

    Thanks for the detailed information, I'll get some advise from a company lawyer in my country before using the name of the engine maker. But I guess for now I can use it on the prototype and avoid mentioning that it has a specific engine on it, possibly remove the identity if any on the engine...

    You must be Don Hillberg then, you are one of the pioneers of Homebuilt helicopters. I have read allot about you in Redback aviation, it was very inspiring to see your projects and your designs. I love wooden rotorblades and enjoyed the hand drawn Gyrodyne rotor blade plans that was on their...

    Automotive Engine Permission

    Thanks for your advise, I just did some searches and found that the 1ZZ engine with stock setup cranks out 97hp at 4500 rpm and 112hp at 5500. Just a 15hp power gain with an increase in 1000rpm and the engine produces it's max torque some where around 4500 rpm. So I would do some research and...

    Thanks for your advise, Yes Thanks for the advise. I am just a bigginer with 4 stroke fuel injected engines with ECUs, My project requires 130hp peak power, I was in the initial opinion that if we revv low and try to get this power we might have a higher BMEP which stresses the piston and the...

    Automotive Engine Permission

    Yes, I want to use it for production if I did a good job on the demonstrator (Prototype). It is an undersquare engine and loves to revv low, I'm looking for 5500 peak rpm. I'm thinking of remapping the ECU and leave the engine stock.

    Automotive Engine Permission

    Thanks for your replies, I could see that Viking aero engines uses Honda engines and Aeromomentum uses Suzuki engines. Factory built Helicopters such as AK-1uses Subaru engines. And I'm wondering how could these guys obtain permission to use the names of automotive giants. I'm actually planning...

    Automotive Engine Permission

    I'm planning to use 1ZZ engine, though it is less powerful than the 2ZZ and slightly heavy it is less complicated.

    Rotor Weights

    Hi all I've built a set of wooden rotor blades with NACA0012 airfoil and I added noseweights. Since the density of wood is constant through out the blade it balances at about 40% of the chord. In order to make the blade balance chordwise at about 25% we attach nose weights. I tried having these...
