CVTs are not allowed in F1. Therefore, I think you can be reasonably sure that no team on the grid is using one.

If you have to ask on a forum like this how to design an engine, you are probably not going to be able to carry it off.

Judging by your impressive degree results you must be a very bright person....

What a great thread...

Off the top of my head and without really thinking:

Ford Kent X-Flow

Cosworth DFV

Renualt 1.5V6 Turbo (F1 engine)... For starting a trend

Am I missing something here?

You say you are going to employ weights at a variable PCD to add an adjustable centrifugal force to the wheel?

How is this possibly going to aid traction?

If...

Thanks that was very good.

I was aware that tempreture and pressure both contribute to the shaft work achieved in the turbo, but I wasn't so sure in what quantities. Thanks you've put it into more...

This is the part I had a problem with. I think you have made a good argument and on the hole we agree with each other.

yeah sorry, perhaps that was a little harsh...

Im not saying that if a turbo was fitted to the exhuast but was not fitted to the inlet side, there would be no power loss. (obviously there would be...

Interesting, that certainly gives more wieght to Holeshot's claims.

984kW = 1323HP

Very impressive.

Well thanks for your help anyway.

fpv gtho is right and lukehow is wrong on this one....

The turbine in a turbo is simply an expansion engine which works of the differential of gas pressure in...

I had a great day at the Auto sport show back in Jan. Had the chance to chat with someone from Holeshot Racing (the creators of the Hyabusa turbo engines in the GTR), although I'm not sure who...

Hi there, question for lukehow:

I am very interested to hear about this new turbo you say you have seen. Is it like a conventional turbo, but driven via a belt by the engine too? If it is I would...

Not sure if this is true with ethanol, but it might be interesting for some of you.
Petrol is burned in the engine at a ratio of around 13-14:1 meaning that fourteen times more air is needed than...

I've only ever been able to find out any real information about the Saab engine.... Although I suspected a few others had tried variable compression ratios, I don't know any detailed designs. Sorry

Hi guys,

Interesting discussion. Can I just point out that the reason for DOHC is not solely an issue a lack of space on a single cam shaft where four valves per cylinder are being used. As many...

I was only pointing out that after the combustion stroke the pressure in the cylinder is higher than it was immediately after the induction stroke. If it wasn't true, no engine would run would it?
...

May I just point out that turbos can be simply converted into miniature gas turbines by fabricating a combustion chamber between the compressor exit and the turbine intake. Some model aero plane...

Your not loosing that thrust force; there is a reaction force that must be equal apposing it! The gear is not flying through the gearbox wall is it? There will obviously be resistance added here but...

Being rude is not very proffesional is it? I have indeed spent along time building engines and do understand their workings. I have also had some amount of formal engineering training including...

Can I just say I am impressed by the 24,000rpm Honda engine! However, I don't think it was a three litre V10 was it? Like you said, it's easier for smaller engines.

I will have one more attempt at...

Yes thrust is a problem with helical gears, there’s no denying that. Does anyone have experience of ways of reducing the effect? Gear pears with apposing helix angles perhaps?

As for torque...

Hate to disagree with you again. I have always believed that helical cut gears can withstand more torque as there are more teeth in contact with each other at any one time. This is because they are...

I am in agreement with you on the up hill struggle faced by N/A engines. It was probably not the best comparison I could have used. I was merely attempting to illustrate to people who may not know...

What I am suggesting is that the turbine is in itself an expansion engine. The gas entering it is at a higher pressure and density than that leaving it (it is expanding). Because the gasses are...

I hope people fully understand what I am saying here. I have tried to keep my explanation as short as I could. If any one has any specific questions on what I have said then please e-mail me.

May...

Recently when browsing through this technical forum I have noticed the topics of supercharging, turbo charging and the problems posed by “lag” being discussed.

I recall the question being raised,...
