Still waiting for that and a coil pack to turn up.

Although there are a change of plans afoot with that side of things.

 

Knibby: whoops, well spotted mate V3/4 HT Lead 1


Mark: Do you live in the Manor ? Next time I pass I'll pull up on the front lawn & get it a setting 6 of the Launch Control (Clinic lol)


hhh: thank you mate. Not so sure about an R1 with a decent rider ? but I'll be honest by saying I have not come up to a bike yet that has roared off into the distance. The P1 stays with them (the last time being about a dozen in a pack) on the May Day run.
It's all good fun but racing bikes is a bit dangerous as they are all nutters and we were all only inches away from each other.
After a blast we often pull over for a chat as they want to know about the car.
Top fellas though.

 

Clive the image of P2 looks superb, definitely different and appealing to the eye.

Daz well what can i say besides hats off to you for the engine which looks pristine.

Definitely looking forward to this running and hearing it go. Keep up the good work guys.

 

Thanks Baly, hows you matey ?

 

I'm well mate, just busy with work and rebuilding engine plus trying to rennovate the new house....too much going on in all honesty but thats just life i suppose.

Glad to see your still passionate about monster scoobs after building P1, as some people usually give up on the one

Hows the company doing? we seem to be putting a lot out to tender with euro drilling lately you know? if you need me to spread the word for you and work let me know, nothings guaranteed but every little helps i suppose.

 

Jeez,,, you have a busy life too by the sounds of it.

I was reading somewhere the other day that an estimated 72% of auto projects were never seen through until the end. I had the opposite, I never knew where to end . Olly Clark finally made me see sense saying that they had reached the point I had initially asked for, and he was right.
I got a monster for the road, a monster indoors, so one for the track will be about it.

We are still quiet, just ticking at the moment.
I would welcome anything you could put our way mate. I'll see your ok.

 

Question


A single horsepower( 1 Bhp) is defined as the ability to lift 550 lbs, one foot (12") in one second.
So in order to lift 550 lbs, 12" in exactly one second you will need exactly 1 Bhp, hence the term that we all know lb / ft.

Why then do I have 562 Bhp but only 500 lb/ ft ?

What do they call the 62 missing Bhp ?? and where has it gone ??

 

Don't you mean ft-lb/s ?

 

Not sure, when reading up on things I've seen it written both ways ?

 

Torque is not a measurement which relates to time.

Power is.

Power in BHP = (Torque in Lb/Ft x RPM) / 5252

ergo

Torque in Lb/Ft = (Power in BHP x 5252) / RPM

why 5252?

Because 1 bhp = 550lb/t per second. x 60 to convert to minutes = 33000

33000 / 2 pi = 5252 (rotational force, innit)

So if you look at your graphs (provided the units are in bhp & lb/ft) they will be the same at 5252rpm.

 

Which website are you cutting-and-pasting this from?


BTW SF - I think that I might have your missing 62 lb-ft of torque

 

Ask any women Clive because they have an indepth knowledge about this very topic.

 

Pasted from a guys explanation in our P1 club.

 

 

The equation doesn't factor in resistance for friction. Energy can not be created or destroyed so has to go somewhere. In this case I'd have thought the power (energy) is lost in the form of the friction which will covert to heat. hence the difference in torque to power. It's been a while since I done physics so all that may be drivel lol.

 

Its mainly drivel

The power that we talk about is measured at the flywheel, so it already taken into account the losses due to friction in the engine, belt driven things etc. Power made in the cylinder is more than is measured at the fly, which is more than is measured at the wheels thanks to transmission losses.

Torque is a function of power and rpm as described by the equation a few post up. Which is why torqu differs from power at any given rpm, except at the constant, which happens to be 5252

 

 

nice

 

I thought it might be lol.

 

Very smart....

Do you do artwork by trade?

 

Very informative, although it may have been just as easy to say it's because yours is a 2 litre Clive. Should you have had a 2.1 or a 2.33 like you are building now, your torque would have been closer to your bhp, ain't that right Stus.

 

Ok Martyn thanks for that mate.

 

Yep

 

Never miss an opportunity to post one of your dyno graphs on someone else's thread, eh Martin.

 

That is a good result considering on 10% Martyn !! Good stuff

 

and who typed it cant spell lol

 

Now have the gearbox cradle/bolts and heater matrix hoses.

On the move again now folks.

 

sorry Stephen

 

Thanks Clive, hope you don't mind me grabbing the opportunity to post one of our graphs in your thread

 

560 lbs/ft on a 2.1. how much boost was this running martyn to achieve that

very good torque result btw
