LB per BHP 5.0

[berettagt88]

What does this mean? Is it the weight I'm trying to make a '69 COPO camaro replica

 

[seanneedscar]

I'm assuming it means power to weight ratio.

5,000 pounds : 1,000 HP

2,500 pounds : 500 HP

and so on.

I don't understand then what is LB per BHP 5.0 that is the spec.

 

[seanneedscar]

I don't understand then what is LB per BHP 5.0 that is the spec.

LB (pounds) per BHP (brake horsepower) 5.0 (5 pounds)

that means, for every 1 horsepower the car has, it weighs 5 pounds

i cannot guarantee this is what is implied by those specs

if the COPO has 435hp as my research shows, that means it would weigh slightly over 2k pounds, which couldn't possibly be right for a '69 camaro

 

[jgancherjr]

Hmm, I'm not sure but I know your theory isn't correct.. You would just heave to find the power to weight ratio for the COPO Camaro or it's weight.. Not all cars have a power to weight ratio of 1 ( 1hp to 5lbs) take X1 for example which is 3 to 1 (ish) or the ford GT which is 1.56 to 5 (I believe) ... I will look on google for the COPO weight specs for you and let u know ASAP.

 

[jgancherjr]

Ok.. Www.camaros.org/COPO .. If you read down it will say the COPO Camaro was shipped with 430HP and weighed 3300lbs.. Making it a power to weight ratio of 1 to 7.674 ..

\Not all cars have a power to weight ratio of 1 ( 1hp to 5lbs) take C1 for example which is 3 to 1 (ish) or the ford GT which is 1.56 to 5 (I believe)

Were you talking to me or the OP?

I would assume such an obvious bit of info wouldn't be directed at me who clearly has an understanding of the thread.

Anyway...

my best research showed the COPO to be 500hp and 3300 lbs. which would be 1 to 6.6

in test drive 5 it says LB per BHP 5.0 and 550 hp and 550 lbs

 

[seanneedscar]

in test drive 5 it says LB per BHP 5.0 and 550 hp and 550 lbs

which would give it a curb weight of 2750 pounds

So clearly this is a 'modified' version of the COPO since its in a test drive game. which is laughable

If you are making a COPO replica, why not use REAL specs?

That's a game..

No your all good Sean! Talkin about the OP!! But I believe you found the specs for the Yenko not the COPO

How did you figure that out? It's a '69 Camaro ZL1 with aluminum block 427 and a 4-speed muncie m22 transmission. I have Netflix and I watched Muscle Car Tv series and they had a episode on the Yenko,COPO and ZL1 and they had no weight stats just tranny and final gears and estimated hp of over 500hp. I appreciate the help.

Did you go tithe website I posted earlier?

No I didn't I will now thanks.

I think the power to weight ratio in a x1 is 6.8125

 

[jgancherjr]

Well I forgot the 500 was KG and not LBS sooo to be exactly exact.. The 2010 X1 is 1557 HP and 500KG.. 500KG=1102.31 pounds.. So the power to weight ratio is 1.412hp/1Lb ... Insane...

 

[Famine]

lb/hp ratio is the vehicle weight divided by the vehicle power.

That's three bits of information. If you know two of those things, you can calculate the third. You're saying the lb/hp ratio is 5.0 and the vehicle power is 550hp, so the vehicle weight is simply 5lb/hp * 550hp = 2,750lb.

ok thanks for the formula how to calculate .

 

[Famine]

If you want to know weight to power ratio in lb/hp you need:

• Weight in lb
• Power in hp
• Divide weight by power

If you want to know weight in lb you need:

• Weight to power ratio in lb/hp
• Power in hp
• Multiply weight to power ratio by power

If you want to know power in hp you need:

• Weight to power ratio in lb/hp
• Weight in lb
• Divide weight by weight to power ratio

 

[shirakawaa]

Am I remembering correctly that the power to weight ratio in earlier GT5 versions used to be calculated literally by diving power by weight, resulting in values typically smaller than 1 ?

I calculated the x2011's power to weight ratio and it's 1.3625

 

[jgancherjr]

I calculated the x2011's power to weight ratio and it's 1.3625

Should be more? Is the 2011 500kg also?

 

[lldantell]

Every x1 is 545 kg

 

[seanneedscar]

Should be more? Is the 2011 500kg also?

1.3 is better than 1.4

The COPO Camaros horsepower were all not the same. Not all COPO camaros had the same engine.

COPO stands for
Central
Office
Production
Order

The same place you could order a Taxi or Fleet van. Or any special purpose car.

A COPO ZL-1 camaro was a corvette engine mated to a camaro chassis. It made over 550 HP, but the factory never claimed more than 435 HP or so.

They weighted around 3300 pounds, depending on options.

Hope that helps.

It's power to weight ratio is 1.20

Don't you just love that? Lately I've been determining "assumed" tire diameters for the race and pre-production models in the game (the ones you can't simply go online and look up, particularly the GT models such as the Camaro LM and GT-R Concept LM), mainly out of curiosity, and punching them into my personal tranny calculator. Sorry for going OT, I love how definitive math is though.
