here you go again assuming that every BOSS290s leave the floor with exactly 290kw.. news budy they don't. production tolerences ever heard of them????


as far as bretts car, you know as well i do that dynos can be fudged to produce just about any result you want it to. you spent days leading up to it going on about power losses and asking people guess, then you come out and "well %30 is 124rwkw," supries supries what do we get 124rwkw, dynos can be made to poduce numbers, any numbers regardless of actual power


LOL , woooooooooooooooooo now thats not true

bretts car has never been on my dyno prier to the test

i made a educated guess thats all

and as far as fudging dyno figures ur wrong there

i explain to all my customers what the X factor is and what the I factor is

and i have never made a change to a dyno result by cheating

Ok i give up seems ur set in ur own ways

cheers have fun

LOL no don't close this thread

its interesting to read , just remember it's a open forum

ONCE again i will put anyone body's car on my dyno as long as its standard and i know the factories horse power figures


Tickford question ?? have u ever run a BA falcon on any chassis dyno ?

if yes , what has the horse power figure been at the back wheels ?

and

if NO , can u do me a favor and phone several workshops with chassis dynos and ask what brand the dyno s are also in ur area and ask them what has there dyno figures been for the ford BA falcon that hey have run on there dyno's from there experience ??

and secondly what tolerances do u think ford is working with when they quote 290kwatts at the crankshaft ?

eg 290 plus or minus 10%

290 plus or minus 5%

290 minus 5%

290 minus 10%

290 plus 5%

290 plus 10%

cause i certainly wouldn't be a happy guy if my GT was well bellow what ford quote there horse power rating on the engine

cheers

didn't someone do a test between 3 or 4 gen3 commodore ss's, and the difference between the rear wheel kw from least to most was around 18kw?
so yeah, you might end up with a dud motor.

are the ba 290's hand-assembled?

Shame on you!
I see arguments that make sense on both sides of the fence, so I'm confused as all hell.
So I think I'll just completely ignore driveline losses and 'at the flywheel' power figures.

'So, Jared, how much power does your car make at the engine?'
'What engine.'

not the tolerences i was talking about.

i mean not every single piston is exactly same size not every bore has exectly the same honing, not every intake manifold is exactly the same shape, not every manifold lines up the the ports in the same way.
not ever port is exactly the same shape.

all of this leads to not every engine having the same power.

no i can't remember numbers off the top off my head so i wont qoute them. un like you who love to say things then a few days later when you realise how stupid it was come back and make a full page excuse as to why you said it.

and no i'm not going to call my tunner tomorrow and bug him about numbers for stock cars, as both he and i have more important thing to worry about.
after all you going to stick to your % s**t and i'm going to stick my % losses are s**t. so whats it matter anyway.

i can believe how stupid you could be as to think every engine come off the line exactly the same HAHAHHAHAHAHAHAH what a joke

hahahaha


maybe u should get ur facts right before u make acusations

and as far as the ford BA GT the motors are blueprinted to a higher standard than what u seem to know about

u make me laugh

maybe we should close this thread

and lets face it u would be shocked to learn , i have facts no fiction here

so will u get ur facts right

and to accuse me of rigging the dyno figures u way of base here in ur last posting

but then again who am i , only been in the industry as long as u have lived on this planet


what a joke

u failed to answer any of my question and its amazing all the negative in ur voice

and on this note i will not enter any debate with u nor any thread u post since it seems ur MR Correct and everyone else is wrong

cheers and have a good one mate

hahahahahahahahaha what a great laugh this has been

Oh! :lol:

the more the power the engine produce, the lesser the % lost. power to weight ratio has changed compared to factory specs.

Tickford again u said im assuming the kwatts of a ba_gt i'm merely quoting from a known figure which i would have to say ford is a reputable company and wouldn't over quote nor under quote there horse power figures. so in this case we have a baseline to work with and make a calculation of some sort

The GTHO-3 had a power output of 300hp claimed ford, and the EB/L GTs had a claimed 200kw (246hp)
so why could the HO pull a 13.7 1/4 , while the later models with 20 years more technology still barely make it under 20 sec's
Don't rely on claimed figures too much as ford did tell some s**t in both cases
the HO actually had 300 RWHP ,up to 306kw has been seen on original engines without mods

XY = 1400 and something kilograms

BA = 1750 and something kilograms

work it out now

cheers

Motor Magazine ran a BA GT on C&V's Dyno Dynamics dyno, and it pulled 241rwkw.

As for working out kw figures on percentages, someone else pointed out the percentages change depending on if you convert rwkw to fwkw or vise-versa.

Say a car has 100rwkw, add 30%, and it becomes 130fwkw.

To convert back to RwKw, you take 30% off the flywheel power figure (130kw), which means this same car now has 91rwkw....

hi

not be a smart _ass like someone quoted me and rigging figures have a read of this thread http://www.fordmods.com/forums/viewtopic.php?t=19941


" ran a BA GT on C&V's Dyno Dynamics dyno, and it pulled 241rwkw."
this dyno figure to me ( my opinion ) seems to be to high for a stock standard BA GT that is rated at 290 flywheel kilowatts from Ford Motor Company

I havent bothered to run my BA_GTp on my dyno cause i know what the reading in rear wheel kilowatts will be and i just cruise around with mine but just for arguement sake i will this week and again i will pridict (guess the rear wheel kilowatts cause i'm assuming from the factory it has 290 flywheel kilowatts

eg.

290 fwkw times 30% = 87kwatts

290 minus 87 = 203 kwatts at the raer wheels there abouts plus or minus 5%

lets see hopw i go on this one and no i will not rig the dyno figures


"Say a car has 100rwkw, add 30%, and it becomes 130fwkw.

To convert back to RwKw, you take 30% off the flywheel power figure (130kw), which means this same car now has 91rwkw.."

interesting piont i will comment just wanna see what other people have to say and its no trick LOL

cheers
