who has more kilowatss 300kw ea or new xr8/turbos

[djrice]

my brother has told me his ea has just been finished tuned and is 300kw at the wheels(427stroker)

do the new xr8 or xr6 turbos have more power or are there kilowat readings from the motor or from wheels wheels looking for comparison as ea cost half the price of new xr8 and is freakisly scary to drive

[Revolver]

New fords are measusured from the flywheel. Thats where their killerwasps rating comes from. Not the wheels. The new Xr8's are 290KW so, either way, that EA has more.

[djrice]

so whats the reading from rear wheels any 1

427 stroker? In an EA? Interesting engineering......

At this time no factory FPV demonstrates 300rwkw although the FG F6 comes reasonably close in the upper half of the 200s.

300rwkw is fairly easy and cheap to achieve in a T6, less so in a BOSS but not unheard of.

Kilowatts for show, newton metres for go......how much torque does his car demonstrate?

[djrice]

power band of 1-5 street tuned by autotechnic unsure of torque but is a scary thing no engineering lol hahahaha still registered as a 6cly

Well that depends, auto & manual transmissions have different "power losses" through the driveline. I cant remember what they are for each. Its a bit of a guesstimation on what could be the Rwkw from a factory rated flywheel power figure, using the percentages of each tranny's power loss. The only way to get a "true" figure is to do a dyno run....

[djrice]

yeah thats what im after dyno compared to 427 stroker which is manual but not a tremec so will blow up eventually has ea diff housing with eb lsd internals redone.

[Mad_Aussie]

300 rwkw in an EA would make for one hell of a scary, greasy drive! What suspension is he running in it?

[djrice]

unsure suspension has redone whole driveline standard btr brakes, ac and all that removed,weight reduction done no safety features lol,best to wear a bike helmet to drive

a comparison is a moot point...

it is very low on kw against real race cars

My mates Dato is 450+hp.... so what.

A V8 Ea is illegal in every state without a hefty engineers cert, so it is nothing more than a race car................

Wasn't there a thread on here somewhere where someone had run 300rwkw (or very close, thinking 290?) in a stock FG F6?

[djrice]

yeah is illegal might put the running gear in another v8 eb or older ford depending on cash etc as car was off road for 2 years which is too long and is a headace to build a motor like this.

can call it a race car but is road registered

My mates Dato has plates on it too but it is still a purpose built racecar..


I am not belittling your brothers achievement but to compare it to a factory car @ cost vs performance is apples and oranges imho

[HLC]

Well I don't know about anyone else, but some pics would be nice. Or a dump graph. Or timeslip.

Spot on. Because when you buy a new car nowadays with similar kW to that of the OP's you're paying for the fact that it is new, with Mod-cons, proper safety features, a warranty, reliability, and the fact that said new vehicle will do those figures all day in most conditions without requiring much more maitenance than scheduled services.

[prydey]

300rwkw isn't anything special from a 427 i wouldn't have thought. there are members on here who have around that figure from a 347 stroker.

i can't believe some people think manufacturer power figures are wheel readings.

[protd]

300rwkw is a stout engine, nothing wrong with that..

[djrice]

so any 1 have put new fords on dynos for rear wheel power at all

will put up dyno sheet when i get to see it.wouldnt mind to compare it to new ford thats what im asking about nothing esle thanks

[Grechie]

impressive power i remember when i had 280rwkw in my EA it was scary as hell and obviously unreliable hehe

[djrice]

cant wait to take it for runs at the track later this year just need a stronger manual box

[302 XC]

A dyno print out will help determine its actual power

So when ya get one ,throw it up for all 2 see

Typing in a figure to an actual figure is easy
300000000 rwhp
Where should the decimal point be ???

See what i mean

So your mate has his insurance all paid up ???
No disrespect here but id hate to be him in an accident especially if still regoed as a 6cyl

[djrice]

its obviously not a daily driver.wont be driven much just track and one off cruise events running gear will eventally be moved to another car 1 day

car is stiil at autotechnics they told my bro 300kw rear wheels today.

a print will be posted then u can all have another go at the cars real power

[Iggypoppin']

To echo Mr Flappist, it's more about the torque than the power. That being said, 300rwkw in an EA well the car would want to have serious tyres and brakes, and suspension, and an engineers certificate, not just 6cyl rego and a competent driver AND a good insurance policy. Good luck to your brother, I am not doubting him, just the deepness of his pockets...

[UNR8D]

300rwkw is alot of power, especialy in an EA but.....

when it runs 300+rwkw, retains factory driveability, returns 12L/100 or less on the open road and is able to be driven from brisbane to perth with out reliability concerns ill be impressed. ;)

[xw 427]

any pics of the ea 427 setup?

Hello...... youtube...

This thread needs pics!!!! a dyno printout and a quater mile slip.. Otherwise its all just hearsay..

[geckoGT]

The answer is simple. Ford and FPV market their cars on "average" flywheel outputs, I say average as individual engines vary. I kind of thought most people would realise this as no manufacturer advertises rear wheel power.

I am sure everyone here would love to see details and pics of this beast, I know I would. To compare it with a car that can be legally driven, in day to day use, with all the creature comforts, I just do not see the point. Yes my F6 probably cost double what the build of that EA did, but it also probably does what I need for 4 times better. At least I can drive through a police check without a worry in the world or put my foot down without fearing it is going to spit its gearbox out the back. To build that EA to the same standard that my F6 is, ie correctly registered, would probably cost double what my F6 cost me and you still would not have half the comforts I have.

Like has been said, if you want to do a comparison, compare apples with apples, not apples with oranges.

Tell you what, I will organise a race, but you have to drive across city traffic to get to the track and have to drive through a road worthy inspection first as only "street legal" cars are allowed to enter. As it stands that EA is not even close to legal. By the way, do us a favor and keep it off the road, the last thing I need is an unregistered car (no it is not registered as the incorrect engine voids any registration in the event of an accident), uninsured and by the sounds of it unsafe car crashing into my car.

Sorry to be a wet blanket but track cars have their place, on the track and not on the road. If you want a road car, build one properly.

At the end of the day, my meagre F6 with its substandard 240-250 RWKW (as some have demonstrated for this model) and able to get down the 1/4 in 13.3 (which I have done), is no slouch for a factory street car.
