Sorry cant get it any clearer!

 

thats very nice...

 

Sweet

 

lots of power

 

What does 'corrected power' mean ?

 

corrected for standard atmopheric pressure i think

 

Yeah, its to do with barrometric(sp) pressure, thats the 2nd line in from the left on the printout, peak power was 587bhp before being corrected.

Harvey did explain it but, it was abit over my head!

 

SAE -- The SAE standard applied is a modified version of the SAE J1349 standard of June 1990. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque. Friction torque can be determined by measurements on special motoring dynamometers (which is only practical in research environments) or can be estimated. When estimates must be used, the SAE standard uses a default Mechanical Efficiency (ME) value of 85%. This is approximately correct at peak torque but not at other engine operating speeds. Some dynamometer systems use the SAE correction factor for atmospheric conditions but do not take mechanical efficiency into consideration at all (i.e. they assume a ME of 100%). SuperFlow uses a more sophisticated algorithm for calculating friction torque, based on a summary of thousands of friction power tests performed by the automotive industry. This proprietary algorithm estimates friction torque as a function of piston speed and engine displacement.
The "SAE corrected" power numbers indicated by your SuperFlow system are thus more accurate estimates of engine power output under reference conditions than what other systems using no ME correction or using a fixed ME of 85% will provide.

 

Good power band. Peak power where you want it with a strong even spread of consistant torque. Should be a very fast car.

 

OK, that's what I thought. I guess they use a correction factor to compare apples to apples, but IMHO, its kind of hokey since it is very rare that you'll drive in 'standard' conditions

Nice flat torque curve, looks pretty stout

 

i see what you mean,, but everything has gotta have a standard,, unless the numbers mean nothing

 

I try to compare HP at the wheels for direct comparisons.

Its true that temp and humidity will change the outcome, but if all the cars are tested in similar conditions, you'll get a pretty good idea where they stand vs each other and 1 or 2 HP difference is hardly enough to give one 'bragging rights' over another.

 

nice work

 

wtf?

 

Matt,
Even rolling roads correct the power figures to the above SAE, so same difference .

Adus,
Typical know nothing Skyline owner .

 

Awesome AND he has a proper gearbox. This should be a VERY VERY VERY fast car

Pls tell me you are gonna do TOTB

 

Hi porkie still got a couple of things left to do to it(gonna get it checked over at brunters by ahmed when the engines in the car) TOTB is pretty tempting especially the handling course but im gonna go out and enjoy the car first

 

Jon - Didn't you buy Martins old R+D Dogbox out of Car 57? Thought there torque rating wasn't that good As you have shitloads i'll cross my fingers for you

 

I'll be interested to hear if it feels that powerfull when its in the car!
Nice graphs though

 

now without trying to take anything away from this , so please dont take it the wrong way , fantanstic power and torque figures but the engine starts to lose torque at what 5700rpm ?? surely once the engine starts to drop peak torque its time for a gear shift ? hence you will only have a power band of 3000 - 5700 rpm ??


im sure it will feel alot differant than it looks on the graph and especially seeing as you have a decent gearbox to carry it off just looks a little strange to me , like it would run out of the initial "get up and go" you will have early on. or did you ask for it to be like that for a reason ?


cheers

mark

 

what will it make in the car at the wheels?
any ideas?

 

Milko Pete/Jon, contrast adjusted for easier reading:

 

Mark,
You obviously have never driven a "500" engine, as mine only made peak torque at 5k (422lb ft) and peak power at 7k (515bhp) and wanted to rev for England. If it wasn't near 8k, it wasn't happy . The torque at 7k is still MORE than mine made at it's peak .

 

Jon ,
Next time you come over to mine ,,I WANT A RIDE ,,lol,, Good figures mate

 

whouldnt mind ago as well john, hope you dont brake the box o and be carefull with the gear changes ( you know what i mean). Going to central day if so see you there and are you going to have a go

 

Not sure mark but i thought all low comp engines tail off the higher the revs

Paul no probs m8

Hi dunc it wont run at the pod because im gonna get the fuel system uprated first then get it checked over in car at brunters by ahmed
The car should be there though so come and have a look

 

What place does corrected temp and barometric pressure have with comparing turbocharged engines?

 

wow, very good mate

 

guilty as charged

 

mike ,
you 'obviously' know very little , and just for you is this before i start


i will just refer you to a certain Mr Wiles, i do seam to remember a certain RS500 having a "500" engine. please stop me if im wrong

in fact i drove that particular version of the SCS "500" engine more than on one occassion , in fact , just for the record , i actually rebuilt it after its unfortunate failure. So after all that , i still stand by my statement , having prior experiance and again i thank you
