"What I was asking for the system you use is if you could hold steady state at 7800rpm and average out a hundred cycles I'd be interested to see the 'mean' pressure to take out cycle to cycle variations. Is that possible the way you test? "


The tests are run like your Vbox runs.
Real world flow to the radiator, intercooler and air box. Air drag to the car... you know on the "test track".
But I can't hold load at 7800 rpm. That is passed in a microsecond.

Here is IMEP 4500 to 8000rpm (early testing with 12 psi).
If you can make out the poor screen-shot below you will see which buttons are activated.
In this case the blue HP/MEP/T /RPM button is slected then the IMEP is expanded, plus the green Cycles button, and Select Data.

The other screen shot above has Combustion selected so it runs every cycle like a movie.
That is just one frame. I would have to do a YouTube video to show you the whole run.

But yes there is a great deal of deviation cycle to cycle. Reversion problems I would guess mostly.... a good cycle pollutes the 2nd following cycle.

I'll have a look at that in more detail.

On the 'holding load' its pretty easy to do in 3rd gear or even 2nd gear as you wont have any more than 350rwkw of power and your braking system can do even on road tires -750kw (and hold -500kw lap after lap, even with fade) 3rd gear just makes it easier to pick the rpm you want. I can send you pics of a RS FD3S at a local track showing the power of the braking system ;)

Little tip for you, try it :)

hello..........
Barry did you get to the bottom of how your vendor works out 'bhp' from only an indicated power calculated method?????

Bazz any updates????

Peter what kind of dyno would you like me to put my car on?
Barry

Anything that takes into account friction power would be nice and then we can compare it to the ones on this list (which are from various dyno types). Let us know how you get on mate.

I have my own personal list of this that is about 5 times longer and has many more interesting examples covering everything you can imagine, this you just wont find anywhere else :fawk:

Doing some development work in the not too distant future which will yield some more 'first hand' quality information, may give a little teaser up here if I get excited :willy_nilly:

Barry did you test your car yet? would like to validate your results.

Dynapack is best to use, make sure TCF is set to 1.00 so I can see the raw result at the hubs.

Do a pull, log the boost too if you can.

I'll actually be able to get this data in about a week, albeit low boost (1B) and on a dynojet, but logs logs logs out the ass for three different sets of coils... FIGHT THE CDI REVOLUTION! :(

Some BIG development here, we are talking BIG! paradigm shift indeed LOL......

Got allot of set ups now around and ABOVE 300bhp per 1 bar :)

Go the ROTARY ENGINE, and these ones are doing over 800bhp engine power :) and petrol WI too :) list is gag factor in detail, bit too much to share on pubic forum though haha

Yeah, I was a the dyno a few days ago but the fucker took a shit... I got ZERO data :(

For now anyway

Shit happens man, just post a few BDC haltech E6K screen dumps and talk endlessly about it for about 50 posts in a row.... seemed to work for him and HC LOL!!! R.I.P.

This list I have is 'extensive' much bigger and detailed than ones I have sent out to selected people :suspect: really great measure to cut through all of the BS that surrounds the hype around most peoples claims and some real eye openers too ;)

How long does it take Barry? :beatdeadhorse5: :seeya:
Still waiting for power output of your engine!
I posted the above after your offer to test your engine/car, and NO updates, NO performance figures, SO how do we validate your claims/results.????

Is anyone still under the total delusion that a bridge ported engine makes more power than a street port in turbo form??????

I am sure someone somewhere...:rofl:
