most dynos in my experience out here read whp, not at the fly... it's in europe where output is almost always at the fly from what I've seen.Quote:

We use Ron. You can get a range of gas - regular in the low 90's, then more premium is usually 95 and up.Quote:

you're not getting any higher of an octane, and the whole ethanol thing is something that isn're present everywhere in the states... only in some parts part of the year.
yeah but I believe the 100RON stuff has Ethanol in it :( So the best is actually 98RON
98 RON is the equivalent of 93 PON at US.
which is readily available in most of the us... so I'm still not getting where the whole "the US gets much worse gas then everywhere else" logic comes into playQuote:

Saxman, go look into ur laws that bushy has passed. American gas is alot less pure then aussie stuff.
Sure the dyno's read 'WHP (yo)' but the fact is, the numbers are inflated in such a way (25-30% above the hp output) it simulates flywheel HP. The reason why they are inflated? Its just how the industry has dictated itself. DO i care they are inflated? No. Should u care they are inflated? No. The only reason this point has been brung up on an Australian forum is because so many people like to compare power outputs. The simple fact is, you cannot compare power outputs from cars around the world because the measurements are all dont in different ways.Quote:

1)
Thread title: "Yo dude, my car made 500whp/304wtq".
Contents: "Yeh how cool am i. the SAE corrected numbers were 420whp, but that doesnt apply too me"
Even dynojet tried to bring in a corrected system. Correction allows comparison across different climate zones. All these factors influence power output readings taken by dynos.. Americans dont seem to really care though, they will use whatever value is higher
2)
Thread title: "Yo my car made 300whp/200wtq"
Contents: "Well it actually made 220whp but it was on a mustang dyno, and the tuner who i paid alot of money for said that his dyno reads alot lower then the dynojets."
So now we have penis envy. Suddenly your car is more powerful than it really is. Its more powerful then the dyno tells u it is...
Lastly, we come down to a single point. Consistently (we, aussies) read about stock car power outputs on american sites. These stock power outputs almost match the manufactures ratings (which are acheives on engine dynos without accessories and under the most perfect condidtions known to man (fuel, oil plugs and spark all altered to give the best HP reading). Along with this, we can directly compare the readings to what out dyno's output. Our dyno's output numbers as expected when taking into consideration basic physics and mechnical principles. These basic rules of power loss through intercia, motion and yadda yadda all back up 100% that our dyno's read the 'truest' when it comes to whp.
Please dont take offense to the above. It isnt suddenly making your car any slower, i promise. If everyone beleives a lie, does it make it a lie? No! and thats all u have to care about!
LOL, that's so true!
A lot of research that Rototest did into driveline losses revealed one major point. Very few cars came even close to their advertised flywheel HP figure as stated by the manufacturer.
I know that GMH is one of Racefuels (the ELF race fuel distributor) biggest customers.
