usa dyno power figues
why o why do they come up with such radical figures,
run there cars on 92 ron fuel strap it down on a brake testing machine and hey presto 1000hp honda c90.

Does make me think, they always seem to fit loads of bolt on mods like under drive pulleys (as they like to call them) and earthing kits and get good gains, would those parts work or is it more bullshit? I mean if they worked, wouldn't they be more commonly used over here?)
over on focaljet there's loads of 500-600whp st170 engine focus,
I cant bite my lip any longer,
I have a svt with a gt35 standard head, valve springs, rods, pistons, gearbox, 525whp, this is a vid of it cellotaped down on a rolla skate, then all the goons bust there nuts.

They use different ratings for fuel ,so '92' isn't as bad as you think.
From Wikipedia but you get the idea..
Doesn't justify some of their claims though, lets not get started on their 1/4 mile times...
From Wikipedia but you get the idea..
United States: in the US octane rating is displayed in AKI (Anti-Knock Index). In the Rocky Mountain (high elevation) states, 85 AKI (90 RON) is the minimum octane, and 91 AKI (95 RON) is the maximum octane available in fuel. The reason for this is that in higher-elevation areas, a typical naturally aspirated engine draws in less air mass per cycle because of the reduced density of the atmosphere. This directly translates to less fuel and reduced absolute compression in the cylinder, therefore deterring knock. It is safe to fill a carbureted car that normally takes 87 AKI fuel at sea level with 85 AKI fuel in the mountains, but at sea level the fuel may cause damage to the engine. A disadvantage to this strategy is that most turbocharged vehicles are unable to produce full power, even when using the "premium" 91 AKI fuel. In some east coast states, up to 94 AKI (98 RON) is available. As of January, 2011, over 40 states and a total of over 2500 stations offer ethanol-based E-85 fuel with 105 AKI. Often, filling stations near US racing tracks will offer higher octane levels such as 100 AKI

not many of them are running pump fuel, most are running a high octane race fuel, the big HP mustangs have major detonation issues with the charge temp from the supercharger getting to high, so rather than sort the issue the way we would and air to air intercool the charger, instead of the crap water to air system they have from the factory, they just up the octane to sort the problem, and advance the timing or retard whichever way it goes, not sure what octane they are running but i know its well into the 100, maybe 110 octane, and as their octane is lower than ours it make me wonder what the uk octane it would be.
Do you think there's a reverse exchange rate cos we get more of their money to our pound? So in return they claim more horse power per car!
They do seem very good at talking things up

There power figures I allways think there whp is our fw power,but they do some crazy times at the track although a lot are down hill and they have nice weather heating a prepped track,but the times don't lie
It may look like that - but the slow down part of the track is elevated to aid slowing the cars. It could look like the race part of the track is downhill if the camera is on the elevated slow down part of the track.
(92 or 93 octane fuel is similar to UK 99)
E85 is not race fuel - it is 85% Ethanol 15% gasoline blend. It certainly works well with supercharged or turbo applications (higher boost and higher ignition timing makes more power).
I follow the Honda scene a little and their claims are out of this world.
Eg 500whp civic at 18psi on a gt3076... No need to go on
But I'm sure your aware jimbo they do make good power when turboed ,there was a k20 with 35x on the dyno last month and was making 550 fw @ 15psi impressive compared to the yb ,but if the yb revved as high would probably be around a similar figure
That's mental power for that boost.. Who's dyno?
Blah, blah, correction factors. Blah, blah, high comp engines that won't do anywhere near the power on regular pump fuel etc... etc...
The general rule of thumb is American whp = English bhp (atf). A story that sticks out in my head, a guy has a car, exact same spec in the states makes 270-280whp. Over here it makes 250bhp (atf)
part of the issue was with the dyno operator but it realistically made 275-280bhp (atf). Is his car slower here than if it was in the states? No, it's just that the way the correction factors in the software for stuff like ambient temp, baro is different

i'm just taking the piss jimbo I used to build the bloody things
good engine very rev happy as said good when charged

I think people get used to how it goes on cam and anything under feels gutless
