dynos are great for tuning a/f mixtures and thats about it.
i have seen cars make 500hp on a dyno and people think shit that must be quick but if it makes 500hp at 6000 rpm its not very usefull.
dyno figures dont mean a thing in my eyes cos they dont always mean quick times.
That is so well put,I'm all in for racing dyno's and then talking up how fast there car SHOULD BE at the track.

Mate without dyno's what would you be doing to get relevant figures... racing up and down the streets of lehkemba I supose????? with some one chasing it with an analyser????? hmmm now I would like to see that
I'd be doing what I've done in the past - Taking it to the strip.
Those figures are much more relevent than any dyno figures.
It's amazing that someone who has spent hours upon hours, whoring their car up on a dyno, refuses to give the car a few passes down the strip on the basis of not wanting to "thrash" their car... Mate, just wrap it up in cotton wool and leave it in the garage.

Peekay has given up his car as a test mule in the Hondata development process for a long time. He has been without his car in some cases for many weeks if not months at a time. We will all benefit from the sacrifices he has made and I don't see any utility in pressuring him to do something he has already said he is not going to do. His explanation for being involved in the process is more than reasonable. He is looking for improved driveability - not some stupid piece of paper that says what the car can do over 400 metres.

Ahyes, instead we have a stupid piece of paper that says with these mods you make this much power. Good on you.
Time slips are stupid pieces of paper now are they?
Here I was thinking this forum was for enthusiasts. Silly me.

You can be a car enthustiast without giving a hoot about 1/4 mile times or dyno graphs. I, for one, prefer to focus on how balanced a car is and how it handles rather than 1/4 mile or dyno graphs. Any idiot can put their foot down and drive a car in a straight line.
The dyno readings Peekay has are from the development process. He has not gone into the process chasing a number on the dyno. And yes, they are both just stupid pieces of paper as they don't tell you with any certainty how the car drives in the real world.
Disagree with you Yfin, the quarter mile slip is a much better yardstick for power, and the drag strip is the real world is it not?
What you will find that many of the others are already finding out or have found out is that many of these powerful dyno'ed cars cant get anything like a good time on the quarter mile, and it shows that most often is the case, that they really dont have the power they claim.
And no, not just any idiot can put their foot down and drive fast, there is skill in drag racing as there is in circuit racing.

Yeah for sure, 1/4 is better than a dyno chart. But I don't see the 1/4 as meaning much in the real world because of the speeds involved (well over 100kph). And yes you are right there is a skill to drag racing.
But some people seem to be blinded by 1/4 mile times. That is all they want to know. Why don't people prefer to look at 0-100, 0-60 and overtaking times. More useful to me.
1/4 mile = a number of variables involved (driver & conditions)
I think I'd have more to gain with my car down the quarter by handing it to an experienced driver.
dyno = a number of variables (calibration & conditions)
The real value is in tuning the car, power at the wheels is good for a rough idea but is hard to compare across dynos as most know.
I'd also be interested in 0-100km/h figures but, even more so, in gear rolling acceleration tests... say 20-100km/g and 80-120km/h tested back to back with a standard euro on the same day. No real thrashing of the car would be required and you could gauge an improvement more easily by eliminating a lot of variables.
