Too much hp-talk, let's talk real life numbers!
Horsepower-ratings have been so hyped on this board nowadays.
And while most people claim they want a broad torque-curve, they only talk about peak numbers..
At least on the ricer boards they admit it (did I say that!? )
What is important (except for fame and glory on this forum) is real life performance numbers. Like 1/4 mile trap speed and 100-200 km/h.
So please post your numbers! Let's see how fast your car really is.
This is especially interesting for us in Europe since our "dynos" mysteriously tend to show a lot less hp than those in US.
Unfortunatly I suspect that there's more people with dyno sheets than performance numbers..
I'll be the first one out:
191 km/h (118 mph) 1/4 mile trap speed
100-200 km/h in 8,9 sec.
I'm sure this post will upset some people so please post away while I seek cover

With a G-Tech RR.
I realise not everyone have access to one, but if you don't have access to any other accelerometer you could use the rpm-interval if you have datalogging with timestamp.

This is a very good method to test the performance. However, tire size, vehicle weight, outside temps all play a role and must be taken into consideration for a valid comparison.

1/4 trap- 98 mph smoking the tires at the line, waiting for green, and thinking "the tires are gonna hook up some time". tomorrow is street legal drags at my local race track, so i should have better numbers by then. as far as 100-200 times, i'll have that tonight after i find an open road.

I would think the only way to really compare cars is to do a heads up comparison. Even then you would have to take the driver variable into consideration. Its fun for all of us to read all these numbers, but at the end of the day that's all they are is numbers. Just go out and drive your car, if you're not happy with the performance spend more money. If you're happy after a drive, put the car in the garage (under the cover), and drink a few of these

The dyno has correction factors... Of course enjoying the car is #1. Road test with time only involves many other variables, oh yes, gearing is to be added to the equation.

Dyno numbers would have the similar variables, would they not? outside temps, intake fan, tire size(?), different types of dyno

ditto man.....way too many people are hooked up with dyno numbers here....its all about enjoying the performance we already have under our right foot!!!!!! ****....even in stock form our cars are fast

Do you start at a steady 100 kph or do you accelearte through 100 from a lower speed starting point? This will make a sizable difference.

As said, many variables affects the measures speed but IMHO they account to the numbers a lot less than different dyno readings. I've earlier seen numbers here on rennlist from credible persons where one states 8,8 sec 100-200 kph with 450 rwhp dynojet...
But you don't see anyone post all those different variables when posting 1/4 mile time slips so I don't think a posted 100-200 kph time need to be any different.
As I suspected this thread is pretty quiet. Too bad...but I suppose more people are after big HP numbers for bragging rights than for actually making the car faster.
