Rolling road (BHP figures)
Discussion
I'm quite interested in seeing what my BHP figure is.
However, the local place has somewhat put me off.
The cars I've seen have this done, have basically had the nuts revved out of them, twice.
Is this the only way of doing it ?
There seems to be a lot of large warning signs, quoting any damage to the vehicle is not their responsibility, all a tad off putting, especially when you see some cars being strapped down.
Is there not a more humane way of extracting this information, without having to buy a new engine ?

rolling roads these days are very kind to cars .. at one time you had to hold a load and wait for the reading to stabilise, write it down, go to the next 500 revs up and do the same, all teh way till past peak power .. cars were on rollers for 5-10 mins.
these days it's all over in 30 seconds, the computer calculates rolling losses, in truth it's as easy as it can possibly be these days.
as long as your car is in good health, oil and water checked, then there's negligable harm to be done .. rolling road operators are good at spotting potential danger like pinking too ..
but at the end of the day if it blows up, it's down to you to pay for any repairs and possibly cleaning the oily gunge from their workshop ..

Just make sure that it hads been warmed up before hand.

Emphasis on the OIL temperature NOT just the water temp.
BTW Darren, the dyno operator at Noble Motorsport told me last time I was there, that he's not testing any more cars with Nos after the last one 'blew up' on the dyno & he was sat above the tank at the time
