Rolling Road Results
- Thread starter smok1n
- Start date
There are 100000000 topics on rolling road results, how innacurate they are & all the BS power claims out there so I'm going to keep this really short.
Russ' key words were "realistic." You can hope for mid 190s BHP all you want but the fact is you won't make a true 190 BHP with that spec on that engine. Shock horror 172s don't make 172 BHP as standard.
Rolling roads measure WHP not flywheel so they are essentially a very big estimating machine. Inevitably they tend to be setup to "overestimate" when you've just spent £1000 on a cams & map package to keep customers happy by thinking their car is now faster than everyone elses.

Looks like a MAHA 3000 dyno mate... hence the fly figure is derived from adding the P-Wheel and P-Drag figures together. The P-Wheel figure is not the at the wheel power as we tend to think of it. I'm no expert by the way, just passing on info I got from an operator of such a dyno.

HI,
yes it is MAHA dyno.
at the time the left drive shaft was alright but not in a very good condition i have replace it for new one will get the car to the rollers as soon i can, 2 see if affects performance.
i believe they are realistic gains, i would like to read more comments on it.
thankz 4 replys!
Clio sport cup
Had my 172 cup superchipped last year with just a ktec induction and a cat back system and that finished on 184.6 at the fly wheel, since then I've had ported inlets, de-cat and fitted a 64mm throttle body and you can feel the difference, once I've given it a full service ill get it on the dyno again and see what it's doing now
182
The 172 typically makes about 165 true bhp if its a strong one. The point of a rr is not to chase headline figures! Look at the drivability (torque curve/spread etc). If you are going to tune a car get a "base" figure first to work off so you know how much your money gets you. In the case of a clio very little!!
You now have this figure for future work...make sure you return to the same rr. With the same car on different rollers I had 177 then 193bhp

I think they need new rollers tbh
182 & LY Clio 220 ed
That the one in Brize Norton...comedians they were! (Lets pick a number...and plot a random chart on Excel!)
