I ran it for two weeks before it was mapped, and in that time it did not get thrashed. I had just changed lumps and wasn't going to risk the replacement going pop.

Wasn't a risk I was willing to take
Well at least you know you've done well in the piston lottery! If it had an imperfection on the ring lands you would know it by now. Lol.
Missed this comment earlier.
I agree it's an end of line mod. It does what it does quite well but then that's it. You can't get another 20bhp on top with hot cams like you can bodies because of the standard ecu and if you replace that you lose all the benefits of the rs2. It's a nice little finishing touch to a moderately specced car. Not the start of building a hero spec car.

Come on chaps, share your specs (including car)...
172 Cup with 58,000 miles on , KTR induction kit, decat, custom AAS 2.25" exhaust system. Its a flier on the road - was pleased to back it up with a good result on the rollers.
Impressive stuff although the graph is really small on my screen for some reason.
Whats the spec?
also I guess we should all be saying what we use our cars for, like trackdays or drag racing or just road cars etc so on that theme what do you use yours for?

172 turbo, fully forged, GT3071, VW box, Reno 5. Used on the road.
project thread http://www.cliosport.net/forum/showthread.php?279526-Renault-5-gtt-172-172-turbo-Project/page8
Unfortunately when BT pulled all the free webspace earlier this year all the pics were lost from the thread.
I normally only pay attention to the at the wheel figures on graphs.
Spec : super chip , power flow exhaust, matched inlet, viper intake
Spec : engine dynamics cams , jenvey 48mm bodies, power flow exhaust , 60 mm trumpets , standard injectors.
Winter plans are 120 mm trumpets , bigger injectors, raised comp, ported head and a 182 manifold hoping for a real 215 bhp and 170ftlb
One I wished the Clio had lol, my old focus rs

Trouble with that is that different roller types will measure differently for what classes as where the wheel is daft as it sounds.
On the run that Martin posted of his standard 172 for example, it only made 130 at the wheels on the maha, but the same engine on a dyno dynamics would no doubt do nearer to 150, the reasons is that the roller resistance itself is considered as part of the transmission figure so what they call at wheels is really after the bearings in the roller etc.
Also it doesnt take into account the temperature in the @wheels figure as its as measured.
TBH the harsh reality is that ANY comparison between different types of dyno is flawed and largely pointless, but @wheels figures even more so!
I assume despite what you said about @wheels you mean@fly for those figures?
On the dyno dynamics im used to using it would be 183@wheels to make 215@fly.
As it just uses a straight 15% loss, it doesnt attempt to measure it as there are so many flaws in doing so.
Main thing like you say is always use the same dyno if you want to know if the mods have really helped, the actual number is irrelevant its the % increase that matters IMHO, as the numbers are ALL meaningless, I dont claim the DD ones Im used to are more accurate than others as I dont know what the real power is, they are just what Im used to working with.

Freakishly good engine or expected figures for modifications?
There are a few 172 cups like that, millerin's, Emma.'s to name 2.
175lbft?
That doesnt seem realistic for that spec, do you have the graph as it sounds like the roller speed sync was wrong.
Good power though, and RS Tuning's rollers arent exactly famous for over reading, so it must go very well.
Turbo 182 Alfa 159
Yeah will get the graph scanned in after work. "Did" go very well, it dropped various valves a month ago lol. Hence stripping it in the for sale section
. Was a freak of an engine. Paul did say he was very impressed by its peak torque.

engines are like lightbulbs...
they always burn at their brightest just before they go pop!
Not just cups!
That torque curve suggests it's cammed IMO.
I was thinking the same earlier. Also peak power is close to 7k.
