View Full Version : Info needed for Hill Power RR feature please...
I need (from everyone that went on the rollers) the following information please...
Mods (nothing too in-depths please!)
Expected Output (yes, I know you have the figures now, but what were you all expecting. And please be honest :roll: :wink: )
And a quick comment about your figures.
Thank you :D
Supersprint manifold
Magnex decat
Magnex Cat back system
Green element
ChipWizards remap
expected power 151 @ the wheels - Actual power observed on day 146.8 @ the wheels.
Comments on figures.....................
I was happy with what I got, run a 151.3 @ the wheels 3 days previous when being remapped so 146.8 is about right, taking into account different rollers.
2.0l f7r
piper fast road cams
piper vernier pullies
mongoose ss cat back exh sys
bbpt de-cat pipe
1.8 16v exh manifold
itg panel filter
hillpower stage 2 chip( mapped to mods )
expected power was 145 bhp atw - actual fig was 141.3bhp atw
my comment on fig...
was a little disapointed with my result as it ran 145 atw when conversion was done, found out it is running lean topend, going back to hillpower to get modded fuelpump and supersprint fitted, also getting a remap again so should go up....
My mods were:
Viper Induction Kit
Gaz Suspension
Cat back Magnex
Not got a clue about my results as I don't understand them still :oops: and guess I never will lol
Marie :D

pm sent to you mate, didn't know what bhp to expect tbh.
devil straight through exhaust system
magnex de cat
i was told 130 bhp would be a good figure for the minor mods which i have
well being my first ever RR day i was very pleased with 134.1bhp @ 6,100rpm for the mods that the car has. nick hill was very pleased with the results too for the mileage of the car and the mods it had.
Maz - I'm quoting you on that!

This is for Duane.
1.8 16v
Mods: Magnex system with Hillpower de-cat and K&N 57i Induction kit.
Expected Bhp: Anything around standard 137bhp.
Comment: Well pleased with the result, 140k and still going strong.
Mat.
Mods: Scorpion System with a hole in the centre section.
Expected Bhp: Just under standard power (150bhp)
Comment: Power as expected. Made a few changes since (Started using BP Ultimate, new exhaust) and it feels much better again - just need to get back on the rollers to confirm! :)

Rsport ECU
Decat/Exhaust
BMC Induction Kit
About 150 atw
Quite pleased with the result as it has not been running 100%. Unplugged the ECU since and is much smoother so will have to get another RR done!
Chris
Cheers to everyone for the details so far :)
Maz - how about this....
It's more tiring going for a run in the summer than winter, because it's hotter. So if you were to test someone’s fitness to see if they’re improving throughout the year, you wouldn’t know how much is down to their fitness level and how much is because of different temperatures. An engine works in the same way - it makes more power when it's colder. So if you wanted to know if a modification works, it would be difficult to tell if it was from the mod or the weather changes.
To make it more consistent, some rolling roads take this into account and correct the figure according to weather outside. The figure that the rolling road actually reads the car is producing is called the observed figure. That’s how much power your car has made. This figure is then used to work out the corrected figure; this is the one which takes into account the conditions.
So what you have is corrected (according to the weather) and observed (what the dyno actually records from your car). They're measured at the wheels. Renault gets the 182 bit from the engine. To get the power from the engine, through all the cogs n oil in the gearbox, through the driveshafts and move the heavy wheels, some power is lost. That’s why it says you’ve got 150bhp (very roughly, 20% is lost) but the engine has actually got over 180bhp.

Just wondering.....if I wanted to go to Hill Power and go on the rollers, do you normally have to buy a chip or have a re-map or can u go on there just to get a general idea of what kind of power your producing without having these mods done. Matt 8)
dont think so mate? not much for a power run mate. give him a call for a price

Cheers m8....i'd like to get a general idea of how much power it's producing before I decide whether to go for cams + re-map etc.
