RR Results - RSTuner

[Chris Mac]

Had the car on the rollers yesterday, made 187.7.


the Cup has cone air filter set into standard air box with both feeds still on
KTec unsilenced decat
KTec full cat back 182 look syste
RSTuner 97ron and performance map

firstly, does this figure of a 16bhp increase seem about right for my mods?

and secondly, can anyone (HENK maybe) explain my massive drop in torque around 3000 RPM??

heres my graph

 

[JoedotwasT5phy]

16hp sounds alot. But not impossible, depends on your starting figure as they vary alot.

At a guess (i'm no expert) but the loss of torque @ 3k could be due to manifold pressure because of the cone filter. Just a guess though

 

[kevo66]

Does sound alot TBH mate!!

 

[Ali]

Did it run 171 std? Or are you assuming that?!

not a great curve tbh. My graph also Dastek with the same mods + Inlets. 186bhp.

 

[Chris Mac]

Why do your curves not cross, i think thats the first graph iv ever seen than doesnt cross....

 

[dzm]

Why didn't you do a run with the standard map first, then a run with the RSTuner after and compare them?

 

[Munson]

170 at the wheels seems extremely high to me TBH.

 

[TooneySonic]

hmm very strange curve this

what scale is the torque cant quite make it out, if its a small scale may be exagerating any dips...

seems a generous RR to me

 

[TooneySonic]

PMSL 170 at the wheels, just no!

 

[Andyman]

Standard runs 140 ish at the wheels roughly so high isnt the word

 

[MikeyK18]

Yeah, my car dyno'd at 179.7bhp last year at A.I. chris, my car was standard back then, which on a standard 172 is impossible.

A.I. rollers have been known to read quite high.

 

[TooneySonic]

186 at the fly, 170 at the wheels? Means roughly transmission losses of 8.9% healthiest ever lol lol lol

I think you need to speak to the operator and find out whats what

 

[Munson]

So, a ~30bhp wheel hp increase from a decat and a remap. I might get those mods done to my 182. Bingo! 205bhp.

 

[MikeyK18]

My readout from our RR day last year

 

[Tigger]

A.I. rollers have been known to read quite high.

We were all there & RR'd same day

Mine made 183.8 bhp!
At the time my 172 was completely standard all but a set of Turini's

All figures given as Max outputs

Wheels ~ 151.3 BHp
Engine ~ 183.8 BHp
Torque ~ 153.8 lbft

Given that a std 172 should be around 168bhp;
15bhp from a set of Turini's? Any wonder they're on almost every car on here :rasp:

NI RR day 24/02/08

Ahh the roller flamers! Yeah 170 atw seems pretty high, but other cars were pretty much bang on the money, mine was down on power than before with my torque sorted out which is exactly what i expected.

The 5th gear cup made 182 which is more than likely bang on with the bmc and full system. Same rollers, same day and plenty of people leaving unhappy that they didnt make the power they thought.

The ferarri 355 made ....... 355 doesn't get much more on the money than that imo.

However I will say as some rollers do tend to read different, it's only used as a guideline and the best way I can use the results are by using the same rollers everytime I get one done, that way the results can be compared against previous ones and mods based on that!

 

[Ali]

before and after BHP fella! lol. Well observed tho.

 

[TooneySonic]

The ferarri 355 made ....... 355 doesn't get much more on the money than that imo.

the 355 refers to engine size dude not power output, should be 376bhp iirc

I'm sorry but theres noway that car is making 170bhp at the wheels (ie given 17% trans losses 199bhp at the fly just roffle)

Haha FLOL!! The F355 is called F355 as its a 3.5 litre with 5 valves per cylinder, not because of its BHP! They should be 380bhp....... :rasp:

Dammit you beat me..... by like 5 mins. Where's my refresh button... lol

Didnt see that, I dont even make that

 

[_Tom]

My old tuned hybrid only made 153bhp atw and that was quick! There's no chance in hell thats making 170atw.

 

[Ali]

^ Liked that bus.Up there with the best Valvers to date.

 

[_Tom]

Yep she was sweet. Holds a special place in my heart.. Still that ran a 14.0 dead so a quick hybrid and was "only" 153atw on several RR's which is roughly 190bhp or so its generally worked out to be.

for a 172 to be 170atw it'd have to have ALOT of work..

 

[DCI_DUDE]

read some where (performance french car):

'It's said that the cup inlet manifolds were hand-picked, with only tht best castings being used. There's no evidence of this - exccept that jon says he's never seen a cup making less then 179 bhp !'

taken from the january 2009 performance french cars mag.

Haha brilliant, I must tell the guy that was roading his car for his friend. Not a ferarri buff myself

Slightly down on power or not, I think it would have been nice to hear a 355 on some rollers.

 

[The Chubby Pirate]

These rolling road threads make me pity them fools

If you make more than 185bhp the rollers are broken/inaccurate

If your car runs less than 170bhp, your cars fucked.

You cant win!

 

[Rock79]

Mine run yesterday on the same rollers

Wheels 171.2@6,725
Engine 188.5@6,773
Torque 156.1@5,610

Dont have a scanner 2 put the graph up, but it's got itg maxogen, Janspeed system & a de-cat. Does that sound out of the way. One of the mates had his civic on the rollers in ecc on Sat & there was only a difference of 1bhp compared 2 his run yesterday.

ignorance is bliss is all i'll say!

Not mate. Your car will prob be 140atw. It doesnt make fly power, at the wheels with simple mods. You'd be lucky with ALOT of mods. 170atw would be well into the 200's.

 

[TooneySonic]

Just to clear up with anyone who may be confused, AT THE WHEELS BHP is what matters, and is what a rolling road measures. The flywheel output is a calculated guess by the rr. I wont go into how those figures are worked out...

Anyway engine power is lost driving the tansmission so not all of the engines power makes it to the road!

Typically a fwd car like our clio's are known to have transmission losses of 17% give or take, so from a wheel BHP figure you can roughy calculate true flywheel power

The fact that these cars are making 170 at the wheels baffles me!!! Thats more than what a standard car makes at the flywheel!!!!! Or 200bhp at the fly no chance.

Go back and give the rr operator a slap!

 

[Chris Mac]

I love the way with all the bullsh1t spoken in this thread, noone has managed to actually post anything useful, nor answer my question

what a great website

 

[Andyman]

Even Renault got told bulls**t power figures hence the reason why the Sports are always down on power :rasp:

What part of no dont you understand ??

 

[TooneySonic]

well do you have a graph from the car before the mods to put up so we can compare????

IMO 16bhp is optimistic but all dyno's read differently.... On two diff sets of rollers my car made 193bhp and 177bhp with no changes!!

As for the torque thing i have no idea...., it seems to randomly spike...but i think the scale of the graph exaggerates it tbh

Anyway, stop being a little b**ch about it. We are pointing out that your rolling road operator has obv. made some sort of error to produce you torque spike and an at the wheel output of 30bhp up on where it should be!!!! GET IT??

Hi pal is there anychance you could scan up the graph, just curious to see if yours has the same torque spike???

we have a how much is my car worth sticky, time for a is my rolling road output accurate thread sticky pmsl with an education about RR's at the start

 

[Chris Mac]

Toony if your so concerned about the RR result, why not ring Ai Autosport and inform them, as your clearly an expert in the matter.

im asking why i have a large dip in torque at 3000 rpm

as in, is it a problem with the RSTuner remap?
