182 Rolling Road results

[Custom Production]

So after recently purchasing my 182 for track use next year, I decided that before we started to spend money replacing things in the search for more power that we should run it on the RR to see what sort of power she is making. I run an ECU re-mapping company in south Yorkshire so it was without question that we should make some changes to the map on there to suit the mods the car already has. It has a dirty piper X air filter with no cold air feed, a gutted cat and a Scorpion cat back exhaust system.
After putting our stage 1 Re-map on here, raising the rev limit to 7100rpm as I simply could not stand the standard 6700rpm it achieved 190,2 bhp and 152.6 lbft
After looking at many other results people have had id say im pretty happy with these results at the minute given the cars state.
We could modify the fuelling further to get it running slightly leaner although im planning on making my own intake for it so were going to wait and see how the fuelling is with this.
Whats everyones thoughts
Thanks

190 is high with them mods tbf

Run 2 mad less fly power but more hp at the wheels?

 

[Dan@SJM]

Also the stock limiter is 7200rpm (except 4th and 5th that has a 7000)

The limiter on this car was 6700rpm

Was it poorly mapped previously before you fixed it? The rev limiter should be higher than that on a standard car

And what rollers do you use?

 

[Dan@SJM]

The limiter on this car was 6700rpm

That was on cold start enrichment then.

Remind me not to buy the OP's car 😂:wink:

It's fine, he's lowered the rev limiter by 100rpm. And it makes 190bhp on the cold map!

 

[Knuckles]

Don't be nasty to new members please

 

[masekwm]

On run 1 it runs less power at the wheels than run 2, but in run 2 it makes more power at the fly than run 1.
How does that happen?

 

[Dan@SJM]

It's an inaccurate way of testing really. They run up then let the rollers run down and measures transmission loss. Easy to forge results like this by doing stuff like touching the brakes to get transmission losses up.

 

[Custom Production]

So would you guys say ( without any sarcasm ) that this figure is in accurate because of the dyno ?

 

[bloke]

i would say the figure is hilarious!!!

 

[Custom Production]

Thanks for your input

 

[Dan@SJM]

Dyno dynamics do a fixed base losses, so wheel power +15%. Which puts yours at 164 and 166.

 

[Custom Production]

If any of you know what this even is then you'll see the original value of 6700 in purple code block 1 being the cars original rev limit. And im happy to take the car to another rolling road to confirm. The rollers we used here are well known around here and have always disappointed customers in the past believe it or not.

 

[Dan@SJM]

Yeh, that's the cold limit.

 

[bloke]

take it to chris at efi and stick it on his rollers...i'll even pay your fuel costs and pay for the power run.

 

[Custom Production]

what brings you to this conclusion ?

 

[Custom Production]

Where is the rolling road ?

 

[Knuckles]

That 7250 sounds about right for the oem Rev limit.

Runcorn mate

Ahh too far for me to travel there. Isnt there any you guys would recommend local to South Yorkshire ?

RS tuning in Leeds?

 

[Custom Production]

Yeah I could go there, any idea how much a run is there ?

 

[Dan@SJM]

Also, FYI, looking at the graph it looks like you're still running the closed loop fuel strategy. If you change that it delivers the power a lot smoother throughout and looses the pre 5k flat spot.

 

[Custom Production]

Are you a tuner ?

 

[Dan@SJM]

Amongst other things yes.

 

[Custom Production]

Nice one, what software do you use for tuning ?

 

[Dan@SJM]

Varies a lot tbh, but for these I'm quite happy with winols. Prefer standalone if I'm honest, no checksums to faff about with.

 

[RichieJA]

Sorry to but in here but I'm almost positive my 172 revs to around 7700 before it makes duh duh duhhh noise (rev limiter I assume) could that mean something is wrong ???

 

[McGherkin]

It'll be mapped. RSTuner goes to 7500 IIRC, some tuners go higher still to as much as 7800, but I wouldn't want to rev it quite that high personally.

 

[Dan@SJM]

Would indicate it's been mapped.

I had one come in with a 7900rev limit once... @Filters

 

[Custom Production]

Power starts dropping off at 7k It doesn't feel right any higher

 

[RichieJA]

Would indicate it's been mapped.

Ahhh thanks guy told me it was mapped and 190bhp
I absorbed that with a very large pinch of salt thou I swear its faster than my standard s3

It's very revy really kicks at above 5 I'm not used to such high revs I keep changing early.

Be careful when you throw figures around here mate people get offended

Only when they're not right.
