Surrey rolling road

[peanuthead]

Thought I would start a thread for anyone that went to surrey rolling road today and wanted to show their results.

Firstly here is mine, Totally standard 172 cup:

Pretty happy with the result

 

[Chip-mk1]

Looks pretty reasonable to me mate

 

[DannyR]

SRR is spot on from past experiences.

 

[peanuthead]

I was looking for anything more than 166 ish so really pleased.

 

[Christopher.]

 

[TimR26]

Both good results as most standard 172's are usually in low 160's at SRR.

Is that on ITB's and cams Dan?

 

[peanuthead]

Good result Dan you did look pretty happy with it. Was bloody loud on the rollers

How do you embed the photo!

 

[Dan519]

Use photobucket

 

[firthy182]

ok

 

[Fletcher]

Or just say what figures you got?

Shame I couldn't make it today :dapprove:

What's been done to that one firthy?

 

[firthy182]

438's, K-Tec induction kit, remap and a Piper exhaust. It goes nicely!

 

[Chip-mk1]

Cool stuff. Nice curve that.

 

[Millerin]

Ktec Decat
Ktec Stelth
JMS Remap
(At the time K&N Pannel Filter) now ITG Maxogen

 

[Andyrg@ ClioTurbo]

how did Laines go???

 

[Dan519]

250bhp 210lb/ft or thereabouts

How come the 172 cup and ph1 have such high readings? These are at the wheels results yes? When I went to rolling road day my 182 produced 149 at the wheels and others there produced less and some more. Just curious?
Cheers

These are flywheel guesses based on the rollers assuming 15% transmission losses.

So your 149/0.85 = 175
but comparing from different rollers is never accurate of course.

 

[Christopher.]

The Ph1 is standard apart from a ktec stealth.

 

[bass_direct]

My standard Williams made 153bhp

 

[Flat Eric]

Oooo I see. That's understandable then. Cheers chip for clearing that up

 

[firthy182]

Is this rolling road known to be an accurate one? As they are independent I would have thought it would be spot on.

Its very well respected mate yes. Although the previously mentioned fixed loss percentage for transmission is obviously never going to be totally accurate.
ALL rolling roads are flawed when it comes to guessing flywheel figures, but Surrey is as good as any out there IMHO, and at least by being totally independent of tuners you know they have no reason to exaggerate figures for certain cars etc like a tuner with a vested interest might get accused of.

 

[DannyR]

Same as Frost Motor Services, we've seen very accurate results which usually under read ~10bhp from K-Tecs when people had had work done there previously.

 

[Matthew]

Some strong results!

 

[Craig.]

Great results there.

I got 250bhp / 212ft lb, more than happy with that Ill upload graph when im back in Cornwall later.

Thing that shocked me most was the state of the fuelling on some peoples professionally mapped cars. The lines seem to resemble a rocky mountain range, poor!

Will be interesting to see how your graph compares to mine back when I first mapped it, as there is obviously quite a torque difference there.

Here is my one when it was running similar power to yours:

Yours must be hitting peak torque at 6K+ I guess?
