I've booked my 100HP to have 2 x Power Run's & to check any flat spots at the local Rolling Road in Reading on the 12th Dec.

I will post the results to show if there is any change to the BHP with an K&N Kit & custom Back Box added.

What results did you get before you fitted the items? Just so we can compare.

Looking forward to seeing those results!

I've not done a Rolling Road "Power Run" before.. 1 to 5bhp more is enough for me.

Your problem will be that you will not know if you have an increase or not.

If it helps my car (not a panda) is 121bhp standard. With the following mods:

Air filter
4-1 Manifold
Full exhaust system
Fast road cams (HKS 264's with 8.1mm lift)

On the rollers my car made 132bhp. So that's an 11bhp increase over standard. So I wouldn't expect too much.

I'll be amazed if there's any change, certainly no more than a ten degree change in the ambient temperature in the test area. I'm not even clear why there would be, as TDQ says, on a modern engine giving about 75 bhp per litre at the flywheel I suspect you'd need to change at least the complete exhaust system to see a fractional increase, with a change of cams giving you a bit more.

I saw an increase with a GSR induction, with rolling runs done on the same day - before and after fitting. However, it also smoothed out a few curves.

I now run a Group N Ragazzon back box with centre piece as well - although I haven't had a chance to RR it; I can't see the point now if I can't do a proper before and after run.

Stu what was your after with GSR? We've brought my misses a panda 100hp and having been looking at tuning avenues. See getting a GSR is pretty much a no goer now, but see the bmc cda kit looks ok and thinking about a raggazon system but not group n; don't want it too loud. Have you had yours remapped? From what I've searched on here most threads say the 100hp can't be mapped?!

No, I never had it remapped, mainly due to the issues and not wanting to go down that route again.

My graph is attached, although that is without the exhaust, which I had fitted a lot later on. I basically wanted a nice induction sound, although it also gave some favourable results.

I also had it lowered with Cobra Springs, as part of the deal with Evo mag.

the bmc cda kit is naff, better off with home made kit

:yeahthat: only cos of the price though. Can get similar cylinder filters a lot cheaper which do just as good a job

no its not Dave, it is very well engineered

a home made kit will not be well engineered, how will you do the custome silicone hose at home?

they are naff they get blocked with dirt very quickly, where as an open filter the dirt just falls off

even clean in back to back tests they don't come out as good as other cheaper kits

This morning had the Rolling Road session in Reading & my car pumps out 114bhp at the Flywheel & 103.6bhp at the wheels. Very happy with the results.

I was told by the guys I could have the engine remapp'd for £275.

The power curve graphs will be added in a few days to confirm the results & for all to see.

Setting up for the 1st run:

What sort of power upgrade would the remap make

Bet your happy with that, would be good to see the RR graph?

Good power output for what are relatively minor mods, so it seems money well spent. Would of course be interesting to see what a standard 100HP makes on those rollers though....

Looking forward to the graphs, as it will be interesting to see at what revs those figures are made - a 14% increase can really only be achieved by increased revs, so it should be producing max power at more than the std 6000rpm. Peak torque on the 100HP as standard should be 97ftlbs at 4,250rpm.

Which rolling road was this in the end?

Here are the Graphs,

The power at the Wheels:

At At the Flywheel



I was told there is may be a flat spot round about 5,000 rev's which could be the spark plugs which need changing (i've not changed them since i've had the car in Jan) or a sensor, the car is getting a 48k service at the end of this month by the local Fiat Dealer. I may take it back to the Rolling Road company (in Reading) in Jan & see if there is any change.

Sorry for the above graphs being so small. I hope u can increase ur zoom on here to view them properly.

Interesting graphs I must say - I'm quite surprised by what looks like 100ftlbs of torque at 2000rpm - you sure it's not a diesel!!

Proves the car is nice and healthy though. Shame it's not a 4WD roller, as I'd be interested to see what my car would record on this dyno.
