SL500 R129 Rolling Road Results

[Willsco]

Went to Surrey Rolling Road last Saturday with some old Porsche 928 club friends and had my SL500 on the dyno.

Never been to a rolling road before - very interesting experience.

SL seemed to perform very well (IMO)

BHP - 310.6 (Original Spec is 306BHP)
Torque delivery - good
Air / Fuel Ratio - good

Car is 12 years old, just had a new MAF, was Terraclean'd six months ago and was running on Shell VMax fuel

I am sure there others on the forum who will be able to understand and interpret the graphs below far better than me

Any comments welcomed...

Nice results indeed, dare I say there could be a touch more to come with the AFR tweaked slightly between 3750-5000rpm , however you've got to be pleased with those results.

Yes, very pleased with results

Not adept enough to make any changes myself - so will probably leave as is and continue to enjoy!

Is the mixture not adjusted automatically??
