hi all

Just wanted to tell you all about my dyno run at Road Rage today. Met Leon who done it for me, really nice guy and very knowledgeable on Mercedes.
I have the V12 twin turbo and my only mod is a remap. Put some shell v power in it and had it dyno’d.

Figures are 589.3 hp and 834 lbs torque... extremely happy with that!!!

Thanks Leon for the dyno run!

Road Rage told me they where not in a position to dyno cars with more than 500bhp as their dyno trips the electric at those levels.

I assume they have sorted that now then!!

Any chance of a printout of the graph. Would be interested in the curves.

I assume that torque/bhp is back calculated using a fixed drivetrain loss % (probably 18% based on those numbrers?) Did you do before/after?

Thanks

so substantial gain and no doubt a whole lot more brisk to boot ?

definitely. I had it remapped a few months ago but was constantly raining when I went out in it so took a few weeks to notice the difference!

ill definitely get a pic uploaded. as for the before and after.. I had it remapped months ago by another company so no dyno before I'm afraid.

Thank you sir! Good looking curve. That dip at the end is due to the horrible stock airboxes.

I would take note of the peak torque curve which appears at 2000rpm (before the graph starts) would look like your peak torque is more like 750 lb-ft.

Its probably caused by the car shifting on the dyno when they put the pedal down.

I did think that was a bit high!
that was the second dyno pull... but the first pull I got 789.9 lbs torque at 3050 rpm
would that sound right then you think?

and is there an upgrade I could do to stop that dip? :)

That sounds more accurate. Although possibly taking into account a 20% drive train loss, which would be a bit high.

You would need some custom intakes, or something without the stock air boxes, its very difficult to fit stuff in the engine bay.

K+N drop in filters would help to some degree.

Unlikely to make a lot of difference (if any) if the problem is airbox design.
Remove the filters completely and see what difference that makes. That will show quickly if the filter element is causing a problem.

Its a combination of filter area and airbox design on these.

yeah very tight squeeze! I have found K+N filters on ebay but there 93 quid each! found same ones on a American site and there 95 dollars for the pair I think. I have had K+N before and felt some difference (could have had blocked filter before) but when I used the oil to "lubricate/clean" the filter, it messed up my MAF sensor... so wouldn't use the oil again on them for sure.
