Sudden burst of Torque on an R500D
Discussion
I've just run in a new R500, and have for the first time been able to give it some welly. I notice a huge and fairly sudden wave of torque at about 5.5k revs. Is that normal/common or should I be getting the ECU looked at at the 1000 mile service?
TIA

ETA I seem to remember a similar 'kick' in my R500K, but it was nothiung like as marked

its a problem I also have with my Duratec. Its a particular problem when overtaking in the wet or coming out of a corner on the limit in 4th gear and the backend lights up - all recovered of course with a dab of oppo.
I was considering putting a block of wood under the throttle pedal to reduce the powerr of the engine but I decided I would simply grin each time it happens instead
Hi Steve,
It's probably worth having another look at the attachment to the e mail I sent you in March. Does that look similar to what you feel yours is doing? Things have moved on since then and mine is a bit improved now but it's a long story. It may be finally resolved to as good as it gets now but I won't know for sure until I do another back to back comparison between the quiet and standard airboxes. If you want some more info drop me an e mail and I'll try and put you more in the picture.

Steve,
Worth checking that you are getting full opening on the Throttle Bodies, get some one to sit in the car and operate throttle pedal to full travel, whilst you look into trumpets with air filter off.
Sounds amazing but I was only getting 3/4 opening on mine due to how throttle stop screw was set.
Then check the balance of opening between,numbers 1-2 and 3-4 on the TB, again mine were way off, and they are easy to adjust too.
I will email you the pdf set up guide for TB that I used.
Nige.

Thanks for posting the photos guys, apologies again for the thread hijack. I need to finalise my spec for Thursday this week....
I'm leaning towards red with white decals just now but still like the white. The Crystalline white looks good but I think it's expensive over the powder white.
I guess there will be a lot of 2010/2011 cars in white and red with Superlight decals with the demonstrators/press photos being those colours.
