I'm in a flap

[rstoughy]

Dan,
What i noticed last night was not so much a loss in power but more of a slower delivery higher up the rev range. (and lack of noise)

The car would still squirm around while pushing hard out of slower bends but just seemed a little more refined so the power was still there just being delivered slightly differently. Does that make any sense? Might be one of that "you needed to be there moments".

Dan,

The flap has to open at some point - whether 'sport' mode selected or not. Foot to the floor in either mode still means that the flap is open which means equal power output. 'Sport' mode selection merely affects which throttle profile is used and determines at which engine RPM the flap opens. If 'Sport' is on the throttle response is slightly quicker and therefore has a (very small) affect on acceleration response.

I think Shimmy knows the RPM point at which the flap opens in each mode. It was on an old post somewhere on here...

Had mine off for over 2 years with no probs.

NO

If you floor gas pedal in Sport mode it will deliver 0-??bhp MORe at the rev range above the flap opening position (ie when the flap is closed in NON Sport mode). This is a gradual increase.

THis power will only be noticed in the rev range where the sport buttoin has an affect on the flap (something like 3500 and 5200 i think)

BUT if you flap is broken and it does not open at all the difference in bhp will continue up to the top of the rev range and makes a total difference of 30 bhp at the top end

when!?!

3 or 4 weeks ago. I was getting fed up with the press attention being one of the UK's longest serving CSL owners :hahaha:

All clear now Dan? :hahaha:

So no increase in power at all when open then?

Sorry Shim, was posting from the phone and didn't notice your post above thanks

Crystal mate! :bigcry: :hahaha:

Think I'll take the bugger out eventually by the sounds of things! (should have listened to you months ago) :bigcry:
