Done as requested!

Also to add Adam S for when you do the spectators. He's a Porsche passenger and is not permitted to bring his TVR Griffith 500, becuase it would either breakdown en-route or make all of our Porsches look "girly"!

So a Cayman S pdk is ok? There's folklore that the pdk in conjunction with PSM throws a wobbly on a dyno could be nonsense...??

[edc]

I don't know why that would be a problem if the RR can handle GTRs in various states of tune and all their electronic gizmos.

Oldbob - are you intending to run your car?

Room for one more? I'd be very interested to see how my old 7.1 2S with x51 compares on the charts.

PDK keeps trying to up shift (even in manual) on the dyno as the front wheels won't be spinning.

If you can roll th throttle progressive then floor it and hope it won't shift up you should get a run. Takes a good few attempts on the dyno's I've seen!

[Vixpy1]

PDK's can be done, they are a bit of an arse but eventually you get a good run out of them

[edc]

If you want to join in please can you also PM me your email address and car reg so I can revise the running order and contact you directly for further instructions nearer the day.

We have just about maxed out a half day now.

Lunch is being booked at a local pub for about 1.30 so any subsequent runners who want to lunch will have to join us immediately after their run.

I am sure Charlie will keep taking the cars all day long but as mentioned anyone signing up now will be on from circa 2pm.

edc, thx for the thoughts, I was only concerned with any warnings being thrown that weren't transient - ie needed a dealer trip to clear.
TheBob (my lad) and a I (OldBob) are booked in at SurreyRR this Sat am for a Cay R (his car with mods) vs a .2 CayS pdk (wifee car) comparison to get a relative measure of the difference or not of his mods.

We'll post results.

any results in yet?

A bit too early

Yep, 3 of us went to Surrey RR this morning.
Cayman S gen2 pdk; completely stock, has a very lazy life (DD for wifee)
Boxster Spyder pdk; stock but with "no baffles" in PSE
Cayman R manual; Evoms intake, IPD plenum, GT3 TB, Fabspeeed sport cat headers, Remus TI exhaust, Softronic map

The Cay R was dyno'd two weeks ago on a mustang dyno at ~372bhp, which seemed high.

All three were run one after the other
Results rounded:
Cay S pdk: 300bhp
Boxster Spyder pdk: 316bhp
Cay R manual: 346bhp

What to make of these...
Charlie expected the Cay S to be somewhere between 300 - 310 from past efforts.
The Cay S was the first run of the day
The first run was mid 250's and the following two both around 299
The car leads a sedentary life
Drag race vs the R, the R pulls on it significantly but the S doesn't feel slow

Both Cay's running with shell Vpower fuel

The Boxster spyder was up second and achieved close to published figures, on all 3 runs

The Cay R was third up and ran 3 similar around 345bhp

So depending on what you want to baseline and interpret against:
the R mods seem to have added somewhere between 20-35bhp
Certainly the R feels much faster than the other two, but for a lot of mods (cost) = max 35bhp increase, at least on SRR...oh and it sounds the t*ts too

Would be good to get the R down on the 5th.

Charts here:
chart used as background was 2nd run on S overlaid with the other two cars best runs, final S was 299.8 = ~300

All that said it probably puts the bhp/ton for the minimal weight R now firmly around 987.2 Carrera S territory
~266 bhp/ton.
So not only will it destroy one in the corners / on track but won't get out dragged in the straights now either... .. yeah I know, flame bait
The 991 Carrera engine is a similar 3.4 unit isn't it? This tunes the CayR unit to similar power/litre I think doesn't it?

I'll join if there is still space?
