I'm going with 2:40 as a consensus really fast lap time on road tyres. The last time I drove Spa was twenty years ago in a 993RS Touring; I don't think I even had lap timing kit then, and if I did, I've long lost the files. So I think I'll be happy if I can get with 10% of 2:40 on day 1 - something like a 2:56. Does that sound reasonable?
yeah, 2.40 sounds about right having just looked thru some footage of mine from back in March 2018 @ an RMA day, most laps between 2.40 to 2.50 depending traffic etc in my touring, and there was more to come but i was being sensible.

Gently bringing this thread back to its original purpose (or at least its new original purpose once I found out that RMA's Spa day was actually going ahead and I had to get my skates on)...

What do we think a good time looks like round Spa in a 1.GT3RS on Cup 2s? I find it slightly irritating that at least half the lap videos one can find are 12-year-olds on a playstation, not actual cars. Modern graphics are so good that it takes a moment to realise you're watching little Bradley work his thumbs while "dissing" someone else's mother over his headset. I suspect the 2:33's they boast of might be a little optimistic in the real world.

If you know the track well and having race experience you should rather get within 5% without much effort, just by dialling into the car on day one.

I'm setting my ambition modestly. Haven't done this in a long time and new to the car. To give you an idea, when I did Silverstone earlier in the year I got a shock because the GP track had been completely re-arranged since I last drove it. First time round I kept thinking "where's Bridge?".

We'll see...

You'll be doing well to get into the 2:41s. Possible 40s if you are very good. You seem reasonably competent and used to do some racing, you should be able to get under 2:50 reasonably easily and safely I'd have thought. Under 2:45s might take some work though....

Seen plenty of real life fast laps around 2:36.
Really? 991 3rs without cup2r doing 36s?

On Pirelli - https://youtu.be/EnA5Jj5bM4o

On Cup2 N2 - https://youtu.be/g9tOY9LxEPw

On Dunlop - https://youtu.be/MRVq2UsYfnQ

964 Cup’s car will be roughly equivalent to a .2 GT3 RS as it has KW 3-way competition, and is essentially an MR package car.

I’d be interested to see some of that footage, you have data overlay?

Yep be nice to see a 2.40 in a manual car for sure.

Makes a ton of sense not to put undue pressure on yourself - you'll be safer and faster wink

Watched one or two , using a lot of track , shame toe have such big run off areas now at Spa so everyone can push a bit harder without the fear of a big crash ....but guess it is safer , all on standard steel brakes as well . The EU guys seem to prefer that option

As to be expected, why would you not use all the track ?

the white car with Dunlops did a great lap did not go off track anywhere !

some one will post a 2.34 this summer on Cup R's one would say.

Have you seen any video of recent ie 2019 footage of the gen1 on N2 tyres out of interest? 2:40/41 was a very good time for the gen1 on N1 - it seems a bit implausible the gen2 is that much quicker just by the stated mechanical changes.

Ben,may be spa has changed since you were last there also,jump on a sim for a refresh.
Last time i was there racing in the masters historics in a 3.0ltr rsr on good tyres was a 2.50 qualy,mate in same type car went out on new tyres and banged in a 2.48,both on dunlop treaded historic spec tyres,so a modern car will be well with in this.
Cups go off fairly quickly for time hunting,from new 3 rd lap best and downhill from there,just keep it on the black stuff in that lovely purple motor.

I've got to learn the car anyway, so learning the circuit at the same time will be no hardship. I also have to remember how to drive at all. I have done one track day since 2005, and that was in my 964, in the wet. I did pack in quite a lot of circuit driving in the ten years prior to 2005, but who can remember that far back?

I have two days there, and won't be going for times on day 1.

[disclaimerincaseanyonefromRMAisreadingthis]it's a track day - I won't be going for times at all, of course[/disclaimer]

Tyres are fairly well used (and will have been driven there, too, so will be dirty for a while). I'm going to be happy with sub 3 mins on Thursday, and somewhere in the 2:50s on Friday. It's also going to be super-warm, apparently, so times will be slower. Assuming all is well and I get on with the car, I'm back in September and will try a bit harder then.

That Dunlop lap is proper. If that’s a 2.36 (in cool end Sept by the look of it), you will be going very well once you are sub 2.40s

I like how you are playing it down, but you’ll take about three laps to get into it and you know it smile
