me and a friend have done pod a few times in our zs 180's and as far as we know we are the quickest 2 zs up the strip .
Earlier this year my best was 14.306 and his best was 14.254 both at 97ish mph and with 2.1 60ft times ,our cars are nasp and were making only about 200 bhp atf,,we strip them out and push them hard to get these times .There is now a couple of supercharged zs knocking about who say they are gonna kick our butts up the strip and they are making 260 bhp atf.
I have since modded my car to about 215 -220 bhp by adding piper fast road cams and have done a similar 14.3 but with a higher terminal ,however thanks to the poor grip on the day my best 60 ft was 2.4 ,so with my more usual 2.1's its looking like 14.0's or even 13.9's at 100 mph + is on the cards.
A nitrous zs has run several times with 200 bhp plus a 75 shot and best he ever got was 14.6 due to traction issues with the nos,i think the supercharged zs will suffer the same to a lesser degree,i.e struggling to lay the power in the lower gears so i think despite the lack of power i could still give them a run for their money.
The zs is quite light ,its only 1200-1220 kg's fully loaded so its not like its a big car to get rolling,especially when stripped to clio weight.

So what do you guys think ,who will set the quickest time,nasp or s.c?

Ultimately id say the supercharged, impressive times though.

It'll come down to who can put the power down most effectively at the start.

My n/a S2000 was doing 13.7s @ 103mph. My mate in his RX7 (390bhp) only just pipped me at the post with a 13.6 but his terminal was 109mph. In short once moving he was toasting me but I held him off for most of the way given I could effectively deploy full power in every gear. At around 1200kg, 60bhp extra is a significant advantage - I'd say you'll struggle.

the nasp has some advantages ,we strip ours out and they have said they dont need to strip theirs so we will be 120 kg's lighter,also the s.c makes peak power at only 6400 rpm ,mine makes peak power at 7200 rpm so i can pull longer in the same gear,my car spins in 1st 2nd and chirps the tyres going into 3rd so how will 40 more bhp cope with more torque as well.
i launch at 3500 rpm and that works well ,the supercharger isnt at its best at low revs so they have the dilemma of do they launch low and feed it in or build the revs more and risk spinning all the time away.
Tbh i think it will come down to how the cars deliver their power as when stripped the power to weight ratios aren't far apart.

what will your granny think , out hammering her rover up the strip
as for beating supercharged up a 1/4 mile, your dreaming

My experience of a supercharger (cooper S) was very good power delivery low down giving instant torque. I would reckon it would fair better than a turbo is such situations traction permitting.

Only one way of finding out really.
