With DR or Slicks 60 fts are easy :-P, but it's pretty good for that little turbo saab (I assume it's the turbo LSJ since Saab does turbos lol)
No no, he's using SAAB 16" wheels for his drag radials. His car is an Ion Redline.

Turbo cars are less effected, however, the Roots type positive displacement supercharger is infact very much affected by atmospheric conditions.
Roots type are fixed drive ratios and have a given displacement and volumetric efficency, very much like a NA engine. At a given volumetric efficency, displacement and speed the supercharger will have less mass flow at lower atmospheric pressure.

While I understand that you say they have linear drive ratio due to being pulley driven. But is compensated when being compressed, hence while you'll make the same boost at sea level as when your 7,000 ft above sea level or more. I don't want to start a flaming contest, to each his own oppinion. Good 60 ft though

We can go through thermodynamic equations if you would like..

but stock is stock and we both are not.

Has anyone consistantly dropped a tenth off their 60ft simply by swapping from 215's to 225's? I cut a 1.9 on stock rubber and a 2.0 w/ 225's so I'm speaking simply from my own experience. I guess it attributes to the additional rotational mass and surface area...but who knows, it very well could have been the wind . I've just never been on a forum where people we're denied their legitimacy because they had a different tire brand or were +1 up in tire width lol. Drag radials and competition tires are a different story of course..

Lol...you guys are funny as sh-t...I am definately a stock REDLINE w/ a LSJ engine... The DA has a HUGE effect on the times/speeds. If you do the math (based on a perfect 0'DA, which only occurs in death valley once a year), I would have ran a 14.0 @97...so that is pretty fast for a Redline with just the GMPP 2.25" exh, and a CAI...thanks for believing me. Ill be out at the track again on the 2nd of Dec. So, hopefully Ill be able to re-produce that 60' with a faster E.T.

... To each his own like I said but I guarantee I'll run the same times I run here anywhere else. and the fact is slower cars have less power, less power means less chance of slipping tires less tires slipping, faster 60 fts. walk 60 feet it's not that far lol.

I can't believe this is still coming up. I posted the timeslip on here and had probably about 4 witnesses from the board and people still can't believe it.
for driver mod stage 5

They will be in the same "Other Power Adder" list as the Turbo'd cars and cars with NOS. Since there's no times yet with any of these, I haven't added the list yet. I will though.
#175
Ok guys. I think it's about time we have one of these. All times must be verified with a timeslip, you can e-mail them to me and I will update this. I'll keep track of the top 10.
Mods, will you please make this a "sticky"?
