[s-cars] 1/4 miles and clutches

[Calvin & Diana Craig]

Brian,

There is actually about 1 second difference between Bandimere (5800 feet)
and sea level.  The best I could do with my '87 Trans Am out here in CO was
about 1.2 seconds worse than sea level (14.5 vs. 15.7).  My Fomula 400 was
about 1 second slower (13.6 vs. 14.6).  For the S4 I can't imagine more than
about .2 to .3 seconds after driving it in both places (sea level and
here)...the boost pretty well washes it out and I haven't seen anybody post
a much faster time for a +2psi chipped S4 than the 14.9 I ran at
Bandimere....stock was 15.4.  For our next launch I will have to go
Temporary Duty to the Cape and I will take the S4 and get a direct
comparison...but launch isn't for another 3 years yet :)

Paul,
Sounds pretty familiar.  What a wonderful smell. I can slip my clutch in
1st from launch if I drop it from above 3500 rpm.  I bet your clutch has
lots of life left unless you keep doing the drag races.   My car, 91 200,
 with a Steve Eiche special chip and a garret T3/T4 hybrid turbo at 22 psi
can run 15.6s at Bandimare Speedway 7000' elevation.  Trap speeds were 92
mph.  I would like to know what it would do at sea level.  Some people
claim a full second difference for NA cars from 7000' to sea level.  The
most interesting car at the drag strip was a 7000+lb Ford F-250 diesel
running 15.0s.  He had nitrous and propane injection very cool guy, must be
a cousin of Haps.

<<<Paul's car has the MTM Stage 1+ chip and a Stebro exhaust from the cat
back.
Same 17" Avus though with 255 tires vs. my 235s, so probably slightly more
rotational mass.  As I recall, his last two runs were 15.13 and 15.15 sec
ET, with a trap speed of 97-98 mph.  I'll let Paul describe the first run
when he gets back.  I don't know.  Something to do with clutch not engaging
until 3rd gear.  It wasn't pretty.>>>
