Hey guys,
My car is a '97 Z28 w/ a 350 ci. LT1, it has a supercharger w/ a 3,000 stall convertor, 3:73 gears, and 446 RWHP, and the car is still full weight.
Anyways, I went to an 1/8 mile track near my house yesterday. My best time was an 8.01 at 87ish MPH, and a 1.86 60' ft. time on drag radials. I was just wondering about what time I might be able to pull in the quarter mile with that 1/8 mile time. I probably wont get to a quater mile track for about another month so I am just curious. I know that some of you should be able to give me a good estimation about what that might convert to in a quarter mile.
Also, does that seem like a reasonable time considering what my mods and RWHP are? My torque was 521 with a locked convertor. This was also on a rather humid 85 degree day, so I would expect maybe a couple tenths less with better conditions. So please chime in and tell me if that time seems reasonable considering what I have done and what I might expect in the quarter mile. thanx in advance.

 

Take some weight off 12.2 in quarter mile 112 and get suspension done..

 

12.5 at about 108mph

 

One way to convert 1/8-mile performance to APPROXIMATE 1/4-mile:

ET@1/8 X 1.555 = ET@1/4
8.01 x 1.555 = 12.46-seconds

MPH@1/8 x 1.25 = MPH@1/4
87 x 1.25 = 108.8MPH

Looks a bit weak for 446rwHP. I've run (NA) mid 11's and 117mph with 390rwHP (non-locking converter - was 425rwHP with the M6).
