Stock 1LEs will not hit mid 12's without Drag Radials. They are capable of high 12s.
If you look at math we can get a good idea of what the Z/28 will do with a good driver. (and the magazines have already posted low 12s)
In the list above the best 60ft also has the best e/t (as it should). But for sake of argument lets use my time as a ref. as I know my cars weight and whp stock.
- My 1LE full weight is 3873lbs, Z/28 is in the 3830ish range: Delta of 43lbs
- My 1LE made 396whp on a Mustang Dyno, Z/28 made 448 on same dyno (months apart) so the Delta is about 42whp.
- The 1LE and Z/28 share the same trans/gearing and rear 3.91 gearing. The difference is the OD of the tires.
- When Motor trend swapped the Z/28 wheels on a 1LE they went from 13.0 in the 1/4 to a 12.7 E/T. Delta of -0.3 seconds (similar to adding a 4.11 gear to a 1LE with stock size tires)
So what does all the above mean?
Take my 12.991 run with a 2.155 60ft....(rough) math tells us that if I ran a 2.055 60ft I could have run
12.791
Take the
12.791 and add the smaller OD of the 305/30/19 which is worth about
-0.3 seconds......I am at a theoretical
12.491
Add the
42 whp advantage of the Z/28 and that 12.491 becomes (roughly) a
12.041
If both driver are the same weight and both cars have the same fuel in the tank you can take that
43lbs out now. 12.041 is now a
12.00 E/T
On a great day with a good driver that can cut a 2.0 60ft or better there is no reason the Z/28 cannot run a high 11s in the 1/4 mile.
Thank you for following my logic!
