that time isn't at all bad for the mileage but i feel at sea level you should be capable of 13.60s but i am sure with more driving you will achieve a faster 1/4,my car at 2760' slp shorties,cai(homemade)and 18''goodyear f1's i ran 13.9 @99 60' was 2.11.

 

13.6s? maybe. I would be very happy with a 13.69 with my summitracing cutout that just got here today. I'll find out next friday and report back with a new thread. I am also going to take out the jack and spare tire. Also run on less gass, like maybe 1/4 tank rather than 3/4 like last time.

 

My first run ever with my car when it was stock was a 13.76 @102.8 with a 2.4 60' time... so it is most defenetly possible for some good times out of a stock car... although rare...

 

stock LT1's don't do 13.7 @ 103 with a 2.4 60'

sorry. not happening.

 

With just a CAI and my cat-back, i busted a 13.85 @ 101.8 mph. Just to give u a refrence. My car is an auto too.

 

I have the timeslip right here....

And I was off on 1 number... it was a 2.17 60' not 2.4.

Actaully have a video of part of it from someone on a local MB.

Only mod was a K&N airfilter, and Nitto DRs...

 

wow thats good time and mph. What is your car factory hp rating? Is it higher than the regular Z28s and T/As?

 

WS6 cars were 305hp in 96/97 Vs the std 285hp. Mainly due to the factory Ram Air; or more simply a much better intake design.

 

oh dang. Well yeah 13.7 stock is defiantly believable.

 

maybe with drag radials and a dead hook launch

a stock LT1's short fall is its top end. if it can get a dead hook then yes 13.7 is believable, but it won't be at much more than ~101mph.

 

Hey whatever you want to believe, I have the slip sitting at home in my office, video of it on my laptop, and about a dozen witnesses...

 

does "stock" include drag radials?

i would believe with a sub 2.0 short time then a 13.7 would be possible, but we all know how fun it is to get that on 245 50 street tires.

 

Not all LT1s came with mesly 245 tires.... some are the 275's stock...

Not to mention there is a difference between a "normal" T/A or Z/28 and a WS6 car...

 

sooo whats faster a '98Z or a '97SS ?

 

LT1's are just like LS1's they all put out about the same power, SS/WS6 or otherwise.

And a 1998 Z28 is faster than a 1997 SS.
